And has a terminal monitoring device 90 to present information to relevant personnel.

Figure 1 is only one of the embodiments of the present invention, and the actual application is not limited to this. For example, the gateway can receive the vital sign data transmitted by several vital sign monitoring systems at the same time. In addition, the gateway The Dao device may have a pairing system that can integrate the data of the vital sign monitoring system of several beds into a display screen that medical staff can easily grasp and understand to achieve the effect of multi-bed monitoring and improve the efficiency of medical monitoring. For example, it can be used for individual monitoring of multiple beds, or monitoring of multiple vital sign sensing components for one bed.

The monitoring terminal device 90 can be a display device, such as a computer, a laptop, a tablet, a mobile phone, etc., but is not limited to this, which is convenient for medical staff to perform monitoring.

Taking a medical needle as an example, as shown in Figure 2, during infusion or dialysis, the needle 20 is generally pierced inside the arm 10, thereby forming a contact area 11 between the needle and the skin. The range of the contact area is not limited to the second figure. In actual use, it can be based on different technical needs, as well as medical devices and skin. The contact method is enlarged or reduced. Surrounding the contact area 11 is the vital sign sensing component 30 according to the embodiment of the present invention.

As shown in Figure 3, the vital signs sensing component 30 according to an embodiment of the present invention, located near the contact area 11, may include a substrate 31 and an on-skin sensor; wherein, the substrate 31 has a surrounding Portion 311 and a connecting portion 33. The surrounding portion 311 is used to surround and expose the contact area 11 between the medical device and the skin; the leakage detection circuit 32 is placed on the upper surface of the substrate 31 and includes at least the first An electrode lead 321, a second electrode lead 322, and a third electrode lead 323. The first, second, and third electrode leads are separated by a certain distance and approach a short circuit when they are bridged by liquid.

The monitoring system 70 includes a warning module 71 and a signal transmission module 72. The warning module 71 is electrically connected to different electrode wires on the substrate 31 through the connection portion 33 of the substrate 31, or through one of them. The wire extension part is electrically connected to the different electrode wires, and generates a warning signal according to the short-circuit conduction condition between the different electrode wires. The above-mentioned warning signal may directly send an audible alarm on the monitoring system 70 through an audible alarm element; or be further transmitted by the signal transmission module 72 to the terminal device 90, and an alarm may be issued on the terminal device 90.

Wherein, the surrounding portion 311 is provided with an opening 40, two end portions of the surrounding portion 311 respectively extend toward the opening with two extension blocks 31a, 31b, the extension blocks 31a, 31b are used to increase local leakage The detection area reduces the detection dead angle.

According to the embodiment of the present invention, the extension blocks 31a, 31b are rectangular, but they can also be semicircular, etc., which are not limited thereto. The length of the side of the extension block adjacent to the opening is greater than 2 mm, and the length of the side adjacent to the inner side of the surrounding portion 311 is greater than 1 mm.

Wherein, the vital sign data detected by the vital sign sensing component is transmitted through the signal transmission module 72. The signal transmission module 72 may be a wired transmission module or a wireless transmission module. The transmission module, the wireless transmission module can be Zigbee, Bluetooth, Wi-Fi, etc., but is not limited to this. Wired transmission has the function of stable transmission, while wireless transmission can provide sufficient mobility between devices, but may also be limited by the interference of the external environment and the transmission function is not good. You can make appropriate adjustments according to the environment and resources. .

Figure 3 is only one of the embodiments of the present invention, and the actual application is not limited to this. For example, the monitoring system 70 can supply power to the leakage detection circuit 32, and it can be based on whether different electrode wires are short-circuited or open-circuited, and The combination of short-circuited or open-circuited electrode leads triggers different warning levels, but the combination of the monitoring system 70, the substrate 31 and the leakage detection circuit 32 can be integrated through the connection part 33 of the substrate 31, or it can be a separate body. When connected separately, the substrate 31 and the leakage detection circuit 32 can separately form a vital sign sensing component 30, which can be sold separately, and then combined with the monitoring system 70, it can be used in clinics. In this way, even after the substrate 31 is contaminated, the monitoring system 70 can still be reused, saving overall cost.

Specifically, as shown in Figure 3, in the leakage detection circuit 32, the first electrode lead 321 is spaced apart from the second and third electrode leads, and is connected to the second and third electrode leads when bridged by liquid. / Or the third electrode lead is close to a short circuit; and the warning module 71 is electrically connected to the first electrode lead 321, the second electrode lead 322, and the third electrode lead 323, when the first electrode lead 321 and When the second electrode wire 322 and/or the third electrode wire 323 are short-circuited, an alarm is triggered. Since the distance and position between different electrode wires are foreseen, the amount of leakage and the spread area can be sensed according to the short circuit between different electrode wires, for example, the first electrode wire 321 and the second electrode wire 322 are short-circuited. When the second electrode lead 322 and the third electrode lead 323 are short-circuited, the second alarm is triggered. Since the third electrode lead 323 is located closer to the outer edge, it indicates a higher degree of leakage and a spreading area. Increase, therefore, the level of the second-level alert is higher than the level of the first-level alert.

