Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a urethra closure device. Background Art

[0002] Urethral incontinence is a common urinary system disease. Patients have difficulty controlling urine, which leads to accidental leakage of urine. In modern medical technology, the use of artificial urethral closure devices for auxiliary treatment is a very common treatment method. Traditional artificial urethral closure devices usually adopt a mechanical or hydraulic design, including a control pump and a urethral cuff. These devices are designed to achieve controlled flow of urine by controlling the opening and closing state of the urethral cuff. Mechanical urethral closure devices usually include a urethral cuff and a manually operated control device. Through manual operation, the urethral cuff can be closed or opened to control the flow of urine. However, this mechanical device requires manual operation, which may be inconvenient for patients and cannot achieve automated urine control. Hydraulic urethral closure devices use a liquid control system. The device includes a control pump and a hose connected to the urethral cuff. By squeezing the control pump, the liquid enters the urethral cuff through the hose, closing it and thus preventing the flow of urine. By releasing the control pump, the liquid flows out of the urethral cuff, opening it, allowing urine to be discharged. This hydraulic design has the advantage of automation, which can achieve more convenient and reliable urine control. At the same time, by adjusting the operation of the control pump, the opening and closing speed and strength of the urethral cuff can be adjusted according to the needs of the patient. Therefore, it is very necessary to provide a mature urethral closure device.

[0003] However, one of the shortcomings of the related technology is that a single-tube connection is usually used, and the expansion bladder has only one filling port, which leads to insufficient pressure on the edge of the expansion bladder after the expansion bladder is inflated or filled with liquid, resulting in incomplete urethral closure and urine leakage. Summary of the invention

[0004] The utility model aims to solve at least one of the above technical problems.

[0005] In order to solve the above problems, the first purpose of the present invention is to provide a urethra closure device.

[0006] To achieve the first purpose of the utility model, an embodiment of the utility model provides a urethral closure device, which includes: a control pump; a urethral cuff, the urethral cuff includes a lock key end and a lock buckle end, the urethral cuff has a locked state, in the locked state, the lock key end and the lock buckle end are close to each other, the urethral cuff is provided with an expansion bag, the same side of the expansion bag is provided with a first filling port and a second filling port, the first filling port and the second filling port are respectively located at the lock key end and the lock buckle end, the first filling port and the second filling port are respectively connected to the control pump through a first hose and a second hose; wherein, the expansion bag is connected to the first hose through the first filling port, and the expansion bag is connected to the second hose through the second filling port.

[0007] When filling the expansion bag with gas or liquid, the gas or liquid enters the expansion bag from the first filling port and the second filling port through the first hose and the second hose respectively, and the gas or liquid enters the expansion bag from both ends, so that the filling inside the expansion bag is more uniform, and it is avoided that the expansion bag is inflated from one side, resulting in insufficient pressure on the edge of the expansion bag, which makes the urethra incompletely closed, and causes urine leakage. The urethral sleeve is wrapped around the outside of the urethra, and the pump controls the filling or release of the gas or liquid in the expansion bag. The expansion bag inside the urethral sleeve can expand when filled with liquid, thereby squeezing the urethra to achieve a closed state; it can shrink when emptied of liquid, loosening the urethra to achieve an open state. This device can control the closing and opening of the urethra by controlling the operation of the pump, thereby achieving the purpose of controlling urine excretion.

[0008] In the above technical solution, the ends of the first hose and the second hose close to the control pump are connected to each other to form a third hose, and the first hose and the second hose are connected to the control pump through the third hose.

[0009] The connection between the first hose and the second hose forms a third hose, which can achieve smoother liquid flow. This helps to control the pump to effectively deliver liquid to the expansion bag in the urethral cuff, and realize the conversion of the closed and open states of the urethra. By connecting the first hose and the second hose into a third hose, the connection points and interfaces can be reduced, thereby improving the stability and reliability of the system. Reducing the connection points helps to reduce the risk of leakage and ensure the stability of the device during use. By optimizing liquid flow and reducing connection points, this design helps to improve the efficiency and performance of the urethral closure device. Smoother liquid flow can improve the response speed and control accuracy of the device, thereby improving the reliability of the device. In addition, the liquid or gas enters the first hose and the second hose from the third hose and then enters the expansion bag, which can ensure that the speed at which the liquid or gas flows into the expansion bag is consistent, avoiding excessive pressure in the unilateral expansion bag.

[0010] In any of the above technical solutions, a plurality of lock keys are provided at the lock key end, and the lock keys are located on a side of the lock key end away from the expansion bag.

[0011] Through the setting of multiple lock keys, the diameter of the urethral cuff in the locked state can be adjusted according to the thickness of the user's urethra, so that the urethral cuff can fit the urethra more closely, avoiding being too tight and causing the urethra to be in a tightened state for a long time, or being too loose and causing poor urethral closure effect.

[0012] In any of the above technical solutions, a lock buckle is provided at the lock buckle end, and the lock buckle abuts against the lock key in the locked state.

