Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a fluid pressure amplifying and conducting device for improving urine control function. Background Art

[0002] There is a certain amount of pressure in some organs and cavities in the body, such as abdominal pressure, bladder pressure, rectal pressure, urethral pressure, etc. In some pathological conditions, increased abdominal pressure may lead to some disease states, such as stress urinary incontinence.

[0003] For stress urinary incontinence, treatments generally include behavioral therapy, medication, and surgery.

[0004] Behavioral therapy mainly involves exercising the pelvic floor muscles and ligaments, but the effects are slow and uncertain.

[0005] The efficacy of drug treatment for mild to moderate patients can reach 50% to 60%, but the treatment effect on moderate to severe patients is poor and the side effects are obvious.

[0006] Surgery is the main treatment for stress urinary incontinence. At present, conventional surgical methods usually involve implanting a sling or artificial urinary sphincter, but there are the following defects: 1. Blind implantation of a sling can easily cause physical damage, such as bladder perforation or peripheral vascular damage, and vaginal damage; 2. Because the sleeve or sling will exert lasting pressure on the urethral tissue, affecting the blood circulation of the urethral tissue, and then causing urethral atrophy, leading to recurrence of urinary incontinence; 3. The structure of the artificial urinary sphincter is complex and cannot be adjusted once implanted, resulting in a high risk of failure. Summary of the invention

[0007] The purpose of the present invention is to provide a fluid pressure amplification and transmission device for improving urinary control function in response to the existing technical status. The device can amplify the increase in abdominal pressure during the patient's stress period accompanied by the increase in pressure of the first balloon and transmit it to the second balloon in the urethral tissue, thereby increasing the patient's urethral pressure and achieving the effect of improving urinary control function.

[0008] In order to achieve the above object, the present invention adopts the following technical scheme:

[0009] A fluid pressure amplifying and conducting device for improving urine control function, comprising a first balloon, a second balloon, a first connecting tube and a second connecting tube;

[0010] The first balloon and the second balloon are both elastic;

[0011] The inner diameter of the first connecting pipe is greater than the inner diameter of the second connecting pipe;

[0012] The first connecting tube and the second connecting tube are both connected between the first balloon and the second balloon, and the first balloon, the second balloon, the first connecting tube and the second connecting tube are filled with fluid;

[0013] The first connecting pipe is connected with a first one-way valve, and the flow direction of the first one-way valve is from the first balloon to the second balloon;

[0014] The second connecting pipe is connected with a second one-way valve, and the flow direction of the second one-way valve is from the second balloon to the first balloon.

[0015] Furthermore, the volume of the first balloon is greater than the volume of the second balloon.

[0016] Furthermore, the volume ratio of the first balloon to the second balloon is 2-10.

[0017] Furthermore, the diameter ratio of the first connecting pipe to the second connecting pipe is 2-20.

[0018] Furthermore, the fluid is liquid.

[0019] Furthermore, the liquid is water.

[0020] Furthermore, the wall thickness of the first balloon is smaller than the wall thickness of the second balloon.

[0021] Furthermore, the first balloon and the second balloon are both made of rubber material.

[0022] Furthermore, the first connecting pipe and the second connecting pipe are both made of PVC material.

[0023] The beneficial effects of the present invention are:

[0024] 1. The present invention provides a fluid pressure amplification and transmission device for improving urine control function. After a first balloon and a second balloon are respectively implanted into the abdominal wall tissue gap and urethral tissue of a patient, the increased abdominal pressure of the patient during the stress period accompanied by the increased pressure of the first balloon can be amplified and transmitted to the second balloon in the urethral tissue, thereby increasing the urethral pressure of the patient and achieving the effect of improving urine control function.

[0025] 2. The present invention provides a fluid pressure amplification and conduction device for improving urine control function, which is to implant the balloon into body tissue under direct vision, thereby ensuring positioning accuracy and avoiding the risk of blind penetration causing damage to the bladder, vagina or surrounding large blood vessels and other tissues and organs;

[0026] 3. The present invention provides a fluid pressure amplification and transmission device for improving urine control function. The balloon in the urethra is in a non-expanded state when the abdominal pressure is not increased, thereby preventing damage to blood vessels around the urethra due to long-term compression, and even causing urethral atrophy;

[0027] 4. The present invention provides a fluid pressure amplification and conduction device for improving urine control function, which is only composed of a balloon, a connecting tube and a one-way valve. Different from the existing artificial urethral sphincter, its structure is simpler and can prevent the failure of complex mechanical parts. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and implementation examples. It should be understood that the specific examples described herein are only used to explain the present invention and are not used to limit the present invention.

