Description

The present invention relates to an electrical stimulator used for treatment, rehabilitation, examination, massage, or beauty, or a conductor thereof.

Physical energy such as treatment using electromagnetic waves such as ultra-short waves and microwaves, treatment using low frequency and high frequency, electric potential treatment, treatment with weak current, or treatment with ultrasonic waves from the outside to the necessary part such as the affected area So-called physical therapy, which gives treatment, massage, or beauty treatment, is attracting attention, and many medical devices, diagnostic devices, training devices, and beauty devices that realize these are in practical use. In many of these, the above physical energy is supplied to the human body by an instrument used in contact with or in close proximity to the affected area or the like. The device is referred to herein as a guide. And in the present specification, physical energy used for treatment, beauty or diagnosis, for example, current or voltage or power having an AC component such as ultra-short wave, microwave or pulse, current or voltage or power having no AC component, laser. , Ultrasonic waves, etc., or each is called electrical stimulation or treatment pulse. Alternatively, a combination of electrical stimulation, such as a combination of low frequency and ultrasonic waves, is also simply referred to as electrical stimulation or therapeutic pulse. Therefore, it can be said that the guide is used to supply electrical stimulation to the human body.

Most of the above guides are fixed to the human body and used. As a fixing method, there are a method of attaching the conductor to the affected part and its surroundings with an adhesive pad, a method of wrapping the conductor around the affected part with a belt, a method of adsorbing the conductor to the human body with a suction cup, a method of fixing the conductor to a stand or an arm, and the like.

There is a problem in each of the above methods of fixing each conductor. In the type of guide that uses an adhesive pad, there is a hygiene concern that the adhesive pad is used by a plurality of people. Furthermore, the problem of burns and pain due to the decrease in conductivity due to the deterioration of the adhesive pad and the accompanying current concentration occurs. Alternatively, in treatment or training in which a plurality of four or six guides are used at one time, the position where each guide is attached is defined, which makes the attachment complicated. The method of fixing with a belt tends to cause poor contact when it is difficult to make good contact with the human body over the entire conductor. It is not desirable to tighten the belt strongly in order to maintain good contact, and problems such as congestion and poor blood flow due to overtightening of the belt may occur. In the method using a stand or an arm, even if the patient moves a little, the position of the affected part and the guide is shifted, so that the treatment efficiency cannot be maintained sufficiently continuously and the treatment efficiency cannot be improved.

On the other hand, in the method using a suction cup, a sponge containing water is usually placed between the affected area and the electrode in the cup. Concerns are easily remedied. A plurality of electrodes are arranged at predetermined positions in the cup in advance, and there is no complexity of attaching the electrodes to the affected area. Since no adhesive pad is used, no problems occur due to deterioration of the adhesive pad. Since the belt is not used, poor contact of the electrodes by the belt and overtightening of the belt do not occur. Since it is not necessary to fix the patient with a stand or an arm, even if the patient moves a little, the guider does not move relative to the affected area and the treatment efficiency does not decrease.

Hereinafter, in the present specification, treatment devices, medical devices, massage machines, diagnostic devices and beauty devices that use electrical stimulation are collectively referred to as electrical stimulation devices. Treatment and diagnosis using an electrical stimulator, massage, and treatment with a beauty device that uses an electrical stimulus are collectively referred to as treatment. A person who performs treatment using an electric stimulator, a person who makes a diagnosis using an electric stimulator, or a person who performs a beauty treatment using an electric stimulator is called a user, and a person who receives treatment is called a patient. Furthermore, the part of the human body that is treated by electrical stimulation is called the affected area. Therefore, unless otherwise specified, the description of the electrical stimulator does not exclude massagers, diagnostic equipment, and cosmetological equipment, and even if it is described as a patient, it may mean only those who have an injury or illness. It does not exclude those who undergo examinations and those who undergo cosmetology treatments. Similarly, the description of the affected area does not mean only the part with an injury or disease, but does not exclude the part of the body to be examined or the part of the body to be subjected to cosmetological treatment. As described above, the electric stimulus does not exclude the ultrasonic wave, and therefore, the therapeutic device using the ultrasonic wave, the diagnostic device using the ultrasonic wave, or the beauty device using the ultrasonic wave is also included in the electric stimulating device.

Japanese Unexamined Patent Publication No. 2002-143321 WO2008 / 069266

As described above, the method using the suction cup is desirable as a conductor or as a method of fixing the conductor because problems that occur in other conductors are improved, but has the following problems. One of them is the increase in size and cost of the equipment. The suction cup cannot be used alone, and generally requires a separate device called a suction unit. The device uses a mechanical suction pump to expel the air in the cavity formed by the human body and the suction cup by applying the suction cup that constitutes the transducer to the human body, and generates negative pressure to generate the suction cup. It is a device for adsorbing to the human body. The device is supposed to be used in the environment where it is used, for example, in a hospital or in a facility where cosmetology is performed, and since quietness is important, sound insulation performance must be excellent. It is difficult to reduce the weight and weight, and cost increase is inevitable. Further, the mechanical suction pump inevitably requires large vibration and is required to have static vibration, and it is unavoidable to increase the cost of vibration countermeasures.

In the suction unit for discharging the air in the cavity, a general suction pump is not suitable for use due to the following reasons. As described above, a sponge containing water is usually used between the electrode and the human body in the suction cup. When the water contained in the sponge is sucked into the suction pump by the suction of the suction pump, the suction pump is damaged by the water, or even if it is not damaged, the suction pump often fails. Was there. Alternatively, rust is likely to occur even if the moisture does not cause immediate damage or damage, making it difficult to extend the service life. As a countermeasure, a dedicated pump with waterproof measures is required to prevent damage, damage, and rust even if water flows in, which leads to further cost increase.

On the other hand, Patent Document 1 described above proposes a method of sucking a suction cup on a human body without using a suction pump. However, the techniques described in this document require a blower pump that sends air instead of a suction pump. Furthermore, since the pump by this method discharges air directly from the suction cup, the sucked water becomes water droplets and is discharged to the outside of the suction cup, which may be scattered on the patient's skin, wet clothes, or cause discomfort to the patient. May give. Even in a suction unit that uses such a blower pump, as long as the blower pump is a mechanical pump, it is necessary to take measures against the generated noise and vibration, which has been a major cost increase factor.

An object of the present invention is to solve these problems and provide a quiet, inexpensive, and compact suction device and conductor.

(1) In order to solve the above problems, the present invention has taken the following measures. That is, it is an electrical stimulator having a conductor that supplies electrical stimulus to the human body and an exhaust portion having an ultrasonic vibrator, and the exhaust portion is the air inside the cavity formed by the conductor and the human body. Is discharged from the cavity.

(2) Further, the electric stimulator of the present invention has a plurality of the exhaust units, and also has a control unit that controls the suction force of the conductor by controlling the number of exhaust units to be used.

(3) The electrical stimulator has a control unit that controls the suction force by changing a parameter that determines a drive pulse that drives the ultrasonic vibrator.

(4) It has an inflow suppression unit that reduces the amount of water flowing into the exhaust unit.

