Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more specifically, to a bladder distribution valve. Background Art

[0002] Neurogenic bladder is a common disease that can occur at any age and gender. The causes are often spinal cord trauma, congenital dysplasia and central nervous system lesions. It is often accompanied by symptoms such as urinary incontinence caused by sphincter weakness, ureteral reflux and weak urination and urinary retention caused by detrusor weakness. Urinary incontinence can lead to complications such as perineal and sacrococcygeal dermatitis and pressure ulcers. Bladder urine refluxes through the ureter to the kidneys, which can cause kidney infection and kidney damage, and even lead to renal failure. For patients with severe urinary incontinence and ureteral reflux, conservative treatment, surgical treatment, physical care, psychological care and other measures are usually taken clinically, but it is difficult to solve the problem from the source due to poor efficacy. Therefore, from an engineering perspective, the development of a bladder distribution valve with artificial urethral sphincter and ureteral sphincter functions has important practical significance.

[0003] The Chinese patent document with the publication number CN110270008A discloses a magnetically controlled urethral valve, including a valve body, a valve core movably connected to the valve body, a first component connected to the valve body, the first component and the valve core are magnetically connected, and the first component and the valve core are arranged on both sides of the urethra; a positioning mechanism, the positioning mechanism includes a base and a second component slidably connected to the base, the second component is connected to the valve core through a connector, the second component is matched with a third component, and the second component and the third component are magnetically connected. The present invention adopts external magnetically controlled urination, which allows patients to adjust the opening and closing time of the urethral valve according to their own conditions, so as to reduce the compression and closure time of the urethra, and effectively reduce the necrosis of the urethra caused by long-term improper compression.

[0004] However, the above scheme can only realize the opening and closing control of the urethra, and cannot synchronously coordinate the opening and closing of the ureter. The "one-way valve" at the connection between the ureter and the bladder of a normal human body only allows urine to flow from the ureter to the bladder, and does not allow urine to flow back from the bladder to the ureter. Opening the urethral opening and closing the ureteral opening during urination is in line with the normal human body's urine storage and discharge mechanism. Summary of the invention

[0005] The purpose of the present invention is to overcome the deficiency of the prior art that the urethra tube and the ureter cannot be synchronously coordinated to control the opening and closing of the urethra tube and the ureter, and to provide a bladder distribution valve. The present invention can realize the linkage of the opening and closing of the urethra hole and the ureter hole, simulate the state of the urethra opening and the ureter hole in the normal human body as one open and one closed, and prevent urine from flowing back from the bladder to the kidney during urination.

[0006] The purpose of the present invention can be achieved by adopting the following technical solutions:

[0007] A bladder distribution valve comprises a valve body wrapped on the outer wall of the bladder, a valve core arranged on the valve body to keep the ureter normally open and the urethra normally closed, and a driving mechanism capable of changing the state of the valve core to close the ureter and open the urethra.

[0008] When the bladder in a normal human body stores urine, the urethral opening is normally closed and the ureter is normally open; when urinating, the urethral opening is open and the ureter is closed. In the unactivated state, the valve core makes the ureter normally open and the urethral opening normally closed, replacing the contraction force of the urethral sphincter. When urination is required, the drive mechanism is activated, so that the valve core moves to close the ureter and open the urethral opening, simulating normal urination. After urination is completed, the drive mechanism is closed, the valve core is reset, and the ureter is returned to the state of normally open and urethral opening.

[0009] The ureter in the human body is located above the urethral opening. The valve core can be a rod-shaped or sheet-shaped part or other part that can move up and down and is arranged on the valve body and does not affect the function. In the non-activated state, the valve core is located at the bottom to press the urethral opening closed. When urination is required, the valve core rises under the action of the driving mechanism, opens the urethral opening, and presses the ureter closed. The driving mechanism can be an electric drive or a magnet drive that cooperates with each other inside and outside the body, including a lever connected to the valve core at one end, and the other end of the lever is connected to the magnet, which can be a permanent magnet or other magnetic elements. The driving mechanism can also be other structures such as gears and racks that can apply force to the valve core to cause it to elastically deform.

