Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to an intelligent urination system and its usage method. Background Art

[0002] With the increasingly serious global aging problem, the number of elderly people is constantly increasing. The seventh national census shows that the population aged 60 and above is 260 million, accounting for a significant proportion. Aging or long-term illness can cause many people to be bedridden. Especially for the elderly due to long-term illness and disability, their daily living ability declines, which has become the main social situation.

[0003] Among these bedridden people, some patients have problems of urinary and fecal incontinence, and the urination time is not fixed. This not only brings great pain to the patients themselves and is not conducive to rehabilitation treatment, but also places a considerable amount of pressure and burden on the caregivers. For example, for bedridden elderly people who cannot urinate independently, their digestive and excretory systems are disordered, and the number of urination times increases significantly. Other family members need to stay on duty all day. For families with fewer children, this will cause great pressure and seriously affect the normal work and study of the children. At the same time, when patients urinate and defecate in the room, it will make the room smell bad, which is not conducive to the patients' recuperation and also causes great mental pressure and psychological impact on the patients and caregivers.

[0004] Therefore, aiming at the nursing problems of bedridden people, especially urination nursing, has become an important problem to be solved urgently.

[0005] Currently, for people who cannot urinate independently, the traditional nursing method mainly relies on manual care. Caregivers need to constantly pay attention to the urination situation of the patients and provide help when the patients have urination needs. This method not only consumes a large amount of manpower and time, but also cannot achieve real-time and accurate monitoring and intervention. For example, at night, caregivers may not be able to detect the urination needs of the patients in time due to fatigue, resulting in the situation of fecal incontinence in the patients, increasing the pain of the patients and the risk of infection.

[0006] Existing intelligent urination devices have many defects. Some fully automatic intelligent urinators include a urinator body, a water tank, an excretion tank, a flushing pipe, a sewage suction hose, etc. Although they adopt a sealed structure connected to the human body to avoid the leakage of odors, such devices are usually large in size and need to be installed in a specific position, which is not convenient for carrying and moving. For patients who need to stay in bed for a long time or have limited mobility, the usage scenarios are restricted. Moreover, their functions mainly focus on the cleaning after urination, and their monitoring and control capabilities during the urination process are weak. Some wearable devices can solve the urination problems of some bedridden people, realizing automatic assisted urination and cleaning, saving manpower and time. However, such devices may have problems with insufficient fitting, easily leading to the leakage of excreta, bringing discomfort and secondary pollution to patients. At the same time, the accuracy and stability of their sensors need to be improved, and they may not be able to accurately monitor the urination needs of patients.

[0007] Based on the many deficiencies and gaps in existing urination-related devices and methods, there is an urgent need for an intelligent urination system with a simple structure, convenient operation, and comfortable use, as well as a urination method based on this system, to meet the needs of patients and caregivers and improve the quality and efficiency of urination care. Summary of the Invention

[0008] Object of the Invention: To overcome the above deficiencies, the object of the present invention is to provide an intelligent urination system and its usage method, which have a simple structure, convenient operation, and comfortable use. Through real-time monitoring and intelligent control, it can more accurately meet the urination needs of patients or disabled elderly people, reduce the occurrence of complications, improve the quality of life, and provide a more convenient, efficient, and intelligent solution for the care of patients and disabled elderly people, with broad application prospects.

[0009] The object of the present invention is achieved through the following technical solutions: An intelligent urination system, comprising: A urination valve, which is arranged in front of the male prostate or the female bladder outlet and is used to control urination; A pressure sensor, which is arranged in the human bladder and close to the urination valve and is used to detect the pressure in the bladder; A capacity sensor, which is arranged in the human bladder and close to the urination valve and is used to detect the urine volume in the bladder; An implantable power supply, which is arranged under the human skin, and the implantable power supply is electrically connected to the urination valve, the pressure sensor, and the capacity sensor respectively and is used to supply power to the urination valve, the pressure sensor, and the capacity sensor; A wireless charging module, which is arranged under the human skin and close to the implantable power supply, and the wireless charging module is communicatively connected to the implantable power supply and is used to cooperate with an external wireless charger to charge the implantable power supply; A control chip is disposed under the human skin. The control chip is communicatively connected to a pressure sensor, a volume sensor, an implantable power source, and a wireless charging module respectively, and is configured to receive the pressure data from the pressure sensor, the urine volume data from the volume sensor, and the power data from the implantable power source, and to control the opening and closing of the urine discharge valve by controlling the on / off of the implantable power source; A control system is located outside the human body. The control system is communicatively connected to the control chip and is configured to receive signals from the control chip and send instructions to the control chip.