According to the present invention, since the ultrasonic vibrator is used, no human-recognizable driving sound is generated, and no vibration is generated. Therefore, it is not necessary to take measures against the driving vibration and the driving sound peculiar to the pump. Furthermore, since a large pump is not required, the device can be miniaturized. Alternatively, even if water flows into the device, it is atomized by the ultrasonic vibrator, so that a problem due to the inflow of water does not occur and a highly reliable device can be made.

An embodiment of the present invention will be described with reference to the drawings. In the present embodiment, an electrical stimulator that performs treatment using a low frequency pulse will be described as an example, but not only a low frequency pulse but also a high frequency pulse, an ultrasonic wave, an electric potential, a laser, an ultrashort wave, and a microwave are electrically stimulated. It may be an electric stimulator used as an electric stimulator, or an electric stimulator used in combination thereof.

(First Embodiment)
In the present embodiment, the present invention will be described by taking as an example a low-frequency treatment device and taking as an example an electrical stimulator having an exhaust portion composed of an ultrasonic vibrator. In particular, in the present embodiment, the suction unit is incorporated in the main body.

FIG. 1 is a perspective view of the main body 11 of the electrical stimulator 1a used in the description of the present invention in the present embodiment. The main body 11 of the electrical stimulator 1a includes a main power supply 12, a pilot lamp 13, three buttons for determining the treatment mode, a mode button 15a, a mode button 15b, a mode button 15c, and an LED 18a linked to the mode buttons 15a to 15c. It has an LED 18b, an LED 18c, a connection unit 23a and a connection unit 23b for connecting a separately described conductor to the main body portion 11, a dial 21a and a dial 21b for changing the output frequency, and a volume 14 for changing the output. In addition to this, the main body 11 has a power cord connected to the AC power supply, a power supply board for generating DC power from the AC power supply, and other parts necessary for treatment, but the description is omitted because they are not essential parts of the present invention. do. The inside of the main body 11 is divided into upper and lower parts at the positions of the dotted lines in FIG. The main body 11a on the upper side of the dotted line has various operating means such as the main power supply 12 and mode buttons 15a to 15c, display means such as pilot lamps 13 and LEDs 18a to 18c, and a control device and a power supply board described later. The lower main body portion 11b is a portion where the connecting portion 23a and the connecting portion 23b are arranged. The main power supply 12, the mode button 15a, the dial 21a, and the volume 14 function as operating means. Further, the pilot lamp 13, the LED 18a and the like function as display means.

The electrical stimulator 1a of FIG. 1 can perform treatment by supplying two types of low-frequency pulses to the affected area using two sets of electrodes at the same time, that is, a total of four electrodes. In other words, the electrical stimulator 1a has a 2-channel output. The number of channels is not limited to two, and may be one or more, and may include, for example, three channels of output. Alternatively, it may have a configuration of 4 channels or more.

FIG. 2A is an enlarged view of the connection portion 23. Since the connection portion 23a and the connection portion 23b have the same configuration, the description of the connection portion 23b will be omitted. The connection portion 23a has an intake port 201, a first electrode connection 202, and a second electrode connection 203. FIG. 2B shows a connector 204a connected to the connection portion 23a, which is composed of an intake terminal 205 having an annular cross section, a first electrode terminal 206, and a second electrode terminal 207, and the connector 204a is connected to the connection portion 23a. By connecting the above, the intake port 201 and the intake terminal 205 are connected, the first electrode connection 202 and the first electrode terminal 206 are connected, and the second electrode connection 203 and the second electrode terminal 207 are connected, respectively. The intake terminal 205 is connected to a hose 208 having an annular cross section, the first electrode terminal 206 is connected to the harness 210a, and the second electrode terminal 207 is connected to the harness 210b. These hoses 208, harness 210a, and harness 210b are connected to a guide 301a described later.

FIG. 3 shows a cross-sectional view of the conductor 301a. The hose 208, the harness 210a and the harness 210b are connected to the guide 301a by a joint portion 303a on the upper portion of the cup 302 which is a cup portion. The hose 208 is used to suck the air in the cavity 310 formed by the cup 302 and the human skin 309 and exhaust it to the outside of the conductor 301a by the opening 307a at the tip and the opening 307b provided in the cup 302. Will be done. A pedestal 304 is provided in the cavity 310, that is, in the cup, and the first electrode 305 and the second electrode 306 are arranged in the pedestal 304. The first electrode 305 and the harness 210a are connected, and the second electrode 306 and the harness 210b are connected by a pattern 311a and a pattern 311b provided on the pedestal 304. The sponge 308 is arranged so as to contain water between the first electrode 305 or the second electrode 306 and the skin 309, and the treatment pulse supplied to the first electrode 305 or the second electrode 306 via the sponge 308 is sent to the skin 309. Is supplied to the affected area. When supplying electrical stimulation to the affected area, a guider 301b (not shown) having the same configuration as the guider 301a is used, for example, the guider 301a and the guider 301b are sandwiched between the guider 301a and the guider 301b. Place and treat.

FIG. 4 is a diagram showing a main body portion 11b that functions as a suction unit, and is a cross section of the main body portion 11b viewed from above. As shown in the figure, the main body 11b is provided with a shielding region 401a and a shielding region 401b at the connecting portion 23a and the connecting portion 23b, respectively. Since the shielding area 401a and the shielding area 401b have the same configuration, only the shielding area 401a will be described. In the shielding region 401a, the exhaust port 403a is provided with an exhaust unit 402a, the exhaust port 403b is provided with an exhaust unit 402b, the exhaust port 403c is provided with an exhaust unit 402c, and the exhaust port 403d is provided with an exhaust unit 402d. The air in the shielded area 401a is exhausted to the outside of the shielded area by the exhaust units arranged at each exhaust port, and the air in the shielded area 401a is discharged to the outside of the shielded area by, for example, the exhaust unit 402a provided in the exhaust port 403a. A negative pressure is generated in the shielding region, and the air in the cavity 310 formed by the guide 301a and the skin 309 is exhausted through the hose 208 connected to the connection portion 23a, and the guide 301a discharges the air from the skin 309. Adsorbs to.

A partition wall (not shown) is provided between the main body 11a and the main body 11b, and the air discharged from the shielding area 401a and the shielding area 401b is arranged in the main body 11a as a power source, a board, and a switch. It may be configured so as not to affect the above. In particular, in the configuration in which the conductor used has a sponge 308 containing water as shown in FIG. 3, the air flowing into the shielding region 401a from the intake port 201 is the air discharged from the openings 307a and 307b of the conductor 301a. As such, it may contain water retained in the sponge 308. When the moisture is discharged from the exhaust portion 402a and the like to the outside of the shielding region 401, it is exposed to the parts in the main body 11a, for example, the substrate and the electronic parts, causing an electrical short circuit, causing the device to malfunction or the parts. The board and parts may be deteriorated even if it is not damaged or a short circuit occurs, and the main body 11a and the main body are not affected by the air discharged from the cavity 310 inside the main body 11a containing many electric circuits. It is desirable to arrange a partition wall between the portions 11b.

