Further, in the lumbar side B direction, that is, in the direction in which urination penetrates and proceeds, as shown in the drawing, a line L1 indicating a small amount, a line L2 indicating a standard amount,
Marks such as a line L3 indicating a large amount and a line L4 indicating a full state are printed.

The resonator 3 is formed in a thin sheet shape, and as shown in FIGS. 4 to 7, a paper having a specific dielectric constant is a film-like insulating sheet 11 made of resin or the like. 8 and a capacitor pattern 13 similarly formed on both sides of the insulating sheet 11 and connected to the coil pattern 12 and provided at the center thereof. By using a detecting device (hereinafter referred to as a detecting device) 20, the amount of water is detected.

That is, the coil pattern 12 of the resonator 3 is A
A thin-film metal such as l, Cu, Au or Ag is formed in a spiral shape to form an inductance component,
Similarly, the capacitor pattern 13 is made of a thin metal.
It is formed in a rectangular shape, and forms a capacitance component by sandwiching both surfaces of the insulating sheet 14. Then, a resonance circuit having a resonance frequency characteristic is formed by an induction component by the coil pattern 12 and a capacitance component by the capacitor patterns 13 and 13, and in a dry state, a transmission radio wave having a frequency corresponding to the resonance frequency as shown in FIG. A reflected radio wave 24b is generated when 23b is present in the place where it is being transmitted. However, when the coil pattern 12 and / or the capacitor pattern 13 is short-circuited by moisture in a wet state instead of a dry state, it does not resonate and does not generate the reflected radio wave 24b.

Here, the resonance frequency f of the resonance circuit is designed by the following equation (1), and the number of turns of the coil pattern 12, the area of the capacitor pattern 13, and the insulating sheet 1
It is uniquely determined by the thickness of 1.

21, a transmission unit 23 connected to the timing signal output unit 22 and provided with a transmission antenna 23a, and a reception unit 24 connected to the timing signal output unit 22 and provided with a reception antenna 24a. A computing unit 25 connected to the transmitting unit 23 and the receiving unit 24;
And an output unit 26 connected to the output unit 21. Then, the transmitting antenna 23a and the receiving antenna 24a are formed on the same plane to form an antenna body.

When the CPU 21 detects moisture, that is, urination, based on the measurement result, the CPU 21 controls a display unit 31 such as a CRT of the notification device 30 and a notification sound generation unit 32 for generating a notification sound to perform display and notification. Notify the caregiver when to change diapers. This notification device 30 is installed in a care staff room or the like.

The operation of the detection device 20 will be described later in detail.

First, in this embodiment, as shown in FIGS. 1 and 3, the resonator 3 is attached to the back surface of a rectangular nonwoven fabric 4 which is sufficiently larger than the area of the resonator 3, and the nonwoven fabric 4 around the resonator 3 is attached. Are attached to the front surface of the dedicated sheet 2 using a pressure-sensitive adhesive layer (or an adhesive tape) provided on the back surface of the sheet 2 in accordance with a line L1...

Here, the nonwoven fabric 4 has a role of absorbing sweat and the like, while a resin laminate is applied to the surface of the resonator 3 on the side of the nonwoven fabric 4, and the resin laminate and the nonwoven fabric 4 are used to form the resonator 3.
Are prevented from getting wet with sweat or the like, and the detection surface of the resonator 3 is limited to the surface on the exclusive sheet 2 side.

The nonwoven fabric 4 and the special sheet 2 used here
Because it is in contact with the human body side, it is good to use a material that does not give a sense of discomfort to the skin. Also, when an adhesive tape is used instead of the nonwoven fabric 4, it is preferable to use a material that does not give a sense of discomfort to the skin as the adhesive tape.

When the diaper is worn on the cared person, first, the cared person's physical condition such as rough skin or a cold should be adjusted to the L1 line indicating a small position, and a large amount of urine must always be applied to the person who has a large amount of urination. Is determined based on the physical condition and water intake amount of the care receiver and the experience value, for example, by adjusting to the line L3 indicating the position of the cared person, using the line L1.
Then, in a state in which the dedicated sheet 2 to which the resonator 3 is attached is placed on the side of the human body of the diaper body 1, the user attaches the reference line L0 marked on the dedicated sheet 2 to exactly match the position of the urinary organ of the care receiver. It is good. Of course, the resonator 3 may be provided on the reference line L0 in some cases.

