Description

Technical Field

[0001] This invention relates to the field of pressure ulcer prevention technology, and in particular to a pressure ulcer prevention activity monitoring system. Background Technology

[0002] In the field of medical care, pressure ulcer prevention is a key issue for long-term bedridden patients. Long-term bedridden patients are highly susceptible to pressure ulcers due to continuous pressure on local tissues and impaired blood circulation, making regular turning and repositioning crucial.

[0003] However, in the existing nursing model, medical staff need to manually record the turning situation, which is prone to oversight due to busy work. Traditional pressure ulcer prevention products, such as pressure relief patches and pressure relief mattresses, can only relieve pressure and cannot monitor the turning status.

[0004] Existing monitoring devices have several significant drawbacks: 1. Image recognition-based systems require cameras, posing a risk of privacy breaches, and are also costly and susceptible to environmental interference; 2. Mattress monitoring devices that rely on pressure sensors are prone to misjudgment due to slight limb movements, resulting in insufficient accuracy; 3. Some monitoring patches with electronic components require built-in batteries or wires, leading to poor patient comfort and even safety hazards such as tangled wires and battery allergies.

[0005] In addition, the existing equipment is poorly integrated with information management, and medical staff cannot keep track of patients' status in real time through mobile terminals (such as APPs), resulting in low nursing efficiency.

[0006] Therefore, there is an urgent need for a solution that combines pressure ulcer prevention, accurate turning monitoring, high comfort, and integration with information systems.

[0007] In response, the inventor of this patent, combining clinical experience, reflecting on problems encountered in clinical work, reviewing a large amount of scientific research data and literature, and conducting a novelty search, gradually conceived and designed this application to solve the relevant technical problems. Summary of the Invention

[0008] This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, the object of this invention is to provide a pressure ulcer prevention activity monitoring system.

[0009] To achieve one of the above objectives, an anti-pressure ulcer activity monitoring system according to an embodiment of the present invention includes a body position monitoring patch, a radio frequency transceiver, and a monitoring terminal;

[0010] Two body position monitoring patches are provided. Each body position monitoring patch includes an anti-pressure sore patch, a passive sensing chip embedded in the anti-pressure sore patch, an RF antenna connected to the passive sensing chip, and a height position detection sensor. The RF transceiver is RFly connected to the passive sensing chip through the RF antenna, and the RF transceiver is wirelessly connected to the monitoring terminal.

[0011] The two anti-pressure sore patches are applied to the left and right sides of the human skin so that the two height position detection sensors are located on the left and right sides of the human body respectively.

[0012] When the difference in relative height position change between the two height position detection sensors is less than the alarm preset value within a preset time range, the detection signal is transmitted to the passive sensing chip. The passive sensing chip processes the detection signal and transmits the processed detection signal to the radio frequency transceiver through the radio frequency antenna. The processed signal is then transmitted to the monitoring terminal through the radio frequency transceiver. The monitoring terminal outputs an alarm based on the processed detection signal.

[0013] In addition, the pressure ulcer prevention activity monitoring system according to the above embodiments of the present invention may also have the following additional technical features:

[0014] According to one embodiment of the present invention, the pressure ulcer patch is deformable upon pressure so that it can be tightly adhered to the skin surface.

[0015] According to one embodiment of the present invention, the pressure ulcer patch is made of a copolymer of butene copolymer, gelatin, polypropylene glycol and ethylene-vinyl acetate, and the bottom surface of the pressure ulcer patch is provided with a tear film, and the edge of the tear film is provided with tear loops.

[0016] According to one embodiment of the present invention, the altitude position detection sensor is a high-precision barometric pressure sensor.

[0017] According to one embodiment of the present invention, the radio frequency transceiver includes a housing, a microcontroller disposed in the housing, a radio frequency transceiver module, a power supply module, and a wireless module A for wirelessly connecting with the monitoring terminal;

[0018] The radio frequency transceiver module, the power supply module, and the wireless module A are all connected to the microcontroller.