FIG. 5A shows a cross section of the exhaust portion 402a. The exhaust section 402a and the like are composed of a piezoelectric pump 501 having an ultrasonic vibrator that performs ultrasonic vibration, suck air in the shielding region 401a from the intake section 502, and exhaust the air from the opening 503 of the piezoelectric pump 501. The ultrasonic vibrator is also called an ultrasonic element, a piezoelectric vibrator or a piezoelectric element, and may be a piezo element or the like, and in the present specification, these are referred to as an ultrasonic vibrator. The piezoelectric pump 501 can operate and exhaust air according to the principle described in Patent Document 2, for example. The piezoelectric pump deforms the ultrasonic vibrator by applying a pulse to the arranged ultrasonic vibrator, expands the space where the ultrasonic vibrator is placed, sucks air into the space, and ultrasonically vibrates. By inverting the pulse applied to the child and deforming the ultrasonic vibrator in the opposite direction, the space is contracted, and the air sucked into the space is discharged at once to act as a blower or a pump. Can be done. Although detailed description of the principle is omitted here, by using the piezoelectric pump for the suction unit of the electric stimulator, the following effects can be obtained as compared with the case of using the conventional mechanical pump. The first is tranquility. The exhaust portion 402a is not mechanically driven such as rotating or sliding, has no mechanical driving portion, and does not generate any mechanical vibration. Further, the driving portion only emits ultrasonic waves, and humans cannot recognize the ultrasonic waves, and cannot recognize the driving sound of the piezoelectric pump 501 of the exhaust unit 402a. Therefore, there is no need to take any measures against the driving noise and vibration of the pump itself like the conventional mechanical suction pump, and hospitals and beauty facilities do not have to take any measures to suppress the sound or vibration of the pump itself during driving. Can be used in.

In addition, the piezoelectric pump is usually several cm square, has a thickness of several millimeters, and weighs several grams. Therefore, the exhaust portion 402a can also be made extremely small and lightweight. For example, 2 cm square, thickness 3 mm, and weight. It can be composed of about 2 g. Therefore, unlike the conventional suction unit, it is not necessary to configure the suction unit separately from the treatment device, and the treatment device and the suction unit can be integrally configured. If the exhaust capacity of the exhaust unit 402a is insufficient, a plurality of exhaust units may be arranged as in the present embodiment. In this embodiment, four exhaust units are used in combination from the exhaust units 402a to 402d. Since the exhaust units 402b to 402d have the same configuration as the exhaust unit 402a, the description thereof will be omitted. The number of exhaust units is not limited to four, and may be one or more, two or three, or five or more.

Further, the piezoelectric pump used for each exhaust unit is not limited to one, and each exhaust unit may be configured by using a plurality of piezoelectric pumps. For example, two piezoelectric pumps are stacked or arranged side by side to form one exhaust unit, and four exhaust units are arranged as shown in FIG. 4, that is, eight piezoelectric pumps are arranged and used together. May be good.

Further, since the piezoelectric pump 501 constituting the exhaust unit 402a has an ultrasonic vibrator, even if water flows in from the conductor 301a, the water is only atomized by the ultrasonic vibrator. , Unlike the mechanical pump, the pump is not damaged by moisture, no waterproof measures are required, and it is desirable as a suction device for a conductor using a sponge containing moisture as in the present embodiment.

However, when a large amount of water can flow in at one time, for example, when the sponge 308 contains too much water, the excess water reaches the exhaust portion 402a using the hose 208 and becomes super-in the exhaust portion 402a. It may adhere to the ultrasonic vibrator, making it difficult for atomization by the ultrasonic vibrator to occur, and making exhaust difficult. In such a case, an inflow suppressing unit may be arranged in the exhaust unit 402a or the like to temporarily suppress the inflow of water, in other words, to disperse the inflowing water. A porous member such as a sponge may be arranged as the inflow suppressing portion. The inflow suppressing unit only needs to suppress the inflow of a large amount of water into the intake unit 502 at one time, that is, the amount of water flowing in at one time can be reduced or reduced, and a shielding plate is arranged in addition to the porous member such as a sponge. But it may be. FIG. 5B is an example in which the shielding plate 504 is arranged. As the shielding plate, for example, a shielding plate 504 made of aluminum or stainless steel may be used. The shielding plate 504 may be attached to the exhaust portion 402a, or may be integrally made of resin with the exhaust portion 402a. With the shielding plate 504, for example, even when a large water droplet rides on the air flow to the intake portion 502 and reaches the intake portion 502, the water droplet is dispersed in all directions by colliding with the shielding plate 504. By dispersing the water in smaller water droplets, it is possible to temporarily prevent a large amount of water from flowing into the intake unit 502.

As described above, in the inflow suppression unit, the flying water droplets reach the piezoelectric pump 501 along the flow of air from the conductor 301a and directly jump into the piezoelectric pump 501, that is, a relatively large amount of water is temporarily discharged. It suffices if it can be prevented from flowing into the piezoelectric pump 501, and by temporarily holding water like a sponge or reducing the moving speed of water, it is possible to temporarily prevent a large amount of water from flowing into the piezoelectric pump. Or a configuration such as a shielding plate that disperses water droplets flying along the air flow to temporarily prevent a large amount of water from flowing into the piezoelectric pump.

Therefore, the inflow suppression part may be a rubber blade or a resin plate in addition to a sponge or a metal plate such as aluminum or stainless steel, and the shielding plate is not limited to a flat plate, but is convex, concave, corrugated, or the like. It may have a structure having random irregularities or protrusions, a hemispherical shape, or a bent structure. Alternatively, the shielding plate may be configured to be tilted with respect to flying water droplets. Alternatively, the shielding plate may have one or more small holes.

Alternatively, a plurality of desirable features as a shielding plate may be combined. For example, as shown in FIG. 5C, the shielding portion 505 may be arranged as an inflow suppressing portion. The shielding portion 505 has a plate surface inclined and has a protrusion 506 at a part, that is, at the right end of the drawing. With this configuration, when a relatively large water droplet flies and collides with the shielding portion 505, it is dispersed into smaller water droplets, and the water droplets mainly scatter to the left toward the drawing due to the inclination and directly flow into the intake unit 502. Even if the scattered water droplets are scattered to the right in the drawing, the protrusions 506 can reduce the water droplets that directly flow into the intake unit 502.

The inflow suppressing portion to be arranged is not limited to one type of sponge, shielding plate, and shielding portion, and a shielding plate, sponge, or the like, or a configuration in which the shielding portion is used in combination to form the inflow suppressing portion may be used. ..

The inflow suppression unit may be arranged at the intake unit 502 or at the intake port 201. Alternatively, it may be arranged on the guide 301a. That is, it may be configured in the flow path of the air discharged from the cavity 310. For example, it may be arranged in the openings 307a and 307b. Further, although it may be arranged in only one place of the place illustrated by these, a plurality of places may be arranged in these places.

When a plurality of inflow suppressing portions are used, a sponge or a shielding plate may be used as all the inflow suppressing portions, but it is also possible to use a sponge or a shielding plate for a part and a shielding plate for the rest. For example, a sponge may be arranged between the openings 307a and 307b, and a shielding plate or a shielding portion may be arranged in the intake portion 502 as shown in FIGS. 5 (b) and 5 (c).