[0010] In the intelligent urine discharge system of the present invention, the urine discharge valve is disposed in front of the male prostate or the female bladder outlet, and can directly and accurately control the urine discharge process. For patients with abnormal urine discharge caused by problems such as urinary incontinence and prostatic hyperplasia, or disabled elderly people, it is possible to avoid the uncontrolled discharge of urine or the inability to urinate smoothly due to holding urine, and can significantly improve the quality of life.

[0011] The pressure sensor and the volume sensor can detect the pressure and urine volume in the bladder in real time. This enables caregivers or medical staff to timely understand the state of the patient's or disabled elderly person's bladder and make preparations for urine discharge in advance.

[0012] The implantable power source provides stable power support for other components of the system to ensure the normal operation of the system. The setting of the wireless charging module avoids the inconvenience of traditional wired charging. The patient does not need to perform complex charging operations frequently, and only needs to use an external wireless charger to approach the corresponding part of the body to complete charging, which improves the convenience of use and the patient's comfort level of life.

[0013] The control chip can receive the data of each sensor, and analyze and process them according to a preset program. By controlling the on / off of the implantable power source to control the opening and closing of the urine discharge valve, intelligent urine discharge control is realized. The various sensors and the control chip are communicatively connected through different communication protocols.

[0014] The wireless communication connection between the control system and the control chip enables caregivers to remotely operate the urine discharge valve outside the body, which is convenient and fast. Further, the above-mentioned intelligent urine discharge system further includes: A temperature sensor is disposed in the human bladder and close to the urine discharge valve. The temperature sensor is electrically connected to the implantable power source and communicatively connected to the control chip, and is configured to detect the urine temperature in the bladder and transmit the temperature data to the control chip. When the body temperature is abnormal, the control chip sends a reminder signal to the control system; The bladder pressure data detected by the pressure sensor and the bladder urine volume data detected by the volume sensor are respectively transmitted to the control chip. The control chip, based on the preset bladder pressure alarm critical point and urine volume alarm critical point, sends an alarm signal to the control system when the bladder pressure and urine volume reach the alarm critical points.

[0015] The urine temperature is usually close to the human body temperature. When the body temperature is abnormal, the system can send a reminder signal in time, which helps to detect health problems such as possible infections of the patient in time. For example, urinary tract infections may cause the urine temperature to rise. After the system detects the abnormal temperature, it reminds the caregiver in time for timely medical treatment.

[0016] The control chip, based on the preset bladder pressure alarm critical point and urine volume alarm critical point, sends an alarm signal when the bladder pressure and urine volume reach the critical values. This provides accurate urination reminders for the caregiver, avoiding the embarrassment and discomfort caused by the patient overholding urine or urine overflow.

[0017] Furthermore, for the above intelligent urination system, the urine discharge valve uses a microelectromagnet or a micro motor or a shape memory alloy structure to control the opening or closing action.

[0018] The urine discharge valve with a microelectromagnet uses the characteristics of electromagnetic force to achieve opening and closing. When the microelectromagnet is energized, a magnetic force is generated, and this magnetic force overcomes the resistance of the valve itself to open the urine discharge valve; when the power is cut off, the magnetic force disappears and the urine discharge valve closes. The urine discharge valve with a micro motor drives the opening or closing action of the urine discharge valve by rotation. When it is necessary to open the urine discharge valve, when the motor is energized, the motor starts to rotate, and the urine discharge valve is opened through a mechanical transmission device; when the power is cut off, the motor stops rotating and the urine discharge valve closes. The urine discharge valve with a shape memory alloy structure uses the characteristic that the shape memory alloy changes shape under specific conditions such as temperature or current to achieve opening and closing. When the shape memory alloy structure is energized, an electric current is applied to the shape memory alloy, causing its temperature to rise to a specific value, and the shape memory alloy deforms to open the urine discharge valve; when the power is cut off, the temperature of the shape memory alloy decreases and returns to its original shape, and the urine discharge valve closes.

[0019] The valve body of the urine discharge valve can be made of medical ceramics, medical polymer materials, 316L stainless steel or titanium alloy, etc., and the outside is wrapped with high molecular materials with excellent biocompatibility such as silica gel and polyurethane.

