Description

Technical Field

[0001] The present application relates to the field of nerve regulation technology, and in particular to a tibial nerve stimulation system. Background Art

[0002] There are many different ways to treat overactive bladder, and electrical stimulation is one of them. In the validation of electrical stimulation treatment, the effectiveness of the current stimulation parameters is judged by the patient's own memory of urination frequency, urine leakage or urinary incontinence. Since the statistical period is often long and most patients are elderly with poor memory, information is easily distorted, delaying treatment.

[0003] At present, common urination monitoring technologies include: integrating a pressure sensor in the container to determine the frequency and volume of urination based on the pressure. For example, the invention patent with the publication number CN201542613U and the patent name "A household electronic urination monitoring system and its dedicated urination measuring cup" discloses the installation of a Bluetooth communication module in the electronic scale. After the patient urinates, the urine volume and urination time can be obtained by placing the container containing urine on the electronic scale, and the data is stored in the electronic scale E2Rom, and the data is sent to the smartphone through the Bluetooth communication module at regular intervals. This method requires the user to urinate in a specific container, which has a poor experience and is easy to dirty the surrounding environment; the effectiveness of the electrical stimulation parameters is only judged by the frequency, and the treatment feedback cycle is long.

[0004] In summary, there is still no effective solution to the technical problems existing in the relevant technology, such as the complicated urination operation and the long feedback cycle of the effectiveness of tibial nerve stimulation.

[0005] Urinary leakage and incontinence are actually two different causes. The stimulator of the present application mainly stimulates incontinence rather than urinary leakage. Therefore, it is necessary to identify incontinence and urinary leakage in order to facilitate the refined treatment of the stimulator. Summary of the invention

[0006] A tibial nerve stimulation system is provided in an embodiment of the present application to solve the technical problems existing in the prior art of complicated urination operation and long feedback cycle of the effectiveness of tibial nerve stimulation.

[0007] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0008] In a first aspect, an embodiment of the present application provides a tibial nerve stimulation system, comprising:

[0009] Underwear body, multiple temperature sensors and stimulators,

[0010] The plurality of temperature sensors are arranged in the underwear body from inside to outside at intervals, with the position where the underwear body fits the urethra opening of the wearer as the center, for collecting temperature information;

[0011] The stimulator is configured to communicate with the multiple temperature sensors, receive first temperature information transmitted by the multiple temperature sensors, determine a first extension speed of urine in the underwear body in combination with the first temperature information and the layout positions of the temperature sensors in the underwear body, and determine a first enuresis amount of the wearer before receiving tibial nerve stimulation based on the first extension speed;

[0012] The stimulator generates a stimulation signal based on the current stimulation parameters and acts on the wearer, receives second temperature information transmitted by the multiple sensors, determines a second extension speed of urine in the underwear body in combination with the second temperature information and the arrangement position of the temperature sensor in the underwear body, and determines a second enuresis amount of the wearer after receiving the tibial nerve stimulation based on the second extension speed;

[0013] The stimulator monitors a change in the second enuresis amount compared to the first enuresis amount, and determines a stimulation effect of the current stimulation parameters based on the change in the enuresis amount.

[0014] In combination with the first aspect, in a possible design, monitoring the change in the second enuresis amount compared to the first enuresis amount, and determining the stimulation effect of the current stimulation parameter based on the change in the enuresis amount, includes:

[0015] monitoring a change in the second enuresis amount compared to the first enuresis amount, and determining that the current stimulation parameter is effective if the change in the enuresis amount indicates that the second enuresis amount is greater than the first enuresis amount, and both the first enuresis amount and the second enuresis amount are less than a first preset value, wherein the first preset value is a urine volume threshold for determining urinary incontinence of the wearer;

[0016] When the second enuresis amount is greater than the first enuresis amount, a larger second enuresis amount indicates a better tibial nerve stimulation effect under the current stimulation parameters.

[0017] In combination with the first aspect, in a possible design, the stimulator is further configured to monitor urinary incontinence of the wearer based on the second enuresis amount being greater than a first preset value.