[0019] According to one embodiment of the present invention, the radio frequency transceiver further includes a power switch and a charging interface;

[0020] The power switch is connected to the microcontroller; the power module is a high-power rechargeable battery; the charging interface is connected to the power module through a charging protection circuit, and the charging protection circuit is also connected to the microcontroller.

[0021] According to one embodiment of the present invention, the radio frequency transceiver further includes a battery power detection circuit for detecting the power level of the power module and a display module for displaying the power level of the power module;

[0022] The battery power detection circuit is connected between the power module and the microcontroller; the display module is connected to the microcontroller.

[0023] According to one embodiment of the present invention, the radio frequency transceiver further includes a binding setting module connected to the microcontroller for binding the two body position monitoring patches;

[0024] Each of the passive sensing chips embedded inside the body position monitoring patch has a unique ID address code; the display module is also used to display the ID address code;

[0025] When two of the ID address codes are selected through the binding settings module, the two body position monitoring patches are respectively bound to the monitoring terminal.

[0026] According to one embodiment of the present invention, the monitoring terminal is a smartphone or smart tablet, including a main controller, an alarm threshold setting module for setting the alarm preset value, a display screen for displaying the alarm preset value, an alarm reminder module, and a wireless module B for connecting to the wireless module A;

[0027] The alarm threshold setting module, display screen, alarm reminder module, and wireless module B are all connected to the main controller.

[0028] According to one embodiment of the present invention, the alarm reminder module is a sound alarm, a light alarm, a vibration alarm, or a sound and light alarm; the wireless module A and the wireless module B are both Bluetooth modules, WiFi modules, 4G modules, or 5G modules.

[0029] The beneficial effects of this invention are:

[0030] Firstly, the pressure ulcer prevention activity monitoring system provided in this application, in its specific implementation, only embeds the passive sensing chip, radio frequency antenna, and height position detection sensor inside the two body position monitoring patches. It can obtain current and work by Faraday electromagnetic induction. Neither of them has a battery or needs to use a power connection cable to connect to an external power source, which makes the whole system very small, exquisite, and very thin. When it is attached to the user's skin, the user is not likely to feel a foreign body sensation, so it is not likely to cause discomfort. This makes the application safe and reliable to use, and can better avoid the safety risks of battery explosion and the safety hazards of power connection cables entangled in the user's body. Therefore, the overall use of this application is safe and comfortable.

[0031] Secondly, this application employs two position monitoring patches to monitor the user's turning over. Pre-set alarm preset values ​​are configured based on the patient's body size and the placement of the two position monitoring patches. Within a preset time range, if the user does not turn over in bed or the turning motion is small, resulting in minimal change in the relative height of the two height position detection sensors, and the height position difference within the current preset time range remains less than the alarm preset value, the monitoring terminal will issue an alarm at the alarm node within the preset time range. This alerts medical staff and / or the user's family to urge or assist the user lying in bed to turn over in accordance with the required standards to prevent pressure sores. The two position monitoring patches are used... The monitoring patch performs collaborative monitoring, which is significantly more accurate than traditional monitoring devices that only use a single body position monitoring patch. Traditional devices often fail to trigger an alarm when the user makes slight movements or turns over, leading to monitoring failures and misjudgments. This application improves the accuracy of user turning over monitoring because when the user makes slight movements or turns over in bed, the difference in height position changes between the two height position detection sensors will not exceed the alarm preset value. As a result, the monitoring terminal will issue an alarm at the alarm node within the preset time range to verify that the user's slight movements or turns over in bed are invalid. This makes the application highly reliable and provides high accuracy in judging user turning over.

[0032] Thirdly, the overall structure of this application is simple, including only two of the aforementioned body position monitoring patches, one of the aforementioned pressure ulcer alarm reminders, and one of the aforementioned monitoring terminals, which makes the cost of use low, less susceptible to environmental interference, and compared with traditional turning over image recognition systems, there is no risk of leaking user privacy, and it also makes the efficiency of turning over monitoring and care high.

