Description

Technical Field

[0001] This invention relates to the field of urinary catheterization technology, and more specifically to a urinary catheterization device for patient care. Background Technology

[0002] A urinary catheter is a medical device used to drain urine from the bladder. It is mainly used when a patient is unable to urinate independently and is a very common nursing and treatment method in clinical practice. A standard urinary catheter usually includes: a catheter, a drainage tube, a urine collection bag, and accessories. Common materials for the catheter include silicone, latex, and polyethylene. Silicone has good biocompatibility and is suitable for long-term indwelling. Indwelling catheters are the most common type. They have a water-filled balloon at the front end. After being inserted into the bladder, sterile water is injected to inflate the balloon, thereby fixing it in the bladder and preventing it from falling out. However, existing catheterization devices have some drawbacks, such as: The diameter of the urinary catheter is fixed. In some patients whose urethra is more sensitive or fragile, a urinary catheter with a larger diameter is difficult to insert or causes discomfort to the patient during insertion. Therefore, the existing urinary catheters cannot be thinned during insertion and return to their original shape after insertion, which is inconvenient to use.

[0003] Therefore, the present invention provides a urinary catheterization device for patient care to solve the above-mentioned problems. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a urinary catheterization device for patient care, which solves the problem that the existing urinary catheters cannot shrink during insertion and return to their original shape after insertion.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A urinary catheterization device for patient care includes an elastic lubricating membrane, a silicone tube, an inner lining membrane, and a highly elastic membrane; Silicone tubing: An installation ring is fixedly connected to one end of the silicone tubing, and a urine catheter head is fixedly connected to the other end of the installation ring. A water balloon is fixedly fitted over the urine catheter head. The sides of the silicone tubing are provided with notches and extension holes in a circular and linear array. High-elasticity membrane: The high-elasticity membrane is fixedly attached to the inside of the silicone tube. The high-elasticity membrane is pleated and forms an outer channel in a circular array with the silicone tube. An inner pusher strip is inserted laterally in the outer channel. When the water bladder inflates, it pushes the inner pusher strip to move laterally. The side of the inner pusher strip is provided with a linear array of latex protrusions and connecting posts. The latex protrusions are laterally aligned with the notch. The connecting posts move through the extension hole. An outer pusher strip is fixedly connected between a row of connecting posts. Elastic lubricating membrane: The elastic lubricating membrane is wrapped around an outer pusher strip. The elasticity of the elastic lubricating membrane is less than that of the high elasticity membrane. Inner membrane: The inner membrane is attached and fixed inside the high elastic membrane. The end of the inner membrane is fixedly connected to the side of the mounting ring. The high elastic membrane is pleated and forms water channels in a circular array with the inner membrane. The water channels are connected to the water bladder. Through the above technical solution, the elastic lubricating membrane, silicone tube, inner lining membrane, and highly elastic membrane can all be flexibly deformed to allow the device to be inserted into the urethra. During insertion, the silicone tube presses against the latex protrusion, causing one inner pusher to retract into the silicone tube and one outer pusher to move closer to the silicone tube. This reduces the diameter of the outer pusher and the diameter of the elastic lubricating membrane, making insertion into the urethra easier and reducing irritation. After insertion, water is supplied to the water-filled balloon through the channel between the inner lining membrane and the highly elastic membrane, causing the balloon to inflate. This, on the one hand, allows... The water balloon and catheter head are fixed inside the bladder. On the other hand, the water balloon can push the inner pusher strip to move laterally, so that the latex protrusion can be inserted into the notch. The loss of the latex protrusion's support, the elasticity of the elastic lubricating membrane being less than that of the high elastic membrane, and the increase in water pressure in the water channel are the three technical effects that make the high elastic membrane push the inner pusher strip. The outer pusher strip moves away from the silicone tube, increasing the diameter of the outer pusher strip and the diameter of the elastic lubricating membrane, which is more conducive to fixing it inside the urethra. In addition, the increased diameter of the inner membrane increases the speed of urine discharge from the bladder.

[0006] Preferably, the silicone tube is externally fixed to an inner bladder, and a connecting hole is provided between the silicone tube and the high elastic membrane. The connecting hole is located inside the waterway and is connected to the inner bladder. An adhesive block is attached to the side of the inner bladder. A transverse tube is fixedly connected between the outer push strips. The transverse tube is located outside the inner bladder. When the inner bladder expands, the adhesive block pushes the transverse tube to move laterally. With the above technical solution, when the water pressure in the waterway increases, the inner bladder will bulge. The inner bladder pushes the transverse tube to move laterally through the adhesive block. The transverse tube pulls the outer push bar to move laterally. That is, the water bladder pushes the inner push bar and the transverse tube pulls the outer push bar. The pushing and pulling forces act on the inner push bar and the outer push bar at the same time, increasing the transverse force of the inner push bar and the outer push bar.

