Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a urinary catheterization device for bladder rehabilitation training in patients with diabetes and heart failure. Background Technology

[0002] There are two types of urinary catheterization devices: one is a long-term indwelling catheterization device, and the other is an intermittent catheterization device, which is used for short periods of time each time the patient needs to urinate, in order to help the patient with bladder training.

[0003] Current urinary catheters are often inserted into the urethra using pre-lubricated lubricant. However, when the catheter encounters obstruction in the urethra, or when the lubricant at the catheter tip is squeezed and scraped by the urethral wall, its lubrication effect decreases, causing severe discomfort for the patient, especially those undergoing bladder training. Secondly, the tip of existing catheters is located in the middle of the balloon. When the balloon inflates, the fluid level at the catheter inlet rises, preventing the inlet from contacting residual urine in the bladder. This results in insufficient and incomplete urine drainage, easily leading to urinary system problems and further impacting the patient's health. Furthermore, due to the composition of urine, the catheter inlet is prone to blockage. Summary of the Invention

[0004] One objective of this invention is to reduce discomfort for patients using urinary catheterization devices.

[0005] Another objective of this invention is to improve the degree of urine emptying in patients.

[0006] Specifically, the present invention provides a urinary catheterization device for bladder rehabilitation training in patients with diabetes and heart failure, comprising: a urinary catheter, a lubricating balloon, and a pressure balloon; the lubricating balloon is disposed at the top of the urinary catheter and is filled with lubricating fluid; a lubricating tube is disposed on the lubricating balloon, the lubricating tube extending to the periphery of the urinary catheter for supplying lubricating fluid to the periphery of the urinary catheter; the pressure balloon is disposed on the urinary catheter and abuts against the lubricating tube; the pressure balloon is configured such that, during the insertion of the urinary catheter into the urethra, the pressure inside the balloon is adjusted to cause the pressure balloon to expand or contract, thereby blocking or opening the lubricating tube.

[0007] Furthermore, the catheterization device for bladder rehabilitation training in patients with diabetes and heart failure also includes: a balloon, which is fitted onto the catheter; the balloon is configured to inflate after being moved to the bladder to prevent the catheter from falling out.

[0008] Furthermore, the catheterization device for bladder rehabilitation training in patients with diabetes and heart failure also includes: a fluid inlet tube connected to the balloon for infusing or draining fluid from the balloon, causing the balloon to inflate or deflate.

[0009] Furthermore, the top of the catheter is provided with a movable head, the bottom of which is engaged with the catheter; the bottom of the movable head is provided with a flexible tube that connects to the catheter, and the side wall of the flexible tube is provided with a urinary inlet; the movable head is configured to disengage from the catheter after moving to the bladder and hang down under the action of gravity, thereby causing the flexible tube to extend out of the catheter.

[0010] Furthermore, a pressure balloon is positioned on the moving head and abuts against the wall of the catheter; the pressure balloon is configured to inflate after being moved to the bladder, pushing the moving head away from the catheter.

[0011] Furthermore, the tubing has multiple urine inlets spaced apart.

[0012] Furthermore, the catheterization device for bladder rehabilitation training in diabetic patients with heart failure also includes: a pressure tube connected to a pressure balloon for adjusting the pressure inside the balloon; part of the pressure tube is located inside the tubing and catheter, and part is fixedly inserted into the wall of the catheter; wherein, the part of the pressure tube located inside the tubing and catheter has redundancy, and after the tubing extends out of the catheter, it swings and turbulents with the impact of urine.

[0013] Furthermore, the pressure bladder and the moving head are molded as a single unit.

[0014] Furthermore, the lubrication bladder is annular and located inside the moving head, with multiple lubrication tubes spaced circumferentially; the pressure bladder is also annular and simultaneously controls the opening and closing of multiple lubrication tubes.

[0015] Furthermore, the elastic modulus of the pressure bladder wall is greater than that of the lubrication tube wall.

