Description

Technical Field

[0001] This utility model specifically relates to a natural bladder urination system. Background Technology

[0002] In clinical medicine, radical cystectomy (cystectomy) is commonly used to treat invasive bladder cancer, severe bladder dysfunction, or trauma. Post-surgery, patients need alternative methods to store and expel urine, which can impact their quality of life. However, with medical technology and adaptive adjustments, most patients can return to a normal life. The main methods of bladder replacement after surgery include: 1. Ileal neobladder (orthotopic bladder): This involves reshaping a section of the small intestine (usually the ileum) into a "new bladder" connected to the urethra. Patients can urinate through their original urethra. The advantages are that it closely resembles natural urination and eliminates the need for an external stoma. The disadvantages are the need for neobladder training, potential nocturnal incontinence, the need for regular catheterization to empty residual urine (for some patients), and the potential for long-term metabolic disorders (such as electrolyte imbalance); 2. Urinary tract stoma: This involves using a section of the small intestine as a urinary passage. One method involves connecting the ureter to a stoma in the abdominal wall at one end, allowing urine to flow into an external urine bag. Advantages include relatively simple surgery, fewer complications, no need for frequent catheterization, and convenient nursing care. Disadvantages include the need for lifelong ostomy bag wear, regular changes, and potential skin irritation or infection around the stoma. Another method is ureterocutaneous stoma, where the ureter is directly connected to a stoma in the abdominal wall skin, allowing continuous urine flow. An external urine collection bag is required. This method is typically used for elderly or frail patients. Disadvantages include stoma stenosis, higher risk of infection, and more complex nursing care. Currently, there is no standard bladder replacement protocol after radical cystectomy, and the surgery is highly invasive, with a high risk of postoperative complications, severely impacting the patient's quality of life. While advancements in medical technology aim to replace the bladder when it is severely and incurably compromised, finding a matching human bladder is challenging. Therefore, some artificial, natural-looking bladders have emerged in clinical medicine to replace the human bladder. For example, there is a patented solution with patent number CN202010253783.X, named "Artificial Intelligent Bladder." However, these artificial, natural-looking bladders are not only structurally complex but also require the placement of numerous electrical components within the artificial bladder. This results in a bulky structure and lower stability and safety. More importantly, traditional artificial bladders, due to their considerable weight, cause inconvenience and discomfort for patients in daily activities. Furthermore, because the weight increase with urine volume is not significant and they lack the ability to deform with increasing urine volume, patients lose the physiological signals originally provided by the natural bladder—that is, the gradual stretching of the bladder wall and the triggering of a nerve reflex to send a "full" signal to the brain as urine volume increases. This loss deprives patients of an important pathway to perceive their own physiological state, potentially leading to negative emotions such as anxiety and unease, and affecting their mental health and participation in social activities.

[0003] This utility model was developed precisely because of the aforementioned shortcomings. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a simple, compact, more stable, safer and more reliable natural bladder urination system.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model provides a natural bladder-like urination system, including an artificial bladder body and a controller connected thereto. The artificial bladder body includes an outer bladder and an elastic inner bladder disposed inside the outer bladder. The inner bladder forms a urine storage cavity for storing urine. The artificial bladder body is provided with an inlet channel and an outlet channel communicating with the urine storage cavity. The outer bladder is also connected to a switch valve for opening or closing the outlet channel. The outer wall of the inner bladder and the inner wall of the outer bladder form a sealed pressure-stabilizing cavity. The artificial bladder body is provided with a pressure detection device located in the pressure-stabilizing cavity and capable of detecting air pressure. The controller is electrically connected to the detection device to collect air pressure parameters. The controller is connected to the switch valve to control the opening and closing of the switch valve.

[0007] In the aforementioned natural bladder urination system, the inner bladder is made of a soft, elastic material, and the outer bladder is made of a rigid material; or, both the inner and outer bladders are made of elastic materials, and the elastic coefficient of the outer bladder is greater than that of the inner bladder.