[0020] Furthermore, for the above intelligent urination system, the urine discharge valve uses a shape memory alloy structure to control the opening or closing action; the shape memory alloy structure includes a mechanical structure and a high molecular material structure wrapped outside the mechanical structure.

[0021] The mechanical structure includes: A shape memory alloy spring, and the shape memory alloy spring is electrically connected to the implanted power supply; A folding mechanical mechanism is provided inside the inner ring of a shape memory alloy spring. The upper and lower ends of the folding mechanical mechanism are respectively connected to the upper and lower rings of the shape memory alloy spring. When the shape memory alloy spring is powered on, it extends, driving the folding mechanical mechanism to extend, and the center of the mechanical structure opens, at which time the urine discharge valve opens. When the shape memory alloy spring loses power, it contracts and returns to its original shape, driving the folding mechanical mechanism to contract and squeeze towards the center of the mechanical structure, at which time the urine discharge valve closes. The materials of the polymer material structure include, but are not limited to, silicone, polyurethane, and polytetrafluoroethylene.

[0022] The shape memory alloy spring is electrically connected to an implantable power source and realizes extension and contraction through power-on and power-off, thereby driving the extension and contraction of the folding mechanical mechanism and precisely controlling the opening and closing of the urine discharge valve. The characteristics of the shape memory alloy spring enable the opening and closing response time of the urine discharge valve to be about 5 to 10 seconds, and it can withstand a pressure exceeding 5 kPa when closed, ensuring the reliability and sealing of the urine discharge valve.

[0023] The outside of the mechanical structure is wrapped with a polymer material structure with excellent biocompatibility, which not only meets the biological standards for implanting the valve body into the human body, reduces irritation, but also can adapt to the requirements of the valve body for repeated contraction and extension, ensuring the long-term and frequent use of the valve, and also isolating the heat generated when the shape memory alloy spring is powered on for a short time.

[0024] Furthermore, for the above intelligent urine discharge system, the parameters of the shape memory alloy spring include: a) The diameter of the shape memory alloy spring is 5 to 30 mm; b) The length of the shape memory alloy spring in the power-off (contracted) state is 5 to 10 mm, and the length in the power-on (extended) state is 8 to 12 mm; c) The wire diameter of the shape memory alloy spring is 0.4 to 1.2 mm, and it generates a vertical force of 0.8 to 1.2 kg when contracting, driving the folding mechanical mechanism to complete closing.

[0025] Preferably, the parameters of the shape memory alloy spring include: a) The diameter of the shape memory alloy spring is 18 mm; b) The length of the shape memory alloy spring in the power-off (contracted) state is 8 mm, and the length in the power-on (extended) state is 10 mm.

[0026] Further, in the above intelligent urination system, the folding mechanical mechanism includes a folding structure, and an upper fixing ring and a lower fixing ring that are respectively arranged parallel to the upper and lower sides of the folding structure; the upper fixing ring and the lower fixing ring have the same diameter as the shape memory alloy spring; the folding structure includes a plurality of two-section folding rods, the upper and lower ends of the two-section folding rods are on the inner wall of the shape memory alloy spring and are respectively connected to the upper fixing ring and the lower fixing ring, and the two-section folding rods are evenly distributed in a circle; a polytetrafluoroethylene film is wrapped outside the two-section folding rods.

[0027] The upper fixing ring and the lower fixing ring have the same diameter as the shape memory alloy spring, and are respectively arranged parallel to the upper and lower sides of the folding structure. This design makes the connection between the folding structure and the spring more stable, and can accurately transmit the telescopic force of the spring. When the spring expands and contracts, the upper fixing ring and the lower fixing ring can drive the folding structure to move synchronously, ensuring the opening and closing effect of the valve.

[0028] A polytetrafluoroethylene film is wrapped outside the two-section folding rods. The bending points of the two-section folding rods gather at the center of the shape memory alloy spring, squeezing the polytetrafluoroethylene film wrapped outside the two-section folding rods, which can completely seal the center of the mechanical structure and close the urine discharge valve.

[0029] Further, in the above intelligent urination system, the pressure sensor, the capacity sensor, the implantable power supply, the wireless charging module, the control chip, and the temperature sensor are all encapsulated with medical-grade polymer biomaterials, and the medical-grade polymer biomaterials include but are not limited to polytetrafluoroethylene, silica gel, and polyurethane; the control system includes but is not limited to mobile phones, tablets, computers, and smart watches.