[0016] The beneficial effects of this invention are:

[0017] The urinary catheterization device for bladder rehabilitation training in diabetic patients with heart failure of the present invention, by setting a lubrication balloon and a pressure balloon at the tip of the urinary catheter, allows the pressure balloon to control the opening and closing of the lubrication tube when the urinary catheter moves in the urethra, thereby supplying lubricating fluid to the tip of the urinary catheter at any time, thereby reducing the resistance encountered by the urinary catheter when moving in the urethra and reducing the patient's discomfort.

[0018] Furthermore, the bladder rehabilitation training catheterization device for diabetic patients with heart failure of the present invention, by setting a movable head that is snapped into the catheter, and after the movable head moves to the bladder, the movable head is disengaged from the snap and hangs down naturally, causing the tubing to extend out of the catheter and hang down, thereby reducing the liquid level at the inlet of the tubing and improving the degree of emptying of the patient's urine.

[0019] Furthermore, in the bladder rehabilitation training device for diabetic patients with heart failure of the present invention, the pressure tube portion connecting the pressure balloon is placed inside the tubing and the catheter, and a redundancy is reserved so that after the tubing extends out of the catheter, the pressure tube can swing and turbulent under the impact of urine, thereby reducing the risk of blockage at the urinary inlet.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art should be able to understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0033] The following reference Figures 1 to 7 This invention describes a catheterization device for bladder rehabilitation training in patients with diabetes and heart failure.

[0034] This embodiment provides a catheterization device for bladder rehabilitation training in patients with diabetes and heart failure. The catheterization device for bladder rehabilitation training in patients with diabetes and heart failure generally includes: a catheter 100, a lubrication balloon 200, and a pressure balloon 300.

[0035] A lubricating balloon 200 is located at the top of the catheter 100 and is filled with lubricating fluid. A lubricating tube 210 is provided on the lubricating balloon 200, extending to the outer periphery of the catheter 100, for supplying lubricating fluid to the outer periphery of the catheter 100. A pressure balloon 300 is located on the catheter 100 and abuts against the lubricating tube 210. The pressure balloon 300 is configured such that, during insertion of the catheter 100 into the urethra, adjusting the pressure within the balloon causes it to expand or contract, thereby blocking or opening the lubricating tube 210.

[0036] The lubrication bladder 200 is made of elastic material and is inflated due to the lubricating fluid inside. Before the catheter 100 is inserted into the patient's urethra, the pressure bladder 300 maintains a high pressure, and the inflated state of the pressure bladder 300 compresses the lubrication tube 210, thus sealing the lubrication tube 210.

[0037] During the insertion of the catheter 100 into the urethra, if the patient experiences discomfort, the pressure within the pressure balloon 300 is reduced, causing the balloon to shrink and releasing the pressure on the lubrication tube 210, thus restoring its patency. Once the lubrication tube 210 is unobstructed, lubricating fluid, under the elastic force of the lubrication balloon 200, flows through the lubrication tube 210 to the outer periphery of the catheter 100, lubricating it and reducing patient discomfort during insertion. After the patient's discomfort decreases, the pressure within the pressure balloon 300 can be increased to restore pressure on the lubrication tube 210, re-sealing it.

[0038] After the patient finishes urinating, lubricant can still be supplied during the removal of catheter 100, based on the patient's sensation, to reduce discomfort. During catheter insertion and removal, the operator can supply lubricant multiple times based on the patient's sensation to minimize discomfort.

[0039] In this embodiment, by setting a lubrication balloon 200 and a pressure balloon 300 at the tip of the catheter 100, the pressure balloon 300 can control the opening and closing of the lubrication tube 210 when the catheter 100 moves in the urethra, thereby supplying lubricating fluid to the tip of the catheter 100 at any time, thereby reducing the resistance encountered by the catheter 100 when moving in the urethra, greatly reducing the patient's discomfort, and assisting diabetic patients with heart failure to better carry out bladder rehabilitation training.

[0040] Preferably, the lubricant is sterile saline solution, which is not only low in cost and easy to obtain, but also will not cause adverse reactions such as allergies in patients.

[0041] Catheterization devices for bladder rehabilitation training in patients with diabetes and heart failure may generally include a balloon 400.

