[0022] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] The terms "first", "second", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, products or devices.

[0024] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0025] At present, the treatment of neurogenic bladder in clinical practice is still mainly based on indwelling catheterization or intermittent catheterization, as well as surgery to increase bladder contractility through sacral nerve anterior root stimulation + sacral nerve posterior rhizotomy, sacral nerve regulation, etc., supplemented by medication, rehabilitation training and acupuncture treatment. After radical surgery for bladder malignant tumors, urinary diversion, bladder replacement and in situ bladder reconstruction are mainly used for treatment; among them, ileal bladder in situ reconstruction has the best effect, but it also has defects such as insufficient urination power and the need to repeatedly train the abdominal muscles to increase urination control function.

[0026] The explanations of the professional terms involved in this application are as follows:

[0027] SUI patients refer to those who suffer from stress urinary incontinence, a disease that is common in middle-aged and elderly women.

[0028] UAB patients are those with underactive bladder, a condition that affects urination and makes it difficult for them to urinate.

[0029] Embodiment 1

[0030] Embodiment 1 of the present application provides an artificial urination device, such as Figure 1 As shown, Figure 1 This is a structural block diagram of an artificial urination device provided in the first embodiment of the present application. The artificial urination device provided in the first embodiment of the present application may specifically include the following components: an artificial urination power device, a bladder pressure / capacity sensing device, an adjustable pressure-controlled electronic urination valve, a power supply, a microprocessor chip and a control system, a fault alarm and an emergency urination solution, etc. The specific functions and structures are as follows:

[0031] The artificial urination power device 101 can be a micro turbine urination pump (referred to as micro pump), whose displacement (to be optimized) is about 500-1200 ml / min. The speed of the turbine pump is designed to be variable frequency adjustable by microprocessor control, the main purpose of which is to make its urination speed as consistent as possible with the urine flow speed of normal people's natural urination (i.e. close to the physiological urination function); except for the necessary parts, the turbine pump is made of relevant medical-grade high-strength corrosion-resistant, anti-fouling (stone formation) and other artificial synthetic materials, the purpose of which is to make its weight as light and miniaturized as possible. Avoid the pump being overweight and compressing the "bladder wall" to produce corresponding complications. The discharge pipe connected to the micro pump is made of a polymer material with a certain supporting strength, so that it has a certain elasticity, flexibility and rigidity. An inflatable airbag is designed on its periphery, and the amount of inflation gas is calculated according to the mass of the micro pump. When the airbag is inflated, the average density of the entire micro pump is close to the average density of urine, the purpose of which is to allow the entire power device to float in the "center of the bladder" to avoid adhering to the wall and compressing the bladder wall and to allow it to be in the best urination state when working.

[0032] The bladder pressure / capacity sensing device 102 can be a built-in sensing device integrated into the urination power device (i.e., the above-mentioned micropump), which contains a pressure (pressure) sensing device and a bladder volume sensing device (intermittent pulse measurement of the upper and lower diameters, left and right diameters, and front and back diameters of the bladder when it is full, so as to calculate and monitor the urine volume in the bladder, such as a micro-pulse laser measurement device) or a wearable intermittent ultrasonic bladder volume measurement device. The built-in sensor directly transmits the sensing signal to the microprocessor chip, and the external sensing device converts the volume measurement signal into an electrical signal and transmits it to the microprocessor chip wirelessly.

[0033] Adjustable pressure-controlled electronic urination valve 103; the urination valve can be made of silicone or polymer with good biocompatibility, with a certain plasticity in shape, in line with the physiological curvature of the human urethra, and a length of about 3 to 5 cm (the normal length of the urethra of adult women is 3-5 cm). It is designed as a double channel near the inner opening of the urethra, one of the side channels is an adjustable pressure-controlled electronic urination valve, and the other straight channel is an emergency valve that can be mechanically unblocked from the outer opening of the urethra in an emergency. The urination valve is designed with a low-pressure soft one-way (outflow) valve near the outer opening of the urethra, the main purpose of which is to prevent urine or other waste from flowing back and pathogenic microorganisms from retrogradely entering the urinary system. The above-mentioned urination valve can be made of a drug coating material containing gentamicin, etc., the main purpose of which is to prevent infection during long-term retention.

[0034] Power supply 104; it is used to supply the power required by the urination power device and microprocessor and other devices in two ways: first, built-in rechargeable high-capacity battery; its main difficulties are the unbearable weight and volume and charging problems. The former is designed to design the battery into a certain ergonomic shape and place it outside the bladder such as the pelvic cavity or retroperitoneum; charging problem This plan intends to implant the charging circuit in the wall of the artificial urination tube to the vicinity of its outer opening, and design the outer opening of the urination tube as a common device for urination and charging interface. Of course, the above charging problem can also be solved by wireless charging. (After professional evaluation and calculation), if the current technology, energy density or capacity meets the required standards, this method of power supply can be used. Secondly, if the current conditions cannot be met or it is not suitable to use an internal power supply due to various reasons such as weight, side effects, etc., an external power supply can be used; the external power supply has many advantages, and the main difficulty lies in the connection problem. This design solution is to pass a wire through the urethra wall and then connect to an external high-capacity and high-power rechargeable battery through the side waist skin for power supply. The wire outer packaging material is made of an insulating material with high biocompatibility that meets relevant standards.