[0039] See also Figure 1 As shown, a fluid pressure amplifying and conducting device for improving urine control function includes a first balloon 1, a second balloon 2, a first connecting tube 3 and a second connecting tube 5.

[0040] The first balloon 1 and the second balloon 2 are both made of elastic bodies, and the volume of the first balloon 1 is greater than the volume of the second balloon 2 .

[0041] Specifically, the first balloon 1 and the second balloon 2 are both made of rubber material, and the volume ratio of the first balloon 1 to the second balloon 2 is 2-10.

[0042] Exemplarily, in this embodiment, the volume ratio of the first balloon 1 to the second balloon 2 is 5.

[0043] The inner diameter of the first connecting pipe 3 is greater than the inner diameter of the second connecting pipe 5 .

[0044] Specifically, the first connecting pipe 3 and the second connecting pipe 5 are both non-collapsible pipes, for example, made of PVC (polyvinyl chloride) material, and the diameter ratio of the first connecting pipe 3 to the second connecting pipe 5 is 2-20.

[0045] Exemplarily, in this embodiment, the diameter ratio of the first connecting tube 3 to the second connecting tube 5 is 10.

[0046] The first connecting tube 3 and the second connecting tube 5 are both connected between the first balloon 1 and the second balloon 2 , and the first balloon 1 , the second balloon 2 , and the first connecting tube 3 and the second connecting tube 5 are filled with fluid.

[0047] Specifically, the fluid is liquid. The first balloon 1, the second balloon 2, the first connecting tube 3 and the second connecting tube 5 should be kept airtight and free of bubbles.

[0048] Exemplarily, in this embodiment, the liquid is water.

[0049] The first connecting tube 3 is connected with a first one-way valve 4 , and the flow direction of the first one-way valve 4 is from the first balloon 1 to the second balloon 2 , that is, in the first connecting tube 3 , the fluid can only flow along the first balloon 1 to the second balloon 2 .

[0050] The second connecting tube 5 is connected with a second one-way valve 6 , and the flow direction of the second one-way valve 6 is from the second balloon 2 to the first balloon 1 , that is, in the second connecting tube 5 , the fluid can only flow along the second balloon 2 to the first balloon 1 .

[0051] According to the above technical solution, after the first balloon 1 and the second balloon 2 are implanted in the patient's abdominal wall tissue gap and urethral tissue respectively, the increased abdominal pressure during the patient's stress period can be amplified along with the increased pressure of the first balloon and transmitted to the second balloon in the urethral tissue, so that the patient's urethral pressure is increased, thereby achieving the effect of improving urinary control function. When the patient recovers from the stress period to the rest period, the pressure of the second balloon can be reduced to or close to the physiological level, avoiding persistent compression of the urethral tissue, thereby preventing urethral tissue atrophy.

[0052] As an application, the present invention can be used to eliminate urinary incontinence caused by increased abdominal pressure in patients, or to control urination in patients with urinary diversion.

[0053] See also Figures 1-2 As shown, the mechanism of action of the fluid pressure amplification and conduction device is as follows:

[0054] When the patient's abdominal pressure increases, it acts on the first balloon 1 (the first balloon 1 will be squeezed) and on the fluid in the first balloon 1. The fluid in the first balloon 1 is transferred to the second balloon 2 via the first connecting tube 3 in one direction, acts on the second balloon 2 (the second balloon 2 will expand), and acts on the tissue outside the second balloon 2, thereby increasing the patient's urethral pressure. At the same time, a small amount of fluid in the second balloon 2 is transferred to the first balloon 1 via the second connecting tube 5 in one direction.

[0055] As the patient's abdominal pressure rises, the excess fluid in the second balloon 2 is transferred to the first balloon 1 through the second connecting tube 5 in one direction, and both the first balloon 1 and the second balloon 2 return to their initial states.

[0056] The patient's increased abdominal pressure is generally due to coughing, bending over, etc.