[0010] The structures of the valve core, transmission mechanism and power mechanism do not affect the realization of the purpose of the present invention.

[0011] Furthermore, the valve core is provided with a ureteral hole for the ureter on the bladder to pass through, and a urethral hole for the urethra on the bladder to pass through, the ureteral hole is normally open and the urethral hole is normally closed, the connection between the drive mechanism and the valve core is located between the ureteral hole and the urethral hole, and the connection between the valve core and the drive mechanism can be lifted toward the ureteral hole, and the valve core is an elastic member covering the bladder.

[0012] In the actual structure of the human bladder, the ureter and the urethral opening are both located on the side of the bladder close to the back, the ureter is located on the side of the bladder close to the head and extends toward the head, and the urethral opening is located on the side of the bladder close to the foot and extends toward the foot. The material of the elastic member can be elastic rubber, silicone, etc., and the elastic material has a certain deformation ability. The valve core is coated on the side of the bladder with the ureter and the urethral opening, and a ureteral hole for the ureter to pass through is provided at the ureter, and a urethral hole is provided at the urethral opening. When the elastic member used as the valve core is manufactured, the two ureteral holes are circular holes cut out on the elastic sheet, and the urethral hole is a slit cut out for the urethra to pass through, so that the ureter is open in the non-working state and the urethral opening is closed under the squeezing of the urethral hole. When it is necessary to work, it is only necessary to drive the transmission mechanism to pull the part between the ureteral hole and the urethral hole on the valve core toward the ureteral hole. Under the properties of the elastic material of the valve core itself, the pulled urethral hole changes from a slit to a hole, and the squeezed ureteral hole is squeezed from a round hole to a flat slit, realizing the transition from the ureteral hole opening and the urethral hole closing to the ureteral hole closing and the urethral hole opening. After urination is completed, the force applied to the valve core is canceled, so that the valve core made of elastic material will return to its original state, that is, the ureteral hole is open and the urethral hole is closed. When the valve core is placed in the body, the valve core is cut into three petals from the urethral hole and the urethral hole, the urethra is placed in the urethral hole, the ureter is placed in the urethral hole, and the valve core is bonded with an adhesive. In this way, the valve core can be installed without damaging the urethra and ureter. The shape, structure and material of the elastic part can be various, such as the material can be rubber, plastic, or even metal. The shape and structure can be cylindrical, circular thin sheet, triangular thin sheet, where the triangle can also be a Lurocks triangle, etc., which will not affect the implementation of this solution.

[0013] Furthermore, the elastic member is an elastic sheet, which can be customized according to the actual shape of the patient's bladder so as to better fit the outer wall of the bladder.

[0014] Furthermore, the elastic sheet is in the shape of a spherical triangle, and its three corners are respectively fixed on the valve body.

[0015] From the back of the human body, two ureters and one urethral opening can be positioned in a triangle. The elastic sheet can be a triangle or a shape similar to a triangle that wraps the two ureters and one urethral opening, such as a Lurox triangle, or a triangle with three sides that are concave arcs. Compared with circular or other shapes, triangular or triangular elastic sheets can reduce weight, making the overall structure lighter. At the same time, the valve core is designed to be triangular, which can be driven by a smaller force to produce a larger deformation, and the maximum deformation is concentrated at the hole position.

[0016] Furthermore, the driving mechanism includes a transmission rod for applying force to the valve core to drive the valve core to undergo elastic deformation, and a magnetic driving mechanism connected to the other end of the transmission rod for driving the transmission rod to move, and the transmission rod is movably connected to the valve body. One end of the transmission rod is connected to the valve core, and the connection is located between the ureteral hole and the urethral hole. When working, the connection can be pulled and lifted in the direction of the ureteral hole. The transmission rod can be in a variety of shapes, such as a straight lever or a bent lever whose fulcrum is located on the valve body to pry up the connection, or a V-shaped rod located in the direction of movement of the connection to lift the connection, etc., which does not affect the implementation of this solution. The transmission rod can be either fixedly connected to the valve core or movably connected. When movably connected, a through hole can be set on the valve core, and the size of the through hole is larger than the thickness of the transmission rod. The transmission rod passes through the through hole to connect to the valve core.