In the present embodiment, the pad-type diaper body 1 that is housed in the diaper cover and forms a diaper is used. However, the pad-type diaper body 1 that forms a pants-type diaper may of course be used. Also, although the dedicated sheet 2 is used, the above-mentioned lines L0 are directly printed on the diaper body 1, and the resonator 3 is directly formed using the pressure-sensitive adhesive layer of the nonwoven fabric 4 or the adhesive tape as shown in FIG. You may make it stick on the diaper body 1.

Next, the operation of the detection device 20 will be described with reference to FIGS. The resonator 3 is configured to resonate at a predetermined resonance frequency, and is mounted on the diaper body 1 used for the diaper cover 1a mounted on the care receiver via the dedicated sheet 2 as described above. Shall be.

Transmission antenna 23 formed on the same plane
and a receiving antenna 24a is placed on a bed 5 on which a care receiver wearing a diaper cover 1a is lying down as shown in FIG. Radio noise of a frequency exists in the field. Now, in the detection device 20, the transmission radio wave 23b having the resonance frequency corresponding to the resonance frequency of the resonator 3 is set.
Occurs. Then, the transmission antenna 23a transmits the transmission radio wave 23b of the resonance frequency excluding a certain frequency of the radio noise to a place formed by the bed 5.

Here, the design of the resonator 3 is designed such that the transmitted radio wave 23b corresponds to the fluctuation of the resonance frequency caused by the manufacturing fluctuation and the shape change of the resonator 3.
Before and after the resonance frequency of (1), the frequency is changed not by continuously changing (analog type) but by discrete values. For example, if the frequency is 5M
In the case of the Hz band, ... 4.97 MHz, 4.98 MHz,
4.99MHz, 5.00MHz, 5.01MHz, 50
Variable at 0.01 MHz intervals, such as 2 MHz.

Then, the transmitting section 23 operates based on the timing signal shown in FIG. 10A output from the timing signal output section 22, and is defined by each spot as shown in FIG. 10B. The above-mentioned transmission radio waves 23b shown in FIG. 10D are sequentially emitted from the transmission antenna 23a to the field.

When the resonator 3 is in a place where the transmission radio wave 23b is being transmitted and is in a dry state, after the transmission of the transmission radio wave 23b is stopped, the resonator 3 has a duration of P2 compared to the duration P1 of the transmission radio wave 23b. Generates a long reflected radio wave 24b,
A residual radio wave S shown in FIG. 10F is formed. On the other hand, in a wet state in which the coil pattern 12 or the capacitor pattern 13 is short-circuited by moisture instead of a dry state, the reflected radio wave 24b, that is, the residual radio wave S is not generated.

Next, as shown in FIG. 10 (c), the detecting device 20 receiving section 24 performs a receiving operation based on the timing signal, receives a received radio wave including a reflected radio wave, and
After stopping the transmission radio wave 23b from the computer, the computing unit 25 measures the reception intensity of the residual radio wave S (duration P2) in a dry state of the resonator 3 based on the reception radio wave, and
Give to U21. On the other hand, in the wet state of the resonator 3, FIG.
No residual radio wave S is received as shown in FIG.

Next, the CPU 21 detects the presence or absence of moisture in the diaper cover 1a based on the received radio wave characteristics of the residual radio wave S given from the arithmetic unit 25. That is, if the reception intensity of the residual radio wave S for each spot is equal to or higher than a predetermined value, and if the reception intensity is compared with the characteristic for each spot stored in advance and is within a certain allowable value, the residual radio wave S is detected. to decide. Then, it is determined that the resonator 3 is present in the field and is in a dry state without any abnormality, and does not output the moisture detection information to the output unit 26. When the intensity characteristic is equal to or less than the predetermined value and the residual radio wave S is not detected, it is determined that the resonator 3 does not exist in the field, or that moisture adheres to and penetrates the resonator 3 to form no resonance circuit. . Further, when the resonator 3 is installed so as to be always present in the field, the CPU 21 determines that the moisture in the diaper body 1 has been detected when the undetected state of the residual radio wave S continues for a certain period of time, ie, It is determined that the care receiver wearing the diaper cover has urinated a predetermined amount of urine, and outputs the moisture detection information to the notification device 30 via the output unit 26.