[0057] Among them, the volume of the first balloon 1 is greater than that of the second balloon 2, which is more conducive to storing sufficient fluid in the first balloon 1. After being squeezed, the fluid enters the second balloon 2, so as to better realize the fluid pressure amplification and transmission between the first balloon 1 and the second balloon 2; the inner diameter of the first connecting tube 3 is greater than the inner diameter of the second connecting tube 5, so that when the patient's abdominal pressure increases due to coughing or other phenomena, the speed at which the fluid in the first balloon 1 enters the second balloon 2 is faster than the speed at which the fluid returns from the second balloon 2 to the first balloon 1, so as to better realize the fluid pressure amplification and transmission between the first balloon 1 and the second balloon 2.

[0058] In some other embodiments, the wall thickness of the first balloon 1 is smaller than that of the second balloon 2 , which is more conducive to the squeezing of the first balloon 1 and the expansion of the second balloon 2 , so as to better achieve the fluid pressure amplification and transmission between the first balloon 1 and the second balloon 2 .

[0059] See also Figures 3 to 5 As shown, the surgical procedure for implanting the fluid pressure amplification and conduction device into the body is as follows:

[0060] The urethral adventitia and smooth muscle layer are cut open at the high-pressure end of the urethra, and the second balloon 2 is placed in the urethral mucosal tissue with rich vascular sinuses between the urethral smooth muscle and the urethral mucosal layer, and then the above incision is sutured;

[0061] The first balloon 1 is placed in any gap of the abdominal wall tissue, for example, within the abdominal wall muscle, or between the peritoneum and the abdominal wall muscle, or between the rectus abdominis muscle and the anterior rectus abdominis sheath.

[0062] It should be noted that there are a large number of vascular sinus tissues with special morphology in the submucosal layer of the urethral high-pressure area. Therefore, placing the second balloon 2 in the urethral submucosal layer between the urethral muscle layer and the urethral mucosal layer is more in line with physiological conditions and has a bionic effect. The first balloon 1 can also be placed in the abdominal cavity, but it needs to be fixed by suturing.

[0063] The following introduces some test results of the fluid pressure amplification and transmission device:

[0064] See also Figure 6 As shown, the abscissa represents time, the ordinate represents fluid pressure, the blue curve represents the fluid pressure in the first balloon, and the red curve represents the fluid pressure in the second balloon (the same below). When the first balloon 1 and the second balloon 2 have the same volume, and there is no first check valve 4 on the first connecting tube 3 and no second check valve 6 on the second connecting tube 5, when the fluid pressure in the first balloon 1 changes, the fluid pressure in the second balloon 2 changes accordingly, and the pressure amplification conduction factor is about 1.46;

[0065] See also Figure 7As shown, when the volume ratio of the first balloon 1 to the volume ratio of the second balloon 2 is 5, and there is no first check valve 4 on the first connecting tube 3 and no second check valve 6 on the second connecting tube 5, when the fluid pressure in the first balloon 1 changes, the fluid pressure in the second balloon 2 changes accordingly, and the pressure amplification conduction factor is about 2.19;

[0066] See also Figure 8 As shown, the first balloon 1 and the second balloon 2 have the same volume, and the first connecting tube 3 is connected to the first one-way valve 4, and the second connecting tube 5 is connected to the second one-way valve 6. When the fluid pressure in the first balloon 1 changes, the fluid pressure in the second balloon 2 changes accordingly, and the pressure amplification conduction factor is about 2.81;

[0067] See also Fig. 9 As shown, the ratio of the volume of the first balloon 1 to the volume of the second balloon 2 is 5, and the first connecting tube 3 is connected to the first one-way valve 4 and the second connecting tube 5 is connected to the second one-way valve 6, when the fluid pressure in the first balloon 1 changes, the fluid pressure in the second balloon 2 changes accordingly, and the pressure amplification conduction factor is about 6.5.

[0068] It can be seen from the experimental results that whether there is a one-way valve on the first connecting tube 3 and the second connecting tube 5 has a great influence on the amplifying and conducting effect of the fluid pressure amplifying and conducting device; whether the volume of the first balloon 1 is greater than the volume of the second balloon 2 has a great influence on the amplifying and conducting effect of the fluid pressure amplifying and conducting device.

[0069] The present invention is not limited to the above-mentioned specific implementation modes. A person skilled in the art can implement the present invention in various other specific implementation modes based on the contents disclosed in the present invention. Therefore, any design that adopts the design structure and concept of the present invention and makes some simple changes or modifications shall fall within the scope of protection of the present invention.