As described above, since the exhaust section 402a and others use a piezoelectric pump using an ultrasonic vibrator, basically, when water droplets enter the piezoelectric pump, they are atomized by the ultrasonic pump and exhausted. However, for example, when the atomized water is directly exhausted from the main body 11, the patient or the user may mistakenly think that the atomized water is smoking or may ignite even if it is water vapor. many. Therefore, in the present embodiment, as shown in FIG. 4, the exhaust gas is once discharged into the main body 11b and then discharged from the exhaust slot 404 to the outside of the device. That is, the main body portion 11b, which is a suction unit, is configured to have an exhaust retention portion 405. In FIG. 4, inside the main body portion 11b, the shielding regions 401a and 401b correspond to the exhaust retention portion. With this configuration, the air discharged from the exhaust port 403a and others by the exhaust unit 402a and others is in the main body 11b, that is, in the suction unit for a certain period of time even when it contains atomized water. After staying and the water vapor becomes invisible or very difficult to see, it is discharged from the exhaust slot 404 to the outside of the device. Therefore, the exhaust is not mistaken for smoke by the user or the patient. The exhaust gas retention portion is not limited to the above, and a separate region may be provided.

In the device using the piezoelectric pump as described above, there is no operating noise as described above, but air noise or wind noise (hereinafter referred to as exhaust noise) is generated by the air exhausted from the opening 503 or the like. It may occur. In this case, an exhaust noise suppressing portion such as a diffuser or a rectifying plate may be arranged in the opening 503 or the like to suppress or eliminate the exhaust noise. In FIG. 5B, a dome 507 is arranged as an exhaust noise suppressing portion.

FIG. 3C shows an example in which the rectifying unit 508 is arranged as the exhaust noise suppressing unit. As a result, the exhaust noise can be reduced or eliminated.

Further, the dome 507 is provided with a finer muffling port 509 as an exhaust sound suppressing portion. In this way, one or more muffling ports 509 may be arranged as the exhaust noise suppressing unit. Of course, if the exhaust noise can be sufficiently suppressed only by the dome 507, it is not necessary to provide the muffling port 509. The dome 507 has an opening on the left side when facing the dome, but the dome 507 is not limited to this, and the exhaust noise suppression portion may be configured by arranging the dome as a closed dome and arranging a large number of muffling ports in the dome. ..

Further, a plate in which one or more muffling ports 509 are arranged may be arranged instead of the dome 507 as an exhaust sound suppressing portion. The muffling port 509 is not limited to the dome 507, and a rectifying unit 508 may also be provided so that the rectifying unit 508 and the muffling port 509 can be used together.

The exhaust noise suppressing portion is not limited to these, as long as the exhaust noise can be suppressed or eliminated, a sponge may be arranged in the opening 503, or a new member may be separately arranged as the exhaust noise suppressing portion. Instead, the configuration as shown in FIG. 4 may be used. That is, in the configuration of FIG. 4, even if the exhaust noise is generated, the exhaust noise is only generated inside the main body 11b, and the exhaust noise is not leaked to the outside of the main body 11 or is suppressed to be very small. Therefore, the exhaust noise suppression unit can be configured most easily without adding a new member. In this sense, it can be said that the exhaust staying portion 405 is an exhaust noise suppressing portion.

As described above, according to the present invention, since the pump using the ultrasonic vibrator is used, there is no mechanical driving component, and the reliability can be greatly improved. Furthermore, since humans cannot perceive the driving sound and vibration of the pump, soundproofing and vibration-proofing measures are not required. In addition, the device itself can be made very small and lightweight. Further, it is not necessary to take measures against the water by the pump except for the measures against the inflow of a large amount of water temporarily, and the damage caused by the water can be avoided.

FIG. 6 is a block diagram of a control device 601a built in the main body 11a, which mainly controls the main body 11. In addition to the control device 601a, a power supply unit (not shown), a transformer (not shown) that supplies electrical stimulation for treatment to the conductor, and the like are built in the main body 11a, but this is directly related to the present invention. Since it is not related, the description is omitted. The operation unit IF602 in the figure is connected to the main power supply 12, the volume 14, the dial 21a, etc., and controls information indicating what kind of setting the user has made to the main unit 11 or how it has been operated. Notify department 603. The control unit 603 notifies the display unit IF 604 of information for displaying the setting, the operation status, and the like according to the information from the operation unit IF 602. The display unit IF604 displays such as turning on the necessary LEDs according to the information. In the present embodiment, the display unit IF 604 is connected to a pilot lamp 13, an LED 18a, or the like, and is turned on according to an operation or a setting state. In the present embodiment, the operation means and the display means are separately provided, but the present embodiment is not limited to this, and for example, a touch panel may be used to simultaneously perform the operation and the display.

In the electrical stimulator 1a of the present embodiment, when the main power supply 12 of the main body 11 is pressed, the information is sent from the operation unit IF 602 to the control unit 603, and the control unit 603 sends the pilot lamp 13 to the display unit IF 604 so as to light the pilot lamp 13. An instruction is given, and power is supplied to the pilot lamp 13 according to the instruction, so that the pilot lamp 13 lights up.

Subsequently, the user selects and operates any of the mode buttons 15a to 15c to select the treatment mode. In the present embodiment, mode 1 is a mode in which a low frequency pulse having the same frequency is used as a treatment pulse for the first electrode 305 and the second electrode 306 of the conductor 301a, and mode 2 is a mode in which the first electrode 305 and the second electrode 306 are used. Is a mode in which pulses of different frequencies are applied to, and mode 3 is also a mode in which pulses of different frequencies are applied to the first electrode 305 and the second electrode 306, but the treatment pulse applied to the second electrode 306 is predetermined. It is a mode that is swept within the range of. These three modes are linked to the mode buttons 15a to 15c, and when the mode button 15a is pressed, mode 1 can be selected, when the mode button 15b is pressed, mode 2 can be selected, and when the mode button 15c is pressed, mode 3 can be selected.

A frequency of about 30 Hz to 800 Hz is determined by the dials 21a and 21b as the frequency of the treatment pulse actually applied. For example, when mode 1 is selected, the frequency selected by the dial 21a is applied to the first electrode 305 and the second electrode 306, and in mode 2, the frequency of the pulse applied to the first electrode 305 is the dial 21a and the second. The pulse applied to the electrode 306 is selected with the dial 21b. In mode 3, the frequency of the pulse applied to the first electrode is applied to the first electrode 305 by selecting it with the dial 21a, and the frequency is sequentially changed within a predetermined range with respect to the frequency selected with the dial 21a. It is applied to the second electrode 306.

The intensity of the treatment pulse applied to the first electrode 305 and the second electrode 306 is determined by the volume 14. The setting contents set by such an operation means are input to the control unit 603 via the operation unit IF 602, and the control unit 603 displays by the display means via the display unit IF 604 according to the input. At the same time, the control unit 603 inputs the set information to the treatment waveform generation unit 605, and based on the set values, the first electrodes 305 and the second electrodes 305 and the second electrodes are used as treatment pulses from the waveform outputs 606a and 606b via a transformer (not shown). It is supplied to 306.