[0033] Fourthly, because the pressure ulcer patch is made of a copolymer of butene, gelatin, polypropylene glycol, and ethylene-vinyl acetate, it has a soft texture and can be molded into any desired shape under certain constraints. It also has inherent adhesiveness, allowing it to be molded and deformed when pressed, so that it can be closely adhered to the user's skin surface. Even if the area on the user's skin surface where the patch needs to be applied is uneven, it can still be molded and deformed to adhere closely to the uneven area of ​​the user's skin surface, making it highly adaptable to use. Furthermore, because the pressure ulcer patch is soft in texture, it obviously also has pressure-reducing properties, which allows it to disperse local pressure when it is applied to the user's skin, thus playing a basic role in preventing pressure ulcers.

[0034] Fifthly, the radio frequency transceiver described in this application has radio frequency signal transmission and reception functions to enable wireless power supply to the two body position monitoring patches. It also has its own power supply, allowing for external charging and automatic power display, making its functions comprehensive and meeting user needs. The monitoring terminal described in this application has an alarm function that alerts the user when their turning-over movement is substandard or absent within a preset time, and also has an alarm threshold setting function, making it similarly comprehensive and meeting user needs.

[0035] Sixthly, each of the position monitoring patches in this application has a unique ID address code embedded in its passive sensing chip; the display module of the radio frequency transceiver is also used to display the ID address code; when two ID address codes are selected through the binding setting module of the radio frequency transceiver, the two position monitoring patches will be bound to the radio frequency transceiver respectively. Therefore, after binding, the radio frequency transceiver will only receive and process the data monitored by the two position monitoring patches bound to it, which effectively avoids data cross-contamination between different patients, especially when two or more patients in the same ward use one set of this application, thus optimizing the overall reliability of this application.

[0036] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0081] The pressure ulcer prevention activity monitoring system 1000 of the present invention will now be described in detail with reference to the accompanying drawings.

[0082] Reference Figures 1 to 7 As shown;

[0083] The pressure ulcer prevention activity monitoring system 1000 provided according to an embodiment of the present invention includes a body position monitoring patch 10, a radio frequency transceiver 20, and a monitoring terminal 30;

[0084] The body position monitoring patch 10 includes two patches, each comprising an anti-pressure sore patch 101, a passive sensing chip 102 embedded within the anti-pressure sore patch 101, a radio frequency antenna 103 connected to the passive sensing chip 102, and a height position detection sensor 104. A radio frequency transceiver 20 is radio frequency connected to the passive sensing chip 102 via the radio frequency antenna 103, and is wirelessly connected to the monitoring terminal 30. The two anti-pressure sore patches 101 are correspondingly applied to the left and right sides of the human skin, so that the two height position detection sensors 104 are correspondingly located on the left and right sides of the human body. For example, they are correspondingly applied to the skin of the hips on both sides of the human body, so that the two height position detection sensors 104 are correspondingly located on the left and right sides of the human body.

[0085] When the difference in relative height position change between the two height position detection sensors 104 within a preset time range is less than an alarm preset value, the detection signal is transmitted to the passive sensing chip 102. The passive sensing chip 102 processes the detection signal and transmits the processed detection signal to the radio frequency transceiver 20 through the radio frequency antenna 103, and then to the monitoring terminal 30 through the radio frequency transceiver 20. The monitoring terminal 30 outputs an alarm based on the processed detection signal.

[0086] Based on the above, it is clear that this application is mainly used as a pressure ulcer prevention activity monitoring system 1000 in specific implementation.

[0087] Specifically, in applying this application, in actual operation, in order to allow the user to lie down on the bed to rest or sleep, the two anti-pressure sore patches 101 are respectively attached to the left and right sides of the user's skin, such as being attached to the skin of the hips on both sides of the body, so that the two height position detection sensors 104 are respectively located on the left and right sides of the user's body. The radio frequency transceiver 20 is placed on the bed or beside the bed, so that the distance between it and the two body position monitoring patches 10 is within about 2 meters, and the radio frequency transceiver 20 is activated. At this time, the radio frequency transceiver 20 will be in a powered-on working state.