[0042] A balloon 400 is attached to the urinary catheter 100. The balloon 400 is configured to inflate upon movement to the bladder, preventing the urinary catheter 100 from dislodging.

[0043] In this embodiment, by placing a balloon 400 on the urinary catheter 100 and inflating the balloon 400 after it moves to the bladder, the urinary catheter 100 is prevented from falling out, thereby ensuring that the urinary catheter 100 will not fall out accidentally due to changes in the patient's body position, and allowing urine to be continuously, stably and smoothly discharged from the body through the urinary catheter 100.

[0044] In order to inflate the balloon 400, in some embodiments, the catheterization device for bladder rehabilitation training in patients with diabetes and heart failure may also generally include a fluid inlet tube 410. The fluid inlet tube 410 is connected to the balloon 400 and is used to inflate or deflat the balloon 400 by introducing or removing fluid from the balloon 400.

[0045] In this embodiment, by setting up a fluid inlet tube 410, the balloon 400 is inflated or contracted by inputting or outputting fluid. This not only makes the operation simple, but also allows for more intuitive and controllable expansion or contraction of the balloon 400 by observing the volume of the input or output fluid.

[0046] Preferably, the end of the infusion tube 410 extending from the catheter 100 can be connected to a syringe, allowing fluid to be injected into or withdrawn from the infusion tube 410 by operating the syringe. The fluid introduced into the balloon 400 by the infusion tube 410 is sterile saline, which is inexpensive and readily available. Figure 4 As shown, the fluid inlet tube 410 can be installed in the wall of the catheter 100, making the structure more stable.

[0047] In order to inflate the balloon 400, in some other embodiments, the balloon 400 may be connected to a dedicated inflation device, which inflates or deflates the balloon 400 by injecting or depressing gas into the balloon 400.

[0048] The catheter 100 has a movable head 500 at its top, and the bottom of the movable head 500 is engaged with the catheter 100. A flexible tube 510 communicating with the catheter 100 is located at the bottom end of the movable head 500, and a urinary inlet 511 is provided on the side wall of the flexible tube 510. The movable head 500 is configured such that, after moving to the bladder, it disengages from the catheter 100 and hangs down under gravity, causing the flexible tube 510 to extend out of the catheter 100.

[0049] In this embodiment, a movable head 500 is attached to the catheter 100. After the movable head 500 moves to the bladder, it disengages and hangs down naturally, causing the tubing 510 to extend out of the catheter 100 and hang down. This lowers the liquid level at the inlet 511 of the tubing 510, thereby improving the patient's urinary emptying rate. This improved urinary emptying rate not only reduces the risk of urinary tract infections but also lowers bladder pressure, preventing urine reflux and damage to the kidneys, thus protecting kidney function. Furthermore, it allows the bladder to undergo normal expansion and contraction exercises, maintaining its good functional state and improving the rehabilitation training effect for patients with diabetes and heart failure.

[0050] Preferably, the catheter 100 and the flexible tube 510 can be made of a flexible material (e.g., silicone). The diameter of the flexible tube 510 is smaller than the diameter of the catheter 100, and the wall thickness of the flexible tube 510 is smaller than the wall thickness of the catheter 100. In the initial state before the catheter 100 is inserted, the maximum radial dimension of the moving head 500 is smaller than the outer diameter of the catheter 100.

[0051] In some embodiments, to disengage the movable head 500 from the catheter 100, a pressure balloon 300 is disposed on the movable head 500 and abuts against the wall of the catheter 100. The pressure balloon 300 is configured to inflate upon movement into the bladder, pushing the movable head 500 out of the catheter 100.

[0052] like Figure 5 As shown, the movable head 500 is generally mushroom-shaped and consists of two parts, upper and lower. The upper part of the movable head 500 is nearly hemispherical and protrudes radially beyond the lower part. The pressure balloon 300 is located in the protruding area of ​​the upper part of the movable head 500. A retaining ring 520 protrudes radially outward at the bottom end of the movable head 500, and the protrusion of the retaining ring 520 is smaller than that of the upper part of the movable head. The end of the catheter 100 is held between the retaining ring 520 and the pressure balloon 300. One end of the tubing 510 is fixed to the inner wall of the catheter 100, and the other end is fixed to the bottom end of the movable head 500. When the end of the catheter 100 retracts radially inward and is held between the retaining ring 520 and the pressure balloon 300, the outer wall of the catheter 100 abuts against the pressure balloon 300, and the inner wall of the catheter 100 abuts against the retaining ring 520.