[0007] Preferably, the length of the silicone tube is longer than that of the elastic lubricating membrane, and a water supply component is installed at the end of the silicone tube outside the elastic lubricating membrane, the water supply component supplying water into the waterway; The water supply assembly includes an external connecting pipe, an inlet pipe, a water injection hole, and a sealing block. The inlet pipe is fixedly sleeved on the outside of the silicone tube. The external connecting pipe is fixedly connected to the side of the inlet pipe. The silicone tube has a circular array of water injection holes on its side. The water injection holes are located inside the inlet pipe. A sealing block is fixedly connected inside the water channel. The sealing block blocks the water channel. The water injection holes are located between the sealing block and the water bladder. The inner bladder is located between the water injection holes and the water bladder. Through the above technical solution, the water supply component is used to deliver water into the waterway, which increases the pressure of the water bladder, waterway and inner bladder, thereby causing the water bladder and inner bladder to expand, while the sealing block seals the end of the waterway to ensure the waterway is sealed inside.

[0008] Preferably, the water bladder has a water inlet on its side and a water outlet inside the mounting ring. A connecting hose is fixedly connected between the water inlet and the water outlet, and the water outlet is aligned with the water channel. Through the above technical solution, the water channel is connected to the water bladder through the water outlet, the connecting hose, and the water inlet. The connecting hose is a flexible pipe that can be deformed, ensuring that the water channel and the water bladder are always connected when the water bladder expands and contracts.

[0009] Preferably, the mounting ring has an integrally formed inner support edge on the side near the elastic lubricating membrane, and the end of the elastic lubricating membrane that is sleeved outside the inner support edge forms a soft sleeve pleated edge, which is movably sleeved outside the inner support edge. Through the above technical solution, when the elastic lubricating film moves laterally along with the outer pusher, the soft sleeve pleated edge can be straightened or pleated to adapt to the movement of the elastic softening film.

[0010] Preferably, a patch is attached to the side of the water bag near the inner push strip, and the patch presses against the inner push strip; Through the above technical solution, the patch reduces the impact force of the inner push strip on the water bladder, thus protecting the water bladder.

[0011] The beneficial effects of this invention are as follows: The elastic lubricating membrane, silicone tube, inner lining membrane, and highly elastic membrane can all be flexible and deformable to allow the device to be inserted into the urethra and adapt to the curvature of the urethra. When inserted, the silicone tube presses against the latex protrusion, causing the inner pusher to retract into the silicone tube and the outer pusher to move closer to the silicone tube. This reduces the diameter of the outer pusher and the diameter of the elastic lubricating membrane, making them thinner and easier to insert into the urethra, reducing irritation to the urethra and improving patient comfort. After insertion, water is pumped into the balloon through the water channel between the inner lining and the high-elasticity membrane, causing the balloon to inflate. This inflates the balloon and the catheter head, securing them in the bladder. Additionally, the balloon pushes the inner pusher laterally, causing the latex protrusion to engage with the notch. The loss of the latex protrusion's support, the lower elasticity of the elastic lubricating membrane compared to the high-elasticity membrane, and the increased water pressure within the water channel all contribute to the high-elasticity membrane pushing the inner pusher. This causes the outer pusher to move further away from the silicone tube, increasing the diameter of both the outer pusher and the elastic lubricating membrane, making it easier to secure the balloon within the urethra. Furthermore, the increased diameter of the inner lining increases the rate of urine expulsion from the bladder. In summary, this device can be inserted into the urethra and adapts to the curvature of the urethra. It reduces the overall diameter during insertion, making it easier to insert into the urethra, reducing irritation, and improving comfort. After insertion, it is fixed and the overall diameter is restored, facilitating urination. Attached Figure Description