In the present embodiment, when any of the mode buttons 15a to 15c is selected, the information is supplied from the operation unit IF602 to the control unit 603, and the control unit 603 supplies the piezoelectric pump to the piezoelectric pump control unit 607a based on the information. Is instructed to drive, that is, to drive the exhaust unit 402 and the like. According to the instruction, the piezoelectric pump control unit 607a supplies power to the drive pulse generation circuit units 608a to 608d, which are drive pulse generation circuit units that generate pulses to drive the piezoelectric pump, activates each drive pulse generation circuit unit, and activates the piezoelectric pump. A drive pulse (hereinafter referred to as a drive pulse), for example, a drive pulse having an amplitude of about 14 Vpp at a frequency of about 30 kHz is generated. The drive pulse is supplied to a piezoelectric pump constituting each exhaust unit, for example, a piezoelectric pump 510 constituting the exhaust unit 402a, by outputs 610a to 610d provided in each of the piezoelectric pulse generating circuit units 608a to 608d. For example, the drive pulse generation circuit unit 608a is supplied to the exhaust unit 402a and the piezoelectric pump of any of the exhaust units provided in the shielding region 401b. Hereinafter, similarly, the drive pulse from the drive pulse generation circuit unit 608b is supplied to one of the exhaust units provided in the shielding regions 401a and 401b via the output 610b to drive the piezoelectric pump of the exhaust unit. By doing so, the exhaust unit is driven to attract the conductors 301a and 301b to the patient. Similarly, for the remaining piezoelectric pumps, outputs are supplied from the drive pulse generation circuit units 608c and 608d to the remaining exhaust units. The frequency and amplitude of the drive pulse are not limited to the above, and may be appropriately set according to the characteristics of the piezoelectric pump and the water atomization conditions. Alternatively, the control may be such that the drive pulse is switched over time. For example, when the optimum frequency and amplitude for suction and the optimum frequency and amplitude for atomization of water are different, these frequencies and amplitudes may be switched manually or automatically.

In the present embodiment, the suction of the guide 301a and the guide 301b is linked to the mode button 15a and the like, but the present invention is not limited to this, and may be linked to, for example, the volume 14 that controls the output. The control unit 603 may be controlled so that the conductor 301a or the like is attracted only when the output is set to other than zero by the volume 14. Alternatively, an on / off switch for instructing the start or stop of adsorption may be separately provided to control the start or stop of adsorption of the conductor 301a or the like.

By separately arranging the suction force operating means for controlling the suction force in the present embodiment, the suction force can be easily controlled. In the present embodiment, four exhaust units are arranged, so if the suction force is too large, the suction force can be controlled by not operating one or more of the exhaust units. That is, the suction force of the conductor 301a and others can be controlled by controlling the number of exhaust units to be driven or the number of piezoelectric pumps. For example, a toggle switch that can select two types, strong and weak, is arranged as the suction force operating means, and when strong is selected, all four exhaust parts are driven, while when weak is selected, 1 It is also possible to control not to drive the individual exhaust units. For example, the information on which weak is selected is input to the control unit 603 by the operation unit IF 602, and the control unit 603 instructs the piezoelectric pump control unit 607a to use only three exhaust units according to the input. The piezoelectric pump control unit 607a drives only the exhaust units 402a, 402b and 402c of the shielding region 401a according to the instruction, and supplies electric power only to the drive pulse generation circuit units 608a, 608b and 608c so as not to drive the 402d. In this way, the adsorption force of the conductor can be easily controlled, and the pain and redness of the skin that occur when the adsorption force is too strong can be reduced or eliminated. In the above, the control of the adsorption force is limited to two stages of strong and weak, but is not limited to this, and may be three stages of strong, medium and weak, or more.

Further, the control of the suction force is not limited to the case where the number of exhaust units or piezoelectric pumps used is changed as described above, and the amplitude, frequency, duty and other drives of the drive pulse output from the drive pulse generation circuit unit 608a and the like are driven. The parameters that determine the pulse may be changed. Compared with the control by the number of exhaust units to be driven as described above, it is possible to control the parameters defining the drive pulse of the piezoelectric pump more flexibly and with a high degree of freedom. Further, the suction force may be controlled by changing the parameters of the drive pulse and the number of exhaust units used.

The drive pulse parameters are changed by the control unit 603, supplied to the piezoelectric pump control unit 607a, and output 610a by changing the power and frequency supplied to the drive pulse generation circuit unit 608a and the like by the piezoelectric pump control unit 607a. The drive pulse output from another may be controlled. Alternatively, the piezoelectric pump control unit 607a may control the parameters of the drive pulse by inputting to the piezoelectric pump control unit 607a how much the control unit 603 controls the drive pulse. In this sense, the control of the drive pulse is performed. It may be performed only by the control unit 603, may be controlled by the control unit 603 and the piezoelectric pump control unit 607a, or may be specifically controlled only by the piezoelectric pump control unit 607a.

In the present embodiment, for example, in FIG. 6, four drive pulse generation circuit units are arranged to drive the piezoelectric pumps arranged in each exhaust unit, but the present invention is not limited to this. For example, using only one drive pulse generation circuit unit, the drive pulse may be supplied from the one drive pulse generation circuit unit to the piezoelectric pumps arranged in each exhaust unit.

In this case, in order to control the number of exhaust units, a switch (not shown) is arranged between the drive pulse generation circuit unit and the exhaust unit as an attraction force operating means, and the switch is controlled by the piezoelectric pump control unit 607a. By doing so, the number of exhaust units used may be controlled to control the suction force of the conductor. Alternatively, the suction force may be controlled by using the switch and the change of the drive pulse parameter together.

Further, as the above-mentioned suction force operating means, it is described that the number of exhaust units or piezoelectric pumps to be used is controlled or the parameters of the drive pulse are changed, that is, the capacity of the suction unit itself is controlled. Although the explanation is given, the present invention is not limited to this, and for example, a slit that can change the open / closed state is provided as a suction force operating means in a part of the conductor 301a, the main body 11b, or the connector 204a, and the slit can be opened or closed. Alternatively, the suction force may be controlled without changing the operating ability of the piezoelectric pump itself by changing the degree of opening.

In the above embodiment, the suction unit made of the piezoelectric pump is formed integrally with the main body portion, but the present invention is not limited to this, and the suction unit may be separated from the main body portion 11 and configured as a separate body. The suction unit to which the present invention has been applied has the above-mentioned various merits even when it is configured as a separate body, and has soundproofing, vibration-proofing, and vibration-proofing as compared with the case of using a conventional mechanical pump. In addition to eliminating the need for waterproof measures, it is possible to provide a suction unit that is much smaller and lighter and at a lower cost. In such a configuration in which the suction unit is a separate body, the suction unit can be used in common even when the electrical stimulator such as the treatment device to be used is changed, so purchase as many suction units as the number of treatment devices. In some cases it is not necessary and desirable.

When the suction unit is provided as a separate body, the switch for controlling the start and stop of suction and the suction force operating means for controlling the suction force described above are not the main body 11 but the separate suction unit. It may be provided in the unit, or it may be configured such that the suction unit operates in conjunction with the operation of the main body 11 by connecting to the main body 11. Further, as described above, the suction force operating means may be provided in the main body of the electric stimulator, in the suction unit, or in the conductor. When it is provided on the guide, both the user and the patient can easily control the suction force, so it is more desirable that it is not necessary to move to the main body or the suction unit provided separately. The suction force operating means may be configured not only to control the suction force but also to have the above-mentioned on / off switch function to control the start and stop of suction.

