Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a medical dilation and drainage device. Background Technology

[0002] A urinary catheter is a tube inserted into the bladder through the urethra to drain urine. When a patient is unable to urinate normally due to various reasons (such as benign prostatic hyperplasia, urethral stricture, neurogenic bladder, etc.), causing urinary retention, a urinary catheter can be inserted into the bladder to drain the urine, quickly relieving the patient's discomfort symptoms such as bladder fullness and pain, and avoiding serious consequences such as bladder overdistension leading to bladder dysfunction or even bladder rupture.

[0003] In existing technologies, urinary catheters are prone to internal blockage due to various reasons during use. For example, insufficient water intake by patients reduces urine production and concentrates urine, increasing the concentration of various formed elements and increasing the possibility of crystal formation and flocculent material production, thus blocking the urinary catheter. Furthermore, when the concentration of substances such as calcium, oxalic acid, and uric acid in the patient's urine is too high, these substances may precipitate and form crystals inside the urinary catheter, gradually accumulating and causing blockage. To address these issues, existing urinary catheters need to be improved to prevent blockage and unusability during use. Therefore, this device provides a medical dilation and drainage device. Utility Model Content

[0004] The purpose of this invention is to provide a medical dilation and drainage device to address the shortcomings of existing technologies and solve the aforementioned technical problems.

[0005] This utility model embodiment adopts the following technical solution: a medical dilation and drainage device, including a urinary catheter, which consists of a tube body, an outlet tube, an injection tube, and an injection balloon; the injection tube is located at the first end of the tube body, the outlet tube is located at the oblique side of the injection tube, and a urine collection bag is connected to the outlet tube to collect the urine flowing out of the urinary catheter; the injection balloon is located at the end of the tube body; a guide wire for clearing blockages is provided inside the tube body, the guide wire is movable within the tube body, one end of the guide wire is located inside the tube body, and the other end of the guide wire extends to the outside of the tube body through the injection tube. This application solves the problem in the prior art where urinary catheters are easily blocked by foreign objects in the urine during drainage.

[0006] Furthermore, a thickened tube is provided on the side of the tube near the water injection bladder. The thickened tube increases the diameter of the tube, which facilitates the placement of the blockage removal component.

[0007] Furthermore, two symmetrical slots are formed on the inner sides of both the water injection pipe and the pipe body, and the water injection pipe is connected to the slots in the pipe body. Each slot is used for the guide wire to slide within the water injection pipe and the pipe body. The slots in the pipe body prevent the guide wire from moving freely within the pipe body, and the slots limit the movement of the guide wire.

[0008] Furthermore, the catheter is made of rubber. Rubber catheters possess excellent flexibility and elasticity, allowing them to conform to the physiological curvature of the urethra when inserted.

[0009] Furthermore, a pull wire is connected to one end of each of the two guidewires located outside the tube body. The pull wire, connected to the two guidewires outside the tube body, facilitates pulling by medical personnel.

[0010] Furthermore, the blockage removal component is composed of circular wires, cloth, and needles. The circular wires are located inside the thickened tube on the tube body. The cloth is arranged around the circular wires on the outside of the circular wires. Multiple needles are provided, and the multiple needles are evenly distributed on the inside of the circular wires.

[0011] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0012] In this invention, a guide wire structure is designed inside the catheter body. A blockage-clearing component is installed inside the guide wire within the catheter body. The guide wire drives the blockage-clearing component to move within the catheter body, allowing the guide wire to accurately deliver the blockage-clearing component to the blockage site. The blockage-clearing component directly acts on the blockage, more effectively removing crystals, flocculent matter, and other blockages, restoring the catheter's patency. Compared to traditional flushing methods, the cleaning effect is more significant. Timely removal of blockages from the catheter prevents it from becoming a breeding ground for bacteria, reducing the chance of bacterial proliferation within the catheter and thus lowering the incidence of urinary tract infections. This method solves the problem in existing technologies where catheters are easily blocked by foreign objects in urine during drainage. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] The following is in conjunction with the appendix Figure 1-5 This document provides a detailed description of the technical solutions provided in each embodiment of the present invention.

[0023] This utility model embodiment provides a medical dilation and drainage device, including a urinary catheter 1, which is composed of a tube body 11, a urine outlet tube 12, a water inlet tube 13, and a water inlet balloon 14. The water inlet tube 13 is located at the first end of the tube body 11, and the urine outlet tube 12 is located at the oblique side of the water inlet tube 13. A urine collection bag 121 is connected to the urine outlet tube 12 to collect the urine flowing out of the urinary catheter 1. The water inlet balloon 14 is located at the end of the tube body 11. A guide wire 2 for clearing blockages is provided inside the tube body 11. The guide wire 2 is movably located in the tube body 11, with one end of the guide wire 2 located inside the tube body 11 and the other end of the guide wire 2 extending to the outside of the tube body 11 through the water inlet tube 13.