[0024] The following will refer to the attached reference. Figures 1 to 11 The various embodiments of the present invention will be described in detail below. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0025] As attached Figure 1 - Appendix Figure 11 As shown, a urinary catheterization device for patient care includes an elastic lubricating membrane 3, a silicone tube 5, an inner lining membrane 8, and a highly elastic membrane 10. Silicone tube 5: See appendix Figure 7 One end of the silicone tube 5 is fixedly connected to an installation ring 17, and the other side of the installation ring 17 is fixedly connected to a urinary catheter head 1. After the urinary catheter head 1 is inserted into the bladder, it is used to receive urine. A water balloon 2 is fixedly sleeved on the outside of the urinary catheter head 1. The water balloon 2 does not expand under normal conditions and is tightly attached to the outside of the urinary catheter head 1. When the water balloon 2 is in normal conditions, its diameter is equal to or smaller than the diameter of the urinary catheter head 1. The water balloon 2 begins to expand after water is injected into it. See appendix Figure 8 The other end of the silicone tube 5 is fixedly connected to an inner bladder 20, which is located inside the transverse tube 4. The transverse tube 4 is laterally movably sleeved outside the silicone tube 5. A connecting hole 28 is provided on the side of the silicone tube 5, which is located inside the inner bladder 20. An adhesive block 21 is attached to the side of the inner bladder 20. When the inner bladder 20 expands, the adhesive block 21 pushes the transverse tube 4 to move laterally. See appendix Figure 11 The silicone tube 5 has notches 26 and extension holes 27 arranged in a circular and linear array on its side. High-elasticity membrane 10: See appendix Figure 3 Appendix Figure 4 and attached Figure 11 A highly elastic membrane 10 is fixedly attached to the inside of a silicone tube 5. The highly elastic membrane 10 is pleated and forms an outer channel in a circular array with the silicone tube 5. An inner pusher strip 11 is laterally inserted and moved within the outer channel. A patch 24 is attached and fixed to the side of the water bladder 2 near the inner pusher strip 11. When the water bladder 2 expands, the patch 24 presses against the inner pusher strip 11 and pushes the inner pusher strip 11 to move laterally. The side of the inner pusher strip 11 is provided with a linear array of latex protrusions 25 and connecting posts 12. The latex protrusions 25 are laterally aligned with the notch 26. The connecting posts 12 move through the extension hole 27. An outer pusher strip 13 is fixedly connected between a row of connecting posts 12. (See attached diagram) Figure 8 The transverse tube 4 is fixedly connected between the outer push bars 13. When the transverse tube 4 moves laterally, it pulls the outer push bars 13. Elastic lubricating film 3: See appendix Figure 3 and attached Figure 4 The elastic lubricating membrane 3 is fitted around the outer pusher strip 13. The elasticity of the elastic lubricating membrane 3 is less than that of the high-elasticity membrane 10. (See appendix) Figure 7 The mounting ring 17 has an integrally formed inner support edge 18 on the side near the elastic lubricating membrane 3. The end of the elastic lubricating membrane 3 that is sleeved outside the inner support edge 18 forms a soft sleeve pleated edge 19, which is movably sleeved outside the inner support edge 18. Inner lining 8: See Appendix Figure 3 and attached Figure 4The inner liner 8 is attached and fixed inside the high-elasticity membrane 10. Urine flows through the inner liner 8. The end of the inner liner 8 is fixedly connected to the side of the mounting ring 17. The high-elasticity membrane 10 is pleated and forms water channels 9 in a circular array with the inner liner 8. (See attached diagram) Figure 7 The water bladder 2 has a water inlet 14 on its side and a water outlet 16 inside the mounting ring 17. A connecting hose 15 is fixedly connected between the water inlet 14 and the water outlet 16. The water outlet 16 is aligned with the water channel 9, so that the water channel 9 connects to the water bladder 2. (See attached diagram) Figure 8 Furthermore, a connecting hole 28 is provided at the same position on the side of the high elastic membrane 10 and the side of the silicone tube 5, so that the connecting hole 28 on the side of the high elastic membrane 10 and the side of the silicone tube 5 are aligned and connected to each other, and the connecting hole 28 is located in the water channel 9.

[0026] In this embodiment, the length of the silicone tube 5 is longer than that of the elastic lubricating membrane 3, and a water supply component is installed at the end of the silicone tube 5 located outside the elastic lubricating membrane 3. The water supply component delivers water into the water channel 9. See appendix Figure 9 The water supply assembly includes an external connecting pipe 7, an inlet pipe 6, a water injection hole 22, and a sealing block 23. The inlet pipe 6 is fixedly sleeved on the outside of the silicone tube 5. The side of the inlet pipe 6 is fixedly connected to the external connecting pipe 7. The side of the silicone tube 5 is provided with a circular array of water injection holes 22, which are located inside the inlet pipe 6. The sealing block 23 is fixedly connected inside the water channel 9, blocking the water channel 9. The water injection hole 22 is located between the sealing block 23 and the water bladder 2, and the inner bladder 20 is located between the water injection hole 22 and the water bladder 2.

[0027] The working principle of this device is as follows: During insertion: the catheter head 1, water balloon 2 and installation ring 17 are sequentially inserted into the urethra. Then, the elastic lubricating membrane 3, silicone tube 5, inner lining membrane 8 and high elastic membrane 10 are inserted into the urethra. During insertion, the silicone tube 5 presses against the latex protrusion 25, causing the inner push strip 11 to retract into the silicone tube 5. The inner push strip 11 drives the outer push strip 13 to approach the silicone tube 5 through the connecting post 12, thus reducing the diameter of the outer push strip 13 and the diameter of the elastic lubricating membrane 3. After insertion: the water supply assembly delivers water from the water channel between the inner membrane 8 and the high elastic membrane 10 to the water bladder 2 and the inner bladder 20, causing the water bladder 2 and the inner bladder 20 to bulge. The water bladder 2 pushes the inner push bar 11 to move laterally. The inner bladder 20 pushes the transverse tube 4 through the adhesive block 21. The transverse tube 4 pulls the outer push bar 13, causing the inner push bar 11 and the outer push bar 13 to move laterally together. After the movement, the latex protrusion 25 is inserted into the notch 26. The high elastic membrane 10 pushes the inner push bar 11, and the outer push bar 13 moves away from the silicone tube 5, increasing the diameter of the outer push bar 13 and the diameter of the elastic lubricating membrane 3. After use, drain the water, the water bladder 2 and inner bladder 20 will retract, and the device can be pulled out.