[0017] Furthermore, the magnetic drive mechanism includes a magnetic conductive block disposed on the other end of the transmission rod, and a permanent magnet located outside the body that can attract the magnetic conductive block to move when it is close to the magnetic conductive block.

[0018] The attraction between the magnetic block and the permanent magnet can make the transmission rod move. Compared with urethral valves that use ultrasonic vaporization drive, wireless energy transmission or batteries that need to be implanted in the body, the use of magnetic drive can significantly simplify internal and external devices and improve practicality. At the same time, it does not require energy storage, has high safety and rapid system response.

[0019] Furthermore, the transmission rod is an annular lever sleeved on the valve body, a through hole for the annular lever to pass through is provided on the side wall of the valve core, the annular lever is located on one side of the valve core and inserted in the through hole, the other side of the annular lever is fixedly connected to the magnetic block, the annular lever is hinged to the valve body, and the hinged part of the annular lever and the valve body is located between the connecting end of the annular lever and the valve core and the connecting end of the annular lever and the magnetic block.

[0020] In the human body structure, the side of the bladder with the urethral opening and ureter is close to the back, while the abdomen facing the front is the position that is convenient for the patient to operate. The valve body and the valve core are both structures covered on the outer wall of the bladder. The use of an annular lever can transmit the movement near the abdomen to the valve core near the back, and the annular lever is sleeved on the bracket, so that the structure of the entire invention is compact and highly integrated, and the parts located in various parts of the body are prevented from falling off or malfunctioning. The hinged part can be closer to the valve core, so that the annular lever is a labor-saving lever.

[0021] Furthermore, the diameter of the through hole is greater than the thickness of the annular lever, and the annular lever is movably connected to the through hole.

[0022] When the transmission rod applies force to the valve core, there is room for relative movement and adjustment between the annular lever and the through hole, thus avoiding unnecessary deformation caused by the direct fixed connection between the annular lever and the valve core. At the same time, since the connection between the annular lever and the valve core passes through the side of the valve core and is located horizontally between the ureteral hole and the urethral hole, the horizontal plane where the connection between the annular lever and the valve core is located is parallel to the line connecting the two ureteral holes, so that the force applied to the valve core is more even.

[0023] Furthermore, a limiting boss is provided on the valve body below the magnetic conductive block.

[0024] The limiting boss can limit the rotation angle of the annular lever around its hinge point, preventing the end of the annular lever connected to the magnetic block from excessively falling, thereby causing the end of the annular lever connected to the valve core to be excessively lifted and damage the ureter.

[0025] Furthermore, the portion of the annular lever located at the valve core is fixedly connected to the inner surface or the outer surface of the valve core, and the connection between the annular lever and the valve core is located between the urethral hole and the ureteral hole.

[0026] The annular lever is laterally fixedly connected to the middle of the valve core, and the line connection is more stable. At the same time, the force applied when the valve core is lifted can be more uniform, ensuring that the urethral hole can be opened and the ureteral hole can be closed.

[0027] Furthermore, the magnetic drive mechanism includes a magnetic conductive block disposed on the other end of the transmission rod, and an external controller for controlling the electromagnet to attract the magnetic conductive block.

[0028] Furthermore, the valve body is made of non-magnetic rigid material, and the valve core is made of rubber. The valve body and valve core should be made of materials with good biocompatibility, low density but sufficient strength to minimize the burden on the human body.

[0029] Furthermore, the valve body is fixed on the pubic bone. The valve body is partially ellipsoidal.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] (1) It can realize the opening and closing linkage of the urethral opening and ureteral opening, simulating the open and closed state of the urethral opening and ureteral opening in the normal human body, which is consistent with the coordinated control mechanism of the human urethra and ureteral sphincter, preventing urine from flowing back from the bladder to the kidneys during urination.

[0032] (2) The use of a sheet-like elastic rubber valve core element to simultaneously control the opening and closing of two ureters and one urethral opening can greatly simplify the structure of the implanted part, while avoiding rigid materials such as magnets or springs directly clamping the urethra and ureters to cause mechanical damage.