[0024] This application designs a structure to prevent blockage of the urinary catheter 1. In existing urinary catheters 1, the drain tube 12 is used to drain fluid in conjunction with the catheter body 11, the water-filled balloon 14 is used to fix the catheter body 11 to the patient, and the water-filled tube 13 is used to inject water into the water-filled balloon 14 to inflate it. This application also designs a guide wire 2 structure inside the catheter body 11. The guide wire 2 has a blockage-clearing component 21 inside the catheter body 11. The guide wire 2 is used to move the blockage-clearing component 21 within the catheter body 11, thus allowing the guide wire 2 to more accurately remove blockages. The blockage removal component 21 is delivered to the blockage site, and its direct action on the blockage material can more effectively remove blockage materials such as crystals and flocculents, restoring the patency of the catheter 1. Compared with traditional flushing methods, the cleaning effect is more significant. Timely removal of blockage materials in the catheter 1 can prevent the blockage material from becoming a breeding ground for bacteria, reducing the chance of bacteria multiplying in large quantities in the catheter 1, thereby reducing the incidence of urinary tract infections. In this way, the problem of the catheter 1 being easily blocked by foreign objects in urine during drainage in the existing technology can be solved.

[0025] In a further preferred embodiment of this invention, a thickened tube 111 is provided on the side of the tube body 11 near the water-filled balloon 14. The thickened tube 111 increases the diameter of the tube body 11 at a certain point, which facilitates the placement of the blockage removal component 21. This ensures that the blockage removal component 21 does not affect the normal drainage of the tube body 11 when it is not in use. Placing the thickened tube 111 next to the water-filled balloon 14 facilitates the insertion of the tube body 11 into the patient's body. Since the water-filled balloon 14 itself is slightly wider in diameter than the tube body 11, placing the thickened tube 111 next to it will not affect the normal use of the tube body 11.

[0026] In a further preferred embodiment of this utility model, two slots 131 are symmetrically provided on the inner sides of the water injection pipe 13 and the pipe body 11, and the water injection pipe 13 is connected to the slots 131 in the pipe body 11. Each slot 131 is used for the guide wire 2 to slide inside the water injection pipe 13 and the pipe body 11. In this application, setting the slots 131 in the pipe body 11 to place the guide wire 2 can prevent the guide wire 2 from moving freely in the pipe body 11. The slots 131 can limit the guide wire 2, so that the guide wire 2 can drive the blockage cleaning component 21 to slide in the pipe body 11, while the guide wire 2 itself will not affect the normal drainage of the pipe body 11.

[0027] In a further preferred embodiment of this invention, the urinary catheter 1 is made of rubber. The rubber urinary catheter 1 possesses excellent flexibility and elasticity, allowing it to conform to the physiological curvature of the urethra when inserted, reducing damage to the urethral mucosa and minimizing patient discomfort during catheterization. Furthermore, the rubber urinary catheter 1 better adapts to the morphological changes of the human urethra, fitting tightly against the urethral wall. This ensures smooth urine drainage while effectively preventing leakage, thus improving the effectiveness and comfort of catheterization.

[0028] In a further preferred embodiment of this invention, a pull wire 22 is connected to one end of each of the two guide wires 2 located outside the tube body 11. The connection of the pull wire 22 to the two guide wires 2 outside the tube body 11 facilitates pulling by medical personnel. The connection between the pull wire 22 and the two guide wires 2 forms a hook-shaped space that facilitates pulling. Medical personnel can simultaneously move the two guide wires 2 synchronously within the tube body 11 by pulling the pull wire 22, thus ensuring smoother movement of the blockage removal component 21.

[0029] In a further preferred embodiment of this utility model, the blockage removal component 21 is composed of a circular wire 211, a cloth 212, and needles 213. The circular wire 211 is located inside the thickened tube 111 provided on the tube body 11. The cloth 212 is arranged around the circular wire 211 on its outer side. Multiple needles 213 are provided, and the multiple needles 213 are evenly distributed on the inner side of the circular wire 211. The circular guide wire 2 can be flexibly moved within the catheter 1 by the pull of the guide wire 2, which can accurately reach the blockage site, so that the needles 213 can accurately act on the blockage, avoiding damage to the catheter 1 and urethra due to blind operation, and improving the cleaning efficiency; the cloth 212 has a certain degree of adsorption and friction. When the circular guidewire 2 with fabric 212 moves inside the catheter 1, the fabric 212 can absorb fibrous material, crystals, and other blockages within the catheter 1. Simultaneously, through friction with the blockages, larger blockages are broken down into smaller particles, facilitating their removal with urine. This effectively clears the blockages from the catheter 1, restoring its patency. Compared to rigid cleaning tools, the fabric 212 is soft. During the clearing process, it reduces damage to the inner wall of the catheter 1 and the urethral mucosa, lowering the likelihood of complications such as catheter rupture, urethral bleeding, or pain caused by the cleaning procedure, thus better protecting the integrity of the urinary system. Since catheter blockages are often caused by crystals, blood clots, and fibrous material, the needle 213 can directly puncture and break these blockages into smaller pieces, facilitating their removal with urine or flushing fluid, effectively restoring the patency of the catheter 1, especially effective against stubborn crystals and large blood clots.

[0030] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