[0088] Since the radio frequency transceiver 20 is radio frequency connected to the passive sensing chip 102 through the radio frequency antenna 103, when the radio frequency transceiver 20 transmits a radio frequency signal at a specific frequency, the passive sensing chips 102 in the two body position monitoring patches 10 will receive the radio frequency signal through the radio frequency antenna 103 connected to them. According to Faraday's law of electromagnetic induction, an induced current will be generated in the closed loop where the two radio frequency antennas 103 are located. After circuit processing (such as rectification, voltage regulation, etc.), it can be converted into DC power required for the operation of the two passive sensing chips 102 and the two height position detection sensors 104, thereby activating the two passive sensing chips 102 to process and transmit data, and activating the two height position detection sensors 104 to operate.

[0089] Therefore, when the difference in relative height position change between the two height position detection sensors 104 is less than the alarm preset value within a preset time range (such as a set 2 or 3 hours), the detection signal will be transmitted to the passive sensing chip 102. The passive sensing chip 102 will process the detection signal and transmit the processed detection signal to the radio frequency transceiver 20 through the radio frequency antenna 103, and then to the monitoring terminal 30 through the radio frequency transceiver 20. The monitoring terminal 30 will output an alarm based on the processed detection signal. The monitoring terminal 30 can be a smartphone or a smart tablet, and can be placed at the nurse station for medical staff to keep and use, or can be used by the user's family members. The user can use this application while lying on a nursing bed in a hospital ward or while lying in bed at home. When the monitoring terminal 30 outputs an alarm based on the processed detection signal, the medical staff and / or the user's family members will be aware of it and can intervene to urge or help the user lying in bed to turn over to prevent pressure sores.

[0090] It should be noted that initially, if the two anti-pressure sore patches 101 are applied to the left and right sides of the user's skin, or to the skin of the hips on both sides of the body, so that the two height position detection sensors 104 are located on the left and right sides of the user's body, and the user is initially in a supine or prone position, the heights of the two height position detection sensors 104 will be close. Subsequently, if within a preset time range, the user does not turn over in bed or the turning movement is small, so that the relative height position changes of the two height position detection sensors 104 are not significant, and the difference in height position changes within the current preset time range is always less than the alarm preset value, then the monitoring terminal 30 will issue an alarm at the alarm node of the preset time range to remind medical staff and / or the user's family to urge or help the user lying in bed to turn over in accordance with the requirements to prevent pressure sores.

[0091] Conversely, if, within a preset time range, the user turns over in bed, causing a change in the height position of both height position detection sensors 104, and the difference in height position change within the current preset time range is equal to or greater than an alarm preset value, then the monitoring terminal 30 will not issue an alarm when the alarm node of the preset time range is reached. Furthermore, when the difference in height position change is equal to or greater than the alarm preset value, this application will perform a monitoring reset, that is, re-monitor the user's turning over within the next preset time range. The starting point of the next round of turning over monitoring within the preset time range is the time point when the difference in height position change is equal to or greater than the alarm preset value.

[0092] Similarly, when a user is lying on their side on the bed, and then rolls over from the side position to a flat or prone position, the principle of use of this application is still as described in the above paragraph, and will not be elaborated here.

[0093] Clearly, the application of this application will have the following technical effects:

[0094] On the one hand, the two body position monitoring patches 10 provided in this application each only embed the passive sensing chip 102, the radio frequency antenna 103, and the height position detection sensor 104. They can obtain current and work by Faraday electromagnetic induction. Neither of them has a battery or needs to use a power connection cable to connect to an external power source, which makes them very small, exquisite, and very thin. When they are attached to the user's skin, the user is not likely to feel any foreign object sensation, so as not to cause discomfort. This makes the application safe and reliable to use, and can better avoid the safety risks of battery explosion and the safety hazards of power connection cables entangled in the user's body. Therefore, the application is safe and comfortable to use as a whole.