[0053] When the pressure balloon 300 inflates, it pushes against the outer wall of the catheter 100, causing the movable head 500 to move upward relative to the catheter 100. As the movable head 500 moves upward, it also causes the retaining ring 520 to move upward synchronously. The upward movement of the retaining ring 520 expands the end wall of the catheter 100. As the degree of inflation of the pressure balloon 300 increases, the upward distance of the movable head 500 relative to the catheter 100 increases, and the upward distance of the retaining ring 520 gradually exceeds the height of the lower half of the movable head, thus completely disengaging the movable head 500 from the catheter 100.

[0054] In this embodiment, by adjusting the pressure inside the pressure balloon 300, the pressure balloon 300 is further expanded. This pressure balloon 300 then pushes against the wall of the catheter 100, causing the moving head 500 to disengage from the catheter 100. This design is not only simple in structure but also easy to operate. Simultaneously, the further expansion of the pressure balloon 300 increases the squeezing force on the lubrication tube 210, ensuring that the lubrication tube 210 remains blocked within the bladder.

[0055] In order to disengage the movable head 500 from the catheter 100, in some embodiments, an inflatable balloon can be provided at the end of the catheter 100, and the expansion of the balloon can be used to push the movable head 500 out of the catheter 100.

[0056] The tubing 510 has multiple urine inlets 511 spaced apart.

[0057] In this embodiment, by providing multiple urine inlets 511 at intervals on the flexible tube 510, the urine discharge becomes smoother, improving the urine discharge efficiency and reducing the risk of blockage.

[0058] A catheterization device for bladder rehabilitation training in patients with diabetes and heart failure may generally also include a pressure tube 310. The pressure tube 310 is connected to a pressure balloon 300 and is used to regulate the pressure within the balloon 300. Part of the pressure tube 310 is located inside the tubing 510 and the catheter 100, and part is fixedly inserted into the wall of the catheter 100. The portion of the pressure tube 310 located inside the tubing 510 and the catheter 100 has redundancy, allowing it to oscillate and turbulent with the impact of urine flow after the tubing 510 extends out of the catheter 100.

[0059] In this embodiment, the pressure tube 310 is partially placed inside the hose 510 and the catheter 100, with a redundancy allowance. This allows the pressure tube 310 to swing and turbulent under the impact of urine after the hose 510 extends out of the catheter 100, thereby reducing the risk of blockage of the urine inlet 511.

[0060] Preferably, the end of the pressure tube 310 extending from the catheter 100 can be connected to a syringe. Liquid (e.g., sterile saline) is injected into the pressure tube 310 by operating the syringe to control the pressure within the pressure balloon 300. This method is not only low-cost and readily available, but also allows for more direct and controllable observation of the injected or withdrawn liquid volume via the syringe, making the expansion or contraction of the pressure balloon 300 more intuitive and manageable. Furthermore, after the movable head 500 disengages from the catheter 100, the liquid filling the pressure balloon 300 can assist the movable head 500 in descending more effectively, preventing it from floating upwards within the bladder.

[0061] The pressure bladder 300 and the moving head 500 are integrally molded.

[0062] In this embodiment, the pressure bladder 300 and the moving head 500 are integrally molded, thereby improving structural stability, reducing the risk of the pressure bladder 300 becoming misaligned or even falling off the moving head 500 due to repeated expansion and contraction, and improving reliability and durability.

[0063] The lubrication bladder 200 is annular and disposed within the moving head 500, and has multiple lubrication tubes 210 spaced circumferentially. The pressure bladder 300 is also annular and controls the opening and closing of the multiple lubrication tubes 210.