[0018] In combination with the first aspect, in one possible design, the stimulator is also configured to shorten the time interval between the next round of tibial nerve stimulation and / or increase the stimulation duration of the next round of tibial nerve stimulation if it is monitored that the frequency of urinary incontinence of the wearer increases after receiving the tibial nerve stimulation.

[0019] In combination with the first aspect, in a possible design, the tibial nerve stimulation system further includes:

[0020] An acceleration sensor is configured to be in communication with the stimulator, and is used to collect frequency response values ​​and send the frequency response values ​​to the stimulator;

[0021] The stimulator is further configured to recognize that the wearer is leaking urine if, when the second enuresis amount is greater than the first preset value, the frequency response value is greater than a third preset value within a second preset time period before it is determined that the multiple temperature values ​​collected by the temperature sensor show an upward trend.

[0022] In combination with the first aspect, in a possible design manner, the second temperature information includes a second collection time and a second temperature value, and the second temperature information and the layout position of the temperature sensor on the underwear body are combined to determine a second extension speed of urine in the underwear body, including:

[0023] Obtaining the time difference when the second temperature values ​​collected by the multiple temperature sensors spaced from the inside to the outside with the urethral opening as the center reach the second preset value, and the temperature difference between the multiple second temperature values ​​collected by the same temperature sensor;

[0024] Based on the time difference and / or the temperature difference, a second extension speed of urine in the underwear body is determined.

[0025] In combination with the first aspect, in a possible design, the second enuresis amount is positively correlated with the second extension speed, the second extension speed is negatively correlated with the time difference, and the second extension speed is positively correlated with the temperature difference.

[0026] In combination with the first aspect, in a possible design method, the stimulator is also configured to determine, when the frequency response value is less than or equal to a third preset value, a first enuresis amount of the wearing object before receiving tibial nerve stimulation in combination with the frequency response value and the first extension speed, and to determine a second enuresis amount of the wearing object after receiving the tibial nerve stimulation in combination with the frequency response value and the second extension speed.

[0027] In combination with the first aspect, in a possible design method, the multiple temperature sensors are arranged in a ring shape around the urethral opening of the wearer to form multiple temperature testing areas, and the test position of each group of ring-shaped temperature sensors corresponds to a temperature testing area. The temperature sensor collects and sends temperature information to the stimulator. When urine flows through the temperature testing area of ​​the underwear body, the temperature of the temperature sensor corresponding to the temperature testing area rises, and the temperature information includes the first temperature information and the second temperature information.

[0028] In combination with the first aspect, in a possible design method, the temperature sensor transmits temperature information at intervals of a first preset time length, or transmits the temperature information when it is monitored that the temperature information is on an upward trend, and the temperature information includes the first temperature information and the second temperature information.

[0029] In combination with the first aspect, in a possible design, the temperature sensor is in a closed state when the worn object receives the stimulation signal.

[0030] Compared with the prior art, the tibial nerve stimulation system provided in the embodiment of the present application collects temperature information of the underwear body from the inside to the outside with the position of the underwear body fitting the urethral opening as the center. It is understandable that after the urine flows out from the position of the urethral opening, it diffuses from the center to the outside, so the temperature sensor closer to the urethral opening detects the temperature rise earlier, and the temperature sensor farther from the urethral opening detects the temperature rise, which means that the urine diffuses farther. Based on this temperature information combined with the position information, it can be used to determine the urine flow rate and flow rate. The stimulator is connected to multiple temperature sensors for communication, receives the temperature information transmitted by multiple temperature sensors, and determines the extension speed of urine in the underwear body in combination with the temperature information and the layout position of the temperature sensor in the underwear body. The extension speed reflects the amount of enuresis of the wearer, and the urination situation of the wearer can be judged by the amount of enuresis, so as to determine the stimulation effect of tibial nerve stimulation. The method of monitoring the amount of enuresis provided by the present application is that the urination monitoring device is worn on the wearer, and the relevant information is automatically identified after urination, and the wearer does not need to urinate in a specific container, so the experience is good. The amount of enuresis can be used to identify the amount of urination in real time, shortening the feedback cycle of the effectiveness of the stimulation parameters, thereby assisting the stimulator in determining the effectiveness of the current stimulation parameters.