[0030] Encapsulating each component of the system with medical-grade polymer biomaterials can reduce the body's rejection reaction to these components and improve the safety and stability of the system.

[0031] Users can choose a suitable control system according to their usage habits and actual needs. This improves the versatility and convenience of the system, making it convenient for patients and caregivers of different ages and usage abilities to use. The diverse control systems also increase the scalability of the system, facilitating future integration and interaction with other intelligent devices.

[0032] Further, in the above intelligent urination system, the control system is a mobile phone APP, and the mobile phone APP includes: a) An interface for displaying pressure, capacity, temperature, and power; b) Buttons for controlling the opening and closing of the urine discharge valve; c) Issue continuous alarm sounds and flashing prompts: When the bladder pressure exceeds the set alarm critical point, the urine volume reaches the upper limit, the body temperature is abnormal, or the battery power is insufficient, the mobile phone APP issues continuous alarm sounds and flashing prompts to remind the caregiver to provide timely care for the patient or the disabled elderly.

[0033] The present invention also relates to a method of using the intelligent urination system, including the following content: (1) Implant the urine discharge valve in front of the male prostate or the female bladder outlet; (2) Implant the implantable power supply, wireless charging module, and control chip under the human skin. Among them, the wireless charging module is implanted under the skin of the lower abdomen of the human body to facilitate charging by an external wireless charger; (3) The pressure sensor and the volume sensor continuously detect the pressure and urine volume in the bladder and transmit the data to the control chip; (4) The control chip, based on the preset bladder pressure alarm critical point and urine volume alarm critical point, when the bladder pressure and urine volume reach the alarm critical point, sends an alarm signal to the control system; (5) After receiving the alarm signal, the caregiver takes the patient or the disabled elderly to the toilet, places the patient or the disabled elderly on the toilet seat, or pads a flat bedpan for the bedridden patient or the disabled elderly. Then, the caregiver sends an instruction to open the urine discharge valve to the control chip through the control system; (6) After receiving the instruction, the control chip controls the implantable power supply to energize the urine discharge valve to open the urine discharge valve, indicating that the patient or the disabled elderly starts to urinate; (7) After urination is completed, the caregiver sends an instruction to close the urine discharge valve to the control chip through the control system. The control chip controls the implantable power supply to stop supplying power to the urine discharge valve to close the urine discharge valve; (8) The temperature sensor regularly measures the body temperature of the patient or the disabled elderly and transmits the temperature data to the control chip. When the body temperature is abnormal, the control chip sends a reminder signal to the control system; (9) The control chip continuously monitors the power of the implantable power supply. When the power is insufficient, it sends a signal indicating insufficient power to the control system, reminding to use an external wireless charger to charge the implantable power supply through the wireless charging module until the power reaches the standard; (10) If the urine discharge valve fails to open normally due to a malfunction, use endoscopic assistance to perform an emergency opening operation on the urine discharge valve to force it to open.

[0034] For most people, the normal daily bladder pressure for urination is 15 cmH2O. The alarm critical point can be set slightly higher than this value, such as 18 cmH2O. When the pressure sensor detects that the bladder pressure reaches 18 cmH2O, the control chip will send an alarm signal to the control system.

[0035] The normal body temperature of a human is between 36°C and 37°C. If the temperature sensor detects that the urine temperature is higher than 38°C or lower than 35°C, the control chip will send a reminder signal to the control system to prompt the caregiver to pay attention to the body temperature of the patient or the disabled elderly.

[0036] When the urine discharge valve cannot be opened through the normal control method due to equipment failure or other reasons, medical staff can use a special endoscope to manually open the valve through the emergency opening to ensure that the patient can urinate normally. Specifically: Use an endoscope with an opening wrench to reach the lower edge of the urine discharge valve, insert the opening wrench of the endoscope into the inner side of the lower fixing ring of the urine discharge valve to make the two fit, rotate 1 - 3 mm to disengage the lower fixing ring from the shape memory alloy spring, and the vertically two-section folding rod loses the lower support. Under the urine pressure, the vertically two-section folding rod extends and the urine discharge valve opens naturally.