[0035] The microprocessor chip and control system 105 mainly include information (signal) acquisition program, information (signal) receiving and processing program, signal output (control) program and data storage program, etc. It receives the pressure (strength) and (or) bladder capacity sensing information from the built-in or external bladder (the bladder capacity is calculated according to a certain rule based on the measured data), monitors the bladder content, and when the pressure and (or) capacity in the bladder reaches a certain standard, an alarm is issued to the patient to remind him to prepare for urination within a certain time. When the set urination parameter standard is reached, the signal is transmitted to the control valve, and the urination valve function is tested normally. After the test is normal, the urination valve is opened for urination; when the function test is abnormal, it is re-tested. If it is found that there is a real valve failure, an alarm (such as frequency vibration) will be issued, and the patient will perform manual intervention. The signal output (urination) is mainly set according to the relevant examination and detection parameters of the patient before implantation. For example, the valve opening condition is set to the simultaneous satisfaction of pressure (pressure intensity) and time dependence, or volume dependence; the urination valve cannot be activated when the single pulse pressure (intensity) reaches or even exceeds the monitoring standard; this can avoid urinary incontinence problems such as urine leakage and urine seepage caused by excessive increase in abdominal pressure due to coughing, sneezing, etc.

[0036] Fault alarm 106 mainly includes bladder pressure (strong) / capacity monitoring alarm, urination valve function status monitoring alarm, etc.

[0037] The technical solution provided in the embodiment of the present application fundamentally solves the problem of insufficient urination power, and does not cause cumbersome problems such as the need for repeated catheterization of neurogenic bladder, or functional disorders such as insufficient urination power after radical cystectomy. The indications are wider. This solution is not only suitable for patients with neurogenic bladder (except for storage dysfunction), in situ bladder reconstruction after radical bladder tumor surgery, and stress urinary incontinence combined with underactive bladder (SUI&UAB).

[0038] Embodiment 2

[0039] Embodiment 2 of the present application provides an artificial urination device, such as Figure 2 As shown, Figure 2 This is a structural diagram of an artificial urination device provided in Example 2 of the present application. The technical scenario implemented in this embodiment is: the artificial urination device provided in Example 2 of the present application is placed in a bladder or an artificial bladder (such as Figure 2 dotted line), such as Figure 2 As shown, the dotted line range is the urine storage space of the bladder or artificial bladder, and the left and right channels above are pipes connected to the human ureter or artificial ureter. If the dotted line range is the bladder, the above structure is the human structure and will not be repeated here. If the dotted line range is the artificial bladder, the above structure is the structure of the artificial bladder. The embodiment of the present application does not involve the improvement of the artificial bladder, but only arranges part of the artificial urination device provided in the embodiment of the present application in the bladder or artificial bladder to solve the problem of urination. Therefore, the relevant structures of the human bladder and the artificial bladder will not be described in detail here. For the convenience of description, the bladder is taken as an example here. Under normal circumstances, the human body will continuously produce urine, and the urine enters the urine storage space of the bladder through the left and right channels. When the human body urinates normally, when the urine storage space reaches a certain capacity, the body will react to make the human body urinate. However, when the human body urinates abnormally, the human organs cannot transmit the information of the need to urinate through the muscles around the bladder. Furthermore, when the human body urinates normally, urination is achieved through the contraction of the muscles around the bladder. When the human body urinates abnormally (such as SUI & UAB patients), the muscles around the bladder cannot contract or the contraction is not strong enough. In this way, even if the bladder transmits the information of the need to urinate, the muscles around the bladder cannot effectively achieve urination, which leads to difficulty in urination for the patient. The artificial urination device provided in Example 2 of the present application is to effectively solve the above problems. Figure 2 The above-mentioned artificial urination device includes the following components:

[0040] The urination pump housing 11 is provided with a plurality of holes 111 connected to the urine storage space around the urination pump housing 11, so that the urine in the urine storage space can enter the space inside the urination pump housing through the plurality of holes 111. The urination pump housing 11 can also be provided with an inductive sensor, which is used to detect the pressure inside the urination pump housing or the capacity inside the urination pump housing. For the inductive sensor, different inductive sensors need to be replaced to detect different information. The manufacturer can decide which inductive sensor to use according to its own needs. The embodiment of the present application does not limit the specific expression of the inductive sensor.