Based on the stored personal information, the notification device 30 displays on the display unit 31 that the amount of urination has reached a predetermined amount and that it is time to replace the diaper, and a notification sound from the notification sound generation unit 32. And notify the caregiver.

In the present embodiment, a diaper changing time sensor can be provided which can detect the time of the diaper suitable for the cared person in consideration of the physical condition and the amount of urination of the cared person. This eliminates the need for replacement or checking, and can maintain a hygienic condition while reducing the burden on the caregiver and preventing troubled sleep for the cared person. After use, the resonator 3 is replaced with the diaper 1

Next, as shown in FIG. 10C, in the detecting device 20, the receiving unit 24 performs a receiving operation based on the timing signal, receives the received radio wave including the reflected radio wave 24b, and transmits the signal from the transmitting unit 23. After stopping the radio wave 23b, the arithmetic unit 2
5 measures the reception intensity of the residual radio wave S (duration P2) while the resonators 3a are in a dry state based on the received radio wave, and gives the measurement result to the CPU 21. On the other hand, in the wet state of the resonators 3a, no reflected radio wave 24b is generated, and no residual radio wave S is received as shown in FIG.

Further, the CPU 21 detects the presence or absence of moisture in the diaper 1 based on the received radio wave characteristic of the residual radio wave S given from the arithmetic unit 25. That is, if the reception intensity of the residual radio wave S for each spot is equal to or higher than a predetermined value and the reception intensity is compared with the characteristic of each spot stored in the selected CH in advance and is within a certain allowable value, the residual radio wave S S
Is determined to be detected. .. Are present in the field and are in a dry state without any abnormality, and do not output the moisture detection information to the output unit 26. When the intensity characteristic is equal to or less than the predetermined value and the residual radio wave S is not detected, it is determined that the moisture does not adhere to and penetrate the resonators 3a to form a resonance circuit.

Here, the detecting device 20 can select and set the resonator at the position corresponding to the urination amount to be detected in advance according to the care receiver to be detected, and transmits the CH to the selected and set resonator. If the undetected state of the residual radio wave S continues for a certain period of time when transmitting the radio wave, the CPU
Reference numeral 21 determines that moisture in the diaper 1 has been detected, and outputs moisture detection information to the notification device 30 via the output unit 26.
Thereby, the care giver can know that the diaper body 1 worn by the care receiver has reached the replacement time by displaying or notifying the notification device 30.

Also in the present embodiment, a diaper changing time sensor capable of detecting the diaper changing time suitable for the cared person can be provided in consideration of the physical condition and urination volume of the cared person. The necessity of changing diapers and checking is eliminated, and a hygienic condition can be ensured while reducing the burden on the caregiver and preventing the care receiver from disturbing sleep. After use, the resonators 3a are separated from the diaper body 1 so that they can be easily separated at the time of disposal.

The diaper body 1 according to the second to fifth embodiments.
In the drawings, the symbols "A" and "B" are attached to the abdomen and the waist, respectively, as in the first embodiment. Further, when the diaper 1 is for a man to be wound around a urination organ, the reference position is set to the longitudinal center position of the diaper 1 as described in the first embodiment. (Embodiment 6) In Embodiment 1 described above, a dedicated sheet 2 made of a nonwoven fabric is laid on the surface of the diaper body 1, a resonator 3 is provided on the front side of the dedicated sheet 2, and a nonwoven fabric 4 having a pressure-sensitive adhesive layer formed on the back surface. In such a configuration, the exclusive sheet 2 is a liquid permeable sheet 1b of an inner layer that is in contact with the human body of the diaper body 1.
When it is away from the side, the urine retained in the internal liquid substance absorber 1c does not pass through the dedicated sheet 2, and therefore, the resonator 3
There is a fear that moisture detection by the method cannot be performed.

Therefore, the diaper changing sensor according to the present embodiment has a moisture retaining member 60 interposed between the resonator 3 and the dedicated sheet 2 as shown in FIG. A configuration was adopted in which the resonator 3 was attached with a nonwoven fabric 4 (or an adhesive tape) having an adhesive layer formed thereon. In this case, as shown in FIG. 23, a projection 61 projecting from the back surface of the moisture retaining body 60 penetrates through the liquid permeable sheet 1b of the diaper body 1 and bites into the internal liquid absorbent body 1c, so that the exclusive sheet 2 becomes diaper. Prevents leaving body 1.