[0095] On the other hand, this application uses two position monitoring patches 10 to monitor the user's turning over. The alarm preset values ​​are pre-set based on the patient's body size and the placement of the two position monitoring patches 10. If, within a preset time range, the user does not turn over in bed or the turning motion is small, resulting in minimal change in the relative height of the two height position detection sensors 104, and the difference in height position change within the current preset time range remains less than the alarm preset value, the monitoring terminal 30 will issue an alarm at the alarm node within the preset time range. This serves to remind medical staff and / or the user's family to urge or assist the user lying in bed to turn over in accordance with the required standards to prevent pressure sores. The two position monitoring patches 100 are used in this application. The monitoring patch 10 performs collaborative monitoring. Compared with the traditional method that only uses a single monitoring device similar to the body position monitoring patch 10, the traditional method does not issue an alarm when the user moves their body slightly or turns over slightly, resulting in monitoring failure and misjudgment. This application can significantly improve the accuracy of user turning over monitoring. This is because when the user moves their body slightly or turns over slightly in bed, the difference in height position change between the two height position detection sensors 104 will not exceed the alarm preset value. As a result, the monitoring terminal 30 will issue an alarm at the alarm node within the preset time range to verify that the user's slight body movement or turning over slight movement in bed is an invalid turning over. This makes the application very reliable to use and the accuracy of user turning over judgment is high.

[0096] Furthermore, the overall structure of this application is simple, including only two of the aforementioned body position monitoring patches 10, one of the aforementioned pressure ulcer alarm reminders, and one of the aforementioned monitoring terminals 30, which makes the cost of use low, less susceptible to environmental interference, and compared with traditional turning over image recognition systems, there is no risk of leaking user privacy, and it also makes the efficiency of turning over monitoring and care high.

[0097] Furthermore, through the above-mentioned optimized design, the whole constituted by this application is highly practical and has a good effect in use.

[0098] Furthermore, in a specific implementation, according to one embodiment of the present invention, the pressure ulcer patch 101 can be molded and deformed when pressed so that it can be tightly adhered to the skin surface.

[0099] Specifically, in practical applications, according to one embodiment of the present invention, the pressure ulcer patch 101 is made of a copolymer of butene copolymer, gelatin, polypropylene glycol and ethylene-vinyl acetate to form a soft medical-grade silicone patch. The bottom surface of the patch has an adhesive surface, and the non-bottom surface is coated with a non-adhesive oil film. The bottom surface of the pressure ulcer patch 101 is provided with a tear film 105, and the edge of the tear film 105 is provided with tear loops 1051.

[0100] In this regard, it is clear that:

[0101] On the one hand, users or medical staff can tear off the tear film 105 by squeezing the tear loop 1051, so that the bottom surfaces of the two anti-pressure sore patches 101 are respectively attached to the skin of the user's body on both sides, such as being attached to the skin of the hips on both sides of the body, making this application easy to use.

[0102] On the other hand, since the pressure ulcer patch 101 is made of a copolymer of butene, gelatin, polypropylene glycol and ethylene-vinyl acetate, it is soft in texture and can be molded into any desired shape under certain constraints. It also has its own adhesiveness and can be shaped and deformed when pressed so that it can be closely attached to the user's skin surface. Even if the area on the user's skin surface where the patch needs to be attached is uneven, it can still be shaped and deformed to fit closely to the uneven area of ​​the user's skin surface, making it highly adaptable to use. Moreover, since the pressure ulcer patch 101 is soft in texture, it obviously also has pressure-reducing properties, which can disperse local pressure when it is attached to the user's skin and play a basic role in preventing pressure ulcers.

[0103] Furthermore, through the above-mentioned optimized design, the overall performance of this application can be effectively improved.

[0104] Preferably, in this technical solution, according to an embodiment of the present invention, the altitude position detection sensor 104 is a high-precision barometric pressure sensor.

[0105] In this regard, it should be noted that the principle of a high-precision barometric pressure sensor is as follows: the high-precision barometric pressure sensor measures the atmospheric pressure of the current environment, and then converts the barometric pressure value into the corresponding altitude according to a preset algorithm, thereby realizing altitude monitoring. When the altitude of an object changes, the surrounding atmospheric pressure will also change accordingly, and the high-precision barometric pressure sensor can detect the altitude change accordingly.

[0106] Obviously, when the height position detection sensor 104 described in this application is a high-precision barometric pressure sensor, it is feasible to use it to monitor the user's turning over movements, and its operating principle is a mature existing technology.