[0064] In this embodiment, the lubrication bladder 200 is configured as a ring, and multiple lubrication tubes 210 are spaced apart around the circumference of the lubrication bladder 200, so that the supply of lubricating fluid is more comprehensive and further reduces patient discomfort. Preferably, the multiple lubrication tubes 210 can be evenly distributed around the circumference of the lubrication bladder 200.

[0065] like Figure 5 As shown, in some embodiments, the moving head 500 may be provided with an annular cavity, in which the lubrication bladder 200 is disposed, thereby avoiding direct contact between the lubrication bladder 200 and the urethra, ensuring that the supply of lubricating fluid is not interfered with by the compression of the urethra, and is more stable and reliable.

[0066] The elastic modulus of the pressure bladder 300 wall is greater than that of the lubrication tube 210 wall.

[0067] In this embodiment, the elastic coefficient of the pressure balloon 300 wall is set to be greater than that of the lubrication tube 210 wall. This allows the pressure balloon 300 to expand only slightly, enabling its wall to withstand the pressure of the lubrication balloon 200, deforming the lubrication tube 210 and causing it to become blocked. This avoids excessive expansion of the pressure balloon 300 in the urethra, which could cause patient discomfort.

[0068] The catheterization device for bladder rehabilitation training in diabetic patients with heart failure provided in this embodiment is a disposable device to reduce the risk of infection for patients.

[0069] The specific working process of the bladder rehabilitation training catheter device for diabetic patients with heart failure provided by the present invention will be described in conjunction with the above embodiments:

[0070] Before inserting the catheter 100 into the patient's urethra, lubricant can be applied to the periphery of the catheter 100. At this time, the balloon 400 is in a contracted state. The pressure balloon 300 presses against the lubrication tube 210, and the lubrication tube 210 is in a blocked state.

[0071] After the catheter 100 is inserted into the urethra and begins to move, the expansion and contraction of the pressure balloon 300 are controlled according to the patient's sensation. When the patient feels discomfort, fluid is withdrawn from the pressure balloon 300 through the pressure tube 310, causing the pressure balloon 300 to contract. After the pressure balloon 300 contracts, the lubrication tube 210 becomes unobstructed, and the lubricating fluid in the lubrication balloon 200 is discharged through the lubrication tube 210, flowing to the outer periphery of the moving block. As the catheter 100 moves, the lubricating fluid adheres to the outer periphery of the catheter 100, thereby reducing the patient's discomfort. After the patient's discomfort subsides, fluid is injected into the pressure balloon 300 through the pressure tube 310, causing the pressure balloon 300 to expand, thereby squeezing the lubrication tube 210 and restoring its occlusion.

[0072] Before the end of the catheter 100 reaches the bladder, the operator can control the pressure balloon 300 multiple times according to the patient's sensation to supply lubricating fluid. Simultaneously, the operator can also actively supply lubricating fluid based on the insertion depth of the catheter 100.

[0073] After the end of the catheter 100 is moved to the bladder, fluid is injected into the balloon 400 through the infusion tube, causing the balloon 400 to inflate within the bladder and thus preventing the catheter 100 from dislodging. Then, fluid is injected into the pressure balloon 300 through the pressure tube 310, further inflating the balloon and pushing against the wall of the catheter 100, causing the moving head 500 to disengage from the catheter 100. After the moving head 500 disengages from the catheter 100, it hangs down under gravity, causing the tubing 510 to extend out of the catheter 100 and hang down. After the tubing 510 extends out of the catheter 100, urine from the bladder enters the tubing 510 through the inlet 511 and then flows out through the catheter 100.

[0074] After the patient's urine is emptied, the fluid in balloon 400 is aspirated through the infusion tube, causing balloon 400 to return to its contracted state. Then, some fluid is aspirated from pressure balloon 300 through pressure tube 310, causing pressure balloon 300 to shrink while maintaining the blockage of lubrication tube 210. The operator then removes catheter 100. During this process, the operator can still adjust the release of lubricating fluid from pressure balloon 300 based on the patient's comfort to reduce discomfort.

[0075] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0076] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