Therefore, in the diaper changing sensor according to the present embodiment, the urine retained in the liquid absorbent 1c can be surely diffused by passing through the exclusive sheet 2 as a nonwoven fabric.
The resonator 3 can detect the urine diffused along the dedicated sheet 2 via the moisture holder 60.

The protrusion 3 is attached to the outermost layer of the diaper 1 on the side of the non-liquid permeable sheet 1a via the moisture retainer 60, and the projection 61 and the moisture retainer that are cut into the internal liquid absorber 1c. The urine from inside the diaper body 1 that travels through 60 may be brought into contact with the resonator 3.

(Embodiment 7) In the diaper changing time sensors of the above-described Embodiments 1 to 6, when the pattern of the resonator 3 is short-circuited with urine, a radio wave having a frequency corresponding to the resonance frequency of the resonator 3 is transmitted. Utilizing the fact that the reflected radio wave 24b is no longer generated, the method is used for detecting a urination amount corresponding to the mounting position of the resonator 3 where the reflected radio wave 24b is no longer generated. . However, even if the sensor is damaged when the diaper is replaced, or if the user forgets to attach the diaper, the reflected radio wave 24b is not generated.
This is erroneously detected as urination.

In this embodiment, a diaper replacement time sensor that detects moisture by detecting that the reflected radio wave 24b is generated and the reception intensity of the residual radio wave S becomes a predetermined value or more is realized. Embodiments are shown in FIGS.
As shown in FIG.
The formation portions of 3 and 13 are formed by the moisture absorber 62.

When the diaper replacement sensor according to the present embodiment is used, in a place where the attached diaper body 1 is present, the water absorber 62 sufficiently absorbs urine and the amount of urine absorbed is predetermined. The radio wave of the frequency corresponding to the resonance frequency determined by the capacity when the amount of
When the reception intensity of the residual radio wave S exceeds a predetermined value due to the occurrence of 4b, it is detected that a predetermined amount of urination has occurred.

Detecting device 2 used in accordance with this embodiment
As 0, a device having a hardware configuration shown in FIG. 8 may be used. However, the CPU 21 determines whether or not the water absorber 62 has sufficiently absorbed the urine and the amount of the absorbed urine reaches a predetermined amount. The transmitting unit 23 transmits a radio wave of a frequency corresponding to the resonance frequency to a place where the diaper body 1 equipped with the diaper changing sensor is present.
And the reflected radio wave 24 corresponding to the resonance frequency.
When the reception strength of the residual radio wave S including b becomes equal to or more than a predetermined value,
It is determined that there is a predetermined amount of urination.

By using the diaper changing time sensor according to the present embodiment having the above-described configuration, when the sensor is damaged or the user forgets to attach the diaper, erroneous detection of urination is not performed, and as a result, wasteful diaper changing work is eliminated. be able to.

(Embodiment 8) In the above embodiments 1 to 7, the sensor configuration has a configuration in which the resonator 3 is directly wetted by urine. However, the diaper replacement sensor according to this embodiment can be reused without getting wet with urine. The configuration is such that the coil pattern 12 formed on the insulating sheet 11 in the same manner as the coil pattern 12 of the resonator 3 of the first embodiment as shown in FIG. A pair of capacitor patterns 13 formed in parallel
The resonator 3 composed of a and 13b is used. In this resonator 3, the capacitance value between the capacitor patterns 13 a and 13 b is determined by the amount of water in the pattern, so that the surface of the insulating sheet 11 is parallel to the surface of the diaper 1. Is attached to the diaper body 1, the capacitor pattern 1 can be adjusted according to the progress of urination.
3a and 13b change, the change causes the inductive component of the coil pattern 12 and the capacitor pattern 1 to change.
The resonance frequency determined by the capacitance component between 3a and 13b changes. Therefore, it is not necessary to attach the resonator 3 to the diaper 1 so as to be wet directly.

In order to use the diaper changing sensor according to the present embodiment, as shown in FIG. 27, the resonator 3 is attached to the surface of the non-liquid permeable sheet 1a which is the outermost layer of the diaper 1 by using an adhesive tape. When the diaper body 1 is wetted by urination, the resonator 3
Can be reused because it does not get wet.

When the resonator 3 is attached to the diaper 1, the position of the coil pattern 12 is made to substantially correspond to the urination reference position, and the extension direction of the capacitor patterns 13a and 13b is set as the urination progress direction.