[0033] (3) Using a circular lever, a magnetic block and an external permanent magnet to control the opening and closing of two ureters and a urethral opening does not require energy storage, is highly safe and has a rapid system response;

[0034] (4) The structure is simple and has a high degree of integration, which reduces the risk of parts falling off, failure or corrosion and has high reliability.

[0035] (5) When the present invention is implanted in the body, there is no need to open holes in the urethra and ureter, and it is wrapped around the outer wall of the bladder, without causing tissue trauma and urinary system infection. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] Example 1

[0047] like Figures 1 to 4 As shown, a bladder distribution valve includes a valve body 3 coated on the outer wall of the bladder, a valve core 1 arranged on the valve body 3 to keep the ureter normally open and the urethra normally closed, and a driving mechanism capable of changing the state of the valve core 1 to close the ureter and open the urethra.

[0048] When the bladder in a normal human body stores urine, the urethral opening is normally closed and the ureteral opening is normally open; when urinating, the urethral opening is opened and the ureteral opening is closed. In the unactivated state, the valve core 1 makes the ureteral opening normally open and the urethral opening normally closed, replacing the power of the urethral sphincter. When urination is required, the drive mechanism is activated, so that the valve core 1 moves to close the ureter and open the urethral opening, simulating normal urination. After urination is completed, the drive mechanism is closed, and the valve core 1 is reset, returning to the state where the ureter is normally open and the urethral opening is normally closed.

[0049] The ureter in the human body is located above the urethral opening. The valve core 1 can be a rod-shaped or sheet-shaped part or other parts that can move up and down on the valve body 3 without affecting the function. In the unactivated state, the valve core 1 is located below to press the urethral opening closed. When urination is required, the valve core 1 rises under the action of the driving mechanism, opens the urethral opening, and presses the ureter closed. The driving mechanism can be a variety of driving modes, and in this embodiment, it is magnetically driven.

[0050] like Figures 1 to 4 As shown, the valve core 1 is provided with a ureteral hole 7 for the ureter on the bladder to pass through, and a urethral hole 8 for the urethral opening on the bladder to pass through, the ureteral hole 7 is normally open and the urethral hole 8 is normally closed, the connection between the driving mechanism and the valve core 1 is located between the ureteral hole 7 and the urethral hole 8, and the connection between the valve core 1 and the driving mechanism can be lifted toward the ureteral hole 7, and the valve core 1 is an elastic member covering the bladder.

[0051] In the actual structure of the human bladder, the ureter and the urethral opening are both located on the side of the bladder close to the back, the ureter is located on the side of the bladder close to the head and extends toward the head, and the urethral opening is located on the side of the bladder close to the foot and extends toward the foot. The material of the elastic member can be elastic rubber, silicone, etc., and the elastic material has a certain deformation ability. The valve core 1 is coated on the side of the bladder with the ureter and the urethral opening, and a ureteral hole 7 for the ureter to pass through is provided at the ureter, and a urethral hole 8 is provided at the urethral opening. When the elastic member as the valve core 1 is manufactured, the two ureteral holes 7 are circular holes cut out on the elastic sheet, and the urethral hole 8 is a slit cut out for the urethra to pass through, so that the ureter is open in the non-working state and the urethral opening is closed under the squeezing of the urethral hole 8. When it is necessary to work, it is only necessary to pull the part between the ureteral hole 7 and the urethral hole 8 on the valve core 1 toward the ureteral hole 7 through the transmission mechanism. Under the property of the elastic material of the valve core 1 itself, the pulled urethral hole 8 changes from a slit to a hole, and the squeezed ureteral hole 7 is squeezed from a round hole to a flat slit, realizing the transition from the ureteral hole 7 opening and the urethral hole 8 closing to the ureteral hole 7 closing and the urethral hole 8 opening. After urination is completed, the force applied to the valve core 1 is canceled, so that the valve core 1 made of elastic material will return to the original state, that is, the ureteral hole 7 is opened and the urethral hole 8 is closed. When the valve core 1 is placed in the body, the valve core 1 is cut into three petals from the urethral hole 8 and the urethral hole 7, the urethra is placed in the urethral hole 8, the ureter is placed in the urethral hole 7, and the valve core 1 is bonded with an adhesive. In this way, the valve core 1 can be installed without damaging the urethra and ureter.