(Second embodiment)
In the present embodiment, a configuration in which a suction unit is arranged in the guide portion is shown. The difference from the first embodiment is that a suction unit composed of an exhaust unit 402a or the like is arranged in the guide. That is, in the first embodiment, the exhaust portion is arranged in the main body portion 11b, but in the present embodiment, the exhaust portion is arranged in the guide.

FIG. 7 shows a cross section of the conductor 301c, which has a configuration in which a suction unit is arranged in the conductor portion. In this figure, the same reference numerals are the same as those of the above-mentioned parts and the like. For example, reference numeral 305 is the same as that of the first electrode 305 in FIG. 3, so the description thereof will be omitted. The guide 301c is provided with four exhaust portions 402a to 402d in each of the four joint openings 701a to 701d provided inside the wall surface of the joint portion 303b. In the figure, only the joint openings 701a and 701b and the exhaust portions 402a and 402d are shown for the sake of simplicity, but the exhaust portion 402b is provided on the inside of the wall surface of the joint portion 303b on the front side of the paper surface corresponding to the joint opening 701b. The exhaust portion 402c is arranged inside the wall surface of the joint portion 303b that opposes the exhaust portion 402b so as to correspond to the joint opening 701c. At the time of treatment in which electrical stimulation is supplied to the affected area, a guider 301d (not shown) having the same configuration as the guider 301c is used, and for example, the affected part is arranged so as to be sandwiched between the guider 301c and the guider 301d for treatment. The harness 210c is connected to the main body portion 11c, and supplies drive pulses to the exhaust portions 402a to 402d by an electrode pattern (not shown) arranged inside the joint portion 303b.

In the conductor 301c, the exhaust portion 402a and the like are arranged on the conductor. As described above, since the exhaust unit is composed of a piezoelectric pump using a very small and lightweight ultrasonic vibrator, the suction unit can be integrally configured with the conductor like the conductor 301e. In this sense, the joint portion 303b functions as a suction unit. By integrally configuring the suction unit with the guide in this way, a hose for securing a flow path for exhaust from the cavity 310 to the exhaust portion 402a and the like, such as the guide 301a, becomes unnecessary.

A suction cup type plunger, for example, a suction cup 301a or the like, has a suction unit for discharging air in the suction cup to generate a negative pressure in the suction cup. In the first embodiment, the main body 11b and the suction cup A hose is essential in between. However, the hose needs to have a certain thickness to secure the air flow path, and also needs to be strong so that the flow path is not easily crushed or bent by air pressure or twist. If the strength is insufficient, there is a potential problem that the hose is easily twisted or bent, the hose is crushed, the air flow path cannot be secured, and sufficient exhaust cannot be performed. For this reason, the hose became thick, heavy, or difficult to bend, and was not easy to handle. Furthermore, the thickness, weight, and inconvenience of handling become a burden and load directly applied to the conductor, and the suction force of the suction cup must be increased more than necessary so as to withstand the weight of the hose. Strong adsorption causes problems such as the patient feeling pain due to suction and causing redness of the skin. If the suction force of the guide is low, the weight of the hose makes it easy for the guide to come off, and even if the suction cup does not come off, the treatment pulse from the electrodes placed in the suction cup cannot be sufficiently supplied to the affected area. It led to a decrease in the number of patients and poor treatment.

Due to the above factors, the suction unit must generate a suction force much stronger than the suction force required to suck the suction cup due to the hose, and a pump stronger than necessary is required, which is usually several tens of centimeters. It was four-sided and weighed several kilograms, sometimes requiring the same cost as an electrical stimulator.

However, since the hose is not required for the guider 301c or the like, all the problems caused by the hose can be solved. For example, even if the suction force is significantly lower than that when a hose is used, the conductor 301c does not come off during the treatment, and neither pain nor redness of the skin occurs due to the excessive suction force. On the other hand, since there is no hose, a part of water can easily reach the exhaust portion 402a or the like on the sponge 308. When used in the opposite direction to that shown in FIG. 10, that is, when the exhaust portion 402a is used so as to be below the cup 302, the water content of the sponge 308 easily reaches the exhaust portion 402a. However, as described above, since the piezoelectric pump constituting the exhaust unit 402a uses an ultrasonic vibrator, the water is atomized and exhausted as water vapor, and water droplets may be scattered to the patient or wet the patient's clothes. do not have.

FIG. 8 shows the main body 11c of the electrical stimulator 1b that uses the guide 301c and the guide 301d. The difference between the electrical stimulator 1a and the electrical stimulator 1b is that the connecting portion 23c and the connecting portion 23d are arranged in the main body portion 11c instead of the connecting portion 23a and the connecting portion 23b. Other reference numerals are the same as those of the main body 11a, and the description thereof will be omitted. Since the connecting portion 23c and the connecting portion 23d have the same configuration, the connecting portion 23c will be described.

FIG. 9A is an enlarged view of the connecting portion 23c. The difference between the connecting portion 23a and the connecting portion 23c is that the common pulse connection 902 is arranged instead of the intake port 201. In the common pulse connection 902, the common pulse terminal 903 and the common pulse connection 902 are coupled by connecting the connector 204b of FIG. 9B and the connection portion 23c, and the exhaust portion 402a and other exhaust portions are connected via the harness 210c. A drive pulse is supplied to the piezoelectric pump 501 arranged in. The other harnesses 210a and 210b are connected to the joint portion 303b, and further connected to the first electrode terminal 206 and the second electrode terminal 207, respectively.

FIG. 10 shows a control device 601b built in the main body 11c. In this figure as well, the same reference numerals as those in FIG. 6 will be omitted because the explanations will be duplicated. The difference from FIG. 6 is that only one drive pulse generation circuit unit 608e is used and the piezoelectric pump control circuit unit 607b that controls the drive pulse generation circuit unit 608e is used. The piezoelectric pump generation circuit unit 607b drives the drive pulse generation circuit unit 608e according to the instruction of the control unit 603. The drive pulse generated by the drive pulse generation circuit unit 608e is output from the output 610a and supplied by the harness 210c to the piezoelectric pumps arranged in the four exhaust units 402a and others. Further, the drive pulse is similarly supplied to the piezoelectric pump of the exhaust portion arranged in the conductor 301d.

Even in a configuration such as the conductor 301c, it is possible to control the adsorption force as described with respect to the electrical stimulator 1a in the first embodiment. As described above, the suction force operating means for controlling the suction force can be separately arranged to easily control the suction force. For example, the adsorption force of the conductor 301c may be controlled by changing the frequency and amplitude of the drive pulse, the duty, and other parameters that determine the waveform of the drive pulse.

Since the control of the suction force is executed by controlling the parameters, for example, a volume (not shown) may be arranged on the main body 11c or a volume may be arranged on the conductor 301c as the suction force operating means. , The parameters of the drive pulse may be changed.

Alternatively, a switch (not shown) is separately arranged on the conductor 301c as a means for operating the suction force, and the switch is turned on / off to control the number of exhaust parts used to control the suction force of the conductor. You may. Alternatively, the suction force may be controlled by using the switch and the change of the drive pulse parameter together. The suction force operating means may be configured not only to control the suction force of the conductor 301c or the like, but also to have an on / off switch function to control the start and stop of suction.