Here, similar to the seventh embodiment, the detecting device 20 used in correspondence with the diaper changing sensor according to the present embodiment is a single unit that generates a reflected radio wave 24b at a resonance frequency corresponding to a predetermined urination volume, for example. When a radio wave of one frequency is transmitted to the place where the diaper body 1 equipped with the diaper replacement sensor is present, and the remaining radio wave S including the reflected radio wave 24b from the place is received and its reception intensity becomes a predetermined value or more, A device equipped with a function of detecting the presence of a predetermined urination volume, or a radio wave to be transmitted while sweeping the frequency of a transmission radio wave so as to correspond to a resonance frequency from 0% to 100% of urination volume Reflected wave 24b corresponding to the frequency of
By monitoring the presence or absence of the residual radio wave S including, the change in the amount of urination is captured, and the amount of urination is displayed in an analog manner by the number of light emitting diodes and a bar graph display by a liquid crystal display,
A device having a function of notifying when a reflected radio wave corresponding to a resonance frequency equal to or higher than a predetermined urination amount is received is used.

Note that, as shown in FIG.
Is provided with a tap t so that the capacitor patterns 13a, 13
If the connection position of the coil pattern 12 with respect to b can be changed, the frequency of the radio wave transmitted to the field can be changed.

Wear. The notification device of the detection unit 40 is provided by a sound or an indicator.
It is configured with a display function.

If the antenna unit AT is embedded in an apron or nursing clothes worn by the caregiver and the detection unit 40 is hung on the waist of the nurse, the caregiver approaches the care receiver lying on the bed. The diaper replacement time can be detected without being noticed by the care receiver alone, and the care receiver does not feel uncomfortable.

As shown in FIG. 31 (a), the antenna AT is formed so as to be foldable into two pieces, one piece AT1 is formed integrally with the detection unit 40, and the other piece AT2 is formed as 18 pieces.
It may be possible to develop 0 °. In this case, by improving the portability by folding the antenna body AT and expanding it,
The surface of the antenna body AT is enlarged to improve the antenna efficiency. Also, as shown in FIG.
Alternatively, the other piece AT2 may be developed at a right angle, and the transmitting and receiving antennas incorporated in each piece AT1 and AT2 may be alternately switched to switch the transmitting and receiving direction between the vertical direction and the horizontal direction. Also, as shown in FIG. 31 (c), the antenna body AT is connected to a center piece AT10 and both ends of a piece AT10.

The moisture detecting method used in the detecting unit 40 of the present embodiment is a method of detecting the moisture based on the received radio wave characteristic as the received intensity of the residual radio wave S,
In addition, a detection method suitable for the resonator of the diaper replacement time sensor to be used, such as a method of detecting the received radio wave characteristic as a change in the intensity of the reflected radio wave 24b and detecting moisture based on the change in the intensity, may be employed. (Embodiment 10) The detecting device 20 or the detecting unit 40 used in any of Embodiments 1 to 8 is also a diaper body 1.
Although only the urination detection by the resonator 3 disposed in the above is performed, the care receiver goes to the tray in the device in which the antenna body including the transmission antenna 23a and the reception antenna 24a is fixedly arranged on the bed 5 as shown in FIG. When the user leaves the floor or walks away from the floor, the residual radio wave S generated by the resonator 3 disappears, and thus these are determined to be urination detection.

On the other hand, there is a problem in that if the caregiver judges that the diaper change is not necessary even if the detection notification is issued and the ward is not rushed to the bedroom or the sickroom, the care receiver cannot prevent the care recipient from going out without permission. . In addition, there is a problem that the discovery is delayed even in the case of a failure. In addition, the nursing staff detects
To the bed 5 and perform urination detection,
Of course, it could not be detected separately from leaving the care receiver.

In the present embodiment, the transmission antenna 23a and the reception antenna are used as shown in FIG. 32 as in FIG. The antenna body composed of the antenna 24a is attached to the bed 5, and the detection device 20 is fixedly arranged. On the other hand, for the cared person M lying on the bed 5, in addition to the resonator 3 arranged on the diaper body 1 side, the chest A resonator 3 ′ having a resonance frequency different from the resonance frequency of the resonator 3 (constructively the same as the resonator 3 of the first embodiment) is attached to a portion above the waist such as a pocket or underwear. 23a, a transmission radio wave 23b having a resonance frequency corresponding to each of the resonators 3 and 3 'is sequentially generated, and the care receiver M in which the detection range α where the transmission radio wave 23b is transmitted is lying down. The height is set so that it can be wrapped around.

