Description

Technical Field

[0001] This utility model relates to a medical auxiliary material, specifically, to a disposable sterile urinary catheterization kit. Background Technology

[0002] Disposable sterile catheterization kits are key consumables in clinical catheterization procedures, and their design directly affects patient safety and ease of operation. This is a sterile medical product integrating multiple components, specifically designed for catheterization. Currently, there are many catheterization products on the market. For example, Chinese patent CN223490151U discloses a catheterization kit with a drainage structure, including a catheter component and an adjustment component. The catheter component includes a shell, a catheter tube, a drain tube, a retaining ring, and an insertion hole. The top of the shell connects to the catheter tube, the bottom of the shell connects to the drain tube, and the bottom side of the drain tube connects to the catheter tube. A retaining ring is provided at the top of the drain tube's inner lumen, and an insertion hole is opened at the center of the bottom of the drain tube. The adjustment component is connected to the drain tube and includes a push rod, a piston, and a spring. The push rod is inserted into the insertion hole, and the top of the push rod has a piston that fits into the inner wall of the retaining ring. A spring is provided between the piston and the bottom of the drain tube's inner lumen. However, the push rod needs to be pushed up and down during use. During this process, the push rod may pull the sealing ring in the insertion hole out of the insertion hole, affecting the sealing effect. Moreover, the spring structure makes the catheterization kit more expensive as a disposable product and it is also easy to break.

[0003] Chinese patent CN223569723U discloses a urinary catheter drainage bag, which drains urine by adjusting the plug structure. However, the plug structure design requires pulling the plug outward to close the drainage bag and pushing the plug inward to open it. The plug itself lacks protection, so when the drainage bag is closed, the plug is easily pushed into the open state by accident. When it is necessary to stop draining urine from the urinary catheter drainage bag, the urinary catheter drainage bag needs to be made of rigid material, which is bulky, costly, and inconvenient for packaging and transportation. If the drainage bag is made of flexible material, it is inconvenient to exert force when pulling the plug to close the urinary catheter drainage bag, and the distance of pulling the plug is difficult to control, which can easily cause the plug to fall out completely.

[0004] In order to solve the above problems, people have been seeking an ideal technological solution. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a disposable sterile urinary catheterization kit.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A disposable sterile urinary catheterization kit includes a urinary catheter and a drainage bag that cooperates with the urinary catheter. The drainage bag includes a flexible body with an inlet at the top and a outlet at the bottom. The inlet is connected to a short inlet tube that cooperates with the urinary catheter. The outlet has a short outlet tube with an adjusting seat in the middle. The adjusting seat is horizontally positioned and has an installation groove inside. A limiting ring is provided at the open end of the installation groove, and an adjusting column is provided inside the installation groove. The outer diameter of the adjusting column is related to the inner diameter of the installation groove. The inner diameter of the limiting ring is smaller than the outer diameter of the adjusting column. One end of the adjusting column is connected to the operating block via a connecting rod. The connecting rod passes through the limiting ring and extends out of the mounting groove. The adjusting seat is provided with a first drainage through hole, and the adjusting column is provided with a corresponding second drainage through hole. The first drainage through hole is coaxial with and connected to the drainage short pipe. The inner end of the adjusting column abuts against the sealing end of the mounting groove. The projections of the second drainage through hole and the first drainage through hole on the horizontal plane do not overlap. The outer end of the adjusting column abuts against the limiting ring of the mounting groove. The second drainage through hole is coaxial with the first drainage through hole.

[0007] The inner wall of the limit ring is provided with internal threads, and the outer wall of the connecting rod is provided with external threads. The connecting rod is threadedly connected to the limit ring.

[0008] The flexible body is equipped with lifting rings on both sides of the liquid inlet, and the end of the liquid inlet short tube is equipped with a tapered constriction.

[0009] The flexible body surface is printed with volume scale lines.

[0010] The flexible body is rectangular near the inlet, and gradually narrows into an arc shape near the outlet, with the arc shape smoothly transitioning to the bottom of the flexible body.

[0011] An auxiliary rigid plate is connected to the curved side, and the auxiliary rigid plate smoothly transitions with the flexible body to form a rectangular outline.

[0012] The auxiliary rigid plate and the operating block are located on both sides of the adjustment seat, and the edge of the operating block is evenly provided with several anti-slip protrusions. Compared to existing technologies, the advantages of this invention are as follows: This invention provides a disposable sterile urinary catheterization kit with a simple and reasonable structure. Through the cooperation of a flexible main body, auxiliary rigid plate, adjusting seat, and adjusting column, it not only minimizes the adverse effects of bumps and knocks but also reduces production costs and facilitates packaging and transportation. Specifically, the inner end of the adjusting column abuts against the sealing end of the mounting groove, and the projections of the second drainage hole and the first drainage hole on the horizontal plane do not overlap, meaning the drainage port of the drainage bag is in a closed state. The outer end of the adjusting column abuts against the limiting ring of the mounting groove, and the second drainage hole is coaxial with the first drainage hole, ensuring the drainage port of the drainage bag is in an open state, facilitating the discharge of urine from the drainage bag.