[0008] As described above, in the simulated natural bladder urination system, the switching valve is a normally closed solenoid valve. The normally closed solenoid valve includes a valve base and a valve body, which together form a receiving cavity. The valve base has an inlet that connects the urine storage cavity and the receiving cavity. The valve body has an outlet that communicates with the receiving cavity. The receiving cavity contains a plug that can move up and down. An elastic element is provided between the plug and the valve base to push the plug to block the outlet. The plug has a permanent magnet core. The valve body has a winding cavity surrounding the receiving cavity. The winding cavity contains a winding coil that can form a closed magnetic circuit with the permanent magnet core, thereby pushing the plug away from the outlet.

[0009] As described above, the simulated natural bladder urination system includes a controller equipped with a control circuit board, a power supply, operation buttons, and a display screen. The control circuit board is electrically connected to the air pressure detection device, the switching valve, and the display screen. The power supply is electrically connected to the control circuit board and can provide power to the air pressure detection device, the switching valve, and the display screen.

[0010] As described above, the controller of the simulated natural bladder urination system is further equipped with one or more of the following: an audible alarm device, a light alarm device, and a vibration device, which are electrically connected to the control circuit board.

[0011] As described above, the artificial bladder body of the simulated natural bladder urination system further includes an upper mounting component and a lower mounting component. The top of the outer bladder and the top of the inner bladder are both connected to the upper mounting component, and the bottom of the outer bladder and the bottom of the inner bladder are both connected to the lower mounting component.

[0012] As described above, in the simulated natural bladder urination system, the inlet channel extends through the upper mounting assembly, the upper mounting assembly is connected to a connecting pipe, the connecting pipe includes a main pipe inserted into the inlet channel, and the top of the main pipe is connected to two branch pipes for connecting to the ureter.

[0013] As described above, the simulated natural bladder urination system includes an upper mounting assembly comprising an upper mounting seat connected to an upper connector, the upper mounting seat and the upper connector clamping and fixing the outer bladder body, the upper connector connected to an upper fixing member, and the upper connector and the upper fixing member clamping and fixing the inner bladder body; the fluid outlet channel extends through the lower mounting assembly, which includes a lower mounting seat connected to a lower connector, the lower mounting seat and the lower connector clamping and fixing the outer bladder body, the lower connector connected to a lower fixing member, and the lower connector and the lower fixing member clamping and fixing the inner bladder body; the lower fixing member has a recessed fluid collection groove in its middle, and the top opening of the fluid outlet channel is located in the middle of the fluid collection groove.

[0014] As described above, in the simulated natural bladder urination system, the upper and lower fixing components are connected by a vertically penetrating support column tube. The upper part of the support column tube is connected to the inlet channel, and the lower part is connected to the outlet channel. The side wall of the support column tube has a urination side port that connects its inner cavity to the urine storage cavity.

[0015] In the simulated natural bladder urination system described above, the switch valve is connected to the bottom of the lower mounting assembly, and the switch valve is wrapped with a protective shell made of soft material.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. Natural Simulation of Human Physiological Response: The inner bladder is made of elastic materials (such as medical-grade silicone and polyurethane), which can automatically expand or contract according to changes in urine volume. This design closely resembles the working mechanism of the human bladder, providing patients with a more natural user experience and helping to reduce the psychological burden caused by long-term reliance on external devices. Furthermore, due to the product's lightweight structure and the bladder's ability to expand to a certain extent, patients have a more natural perception of changes in the weight and volume of urine. This allows for a constant simulation of the bladder's real sensation as urine increases, which is then accurately fed back to the patient through the system. This precise system control of urination provides a more realistic experience, helping patients more accurately perceive when they need to urinate and promoting interaction between the patient and the device, making the experience feel closer to natural physiological states.

[0018] 2. Optimized pressure regulation mechanism: The inner sac gradually expands when storing urine, increasing the air pressure in the pressure regulating chamber. This physical principle-based pressure regulation mechanism not only simplifies the system's design complexity but also improves its reliability and response speed. Real-time monitoring and feedback to the controller via an air pressure detection device ensures that the urination process begins at the appropriate time, preventing risks caused by excessive expansion of the inner sac.