Here, the detection device 20 monitors the presence or absence of the residual radio wave S by the resonator 3 ′ together with the monitoring of the presence or absence of the residual radio wave S by the resonator 3 on the diaper 1 side.
At the same time as detecting the urination on the side, the leaving of the care-receiver M or sweating is detected, and the detection results are reported and displayed by the reporting device 30.

When the monitoring by the resonator 3 ′ is performed only for leaving the floor, the resonator 3 ′ is completely waterproofed so as not to be affected by perspiration.

In this case, when the care receiver M rises, the resonator 3 'on the chest moves out of the detection range, and the radio wave 24b reflected by the resonator 3', that is, the residual radio wave S is no longer received. The detection device 20 can detect that M has left or is about to leave.

The caregiver notifies the presence / absence of urination detection by the resonator 3 and the presence / absence detection of leaving the bed by the resonator 3 '.
The following judgment can be made by knowing the information display.

That is, when there is no detection by both of the resonators 3 and 3 ', it can be determined that the care receiver M is sleeping. Although there is no detection of leaving the bed by the resonator 3 ′,
If there is urination detection by the user, the care receiver M can urinate, and it can be determined that the diaper needs to be replaced. Furthermore, if there is no urination detection by the resonator 3 and there is detection of leaving the bed by the resonator 3 ', it indicates that the care receiver M has left the bed, is getting up, or has a failure. M
Is determined to be necessary, and the caregiver immediately rushes to the bedroom or the sickroom to prevent the care recipient M from going out on his or her own initiative or to discover a failure of the device.

[0104] Also, if the care receiver is in a physical condition with night sweats,
If it is desired to know when to change the underwear, a non-waterproof resonator 3 'is attached.

In this case, the residual radio wave S generated by the resonator 3 '
The condition under which the resonator 3 ′ disappears includes the case where the resonator 3 ′ is wetted by sweat in addition to leaving the care-receiver M or causing a failure as described above. In any case, if there is a detection report indicating that the residual radio wave S has disappeared due to the resonator 3 ', the caregiver can judge that it is necessary to check the state of the care receiver M, and the bedroom is similar to the above case. Alternatively, the caregiver can immediately rush to the sickroom to prevent the care recipient from going out on his or her own, or to find out if the device is out of order. Etc. can be prevented beforehand.

The diaper changing time sensor constituted by the diaper 1, the resonator 3 and the like according to this embodiment may use any of the above-described first to eighth embodiments. Also, the mounting position of the resonator 3 'is not limited to the chest,
At least a body part that comes out of the detection range α when the upper body is raised from the lying state, for example, an arm may be used.

(Embodiment 11) The present embodiment relates to a diaper replacement time sensor corresponding to bed exit detection. The diaper replacement time sensor according to the present embodiment employs a tag sheet 70 as shown in FIG. The resonators 31 are sequentially adhered to positions corresponding to a predetermined amount of urination from the reference position, and the tag sheet 70 is attached to the non-liquid permeable sheet 1a which is the outermost layer of the diaper 1 as shown in FIG. It can be attached to the surface and made reusable. Among the resonators 31 used here, the resonator 31 has the same configuration as the resonator 3 of the first embodiment, and the other resonators 32.
As shown in FIG. 8, the resonator 3 shown in Embodiment 8 is downsized, and the electrodes 13a of the respective capacitor patterns are used.
13b is set to a direction orthogonal to the urination progressing direction (longitudinal direction of the diaper 1), and each of the resonators 32 is set to have a predetermined resonance frequency f2 when urination is located between the electrodes. .. Are different from each other. The resonance frequency of the resonator 31 is f1 different from these resonance frequencies f2. Here, the resonator 31 has a predetermined capacity because the direction in which the electrodes of the capacitor pattern 13 on both sides face each other is a direction orthogonal to the surface of the diaper body 1 and is not directly wet even if urine is discharged. Therefore, when a radio wave corresponding to the resonance frequency f1 is transmitted, a reflected radio wave is generated. The other resonators 32 are the capacitor patterns 13a,
When the urination proceeds while filling between the capacitor patterns 13a and 13b, a predetermined resonance frequency f2... Is used.
To have.