[0052] like Figures 1 to 4 As shown, the elastic member is an elastic sheet. The elastic sheet can be customized according to the actual shape of the patient's bladder so that it can better fit the outer wall of the bladder.

[0053] like Figures 1 to 4 As shown, the elastic sheet is in the shape of a spherical triangle, and its three corners are fixed on the valve body 3 respectively. Figure 4 As described above, from the back of the human body, two ureters and one urethral opening can form a triangle. In this embodiment, the elastic sheet is in a shape similar to a Lurox triangle. A triangular or quasi-triangular elastic sheet can reduce weight compared to a circular or other shaped elastic sheet, making the overall structure lighter. At the same time, the valve core 1 is designed to be triangular, and a smaller force can be used to drive it to produce a larger deformation, and the maximum deformation is concentrated at the hole position.

[0054] like Figures 1 to 4As shown, the driving mechanism includes a transmission rod for applying force to the valve core 1 to drive the valve core 1 to undergo elastic deformation, and a magnetic driving mechanism connected to the other end of the transmission rod for driving the transmission rod to move, and the transmission rod is movably connected to the valve body 3. One end of the transmission rod is connected to the valve core 1, and the connection is located between the ureteral hole 7 and the urethral hole 8. When working, the connection can be pulled and lifted toward the ureteral hole 7. The transmission rod can be fixedly connected to the valve core 1 or movably connected. This embodiment is a movably connected. A through hole can be set on the valve core 1, the size of the through hole is larger than the thickness of the transmission rod, and the transmission rod passes through the through hole to connect with the valve core 1.

[0055] like Figures 1 to 4 As shown, the magnetic drive mechanism includes a magnetic conductive block 4 disposed on the other end of the transmission rod, and a permanent magnet 5 located outside the body and capable of attracting the magnetic conductive body to move when approaching the magnetic conductive block 4.

[0056] The attraction between the magnetic block 4 and the permanent magnet 5 can make the transmission rod move. Compared with urethral valves that use ultrasonic vaporization drive, wireless energy transmission or batteries that need to be implanted in the body, the use of magnetic drive can significantly simplify the internal and external devices and improve practicality. At the same time, it does not require energy storage, has high safety and rapid system response.

[0057] like Figures 1 to 4 As shown, the transmission rod is an annular lever 2 sleeved on the valve body 3, a through hole for the annular lever 2 to pass through is provided on the side wall of the valve core 1, the annular lever 2 is located on one side of the valve core 1 and inserted in the through hole, the other side of the annular lever 2 is fixedly connected to the magnetic block 4, the annular lever 2 is hinged to the valve body 3, and the hinged portion of the annular lever 2 and the valve body 3 is located between the connecting end of the annular lever and the valve core 1 and the connecting end of the annular lever and the magnetic block 4.

[0058] In the human body structure, the side of the bladder with the urethral opening and ureter is close to the back, while the abdomen facing the front is the position that is easy for the patient to operate. The valve body 3 and the valve core 1 are both structures wrapped around the outer wall of the bladder. The use of the annular lever 2 can transmit the movement near the abdomen to the valve core 1 near the back, and the annular lever 2 is set on the bladder, so that the structure of the entire invention is compact and highly integrated, and the parts set in various parts of the body are prevented from falling off or malfunctioning. The hinged part can be closer to the valve core 1, so that the annular lever 2 is a labor-saving lever.

[0059] like Figures 1 to 4 As shown, the diameter of the through hole is greater than the thickness of the annular lever 2, and the annular lever 2 is movably connected to the through hole.

[0060] When the transmission rod applies force to the valve core 1, there is room for relative movement and adjustment between the annular lever 2 and the through hole, thereby avoiding unnecessary deformation caused by the direct fixed connection between the annular lever 2 and the valve core 1. At the same time, since the connection between the annular lever 2 and the valve core 1 passes through the side of the valve core 1 and is located horizontally between the ureteral hole 7 and the urethral hole 8, the horizontal plane where the connection between the annular lever 2 and the valve core 1 is located is parallel to the line connecting the two ureteral holes 7, so that the force applied to the valve core 1 is more even.