Although only one drive pulse generation circuit unit 608e is used in FIG. 10, a plurality of drive pulse oscillation circuits may be provided and used. For example, as shown in FIG. 6, the configuration may be such that four drive pulse oscillation circuits 608a to 608d are used. Alternatively, the piezoelectric pump control unit 607b and the drive pulse generation circuit unit 608e that control the exhaust unit or the suction unit are not provided in the main body 11c, but are arranged in a suction control unit (not shown) separate from the main body 11c. It may be configured. That is, the main body 11c may control the electrical stimulation, and the suction control unit may control the drive pulse of the suction unit or the exhaust unit.

Further, in addition to each exhaust portion 402a, the sponge, the shielding plate 504, or the shielding portion 505 may be arranged as an inflow suppressing portion. Alternatively, an exhaust noise suppressing unit such as a dome 507 or a rectifying unit 508 may be arranged in addition to each exhaust unit 402a. A configuration in which both the inflow suppressing portion and the exhaust noise suppressing portion are arranged may be used.

Further, as the above-mentioned suction force operating means, it is described that the number of exhaust units or piezoelectric pumps to be used is controlled or the parameters of the drive pulse are changed, that is, the ability itself as a suction unit is controlled. However, the present invention is not limited to this, and for example, a slit or window whose opening / closing state can be controlled is provided as a suction force operating means in a part of the conductor 301c to open, close, or open the slit or window. By changing the degree, the suction force may be controlled without changing the operation of the piezoelectric pump itself. Further, as described above, the suction force operating means may be provided in the main body of the electric stimulator, the suction control unit, or the conductor. When it is provided on the guide, both the user and the patient can easily control the suction force, so it is more desirable that it is not necessary to move to the main body or the suction unit provided separately.

(Third Embodiment)
This embodiment is the same as the second embodiment in that the suction unit is provided on the conductor, but the drive pulse generation circuit portion is provided on the conductor portion instead of the main body portion of the electrical stimulator. That is different from the second embodiment.

FIG. 11 shows a cross section of the conductor 301e. The conductor 301e also has a configuration in which a suction unit is arranged in the conductor portion. In this figure, the same reference numerals are the same as those of the above-mentioned parts and the like. For example, reference numeral 305 is the same as that of the first electrode 305 in FIG. 3, so the description thereof will be omitted. Like the conductor 301c and the like, the guide 301e is provided with four exhaust portions 402a to 402d inside the wall surface of the joint portion 303d. The method of use is the same as that of the guide 301a, the guide 301c, etc., and the guide 301f (not shown) having the same structure as the guide 301e is used, and the affected part is adsorbed by the guide 301e and the guide 301f. And give electrical stimulation to the affected area. The difference from the conductor 301c and the like is that the drive pulse generation circuit portion 608f is arranged inside the upper surface of the joint portion 303d and is connected to the main body portion 11d via the harness 210d.

FIG. 12 is a main body 11d of the electrical stimulator 1c using the conductor 301e. The difference from the main body portion 11c is that the connecting portions 23e and 23f are arranged in place of the connecting portion 23c and the like. Since the other reference numerals are the same as those of the above-mentioned parts and the like, the description thereof will be omitted.

FIG. 13 (a) shows the connector 204c that connects the connecting portion 23e, and FIG. 13 (b) shows the connector 204c that connects the connecting portion 23e. A pulse power connection 1301 is arranged in the connection portion 23e, and is connected to the pulse power terminal 1302 on the connector 204c side, and is connected to the pulse power terminal 1302. The power required for this is supplied to the conductor 301e via the harness 210d. Since the other reference numerals are the same as those of the above-mentioned parts and the like, the description thereof will be omitted.

FIG. 14 shows a control device 601c built in the main body 11d. In this figure as well, the same reference numerals as those in FIG. 6 will be omitted because the explanations will be duplicated. The difference from the control device 601b is that the circuit unit that generates the drive pulse of the piezoelectric pump, for example, the circuit unit corresponding to the drive pulse generation circuit unit 608e in FIG. 10 is not arranged. The drive pulse generation circuit unit is instead arranged on the conductor 301e as the drive pulse generation circuit unit 608f. In the present embodiment, when the piezoelectric pump control unit 607b attracts the conductor 301e, the drive power of the drive pulse generation circuit unit 608f is output from the output 610e, and the drive power is supplied to the conductor 301e via the harness 210d. As a result, it is supplied to the drive pulse generation circuit unit 608f arranged inside the joint unit 303d, and the drive pulse generation circuit unit 608f is activated. When the drive pulse generation circuit unit 608f is activated, a drive pulse is generated, and the drive pulse is supplied to each of the exhaust units 402a to 402d by an electrode pattern (not shown) arranged inside the joint unit 303d. Each piezoelectric pump 510 is driven, exhaust is executed by the exhaust portion 402a or the like, and the air inside the cavity 310 is discharged, so that a negative pressure is generated inside the cavity 310 and the conductor 301e is adsorbed. The piezoelectric pump control unit 607c may not be provided in the control device 601c as shown in FIG. 14, that is, in the main body 11d, but may be arranged in a suction control unit (not shown) separate from the main body 11d. That is, the main body 11d may control the electrical stimulation, and the suction control unit may control the drive pulse of the suction unit or the exhaust unit.

In the second embodiment, the drive pulse output from the drive pulse generation circuit unit 608e is supplied to the conductor 301c or the like via the harness 210c, so that the very long harness 210c may serve as an antenna. Electrical noise due to the drive pulse is likely to be generated from the harness 210c. The noise can be avoided by changing the impedance of the drive pulse generation circuit and the parameters of the drive pulse, but if it is not sufficient, it is necessary to use a coaxial cable having a shielding function as the harness 210c, which increases the cost. The harness 210c may be heavy.

On the other hand, in the present embodiment, the drive pulse generation circuit unit, which is the drive pulse generation circuit unit of the piezoelectric pump, is arranged not in the main body unit but in the conductor 301e. Therefore, there is no member that functions as an antenna, and the above-mentioned electrical noise is not generated or is very small, which is more desirable.

Further, in the present embodiment, instead of the piezoelectric pump control unit 607b and the harness 210d, a power extraction unit that extracts power by rectifying the treatment pulse supplied by the harness 210a or 210b to the conductor 301e or the like, for example, a rectifier circuit or the like. (Not shown) may be arranged to drive the drive pulse generation circuit unit 608f by the electric power extracted from the treatment pulse. In this configuration, the piezoelectric pump control unit and the harness 210d are not required, so that the device is further equipped. It is possible to reduce the size, weight and cost.

Also in this embodiment, as described in the second embodiment, it is possible to control the adsorption force. As described above, the suction force operating means for controlling the suction force can be separately arranged to easily control the suction force. For example, the conductor is controlled by providing a switch, a volume, or the like on the conductor 301e as an attractive force operating means so that the frequency and amplitude of the drive pulse, the duty, and other parameters that determine the waveform of the drive pulse can be changed. The adsorption force of 301e may be controlled.