[0107] Preferably, in this technical solution, when the height position detection sensor 104 is a high-precision barometric pressure sensor, it is preferably an LPS22HB barometric pressure sensor or a BMP585 barometric pressure sensor.

[0108] As existing technology, the LPS22HB barometric pressure sensor has a height measurement accuracy of up to 0.5 meters, and the BMP585 barometric pressure sensor can measure height changes of only a few centimeters, which can also accurately monitor the height position changes of an object within a range of 0.5 meters. Thus, their height measurement accuracy can meet the actual use requirements of this application. This is because when a user turns over, the height position change of the height position detection sensor 104 embedded inside the body position monitoring patch 10 is generally only about 0.5 meters.

[0109] Furthermore, high-precision barometric pressure sensors are generally small in size; for example, the BMP280 barometric pressure sensor measures 2.0 × 2.5 × 0.95 mm. 3 The HP203B barometric pressure sensor measures 3.6 x 3.8 mm and is 1.2 mm thick. This type of barometric pressure sensor can be easily attached to an object or fixed to it in other ways, moving with the object without significantly affecting its movement.

[0110] Furthermore, in a specific implementation, according to an embodiment of the present invention, the radio frequency transceiver 20 includes a housing 201, a microcontroller 202 disposed in the housing 201, a radio frequency transceiver module 203, a power supply module 204, and a wireless module A205 for wirelessly connecting with the monitoring terminal 30.

[0111] The radio frequency transceiver module 203, the power supply module 204, and the wireless module A205 are all connected to the microcontroller 202.

[0112] Therefore, by setting the radio frequency transceiver module 203, radio frequency signals can be transmitted and received, so that the radio frequency antenna 103 can be radio frequency connected to the passive sensing chip 102; by setting the power supply module 204, power is supplied to the microcontroller 202 and other electronic components, so that this application can work normally; by setting the wireless module A205, it can be wirelessly connected to the monitoring terminal 30, so as to transmit the processed detection signal to the monitoring terminal 30. When the difference in relative height position change between the two height position detection sensors 104 within a preset time range is less than the alarm preset value, the monitoring terminal 30 outputs an alarm to remind medical staff and / or family members of the user to urge or help the user lying on the bed to turn over in accordance with the standard requirements to prevent pressure sores.

[0113] Furthermore, in a specific implementation, according to an embodiment of the present invention, the radio frequency transceiver 20 further includes a power switch 206 and a charging interface 207;

[0114] The power switch 206 is connected to the microcontroller 202; the power module 204 is a high-power rechargeable battery; the charging interface 207 is connected to the power module 204 through a charging protection circuit 208, and the charging protection circuit 208 is also connected to the microcontroller 202.

[0115] Therefore, by setting the power switch 206, the radio frequency transceiver 20 can be turned on and off.

[0116] Furthermore, it can be clearly stated that the radio frequency transceiver 20 described in this application has a built-in power supply, which eliminates the trouble of using an external power supply, making this application convenient to use. By setting the charging interface 207, the power module 204 can be charged by an external power supply from time to time, so that this application can be used uninterruptedly.

[0117] Furthermore, through the above-mentioned optimized design, the overall performance of this application can be further improved.

[0118] Furthermore, in a specific implementation, according to an embodiment of the present invention, the radio frequency transceiver 20 further includes a battery power detection circuit 209 for detecting the power level of the power module 204 and a display module 210 for displaying the power level of the power module 204.

[0119] The battery power detection circuit 209 is connected between the power module 204 and the microcontroller 202; the display module 210 is connected to the microcontroller 202.

[0120] Therefore, it is clear that by setting the battery power detection circuit 209, the power of the power module 204 can be detected in real time and displayed in real time through the display module 210, so that users or medical staff can know in time and can detect when the power module 204 is low on power and charge it in time, thus making the overall reliability of this application better.

[0121] Furthermore, in this technical solution, according to an embodiment of the present invention, the radio frequency transceiver 20 further includes a binding setting module 211 connected to the microcontroller 202 for binding the two body position monitoring patches 10;

[0122] Each of the body position monitoring patches 10 has a unique ID address code embedded in its passive sensing chip 102; the display module 210 is also used to display the ID address code.