[0037] Furthermore, for the usage method of the above intelligent urine discharge system, the implantation of the urine discharge valve includes the following content: (1) Fix the urine discharge valve in the male prostatic urethra through surgical operation. The position is from the front end to the rear end of the prostatic segment. The inlet of the urine discharge valve is located in the bladder, and the outlet is located in the lower side of the prostatic urethra; the inlet of the urine discharge valve is in a trumpet shape, and the large side of the trumpet shape covers the periphery of the urethral orifice, and pressure sensors, volume sensors, and temperature sensors are embedded on the large side of the trumpet shape. (2) Fix the urine discharge valve in the front section of the female urethral orifice through surgical operation. The position is a section downward from the bladder urethral orifice. The inlet of the urine discharge valve is located in the bladder, and the outlet is located in the lower side of the urethral orifice; the inlet of the urine discharge valve is in a trumpet shape, and the large side of the trumpet shape covers the periphery of the urethral orifice, and pressure sensors, volume sensors, and temperature sensors are embedded on the large side of the trumpet shape.

[0038] The design of the implantation of the urine discharge valve can better cover the periphery of the urethral orifice, and pressure sensors, volume sensors, and temperature sensors are embedded on the large side of the trumpet shape, which can more accurately sense the pressure, urine volume, and temperature changes in the bladder.

Detailed implementation manners

[0041] Next, Examples 1, 2, 3, and 4 will be combined with the attached drawings Figure 1 , 2 , 3, 4, 5, 6, 7, 8, and specific experiments to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention. Examples 1, 2, and 3 provide an intelligent urination system.

[0042] Example 1 As Figure 1 , 2As shown in the figure, the intelligent urination system described in Embodiment 1 includes a urination valve 1, a pressure sensor 2, a capacity sensor 3, a temperature sensor 4, an implantable power supply 4 and a wireless charging module 5, a control chip 6, and a control system 7 (mobile phone APP).

[0043] Specifically, the urination valve 1 is arranged in front of the male prostate or the female bladder B outlet, which can directly and effectively control the discharge of urine, avoiding problems such as urinary incontinence or obstruction, and improving the autonomy and controllability of urination for patients or disabled elderly people. The pressure sensor 2, the capacity sensor 3, and the temperature sensor 8 are respectively arranged in the human bladder and close to the urination valve 1. The pressure sensor 2, the capacity sensor 3, and the temperature sensor 8 respectively detect the pressure, urine volume, and urine temperature in the bladder in real time, providing an accurate data basis for subsequent intelligent control. The implantable power supply 4 provides stable power support for each component of the entire system to ensure the normal operation of the system. The wireless charging module 5 solves the charging problem of the implantable power supply 4, avoiding the trouble of frequent surgical battery replacement, and improving the convenience of use and quality of life for patients or disabled elderly people. The control chip 6, as the intelligent control core of the system, can process and analyze the data collected by each sensor, and control the opening and closing of the urination valve 1 according to preset conditions. At the same time, it can also monitor the power supply, ensuring the stable operation of the system. The mobile phone APP facilitates the caregiver to receive the signals sent by the system in real time and send instructions to the control chip 6 according to the situation, realizing remote control of the urination process.

[0044] Furthermore, the control chip 6 judges the data collected by the pressure sensor 2 and the capacity sensor 3 according to the preset bladder pressure alarm critical point and urine volume alarm critical point. When the bladder pressure and urine volume reach the alarm critical point, it timely sends an alarm signal to the mobile phone APP to remind the caregiver to make preparations for urination and avoid situations such as urine overflow. The bladder and urination parameters are shown in Tables 1 and 2.

[0045] Table 1 Bladder Parameters Table 2 Urine Flow Furthermore, the temperature sensor 8 indirectly reflects the body temperature by detecting the urine temperature in the bladder in real time. When the body temperature is abnormal, it timely sends a reminder signal to the mobile phone APP, which helps the caregiver to timely discover the health problems of the patient or disabled elderly person, such as whether there is an infection. For example, if the urinary system of the patient or disabled elderly person is infected, the body temperature may rise, and the temperature sensor 8 can detect and give an alarm in time.

[0046] Furthermore, the urine drainage valve 1 provides three ways to control the opening or closing of the urine drainage valve 1, namely, a micro electromagnet, a micro motor, and a shape memory alloy structure, which increases the flexibility and adaptability of the system. Different control methods are suitable for different patient needs and application scenarios.

[0047] Furthermore, medical-grade polymer biomaterials are used to encapsulate each component, such as polytetrafluoroethylene, silica gel, polyurethane, etc. These materials have good biocompatibility, can reduce the body's rejection reaction to these components, reduce the risk of infection, and improve the safety and stability of the system when used in the human body. At the same time, the encapsulation can also protect the components from the influence of the internal environment of the human body and extend their service life.