[0019] 3. Enhanced safety performance: Due to the elasticity of the inner sac, a certain level of safety can be ensured even in emergencies (such as power outages). Even if the valve malfunctions, the elasticity of the inner sac can mitigate the dangers of excessive urine storage, providing patients with additional safety. Attached Figure Description

[0029] The utility model will be further described below with reference to the accompanying drawings:

[0030] The orientations described in this utility model specification, such as "up," "down," "left," "right," "front," and "back," are based on the orientations in the accompanying drawings and are intended to facilitate the description of the relationships between the various components. They do not indicate the unique or absolute positional relationships between the various components, but are merely one embodiment of the utility model and are not a limitation on its implementation.

[0031] Example 1

[0032] This embodiment describes a natural bladder urination system, such as... Figure 1 and Figure 2 As shown, this system includes an artificial bladder body 1 and a controller 2 connected to it. The artificial bladder body 1 is placed in the patient's original bladder location. To improve stability, in actual clinical applications, a connection hole is usually provided in the artificial bladder body 1. Surgical sutures are passed through the connection hole and sutured to the body, making the artificial bladder body 1 less prone to shaking. The controller 2 is located outside the patient's body and is connected to the artificial bladder body 1 via a connection line, similar to the method of inserting a urine bag after surgery. For detailed structure, see [reference needed]. Figures 3 to 6As shown, the artificial bladder body 1 includes an outer capsule 11 and an elastic inner capsule 12 disposed inside the outer capsule 11. The inner capsule 12 forms a urine storage cavity 100 for storing urine. The artificial bladder body 1 is provided with an inlet channel 101 and an outlet channel 102 communicating with the urine storage cavity 100. The inlet channel 101 is used to communicate with a renal catheter, while the outlet channel 102 extends to the outside of the body through a tube. The outer capsule 11 is also connected to a valve 13 for opening or closing the outlet channel 102. The outer wall of the inner capsule 12 is connected to the outer... The inner walls of the bladder 11 form a sealed pressure-stabilizing cavity 103. The artificial bladder body 1 is equipped with a pressure detection device 14 located within the pressure-stabilizing cavity 103 and capable of detecting air pressure. The controller 2 is electrically connected to the detection device to collect air pressure parameters. The controller 2 is also connected to a switching valve 13 to control its operation. The pressure detection device 14 can be a general air pressure sensor, and the switching valve 13 can be a general solenoid valve. Thus, as urine is continuously stored in the urine storage cavity 100, the inner bladder 12 expands to a certain extent. Figures 4 to 5 This causes the air pressure in the pressure stabilizing chamber 103 to rise continuously. This can be detected in time by the air pressure detection device 14 and controlled by the controller 2 to open the valve 13 for urination. The degree to which the air pressure in the pressure stabilizing chamber 103 can rise depends on the pressure of the liquid coming out of the urination tube, so the safety performance is extremely high. In this embodiment, the inner capsule 12 is generally made of soft and elastic materials such as medical silicone, polyurethane (PU), polytetrafluoroethylene, and thermoplastic elastomer (TPE), while the outer capsule 11 can be made of rigid materials. The outer capsule 11 can also be made of the same material as the inner capsule 12. In this case, it is necessary to ensure that the wall thickness of the outer capsule 11 is much larger than that of the inner capsule 12. In other words, the stiffness of the outer capsule 11 should be greater than that of the inner capsule 12. What is the advantage of the small deformation capability of the outer capsule 11? The small deformation capability of the outer capsule 11 allows it to expand when the pressure in the pressure stabilizing chamber 103 is too high, thereby enabling the urine storage chamber 100 to store more urine. At the same time, it can provide feedback to the patient through the tactile sensation of expansion.