[0123] When the two ID address codes are selected through the binding setting module 211, the two body position monitoring patches 10 are respectively bound to the monitoring terminal 30.

[0124] Therefore, it is clear that after binding, the radio frequency transceiver 20 will only receive and process the data monitored by the two position monitoring patches 10 bound to it. This can effectively avoid cross-contamination of turning monitoring data between different patients, especially when two or more patients in the same ward use one set of this application, thus optimizing the overall reliability of this application.

[0125] Furthermore, in the technical solution of this application, according to an embodiment of the present invention, the monitoring terminal 30 is a smartphone or smart tablet, including a main controller 301, an alarm threshold setting module 302 for setting the alarm preset value, a display screen 303 for displaying the alarm preset value, an alarm reminder module 304, and a wireless module B305 for connecting to the wireless module A205.

[0126] The alarm threshold setting module 302, the display screen 303, the alarm reminder module 304, and the wireless module B305 are all connected to the main controller 301.

[0127] Therefore, it is clear that by setting the alarm threshold setting module 302, medical staff or family members can set the alarm preset value according to the user's body size and the placement position of the two pressure ulcer patches 101; by setting the display screen 303, the alarm preset value can be displayed in real time, so that medical staff or family members can be aware of the situation; by setting the alarm reminder module 304, an alarm is output when the difference in relative height position change between the two height position detection sensors 104 is less than the alarm preset value within a preset time range, so as to remind medical staff and / or family members to urge or help the user lying on the bed to turn over in accordance with the requirements to prevent pressure ulcers; by setting the wireless module B305, it is possible to wirelessly connect with the wireless module A205 to realize the wireless transmission of monitoring data between the radio frequency transceiver 20 and the monitoring terminal 30.

[0128] Preferably, in this technical solution, according to an embodiment of the present invention, the alarm reminder module 304 is a sound alarm, a light alarm, a vibration alarm, or a sound and light alarm; the wireless module A205 and the wireless module B305 are both Bluetooth modules, wireless WiFi modules, 4G modules, or 5G modules.

[0129] Therefore, medical staff and / or family members of the user can use the monitoring terminal 30 to output an audible alarm when the alarm reminder module 304 is an audible alarm, an optical alarm when the alarm reminder module 304 is an optical alarm, a vibration alarm when the alarm reminder module 304 is a vibration alarm, and an audible and visual alarm when the alarm reminder module 304 is an audible and visual alarm. This can effectively remind medical staff and / or family members of the user to urge or help the user lying on the bed to turn over in accordance with the required standards to prevent pressure sores.

[0130] It should be added that, in specific implementation, according to the pressure ulcer prevention activity monitoring system 1000 provided in the embodiment of the present invention, the monitoring terminal 30 further includes a data storage module 306 and an alarm cancellation key 307 connected to the main controller 301.

[0131] Therefore, by setting the data storage module 306, the effective number of times the user turns over and the time of each effective turn can be stored, so that medical staff and / or the user's family members can browse and query them. Furthermore, by setting the alarm cancellation key 307, medical staff and / or the user's family members can operate it to cancel the current alarm.

[0132] Furthermore, in specific implementation, according to the anti-pressure ulcer activity monitoring system 1000 provided in the embodiment of the present invention, the upper surface of the body position monitoring patch 10 is provided with an exposure hole 1011 facing the height position detection sensor 104, so that its monitoring end can be exposed to facilitate its monitoring of height position changes.

[0133] Other embodiments, etc., will not be described here.

[0134] In summary, the pressure ulcer prevention activity monitoring system 1000 provided in this application, in its specific implementation, only embeds the passive sensing chip 102, the radio frequency antenna 103, and the height position detection sensor 104 inside the two body position monitoring patches 10. It can obtain current and work by Faraday electromagnetic induction. Neither of them has a battery or needs to use a power connection cable to connect to an external power source, which makes the whole system very small, exquisite, and very thin. When it is attached to the user's skin, the user is not likely to feel a foreign body sensation, so it is not likely to cause discomfort. It also makes the use of this application safe and reliable, and can better avoid the safety risks of battery explosion and the safety hazards of power connection cables entangled in the user's body. Therefore, the overall use of this application is safe and comfortable.