[0048] Furthermore, the mobile phone APP includes: a) An interface for displaying pressure, volume, temperature, and power, which can intuitively display key data such as pressure, volume, temperature, and power. The caregiver can understand the state of the patient's or disabled elderly person's bladder and the operation of the system at any time, providing strong support for the nursing work.

[0049] b) Buttons for controlling the opening and closing of the urine drainage valve 1; through this control button, the caregiver can conveniently remotely control the opening and closing of the urine drainage valve 1 without manual operation beside the patient, improving the nursing efficiency.

[0050] c) Emitting continuous alarm sounds and flashing prompts: when the bladder pressure exceeds the set alarm critical point, the urine volume reaches the upper limit, the body temperature is abnormal, or the power is insufficient, the mobile phone APP emits continuous alarm sounds and flashing prompts to remind the caregiver to provide timely care for the patient or disabled elderly person.

[0051] Embodiment 2 Based on the above structure of Embodiment 1, as shown in Figure 1 、 2 、3, 4, 5, 6, 7, 8.

[0052] In the intelligent urine drainage system of the present invention, the urine drainage valve 1 is controlled to open or close by a shape memory alloy structure. The shape memory alloy structure includes a mechanical structure and a polymer material structure wrapped outside the mechanical structure. The polymer material structure is wrapped outside the mechanical structure, such as silica gel, polyurethane, polytetrafluoroethylene, etc. These materials have good biocompatibility, can reduce the direct contact between the mechanical structure and human tissues, reduce the irritation and adverse reactions to the human body, improve the comfort and safety of the patient during use, and also isolate the heat generated when the shape memory alloy spring is energized for a short time.

[0053] Specifically, the mechanical structure adopts the combination of a shape memory alloy spring 11 and a folding mechanical mechanism 12 to achieve the reliable opening and closing of the urine discharge valve 1. The characteristics of the shape memory alloy spring 11 to extend when electrified and contract when powered off can precisely control the movement of the folding mechanical mechanism 12, thereby realizing the opening and closing actions of the urine discharge valve 1. This method has the advantages of fast response speed and high control precision.

[0054] Further, the folding mechanical mechanism 12 includes a folding structure, and an upper fixing ring 121 and a lower fixing ring 122 that are respectively arranged in parallel above and below the folding structure; the upper fixing ring 121 and the lower fixing ring 122 have the same diameter as the shape memory alloy spring 11; the folding structure includes a plurality of two-section folding rods 123, the upper and lower ends of the two-section folding rods 123 are on the inner wall of the shape memory alloy spring 11 and are respectively connected to the upper fixing ring 121 and the lower fixing ring 122, and the two-section folding rods 123 are evenly distributed in a circle. The upper fixing ring 121 and the lower fixing ring 122 have the same diameter as the shape memory alloy spring 11 and are connected to the two-section folding rods 123, forming a stable mechanical structure. This structure can ensure that the folding mechanical mechanism 12 accurately realizes the stretching and contracting actions under the drive of the shape memory alloy spring, thereby ensuring the normal opening and closing of the urine discharge valve 1. The evenly distributed two-section folding rods 123 in a circle make the force distribution more uniform, improving the stability and reliability of the mechanical structure.

[0055] Further, the outer side of the two-section folding rod 123 is wrapped with a polytetrafluoroethylene film 124, which has good lubrication performance, can reduce the friction and adhesion between the folding rods and between the folding rods and the surrounding tissues, ensure the smooth movement of the folding mechanical mechanism 12, extend the service life of the system, and squeezing the polytetrafluoroethylene film 124 wrapped on the outer side of the two-section folding rod 123 can completely seal the center of the mechanical structure, making the urine discharge valve 1 completely closed.

[0056] Embodiment 3 Based on the structural basis of Embodiment 2 above, as Figure 1 、 2 、3, 4, 5, 6, 7, 8 shown.

[0057] For the intelligent urine discharge system of the present invention, the parameters of the shape memory alloy spring 11 include: a) The diameter of the shape memory alloy spring 11 is 18 mm; b) The length of the shape memory alloy spring 11 in the powered-off (contracted) state is 8 mm, while the length in the electrified (extended) state is 10 mm; c) The wire diameter of the shape memory alloy spring 11 is 0.4 - 0.6 mm, and it generates a vertical force of 0.8 - 1.2 kg when contracting to drive the folding mechanical mechanism 12 to complete the closing.