In the case of using the diaper changing sensor according to the present embodiment, the inspection device 20 sets each of the resonators 31 in a place where the diaper body 1 having the diaper changing sensor is present.
, Including the reflected radio wave 24b when transmitting a radio wave having a frequency corresponding to the resonance frequency f1 of the diaper 1 in the field where the diaper 1 is present and transmitting a radio wave having a frequency corresponding to the resonance frequency f1 of the reference resonator 31. Based on the presence or absence of the residual radio wave S, it is possible to detect that the person wearing the diaper 1 does not leave the floor and is present in a predetermined place, and that a frequency corresponding to the resonance frequency f2 of the other resonators 32. Based on the presence or absence of the reflected radio wave 24b (residual radio wave S) when the radio wave is transmitted, it is possible to detect whether the urination amount is small, standard, or large. (Embodiment 12) In the present embodiment, when the portable detection unit 40 of Embodiment 9 is used, at which position of the diaper body 1 worn by the care receiver M the diaper replacement time sensor is mounted. Is added to make it possible to easily detect.

In other words, when the portable detection unit 40 shown in the ninth embodiment is used, the position of the diaper time sensor on the diaper body 1 cannot be determined from the outside of the diaper cover or the clothing. You cannot point to the right place. Therefore, the checking work took a long time.

Therefore, as shown in FIG. 35, a position (b) near the position (a) where the moisture detecting resonator 3 is attached is waterproofed so as not to be wet by urine, and is different from the resonator 3. When the caregiver checks the diaper of the care receiver, the detection unit 40 first receives the radio wave of the frequency corresponding to the resonance frequency of the resonator 3 '' when the caregiver checks the diaper of the care receiver. To the diaper position of the person,
A position where the reflected radio wave 24b can be received is searched. That is,
Since the resonator 3 ″ does not short-circuit even when urinating occurs and always generates a reflected radio wave 24b, if the position of the resonator 3 ″ is known, the position of the resonator 3 for moisture detection can be known. . Then, when the position is known, if a radio wave of a frequency corresponding to the resonance frequency of the resonator 3 is transmitted from the detection unit 40 to the position of the water detecting resonator 3, that is, the position where the diaper replacement time sensor is stuck, It is possible to detect the time of replacement of the diaper body 1 worn by the caregiver. As a result, the work time of the diaper check by the caregiver can be reduced.

If the resonator 3 ″ is attached to the front position (c) or the rear position (d) of the surface of the outermost layer of the non-liquid permeable sheet 1 a of the diaper 1, the floor is left as shown in FIG. Then, the diaper check of the care receiver M during the activity can be performed well.

Further, the resonator 3 for moisture detection and the resonator 3 ″ for position detection are attached to the same adhesive tape 80 as shown in FIG. Or a diaper body using a pressure-sensitive adhesive applied to the non-woven fabric 4 with an adhesive tape or the non-woven fabric 4 with the two resonators 3 and 3 ″ attached to the non-woven fabric 4 serving as a base material in advance. If it is made to stick to 1, the labor of the sticking work can be reduced. (Embodiment 13) Although the detection unit 40 of Embodiment 6 is configured to be easily carried by a caregiver,
In addition to the portable configuration, the detection unit 40 of the present embodiment collects information including the presence / absence of urination detection of each of a plurality of target care receivers for each care receiver each time the caregiver checks. In order to facilitate the management of care receivers, including changing diapers, by adding the function of displaying the history of past checks at the time of operation at the time of checking. It was done.

It is composed of a nonvolatile and rewritable memory such as OM.

The CPU 50 can switch the operation mode according to the operation of the operation display section 41 and the reset switch RS. When the reset switch RS is operated, the data stored in the storage section 57 is initialized. And a registration screen (not shown) for registering the name of the care receiver assigned to each of the operation units 451 to 454, and the storage area previously allocated to the storage unit 57 in association with the operation units 451 to 454.

I can do it.

Next, the actual use using the detection unit 40 of the present embodiment will be described below.

First, as the diaper changing time sensor to be worn on each cared person, one in which the resonators 3a are arranged in advance at a plurality of positions described in the fifth embodiment is used. It is assumed that the relationship between the resonance frequency of 3a ... and the arrangement position is registered in advance. Then, on the caregiver side, the resonator at the position corresponding to the urination amount which was at the time of each diaper replacement is registered in advance for each cared person, for example, before patrol at night.