[0135] Furthermore, this application employs two position monitoring patches 10 to monitor the user's turning over. Pre-set alarm preset values ​​are configured based on the patient's body size and the placement of the two position monitoring patches 10. If, within a preset time range, the user does not turn over in bed or the turning motion is small, resulting in minimal change in the relative height of the two height position detection sensors 104, and the difference in height position change within the current preset time range remains less than the alarm preset value, the monitoring terminal 30 will issue an alarm at the alarm node within the preset time range. This serves to remind medical staff and / or the user's family to urge or assist the user lying in bed to turn over in accordance with the required standards to prevent pressure sores. The use of two position monitoring patches... The device uses a single monitoring patch 10 for collaborative monitoring. Compared to traditional methods that rely on only one such monitoring device, the traditional method does not trigger an alarm when the user makes slight movements or turns over, leading to monitoring failures and misjudgments. This application significantly improves the accuracy of user turning over monitoring. This is because when the user makes slight movements or turns over in bed, the difference in height position changes between the two height position detection sensors 104 will not exceed the alarm preset value. As a result, the monitoring terminal 30 will issue an alarm at the alarm node within the preset time range to verify that the user's slight movements or turns over in bed are invalid. This makes the application highly reliable and provides high accuracy in judging user turning over.

[0136] Furthermore, the overall structure of this application is simple, including only two of the aforementioned body position monitoring patches 10, one of the aforementioned pressure ulcer alarm reminders, and one of the aforementioned monitoring terminals 30, which makes the cost of use low, less susceptible to environmental interference, and compared with traditional turning-over image recognition systems, there is no risk of leaking user privacy, and it also makes the efficiency of turning-over monitoring and care high.

[0137] Furthermore, because the pressure ulcer patch 101 is made of a copolymer of butene, gelatin, polypropylene glycol, and ethylene-vinyl acetate, it has a soft texture and can be molded into any desired shape under certain constraints. It also has inherent adhesiveness, allowing it to be molded and deformed when pressed, so that it can be tightly adhered to the user's skin surface. Even if the area on the user's skin surface where the patch needs to be applied is uneven, it can still be molded and deformed to adhere tightly to the uneven area of ​​the user's skin surface, making it highly adaptable to use. Moreover, because the pressure ulcer patch 101 is soft in texture, it obviously also has pressure-reducing properties, which allows it to disperse local pressure when it is applied to the user's skin, thus playing a basic role in preventing pressure ulcers.

[0138] Furthermore, the radio frequency transceiver 20 described in this application has radio frequency signal transmission and reception functions to enable wireless power supply to the two body position monitoring patches 10. It also has its own power supply, can be externally charged, and has a power level display function, making its functions comprehensive and able to meet the needs of use. The monitoring terminal 30 described in this application has the function of alarming when the user's turning over movement is not up to standard or there is no turning over movement within a preset time, and also has an alarm threshold setting function, making its functions comprehensive and able to meet the needs of use as well.

[0139] Furthermore, each of the position monitoring patches 10 in this application has a unique ID address code embedded in its passive sensing chip 102; the display module 210 of the radio frequency transceiver 20 is also used to display the ID address code; when two ID address codes are selected through the binding setting module 211 of the radio frequency transceiver 20, the two position monitoring patches 10 will be bound to the radio frequency transceiver 20 respectively. Thus, after binding, the radio frequency transceiver 20 will only receive and process the data monitored by the two position monitoring patches 10 bound to it, which can better avoid cross-contamination of turning monitoring data between different patients, especially when two or more patients in the same ward use one set of this application, thereby optimizing the overall reliability of this application.

[0140] Furthermore, the pressure ulcer prevention activity monitoring system 1000 provided in this application is indeed highly practical and has excellent performance, which makes this application inherently valuable for market promotion and will certainly be very popular and effectively popularized.