DETAILED DESCRIPTION

[0044] In order to more clearly understand the purpose, technical solutions and advantages of the present application, the present application is described and illustrated below in conjunction with the accompanying drawings and embodiments.

The terms "first", "second", "third", etc. involved in this application are only used to distinguish similar objects and do not represent a specific ordering of the objects.

[0046] There are many different methods for treating overactive bladder, and electrical stimulation therapy is one of them. The following takes the stimulator as an electrical stimulation device as an example to illustrate the embodiment of the present application.

[0047] In the current electrical stimulation therapy technology, after giving the patient electrical stimulation with the current stimulation parameters, it is necessary to combine the patient's urination data to judge the effectiveness of the electrical stimulation parameters. For example, a pressure sensor is integrated in the container to determine the frequency and volume of urination based on the pressure. This method requires the user to urinate in a specific container, which has a poor experience and is easy to soil the surrounding environment; the effectiveness of the electrical stimulation parameters is only judged by the frequency, and the treatment feedback cycle is long.

[0048] Therefore, the embodiment of the present application proposes a scheme for determining the amount of urination by monitoring the amount of enuresis. Specifically, after the patient urinates, the enuresis will be stained on the underwear or diapers. The more the amount of enuresis, the greater the total amount of urination, which means the better the effect of tibial nerve stimulation.

[0049] An embodiment of the present application provides a tibial nerve stimulation system, including a urination monitoring device and an electrical stimulation device. The urination monitoring device is worn on a patient (i.e., a wearer), and a detection end is attached to the perineum of the wearer to collect the amount of enuresis of the wearer; the electrical stimulation device determines the effectiveness of the electrical stimulation parameters based on changes in the amount of enuresis over multiple times. Figure 1 A monitoring result diagram provided in an embodiment of the present application is shown. Figure 1 As shown, the urination monitoring device transmits data indicating the amount of enuresis to the electrical stimulation device. Before receiving electrical stimulation, the amount of enuresis is small, and after receiving electrical stimulation, the amount of enuresis is large. The electrical stimulation device determines that the current stimulation parameters are effective. Figure 2 Another monitoring result diagram provided by the embodiment of the present application is shown in FIG. Figure 2 As shown, the urination monitoring device transmits data indicating the amount of enuresis to the electrical stimulation device. Before receiving electrical stimulation, the amount of enuresis is small, and after receiving electrical stimulation, the amount of enuresis is small, then the electrical stimulation device determines that the current stimulation parameters are invalid.

[0050] In addition to monitoring urine output, the embodiment of the present application can also monitor whether the wearer has urinary incontinence and urine leakage. Figure 3 Another monitoring result diagram provided in the embodiment of the present application is shown in FIG. Figure 3 As shown in the figure, if the urine volume is greater than the threshold, it is determined to be urinary incontinence. If high-frequency vibration is accompanied by a period of time before urinary incontinence, it is determined to be urine leakage.

[0051] In order to monitor the urination of the wearer in real time and give timely feedback on the effect of electrical stimulation based on the urination, the embodiment of the present application eliminates the two situations of urine leakage and urinary incontinence of the wearer, and judges the normal urination volume and urination frequency of the wearer based on the amount of enuresis on the underwear body of the wearer, and judges the effectiveness of the stimulation parameters based on the comprehensive urination volume and urination frequency. Figure 4 A schematic diagram of a tibial nerve stimulation system provided in an embodiment of the present application is shown. Figure 4As shown, the tibial nerve stimulation system includes an underpants body 401, a plurality of temperature sensors 402 and an electrical stimulation device 403. The underpants body 401 includes disposable underpants, nursing underpants, ordinary underpants, etc. The plurality of temperature sensors 402 are configured to be arranged in the underpants body 401 from the inside to the outside with the position of the underpants body 401 fitting the urethra opening as the center, and collect temperature information of the underpants body 401 from the inside to the outside with the position of the underpants body 401 fitting the urethra opening as the center. It is understandable that after the urine flows out from the position of the urethra opening, it diffuses from the center to the outside, so the temperature sensor 402 closer to the urethra opening detects the temperature rise earlier, and the temperature sensor 402 farther from the urethra opening detects the temperature rise, which means that the urine diffuses farther, and based on this temperature information combined with the position information, it can be used to determine the urine flow rate and flow. The electrical stimulation device 403 is communicatively connected to multiple temperature sensors 402, receives temperature information transmitted by multiple temperature sensors 402, combines the temperature information and the layout position of the temperature sensors 402 in the underwear body 401, determines the extension speed of urine in the underwear body 401, and determines the amount of enuresis based on the extension speed.