The registration screen is displayed on the operation unit 451 as described above.
It is assumed that the display can be performed according to the operation patterns and operation procedures of ４５ to 454.

After the data corresponding to the amount of urination of each cared person is registered in this way, a cyclic check is performed. This check is determined, for example, every three hours, and is performed periodically.

The care giver wears the detection unit 40, holds the antenna body AT by hand or attaches it to a nursing suit, and goes around the bedroom or the sick room of the care receiver to make a check. In the case of checking “Mr. △△” corresponding to 451, if the user touches the operation section 451 with the antenna body AT hung on the side of Mr. △△ who is the care receiver, the CPU 50 responds to this operation. CH (channel) -1 corresponding to the resonance frequency of each resonator 3a ...
The transmission unit 5 transmits transmission radio waves having different resonance frequencies
2 in the same manner as in the fifth embodiment, and the timing output unit 51 appropriately selects and sequentially switches the oscillation frequency from CH-1. The bed 5 on which the cared person is lying
Send to the place above.

When the transmission radio wave corresponding to the resonance frequency of each of the resonators 3a is transmitted as described above, the transmission radio wave is present in the place where the transmission radio wave is being transmitted, and the transmission radio wave is transmitted in the dry state of the resonator 3a. After the transmission is stopped, a reflected radio wave having a longer duration than that of the transmission radio wave is generated in the same manner as described above, and a residual radio wave S is formed. On the other hand, the resonators 3a... In which the coil pattern 12 or the capacitor pattern 13 is short-circuited by moisture but not in a dry state do not generate a reflected radio wave, that is, a residual radio wave S.

Therefore, there are a resonator that generates the remaining electric wave S and a resonator that does not generate the remaining radio wave S according to the amount of urination of the cared person.

After the receiving unit 53 of the detecting unit 40 performs a receiving operation of receiving the received radio wave including the reflected radio wave based on the timing signal, and stops the transmission radio wave from the transmitting unit 52, the calculating unit 54 converts the received radio wave to the received radio wave. Based on each resonator 3a
., And the measurement result is given to the CPU 50.

The CPU 50 operates in the same manner as in the fifth embodiment.
The presence / absence of moisture in the diaper 1 is detected based on the received radio wave characteristics of the residual radio wave S given from the diaper 1.

The following display is made based on the detection result.
Notification and history storage processing are performed.

That is, the detected result is displayed in the leftmost column of the information display section 48 shown in FIG. For example, when it is detected that the resonator corresponding to a large amount of urination does not generate the residual radio wave S, the character of "many" is displayed.
Similarly, for small quantities, "small", for standard quantities,
Displays the character of "mark". At the same time, "hour" of the current time is displayed in the leftmost column of the information display section 47. In the illustrated example, "7"
"7" of "hour" will be displayed.

The CPU 50 stores the above detection result and time data in the storage area of the storage unit 57 assigned to the operation unit 451.

The CPU 50 reads the past two detection results and detection times from the history information stored in the storage area corresponding to the operation unit 451 of the storage unit 57 by this check operation. The detection result at the time of the previous check and its detection time are displayed in the center column of 47, and the detection result at the time of the previous check and its detection time are displayed in the rightmost column. In the figure, the symbol x indicates that urination was not detected.

Here, information on the amount of urination is obtained from the history data of the check results, and the date and time of diaper replacement and the number of replacements based on the diaper replacement information are obtained from the diaper replacement information.

For example, 1) Mr. 排 urinates approximately every three hours. (Urine volume, standard) 2) Mr. XX urinates every 30 minutes after eating. (Urination volume, large amount) 3) Mr. ○ △ urinates one hour after drinking the drink. (Food and drinks are taken on a regular basis. Of course, if the caregiver records it in a care diary, it can be compared with history data and diaper replacement information.) From the combination, for example, Mr. △△ having a urination pattern every three hours that urinates at 1:00 pm can be predicted to urinate at 4:00 pm.

Further, since the average value of the number of diaper changes per day can be known from one-month data, for example, when the number of diaper changes is extremely increased or decreased, or when the number of diaper changes is 2-3
In the case of consecutive days, it can be inferred that the physical condition of the cared person has gone wrong.