The distribution of the first electrode lead 321, the second electrode lead 322, and the third electrode lead 323 is not limited to Fig. 3, and may be other distribution forms. For example, as shown in Fig. 4, it is another type of different electrode lead. Distribution form, the second electrode lead 322 and the third electrode lead 323 are at the same distance from the first electrode lead 321, but the positions are opposite, so that when the first electrode lead 321 and the second electrode lead 322 or the third electrode lead 323 are short-circuited , The first level warning is triggered, and when the first electrode lead 321, the second electrode lead 322, and the third electrode lead 323 are short-circuited, the second level warning is triggered. The more short-circuit points, the larger the leakage area, and therefore the higher the warning level.

According to another embodiment of the present invention, in addition to the first, second, and third electrode wires described in FIG. 3, it may further include a fourth electrode wire 324 and a fifth electrode wire 325 (middle electrode wire), such as As shown in Figure 5. The different electrode wires are separated by a certain distance and approach short circuit when they are crossed by liquid; and the warning module 71 is electrically connected to the first electrode wire 321, when the first electrode wire 321 and /Or when the second electrode lead 322, the third electrode lead 323, the fourth electrode lead 324, and the fifth electrode lead 325 are short-circuited, an alarm is triggered. Since the distance and position between the different electrode wires are predicted, the amount of leakage and the spread area can be sensed according to the short circuit between the different electrode wires, such as the first electrode wire 321 and the fourth electrode wire 324 or When the fifth electrode wire 325 is short-circuited, the first-level warning is triggered, and when the first electrode wire 321 and the third electrode wire 323 or the second electrode wire 322 are short-circuited, the third-level warning is triggered; because the second electrode wire 322 and the third electrode wire The position of 323 is closer to the outer edge, which means that the degree of leakage is higher and the area of spreading is increased. Therefore, the warning level is also higher.

Wherein, the distance between the electrode wires is greater than 0.05 mm.

When there are more different electrode wires distributed in the leakage detection circuit, the more detection areas can be formed, the more accurate the detection of the amount of leakage, and the warning level can be adjusted accordingly.

In order to further increase the sensitivity of detection, on the one hand, it is possible to reduce the distance between each electrode wire On the other hand, the specific shape of the electrode wires can be designed to increase the density of the electrode wires. For example, at least one interlaced sensing area can be designed between different electrode wires of the leakage detection circuit. In the interwoven sensing area, the different electrode wires form closely adjacent interlaced shapes.

As shown in Figure 6, at least one interlaced sensing area 326 is provided between different electrode wires 321 and 322. It is preferable to evenly distribute a plurality of interlaced sensing areas according to the surrounding form. In the interlaced sensing area 326 , The different electrode wires form closely adjacent interlaced shapes. When the leakage flows through the first electrode wire 321 but has not yet flowed to the third electrode wire 322, if there is no interwoven sensing area 326, the short circuit warning will not be triggered, but if it happens to flow through the interwoven sensing area 326, A short-circuit warning will occur immediately. If the number of interlaced sensing regions is further increased, the sensitivity can be further enhanced.

When the leakage detection circuit 32 includes a plurality of intermediate electrode wires in addition to the first electrode wire 321, the second electrode wire 322, and the third electrode wire 323, the interweaving sensing area is designed between the two electrode wires. Multi-point detection between different electrode wires can be formed. The warning module 71 can sense the amount of leakage and the area of the leakage according to the number and/or position of the electrode wires that are short-circuited and can trigger different warnings. level.

For example, as shown in FIG. 7, at least one interlaced sensing area 326 is designed between the first electrode wire 321 and the remaining electrode wires. In the interlaced sensing area 326, the different electrode wires form a tight phase. Pro's staggered shape. In this way, since the remaining electrode wires and the first electrode wires 321 have a distance and position correspondence, the warning module triggers different warning levels according to the position and/or number of the electrode wires that are short-circuited.

When the substrate is made of permeable materials, it can accelerate the absorption of leakage, and permeable materials such as gauze and cotton pads are medical products with high acceptance by nursing staff, and nursing staff will need to use gauze when assisting patients in hemodialysis. The combined application of metal knitting technology enables the gauze itself to detect needle-off and blood leakage, which will improve the quality of medical care and reduce the burden on nursing staff. In addition, the gauze mentioned above can also be embedded in an RFID tag. When liquid leakage occurs, the RFID tag receives different electrical signals and transmits it back to an RFID reader (such as the signal transmission module in other embodiments). ). In this way, the gauze and the RFID reader can be placed separately. For example, the gauze is placed on the patient's arm, and the RFID reader is placed next to the patient's bed.