[0013] The lock end is provided with a lock, and the lock and the lock key are in abutment with each other in the locked state, ensuring that the urethral closure device maintains a stable closed state during use. The lock and the lock key abut against each other, which can effectively prevent the urethral sleeve from loosening or accidentally opening, thereby ensuring that the device can effectively close the urethra, reach a closed state and achieve the expected function. This helps to prevent urine leakage or other related problems, and provides a more reliable urethral closure solution.

[0014] In any of the above technical solutions, the expansion sac has a closed state and an open state: in the closed state, the expansion sac expands and squeezes the urethra; in the open state, the expansion sac contracts and loosens the urethra.

[0015] In the closed state, the expansion bladder expands and squeezes the urethra. This can effectively block the flow of urine and achieve a closed state of the urethra. The expansion bladder in the closed state can control the excretion of urine by squeezing the urethra. This may be very beneficial for certain specific medical conditions or situations where urine control is required. In the open state, the expansion bladder contracts and loosens the urethra. This allows urine to be discharged freely through the urethra and restore normal urine flow. By switching between the two states, the urethra can be switched between closed and open states, thereby achieving the effect of artificially controlling urethral closure.

[0016] In any of the above technical solutions, the control pump is provided with a switch.

[0017] The filling or releasing of the expansion bag by the control pump can be manually controlled by the switch, thereby achieving the effect of controlling the closure of the urethra.

[0018] In any of the above technical solutions, the urethra closure device also includes a pressure compensation device, and the pressure compensation device is connected to the control pump.

[0019] The pressure compensation device is set to balance the pressure within the device to ensure the normal function and performance of the device. The pressure compensation device can help maintain the appropriate pressure level to ensure the stability and reliability of the urethral closure device.

[0020] In any of the above technical solutions, the pressure compensation device and the control pump are connected to each other through a fourth hose.

[0021] The pressure compensation device is connected to the control pump through the fourth hose, and the control pump is also connected to the urethral cuff. When the expansion bag changes from a closed state to an open state, the liquid in the expansion bag passes through the first hose, the second hose, and then enters the control pump through the third hose. The liquid in the control pump then enters the pressure compensation device through the fourth hose. The hose has good ductility, and the position of the pressure compensation device can be adjusted through the hose connection to meet different usage requirements.

[0022] In any of the above technical solutions, the pressure compensation device is provided with a fluid infusion port.

[0023] Filling liquid can be added to the pressure compensation device through the liquid infusion port to adjust the pressure strength of the urethral closure device. This ensures that the urethral closure device always maintains appropriate liquid pressure during use, providing better closure effect and comfort. Through the liquid infusion port, the amount of liquid inside the device can be increased or decreased as needed to adjust the working state and closure strength of the device to meet the needs of different patients. This flexibility and adjustability help improve the use effect and adaptability of the device.

[0024] In any of the above technical solutions, the pressure compensation device is provided with a liquid storage chamber, and the liquid storage chamber is communicated with the fourth hose.

[0025] The connection between the liquid storage chamber and the fourth hose allows the liquid in the device to be evenly distributed and flowed, thereby enhancing the stability of the device. This helps to ensure the reliability and consistency of the device during use. The presence of the liquid storage chamber allows the pressure inside the device to be balanced. When the expansion bladder expands and squeezes the urethra, the pressure inside the device increases, and the liquid storage chamber contracts to achieve the effect of balancing the pressure inside the device.

DETAILED DESCRIPTION

[0034] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific embodiments of the utility model are described in detail below in conjunction with the accompanying drawings. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict. In the following description, many specific details are set forth to facilitate a full understanding of the utility model, but the utility model can also be implemented in other ways different from those described herein, and therefore, the scope of protection of the utility model is not limited by the specific embodiments disclosed below.

[0035] Refer to the following Figures 1 to 5 The technical solutions of some embodiments of the utility model are described.

[0036] like Figure 1 , Figure 2 As shown, an embodiment of the utility model provides a urethral closure device, which includes: a control pump 100; a urethral sleeve 200, the urethral sleeve 200 includes a lock key end 201 and a lock buckle end 202, the urethral sleeve 200 has a locked state, in which the lock key end 201 and the lock buckle end 202 are close to each other, the urethral sleeve 200 is provided with an expansion bag 230, and a first filling port 231 and a second filling port 232 are provided on the same side of the expansion bag 230, the first filling port 231 and the second filling port 232 are respectively located at the lock key end 201 and the lock buckle end 202, the first filling port 231 and the second filling port 232 are respectively connected to the control pump 100 through the first hose 210 and the second hose 220; wherein, the expansion bag 230 is connected to the first hose 210 through the first filling port 231, and the expansion bag 230 is connected to the second hose 220 through the second filling port 232.