Alternatively, the main body 11d is provided with a separate suction force operating means, for example, a volume or a toggle switch, and by changing the volume or toggle switch, the control by these suction force operating means is performed via the control unit 603 via the operation unit IF602. And the information is sent to the piezoelectric pump control unit 607b. The piezoelectric pump control unit 607b changes the amplitude value of the drive pulse by changing the power supplied from the output 610e to the drive pulse generation circuit unit 608f, for example, the DC voltage value or current value of the power, or the amplitude or frequency of the AC component. The attractive force of the conductor 301e may be controlled by indirectly controlling the parameters of the drive pulse such as changing the frequency or changing the frequency to control the piezoelectric pump arranged in the exhaust unit 402a or the like.

In such control, when DC is supplied as electric power, the drive pulse generation circuit unit changes the parameters of the drive pulse, for example, the amplitude value and the amplitude, in accordance with the voltage and current value of the DC electric power. It may be configured in. When AC is supplied as electric power, the drive pulse generation circuit unit is configured so that the parameters of the drive pulse, such as frequency, amplitude, duty, etc., are changed according to the amplitude and frequency of the AC power. good. Alternatively, when the AC power is offset by the DC component, the drive pulse parameter may be changed according to the offset value.

Alternatively, a switch (not shown) may be separately arranged on the conductor 301e, and the switch may be turned on / off to control the number of exhaust units to be used and control the suction force of the conductor. Alternatively, the suction force may be controlled by using the switch and the change of the drive pulse parameter together. It should be noted that the suction force operating means may be provided with the function of these on / off switches so that the start and stop of suction can be controlled.

Although only one drive pulse generation circuit unit 608f is used in FIG. 11, a plurality of drive pulse oscillation circuits may be provided and used. For example, as shown in FIG. 6, the configuration may be such that four drive pulse oscillation circuits 608a to 608d are used. Further, as described above, the suction force operating means may be provided in the main body of the electric stimulator, the suction control unit, or the conductor. When it is provided on the guide, both the user and the patient can easily control the suction force, so it is more desirable that it is not necessary to move to the main body or the suction unit provided separately.

Further, the above-mentioned sponge, the shielding plate 504, the shielding portion 505, and other inflow suppressing portions may be arranged in addition to each exhaust portion 402a. Alternatively, a dome 507, a rectifying unit 508, or another exhaust noise suppressing unit may be arranged in addition to each exhaust unit 402a. A configuration in which both the inflow suppressing portion and the exhaust noise suppressing portion are arranged may be used.

Although the embodiments of the present invention have been described in detail with reference to the drawings, the specific configurations are not limited to those described above, and various combinations and other combinations and other combinations are made without departing from the gist of the present invention. It can be applied to electrical stimulation equipment. For example, the following development is possible.

FIG. 15 shows an ultrasonic conductor 1501 which is a conductor for supplying ultrasonic waves to the affected area. The ultrasonic conductor 1501 is basically the same as that in FIG. 11, but an ultrasonic head 1502 having a built-in ultrasonic vibrator is arranged instead of the first electrode 305, the second electrode 306, the pedestal 304, and the like. A pulse of, for example, 1.6 MHz or 3 MHz for driving the ultrasonic vibrator is supplied to the ultrasonic vibrator in the ultrasonic head 1502 by the harness 210a or 210b to generate ultrasonic waves.

FIG. 16 shows an ultra-short wave conductor 1601 which is a conductor for supplying ultra-short waves or microwaves to an affected area. The ultra-short wave conductor 1601 is basically the same as in FIG. 15, but an ultra-short wave head 1602 is arranged instead of the ultrasonic head 1602, and the affected portion can be irradiated with ultra-short waves or microwaves of, for example, about 800 MHz to 2.4 GHz. The ultra-short wave head 1602 is supplied with electric power for generating ultra-short waves by harnesses 210a and 210b. In this figure, the VHF head 1602 and the skin 309 are separated from each other, but the present invention is not limited to this, and the VHF head 1602 and the skin 309 may be in contact with each other.

In FIGS. 15 and 16 described above, the drive pulse generation circuit unit 608f is arranged on the conductor, but the present invention is not limited to this, and the drive pulse generation circuit unit is as in the second embodiment. May be configured to be arranged in the main body or a suction control unit configured separately from the main body. Alternatively, a configuration in which the piezoelectric pump control unit is arranged in the suction control unit may be used. Further, the suction force operating means, the inflow suppressing unit, and the exhaust noise suppressing unit may be arranged.

In FIGS. 15 and 16 above, the exhaust unit 402a and the like are arranged on the conductor, that is, the suction unit is provided on the conductor, but the present invention is not limited to this, and the first aspect is limited to this. As in the embodiment, the exhaust portion 402a may be provided in the main body portion 11 as a suction unit. Alternatively, the exhaust portion 402a may be provided as a suction unit independently of the main body portion 11.

It is difficult for anyone other than the patient to directly confirm the generation state of negative pressure in the cavity 310 of each of the conductors 301a to 301f, the ultrasonic conductor 1501, and the ultrashort wave conductor 1601. For example, if the cup 302 is transparent, it seems that the adsorption state can be judged to some extent by the way the skin rises and the color, but in reality it depends on the position where the conductor is adsorbed, the health condition of the patient, and individual differences. It's not easy. Therefore, a pressure sensor (not shown) may be separately provided to check the degree of adsorption. For example, a pressure sensor may be arranged in the cup 302, a pressure display unit (not shown) for displaying the pressure by the pressure sensor may be arranged in a joint portion or the like, and the degree of adsorption due to negative pressure in the cavity 310 may be confirmed. The pressure display unit may be a meter type display unit, a digital meter, an analog meter, or an indicator that uses a plurality of LEDs to change the number of lights according to the output of the pressure sensor. However, it suffices if the degree of pressure can be confirmed. Alternatively, the pressure display unit is not limited to these meters or the like and may be configured to display only that negative pressure is obtained. For example, an LED that lights up when a pressure sensor detects that negative pressure is obtained. There may be. These pressure display units may be arranged on the guide, or may be arranged on the main body or the suction unit. These pressure indicators make it easy to confirm whether or not the conductor is in close contact with the patient.

Further, the suction force of each conductor may be changed by a separately arranged suction force operation means to obtain the optimum suction force. This configuration is a more desirable configuration because it is possible to avoid the adsorption force being too weak or too strong. In this case, it is better to arrange the pressure display unit and the suction force operation unit as close as possible, the pressure display unit and the suction force operation unit may be arranged on the conductor, and the pressure display unit and the suction force operation unit may be arranged on the suction unit. The operation unit may be arranged, or the pressure display unit and the suction force operation unit may be arranged on the main body 11 or the like.

Alternatively, it is more desirable that the suction force is automatically controlled by feeding back the output from the pressure sensor, not limited to the manual change of the suction force by the suction force operating means. For example, a pressure pump control unit 607d (not shown), which is a pressure pump control unit corresponding to the piezoelectric pump control units 607a to 607c that controls the piezoelectric pump and can input the output of the pressure sensor, is used to output from the pressure sensor. The piezoelectric pump control unit 607d may be configured to automatically control the parameters of the drive pulse so that a desired suction force can be obtained accordingly. Such a configuration is more desirable because not only the guider can properly adhere to the patient but also a good adhesion state can be maintained. Further, the pressure display unit as described above may be used in combination, which is more desirable because the pressure display unit can easily confirm that the conductor is in close contact with the patient by automatically adjusting the pressure. In this configuration, the suction force operating unit may be further arranged to adjust the suction force of the conductor.