[0052] In this embodiment, wireless communication technology is used to transmit data between the temperature sensor 402 and the electrical stimulation device 403. For example, the temperature sensor 402 transmits temperature information through a Bluetooth module, and the electrical stimulation device 403 is equipped with a module for receiving wireless signals, such as a Bluetooth receiver or a Wi-Fi module, to receive temperature information. As an example, the temperature sensor 402 and the wireless module enter a low-power mode when inactive and are only activated when data needs to be transmitted to extend the use time. In some of these embodiments, the temperature sensor 402 transmits temperature information at intervals of a first preset time, or transmits temperature information when it is detected that the temperature information is on an upward trend, wherein the first preset time can be set according to actual implementation. As an example, the first preset time is set to 5 seconds.

[0053] When urine is just discharged, its temperature is usually close to body temperature, and it is higher than the body surface and ambient temperature. Therefore, urine stained on the underwear body 401 will increase the temperature of the stained area. Then, the temperature collected by the temperature sensor 402 after urine staining is higher than the temperature collected before urine staining, which can be understood as the temperature sensor 402 collecting the temperature increase. This embodiment determines the amount of enuresis by the diffusion speed and size of urine, and determines the urination situation of the wearer by the amount of enuresis. Specifically, multiple temperature sensors 402 are arranged on the underwear body 401, and the urine diffusion speed (or diffusion speed) and size are calculated by combining the temperature information with the position of each temperature sensor 402.

[0054] The arrangement of the temperature sensor 402 is further described below with reference to the accompanying drawings. Figure 5A schematic diagram showing an arrangement of temperature sensors provided in an embodiment of the present application is shown, Figure 5 As shown, a first temperature sensor 501, a second temperature sensor 502 and a third temperature sensor 503 are arranged at intervals from the inside to the outside at the position where the underwear body 401 fits the urethral opening. Urine 504 flows out from the urethral opening, penetrates into the underwear body 401, and diffuses outward from the center. Figure 5 In the figure, the third temperature sensor 503 farthest from the center detects a temperature rise, indicating that the diffusion surface of the urine 504 is large, indicating that the urine volume is large. In addition, during the diffusion process of the urine 504, the temperature sensors 402 at different positions detect a temperature rise in a certain order, such as Figure 5 The first temperature sensor 501 first detects the temperature rise, the second temperature sensor 502 then detects the temperature rise, and the third temperature sensor 503 finally detects the temperature rise. The temperature sensors 402 arranged at different positions collect the different time points of temperature rise, and the flow rate of the urine 504 can be determined.

[0055] In some embodiments, considering that urine does not necessarily spread uniformly from the center to the outside, multiple groups of temperature sensors 402 are arranged in circles around the urination outlet, and the temperature test points of each group of temperature sensors 402 form concentric circles. Figure 6 A schematic diagram showing another arrangement of temperature sensors provided in an embodiment of the present application is shown. Figure 6 As shown, multiple temperature sensors 402 are arranged in a ring around the urethra opening of the wearer to form multiple temperature test areas. The test position of each group of ring-shaped temperature sensors 402 corresponds to a temperature test area. Figure 6 Three temperature test areas are shown, which are the first temperature test area 601, the second temperature test area 602, and the third temperature test area 603 from the inside to the outside. When a specified number of temperature sensors 402 in the temperature test area detect a temperature rise, it means that urine flows through the temperature test area. If the specified number is 1, then when any temperature sensor 402 in the temperature test area detects a temperature rise, it means that urine flows through the temperature test area where the sensor is located.

[0056] In some embodiments, the temperature information includes the collection time, the temperature value, the time difference when the temperature values ​​collected by multiple temperature sensors 402 at different distances from the urethral opening obtained by the electrical stimulation device 403 reach a second preset value, and the temperature difference corresponding to multiple temperature values ​​collected by the same temperature sensor 402; the extension speed of urine is determined based on the time difference and / or the temperature difference, and the extension speed reflects the amount of enuresis of the wearer, and the urination situation of the wearer can be judged by the amount of enuresis.