[0037] In this embodiment, the urethral closure device includes a control pump 100 and a urethral sleeve 200, and the control pump 100 and the urethral sleeve 200 are connected to each other. The urethral sleeve 200 is used to wrap around the outside of the urethra 400. When the urethral sleeve 200 is in a locked state, that is, in a state of wrapping around the outside of the urethra 400, the lock key end 201 and the lock buckle end 202 are close to each other, forming a shape similar to a ring, and the urethra 400 is wrapped in the middle of the ring. An expansion bag 230 is provided on one side of the urethra 400 of the urethral sleeve 200, i.e., on the inner side of the ring. A first filling port 231 and a second filling port 232 are provided at both ends of the same side of the expansion bag 230. The first filling port 231 and the second filling port 232 are communicated with the first hose 210 and the second hose 220, respectively. When the control pump 100 is used to fill the expansion bag 230 with liquid or gas, the liquid or gas enters the first filling port 231 and the second filling port 232 from the first hose 210 and the second hose 220, and then fills the expansion bag 230. The first filling port 231 and the second filling port 232 are located at both ends of the expansion bag 230, respectively. When filling, the filling ports at both ends can fully fill the edge of the expansion bag 230, thereby enhancing the squeezing effect of the expansion bag 230 on the urethra 400 and avoiding urine leakage.

[0038] like Figure 1 As shown, the ends of the first hose 210 and the second hose 220 close to the control pump 100 are connected to each other to form a third hose 110 , and the first hose 210 and the second hose 220 are connected to the control pump 100 through the third hose 110 .

[0039] In this embodiment, one end of the first hose 210 and the second hose 220 are connected together to form the third hose 110, and the third hose 110 is further connected to the control pump 100. When filling, the liquid or gas flowing from the third hose 110 into the first hose 210 and the second hose 220 has the same circulation speed, and then enters the expansion bag 230 at the same speed, and the filling speed of the first filling port 231 and the second filling port 232 is consistent, so as to avoid a large difference in the filling speed on both sides resulting in a poor final extrusion effect.

[0040] like Figure 1 , Figure 2 As shown, the lock key end 201 is provided with a plurality of lock keys 241, and the lock keys 241 are located on a side of the lock key end 201 away from the expansion bag 230; the lock buckle end 202 is provided with a lock buckle 242, and the lock buckle 242 abuts against the lock key 241 in the locked state.

[0041] In this embodiment, the lock key end 201 is provided with a plurality of lock keys 241, and the lock buckle end 202 is provided with a lock buckle 242. When the urethral sleeve 200 is wrapped around the outside of the urethra 400, the lock buckle 242 is stuck between the lock keys 241, so that the urethral sleeve 200 forms a quasi-ring shape, thereby preventing the urethral sleeve 200 from loosening and improving the reliability of the urethral closure device. Moreover, the lock buckle 242 can adjust the size of the ring by switching positions between different lock keys 241, thereby adjusting according to the size of the urethra 400.

[0042] like Figure 3 , Figure 4 As shown, the expansion balloon 230 has a closed state and an open state: in the closed state, the expansion balloon 230 expands and squeezes the urethra 400; in the open state, the expansion balloon 230 contracts and loosens the urethra 400.

[0043] In this embodiment, the control pump 100 fills the expansion capsule 230 with liquid or gas to expand the expansion capsule 230. At this time, the lock buckle 242 cooperates with the lock key 241 to prevent the urethral sleeve 200 from loosening. Therefore, the expansion capsule 230 expands inwardly and squeezes the urethra 400 to close the urethra 400. When the control pump 100 releases the filling in the expansion capsule 230, the expansion capsule 230 contracts and is in a released state, so that the pressure on the urethra 400 is reduced, thereby opening the urethra 400.

[0044] like Figure 1 As shown, the urethral closure device further includes: a pressure compensation device 300 , which is connected to the control pump 100 ; the pressure compensation device 300 and the control pump 100 are connected to each other through a fourth hose 310 ; and the control pump 100 is provided with a switch 120 .

[0045] In this embodiment, the pressure compensation device 300 is connected to the control pump 100. The control pump 100 can fill the liquid in the expansion bag 230 into the pressure compensation device 300 through the fourth hose 310. The release and filling of the expansion bag 230 by the control pump 100 can be manually controlled by the switch 120, so as to achieve the effect of controlling the closure of the urethra.

[0046] like Figure 5 As shown, the pressure compensation device 300 is provided with a liquid replenishing port 320 ; the pressure compensation device 300 is provided with a liquid storage chamber 330 , and the liquid storage chamber 330 is communicated with the fourth hose 310 .

[0047] In this embodiment, the pressure compensation device 300 is provided with a fluid infusion port 320 and a fluid storage chamber 330, wherein the fluid storage chamber 330 is connected to the fourth hose 310, and the fluid infusion port 320 is connected to the fluid storage chamber 330, and liquid can be added to the fluid storage chamber 330 through the fluid infusion port 320. The outer shell of the pressure compensation device 300 is made of a material with a certain elasticity. When the pressure in the fluid storage chamber 330 changes, the outer shell of the pressure compensation device 300 will have a certain degree of elastic deformation, thereby balancing part of the pressure and ensuring the reliability of the urethral closure device.