[0041] The pump 10 is arranged in a urine pump housing 11, and provides power for urination, thus solving the problem that the muscles around the patient cannot effectively achieve urination.

[0042] The motor 12 provides corresponding drive for the pump 10 , driving the pump 10 to rotate to generate power.

[0043] The weight component 13 is used to adjust the overall density of the internal devices of the bladder (including but not limited to: pump 10, motor 12, urination pump housing 11 and other devices immersed in urine) to adapt the density of the artificial urination device to be close to the average density of urine. In an optional technical scenario, the above-mentioned weight component 13 can be an inflatable bag or a bionic bag. The above-mentioned bionic bag can be a bionic bag made of a material with a density lower than the density of urine. The present application does not set specific materials. The shape of the above-mentioned weight component 13 is preferably a circular ring shape or a rounded rectangular parallelepiped (with a through hole in the middle to facilitate the passage of the urination channel), so that there are no sharp corners on the periphery, which can avoid collision with the bladder wall and damage. The weight component is set here mainly to avoid the collision between the devices in the urine and the bladder wall and cause damage. In addition, it is to avoid the excessive weight of the devices in the urine from exerting pressure on the bladder, causing other complications and affecting the comfort of the user.

[0044] The urination channel 15 is connected to the pump 10 , and the pump 10 discharges urine in the urination pump housing 11 out of the body through the urination channel 15 by rotating.

[0045] The electronic valve 14 is used to control the connection or closing of the urination channel 15. One end of the electronic valve 14 is connected to the urination channel 15, and the other end is connected to the external urine channel 17. In an optional technical scenario, the periphery of the above-mentioned electronic valve 14 is also wrapped with a bionic layer, so that the electronic valve can directly contact the human bladder without affecting it. The above-mentioned bionic layer can be: bionic material, such as silicone, hydrogel and other materials. The above-mentioned electronic valve can also be provided with a control device, and the above-mentioned control device can be integrated in the electronic valve or provided separately. The specific embodiments of the present application do not limit the specific form of expression and specific control method of the above-mentioned control device.

[0046] The power supply component 16 is used to supply power to the artificial urination device. The power supply component 16 can be arranged outside the bladder ( Figure 2 Taking the setting outside as an example), it can also be set inside the bladder. When it is set inside the bladder, it can be charged by wireless charging to achieve power supply.

[0047] The above-mentioned second embodiment can specifically include the following method for realizing urination: when the urine in the bladder reaches a certain amount, the urine will seep into the urination pump housing 11 through the multiple holes 111 of the urination pump housing 11. At this time, if the motor 12 is started, the motor 12 will drive the pump 10 to rotate and input the urine from the urination channel 15 to the electronic valve 14. When the electronic valve 14 is opened, the urine will be discharged along the external urine channel 17, thereby realizing urination. When the urine is discharged to a certain amount, the motor 12 and the electronic valve 14 are turned off, and urination stops.

[0048] In an optional technical scenario, the artificial urination device further includes: a pressure capacity sensor 19 and a sensing device 18, wherein the sensing device 18 is arranged at the periphery of the external urine channel 17, the pressure capacity sensor 19 is arranged at the outside of the urination pump housing 11 or at the outside of the weight component 13, and the pressure capacity sensor 19 is electrically connected to the sensing device 18. During specific operation, the pressure capacity sensor 19 collects the pressure of urine in the bladder, and when the pressure exceeds the threshold, an electrical signal is sent to the sensing device 18, and after receiving the electrical signal, the sensing device 18 sends a sensing signal (such as vibration or sound), so that the user (the person using the human urination device) can realize the perception of urination.

[0049] In an optional technical scenario, the power supply component 16 can be an external power supply or an internal power supply. When the internal power supply is used, the internal power supply includes: a battery and a charging coil (not shown in the figure). The battery and the wireless charging coil can be arranged inside the counterweight component 13. Of course, the battery and the wireless charging coil can also be arranged in other positions, for example, between the motor 12 and the counterweight component 13. The embodiment of the present application does not limit the specific position of the battery and the wireless charging coil. When the internal power supply is used, the wireless charging coil can charge the battery, thereby powering the entire device without connecting an external power cord.

[0050] In an optional technical scenario, the electronic valve 14 may further include a mechanical switch, and the mechanical switch is used to manually open the electronic valve when a failure occurs in the electronic valve 14 .

[0051] The technical solution provided in the embodiment of the present application fundamentally solves the problem of insufficient urination power, and does not cause cumbersome problems such as the need for repeated catheterization of neurogenic bladder, or functional disorders such as insufficient urination power after radical cystectomy. The indications are wider. This solution is not only suitable for patients with neurogenic bladder (except for storage dysfunction), in situ bladder reconstruction after radical bladder tumor surgery, and stress urinary incontinence combined with underactive bladder (SUI&UAB).