[0057] Specifically, the faster the urine spreads on the underwear body 401, the smaller the time difference of the temperature rise collected by the temperature sensors 402 at different positions, so the electrical stimulation device 403 obtains the temperature values ​​collected by multiple temperature sensors 402 at different distances from the urethral opening, calculates the time difference between the multiple temperature values, and determines the extension speed of the urine in the underwear body 401 based on the time difference. Specifically, the smaller the time difference, the faster the extension speed, the larger the enuresis amount, and the larger the urination volume; conversely, the larger the time difference, the slower the extension speed, the smaller the enuresis amount, and the smaller the urination volume.

[0058] In addition, the more the enuresis, the higher the temperature collected by the same temperature sensor 402, so the electrical stimulation device 403 obtains the temperature difference corresponding to the multiple temperature values ​​collected by the same temperature sensor 402; the extension speed of urine in the underwear body 401 is determined based on the temperature difference. Specifically, the temperature difference can be the difference between the temperature values ​​corresponding to two adjacent collection moments, or the difference between the highest temperature value and the lowest temperature value within a period of time. The larger the temperature difference, the faster the extension speed, the larger the enuresis, and the more urine is discharged; conversely, the smaller the temperature difference, the slower the extension speed, the smaller the enuresis, and the smaller the urine is discharged.

[0059] In addition, the farther the urine diffuses on the underwear body 401, the temperature sensor 402 that is farther away from the urethral opening can detect the temperature rise, so the electrical stimulation device 403 calculates whether the temperature value collected by each temperature sensor 402 has increased. When the temperature value rises, the farther the temperature sensor 402 is from the urethral opening, the more enuresis there is, and the more urine is excreted.

[0060] As an example, the amount of enuresis can be determined by combining the time difference and temperature difference mentioned above. The amount of enuresis is negatively correlated with the time difference and positively correlated with the temperature difference. Therefore, the smaller the time difference and the larger the temperature difference, the more enuresis there is, and the more urine is discharged, and vice versa.

[0061] According to the contents recorded in the above embodiments, the temperature of each position of the underwear body 401 is monitored by the tibial nerve stimulation system, and the amount of enuresis of the wearer is determined in combination with the layout position of each temperature sensor 402 and the collection time of the collected temperature. This method of monitoring the amount of enuresis does not require the wearer to urinate in a specific container, so the experience is good, more real-time and accurate, and thus can assist the electrical stimulation device 403 in determining the effectiveness of the current stimulation parameters.

[0062] The following is an introduction to the treatment feedback process. Before receiving electrical stimulation, the wearer wears a urination monitoring device, which includes a panty body 401 and multiple temperature sensors 402. The amount of enuresis on the panty body 401 after each urination of the wearer will be calculated by the electrical stimulation device 403. Then the electrical stimulation device 403 generates an electrical stimulation signal and acts on the wearer. During the electrical stimulation process, the wearer does not wear the urination monitoring device or the temperature sensor 402 in the urination monitoring device is in a closed state. After applying electrical stimulation, the amount of enuresis after each urination of the wearer is also recorded, and the amount of enuresis of the wearer before and after receiving electrical stimulation is compared to determine the effectiveness of the current stimulation parameters (or stimulation effect).

[0063] It is worth mentioning that the urination monitoring device worn by the wearer before and after receiving electrical stimulation may not be the same. The effect of the two urination monitoring devices is that both can feed back temperature information to the electrical stimulation device, and the electrical stimulation device monitors the urination results.

[0064] The above determination of the effectiveness of the current stimulation parameters includes: the electrical stimulation device 403 monitors the change in the second enuresis amount compared to the first enuresis amount, if the change in the enuresis amount indicates that the second enuresis amount is greater than the first enuresis amount, and the first enuresis amount and the second enuresis amount are both less than the first preset value, then it is determined that the current stimulation parameters are effective; in the case where the second enuresis amount is greater than the first enuresis amount, the greater the second enuresis amount, the better the tibial nerve stimulation effect under the current stimulation parameters.