[0033] As a preferred embodiment of the switch valve 13, the structure is as follows: Figure 3 and Figure 6As shown, the switching valve 13 is a normally closed solenoid valve, which includes a valve base 131 and a valve body 132, which together form a receiving cavity. The valve base 131 is provided with an inlet 133 connecting the urine storage cavity 100 and the receiving cavity. The valve body 132 is provided with an outlet 134 communicating with the receiving cavity. A plug 135 that can move up and down is provided in the receiving cavity. A space is provided between the plug 135 and the valve base for pushing the plug 135 to block the outlet 134. The elastic element 136 of the valve body 135 has a permanent magnet core 137 on it, and a winding cavity 138 surrounding the receiving cavity on the valve housing 132. A winding coil 139 is arranged within the winding cavity 138 to form a closed magnetic circuit with the permanent magnet core 137, thereby pushing the plug body 135 away from the outlet 134. When the winding coil 139 is energized, it can push the permanent magnet core 137 and the plug body 135 upwards, thereby opening the outlet 134 and achieving normal urination. As a further optimization, the switch valve 13 is connected to the bottom of the lower mounting assembly 16, and the switch valve 13 is wrapped with a soft material outer shell 19, which can also be made of soft material to improve comfort.

[0034] like Figure 7 and Figure 8 As shown, the controller 2 is equipped with a control circuit board 21, a power supply 22, an operation button 23, and a display screen 24. The control circuit board 21 is electrically connected to the air pressure detection device 14, the switch valve 13, and the display screen 24. The power supply 22 is electrically connected to the control circuit board 21 and can supply power to the air pressure detection device 14, the switch valve 13, and the display screen 24. The power supply 22 can be a general rechargeable lithium battery or a replaceable battery cell.

[0035] As a better solution, such as Figure 7 and Figure 8 As shown, the controller 2 is also equipped with a sound alarm device 25, a light alarm device 26, and a vibration device 27 electrically connected to the control circuit board 21. The sound alarm device 25 can be a horn or a buzzer, the light alarm device 26 is an LED light, and the vibration device 27 is a micro motor connected to an eccentric component. Of course, one or more of these can be set. In this way, when the air pressure detection device 14 detects high air pressure, the controller 2 can remind the patient through the display screen 24 or the sound alarm device 25, the light alarm device 26, or the vibration device 27, and promptly control the switch valve 13 to open for urination by pressing the button 23.

[0036] In a preferred embodiment, the control circuit board 21 is preset with a power setting for the vibration device 27. As the urine storage in the urine storage cavity 100 increases, the inner sac 12 continuously expands. The pressure change detected by the pressure detection device 14 corresponds to the increase in the amount of urine stored. The real-time display on the screen 24 is generated through the equivalent conversion between the amount of urine stored and the pressure value. The power setting of the vibration device 27 also corresponds to this. At the same time, the vibration device 27 operates at the corresponding power setting according to the actual amount of urine stored. For example, when the urine storage volume in the urine storage chamber 100 is 200ml, 300ml, and 400ml, the corresponding air pressure values ​​in the pressure stabilizing chamber 103 are P1, P2, and P3, respectively. The air pressure values ​​P1, P2, and P3 in the pressure stabilizing chamber 103 correspond to the working power levels R1, R2, and R3 of the vibration device 27. When the urine storage volume in the urine storage chamber 100 is 200ml, the display screen 24 shows the air pressure value P1 or the corresponding warning level, and the vibration device 27 operates at the R1 level to provide a reminder. This can be repeated, and there can be four or more levels.

[0037] To be more specific, such as Figure 6 As shown, in order to facilitate manufacturing and to make the structure have extremely high stability and extremely long life, the artificial bladder body 1 also includes an upper mounting assembly 15 and a lower mounting assembly 16. The top of the outer bladder 11 and the top of the inner bladder 12 are both connected to the upper mounting assembly 15, and the bottom of the outer bladder 11 and the bottom of the inner bladder 12 are both connected to the lower mounting assembly 16.