[0061] like Figures 1 to 4 As shown, a limiting boss 9 is provided on the valve body 3 below the magnetic conductive block 4 .

[0062] The limiting boss 9 can limit the rotation angle of the annular lever 2 around its hinge point to prevent the end of the annular lever 2 connected to the magnetic block 4 from excessively falling, thereby causing the end of the annular lever 2 connected to the valve core 1 to be excessively lifted to damage the ureter.

[0063] like Figures 1 to 4 As shown, the portion of the annular lever 2 located at the valve core 1 is fixedly connected to the inner surface or the outer surface of the valve core 1 , and the connection between the annular lever 2 and the valve core 1 is located between the urethral hole 8 and the ureteral hole 7 .

[0064] The annular lever 2 is laterally fixedly connected to the middle of the valve core 1, and the line connection is more stable. At the same time, the force applied when the valve core 1 is lifted can be more uniform, ensuring that the urethral hole 8 can be opened and the ureteral hole 7 can be closed.

[0065] like Figures 1 to 4 As shown, the material of the valve body 3 is a non-magnetic rigid material, and the material of the valve core 1 is rubber. The materials of the valve body 3 and the valve core 1 need to be materials with good biocompatibility, low density but sufficient strength, and minimize the burden on the human body.

[0066] like Figures 1 to 4 As shown, the valve body 3 is fixed on the pubic bone 6. The valve body 3 is partially ellipsoidal.

[0067] The working principle of the present invention is as follows: in the bladder urine storage stage, when the external permanent magnet 5 is not close to the anterior wall of the lower abdomen, the magnetic block 4 does not generate magnetic attraction, the annular lever 2 does not move, the urethral opening remains closed under the elastic restoring force of the valve core 1, the ureteral opening remains open, urine is transported to the bladder through the ureter, and the bladder is gradually filled.

[0068] During the urination stage of the bladder, when the external permanent magnet 5 is placed on the anterior wall of the lower abdomen, the magnetic block 4 generates a magnetic attraction force under the action of the magnetic field and acts on the annular lever 2. The annular lever 2 rotates around the hinge point and transmits the driving force to the valve core 1, driving the valve core 1 to move, open the urethral opening, clamp the ureteral opening to allow the urine in the bladder to be continuously discharged from the urethra and prevent urine reflux at the same time. The limiting boss 9 on the bracket can effectively prevent the annular lever 2 from excessive rotation and damaging the ureter.

[0069] After urination, the external permanent magnet 5 is removed from the anterior wall of the lower abdomen, the magnetic block 4 is not affected by the magnetic attraction force, the annular lever 2 has no driving force, the valve core 1 is reset under the action of its own elastic restoring force, the urethral opening is closed, and the ureteral opening is opened. As long as the patient repeats the above process, he can control the storage and discharge of urine by himself and avoid urine reflux into the kidneys.

[0070] Example 2

[0071] This embodiment is similar to Embodiment 1, except that, in this embodiment, Figure 5 and Figure 6 As shown, the shape of the valve core 1 is a triangle composed of three inwardly concave arcs. Such a structure is lighter as a whole while being able to cover the ureter and the urethra. In this embodiment, the annular lever 2 is fixedly connected to the valve core 1 .

[0072] Example 3

[0073] This embodiment is similar to the embodiment 1, except that, in this embodiment, the magnetic drive mechanism includes a magnetic block 4 provided on the other end of the annular lever 2, an electromagnet provided on the valve body 3, and an external controller for controlling the electromagnet to attract the magnetic block 4. The permanent magnet 5 located outside the body is replaced by the electromagnet and the external controller. When urination is required, the controller controls the electromagnet to be energized to generate magnetism, attracting the magnetic block 4 to move downward, and the annular lever 2 rotates around the hinge point, causing the valve core 1 to deform. After urination, the controller controls the electromagnet to be de-energized, and the valve core 1 and the annular lever 2 are reset.

[0074] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