[0065] The first preset value is a urine volume threshold for determining urinary incontinence of the wearer. The second enuresis volume and the first enuresis volume are both less than the first preset value, indicating that the patient's two enuresis volumes are left on the underwear body after normal urination. This embodiment excludes the situation where the wearer is stained with urine on the underwear body due to urinary incontinence, and only judges the effectiveness of the stimulation based on the change trend of the enuresis volume after multiple normal urinations of the wearer.

[0066] For electrical stimulation treatment of overactive bladder, the mode of electrical stimulation is basically 1 to 2 times a week, each time for about 1 hour. The feedback on the effectiveness of traditional stimulation depends on long-term frequency information such as the frequency of urination in 1 day. This leads to a long information feedback cycle and difficulty in comparing the effectiveness of different parameters. In this method, the amount of enuresis after each urination can be identified based on the information fed back by the urination monitoring device. The greater the amount of enuresis, the greater the total amount of urination this time, which means the better the effectiveness of electrical stimulation. Therefore, parameter effectiveness comparison can be achieved with at least one urination. Since the means of monitoring the amount of enuresis is real-time and accurate, the feedback on the effect of electrical stimulation is also more real-time and effective. The wearer can compare the effectiveness of the current stimulation parameters by urinating once before and after receiving electrical stimulation, and the feedback cycle is short.

[0067] In addition, the amount of enuresis can also be used to monitor whether the user is incontinent and leaking urine. This part is described in detail below.

[0068] The electrical stimulation device 403 obtains the time difference when the temperature values ​​collected by multiple temperature sensors 402 arranged from the inside to the outside with the urethral opening as the center reach the second preset value, as well as the temperature difference corresponding to multiple temperature values ​​collected by the same temperature sensor 402, and determines the extension speed of urine in the underwear body based on the time difference and / or the temperature difference. The extension speed is used to characterize the amount of enuresis. When the amount of enuresis is greater than the first preset value, urinary incontinence of the wearer is monitored.

[0069] Taking a human body temperature of 36.8°C (degrees Celsius) and a urine temperature of 37.5°C as an example, the second preset value may be set to 37.2°C.

[0070] In this embodiment, the temperature difference and the time difference can reflect the amount of enuresis of the wearer. If the amount of enuresis reaches the threshold, it means that the wearer is incontinent. Monitoring urinary incontinence helps caregivers analyze the frequency of urinary incontinence, urine volume, etc., so as to develop more personalized care and treatment plans, improve urinary incontinence symptoms or reduce its frequency.

[0071] In addition, the occurrence of urinary incontinence indicates that the symptoms of the wearer have worsened, so monitoring the wearer's urinary incontinence or the increase in the frequency of urinary incontinence can also assist in judging the effectiveness of the stimulation and adjusting the current stimulation parameters in a timely manner. Specifically, the intensity of tibial nerve stimulation is adjusted by monitoring the frequency of urinary incontinence. Among them, intensity refers to the time interval between each round of stimulation and / or the stimulation duration of each round of stimulation. Specifically, the electrical stimulation device can monitor the wearer's urinary incontinence based on the second enuresis volume being greater than the first preset value. If it is monitored that the frequency of urinary incontinence of the wearer after receiving tibial nerve stimulation gradually decreases, the electrical stimulation device increases the time interval between the next round of tibial nerve stimulation and / or reduces the stimulation duration of the next round of tibial nerve stimulation; if it is monitored that the frequency of urinary incontinence of the wearer after receiving tibial nerve stimulation increases, the stimulator shortens the time interval between the next round of tibial nerve stimulation and / or increases the stimulation duration of the next round of tibial nerve stimulation.