[0038] To be more specific, such as Figure 3 and Figure 6 As shown, the inlet channel 101 extends through the upper mounting assembly 15, and the upper mounting assembly 15 is connected to a connecting pipe 17. The connecting pipe 17 includes a main pipe 171 inserted into the inlet channel 101. The top of the main pipe is connected to two branch pipes 172 for connecting to the ureter. The two branch pipes 172 can be connected to the urinary catheter of the kidney by insertion and suturing.

[0039] To be more specific, such as Figure 3 and Figure 6As shown, the upper mounting assembly 15 includes an upper mounting base 151, which is connected to an upper connector 152. The upper mounting base 151 and the upper connector 152 clamp and fix the outer capsule 11. The upper connector 152 is connected to an upper fixing member 153, which clamps and fixes the inner capsule 12. The liquid outlet channel 102 penetrates the lower mounting assembly 16, which includes a lower mounting base 151. 61. The lower mounting base 161 is connected to the lower connector 162. The lower mounting base 161 and the lower connector 162 clamp and fix the outer capsule 11. The lower connector 162 is connected to the lower fixing member 163. The lower connector 162 and the lower fixing member 163 clamp and fix the inner capsule 12. The lower fixing member 163 has a recessed liquid collection groove 164 in the middle. The top opening of the liquid outlet channel 102 is located in the middle of the liquid collection groove 164 to facilitate the smooth discharge of urine.

[0040] To improve structural stability, such as Figure 3 and Figure 6 As shown, a vertically extending support column tube 18 is connected between the upper fixing member 153 and the lower fixing member 163. The upper part of the support column tube 18 is connected to the liquid inlet channel 101, and the lower part is connected to the liquid outlet channel 102. The side wall of the support column tube 18 has a urination side port 181 that connects its inner cavity to the urine storage cavity 100. The upper mounting component 15 and the lower mounting component 16 are fixed by the support column tube 18 to prevent structural deformation, and urine in the urine storage cavity 100 can also enter and exit through the urination side port 181. In this embodiment, to prevent urine in the urine storage chamber 100 from flowing back upwards due to excessive pressure or external force, a one-way check valve 182 is provided at the upper end of the support column tube 18. The one-way check valve 182 is a duckbill valve made of soft silicone. Duckbill valves are generally made of elastic materials and are flexible. The valve closure structure is that the valve outlet is flat and duckbill-shaped. It automatically opens under positive fluid pressure and closes under reverse pressure or no pressure. Its principle is that it does not require external control and relies on fluid pressure and material elastic deformation to achieve one-way flow. Of course, the one-way check valve 182 can also be an umbrella valve or a flap valve.

[0041] Example 2

[0042] This embodiment introduces a natural bladder urination system. The difference from Embodiment 1 is that the switching valve 13 in this embodiment employs a different structure, such as... Figure 9As shown, the switching valve 13 is a normally closed solenoid valve, which includes a valve base 131 and a valve housing 132, which together form a receiving cavity. Alternatively, they can be an integral structure. The housing 132 contains a soft elastic tube 130 that connects to the liquid outlet channel 102. The soft elastic tube 130 can be made of materials such as medical-grade silicone and has a certain degree of elasticity. The housing 132 also contains a movable permanent magnet core 137. An elastic element 136 for moving the permanent magnet core 137 is provided between the permanent magnet core 137 and the housing 132. At least two permanent magnet cores 137 are provided and located within the soft... The flexible tube 130 is located on both sides or around the periphery, and the permanent magnet core 137 can clamp the flexible tube 130 when it moves. The permanent magnet core 137 is surrounded by a winding coil 139. When the winding coil 139 is de-energized, the elastic element 136 pushes the permanent magnet core 137 to move and clamp the flexible tube 130, thus closing the flexible tube 130. When the winding coil 139 is energized, it pushes the permanent magnet core 137 to move and releases the flexible tube 130, restoring the flexible tube 130 to its conductive state. This design facilitates the insertion of a urinary catheter through the flexible tube 130 for clinical examination and treatment.