[0072] In some embodiments, the tibial nerve stimulation system includes an underpants body 401 , a plurality of temperature sensors 402 , an acceleration sensor 701 , and an electrical stimulation device 403 . Figure 7 A schematic diagram of another tibial nerve stimulation system provided in an embodiment of the present application is shown. Figure 7As shown, multiple temperature sensors 402 are arranged in the underwear body 401 from the inside to the outside with the position of the underwear body 401 fitting the urethral opening as the center, and collect temperature information of the underwear body 401 from the inside to the outside with the position of the underwear body 401 fitting the urethral opening as the center. The acceleration sensor 701 is configured to communicate with the electrical stimulation device 403, collect frequency response values, and send the frequency response values ​​to the electrical stimulation device 403. The electrical stimulation device 403 is configured to obtain the time difference when the temperature values ​​collected by multiple temperature sensors 402 at different distances from the urethral opening reach the second preset value, and the temperature difference corresponding to multiple temperature values ​​collected by the same temperature sensor. In the case where the enuresis amount is greater than the first preset value, if it is determined that the frequency response value within the second preset time length before the multiple temperature values ​​collected by the temperature sensor show an upward trend is greater than the third preset value, it is recognized that the wearer is leaking urine.

[0073] The third preset value is used to distinguish between normal activities (such as walking, sitting, and standing) and urinary incontinence. As an example, the value range of the third preset value is 0.5 m / s 2 Up to 1m / s 2 .

[0074] By intelligently monitoring the high-frequency response values ​​of the wearer during urinary incontinence, the data on urination frequency, urine leakage and urinary incontinence can also support long-term feedback, and the effectiveness comparison is more accurate. The identification information is richer and can reduce the frequent inspection of the wearer, helping medical staff better understand the causes and patterns of urine leakage, thereby providing a basis for subsequent treatment and prevention.

[0075] It is worth mentioning that urinary incontinence is a manifestation of bladder relaxation, so first rule out the possibility that the amount of enuresis on the underwear itself is caused by urinary incontinence, and then combine the amount and frequency of enuresis to determine the amount and frequency of urination, and then judge the effectiveness of the stimulation based on the frequency and urine volume.

[0076] In some of the embodiments, when the frequency response value is less than or equal to the third preset value (i.e., when non-urinary leakage is identified), the stimulator determines the amount of enuresis of the wearer in combination with the frequency response value and the extension speed. Specifically, an acceleration evaluation factor is added when evaluating the extension speed of the enuresis amount. The larger the frequency response value, the larger the extension speed is determined to be. This corrects the extension speed evaluated only by temperature information and sensor layout position, so the evaluation of the enuresis amount is more accurate.

[0077] Figure 8 A flowchart of a tibial nerve stimulation method provided in an embodiment of the present application is shown. The method is applied to a tibial nerve stimulation system. The tibial nerve stimulation system includes an underpants body 401, a plurality of temperature sensors 402, and the temperature sensors 402 are connected in communication with an electrical stimulation device 403, such as Figure 8 As shown, the method includes:

[0078] Step S801: collect temperature information of the underwear body from the inside to the outside with the position close to the urethra opening as the center through a plurality of temperature sensors arranged at different positions.

[0079] Step S802, sending the temperature information to the electrical stimulation device, the temperature information is used for the electrical stimulation device to determine the extension speed of urine in the underwear body in combination with the placement position of the temperature sensor in the underwear body, and the extension speed is used to characterize the amount of enuresis;

[0080] Step S803: adjusting the interval period and stimulation duration of the tibial nerve stimulation according to the change in the amount of enuresis of the wearer before and after receiving the tibial nerve stimulation.

[0081] This method collects temperature information at different layout positions and determines the amount of enuresis based on the layout positions. Compared with the method of measuring urine output in a specific container, this method has the advantages of real-time and convenience of detection, as well as a short feedback cycle for the effectiveness of tibial nerve stimulation.

[0082] The embodiment of the present application also provides a urination monitoring device, including: an underwear body 401, and multiple temperature sensors 402. The multiple temperature sensors 402 are arranged in the underwear body 401 from the inside to the outside, with the position where the underwear body 401 fits the urethral opening of the wearer as the center; the temperature sensor 402 heats up when urine diffuses in the underwear body 401, and the temperature sensor 402 is used to monitor the temperature data of its arrangement position. The temperature data is used for the electrical stimulation device 403 to determine the amount of enuresis in combination with the arrangement position of the temperature sensor 402 in the underwear body 401, wherein the change in the amount of enuresis of the wearer before and after receiving tibial nerve stimulation can be used to determine the therapeutic effect of the electrical stimulation.
