Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to a peritoneal dialysis device. Background Technology

[0002] Existing peritoneal dialysis fluid packaging bags suffer from leakage problems. The root cause is that the welding points of the packaging bags are not completely sealed, leading to leakage and even dialysis fluid contamination, which seriously affects safety. Furthermore, traditional dialysis equipment packaging requires wrapping and binding the infusion tubing to reduce packaging space. In particular, the infusion tubing at the connection between the dialysis bag and the infusion tubing is twisted and deformed, causing the tubing to fold and stick to the inner wall. During dialysis, the dialysis fluid cannot flow normally, rendering the entire dialysis equipment unusable. To solve these problems, a peritoneal dialysis device has been designed. Utility Model Content

[0003] This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, one objective of this invention is to propose a peritoneal dialysis device that solves the problems of leakage and adhesion of the inner wall of the infusion tubing.

[0004] The peritoneal dialysis device proposed according to this utility model includes a V-shaped connector, which is composed of a steering rubber head, a first fitting end, and a second fitting end, with the first fitting end and the second fitting end respectively arranged at both ends of the steering rubber head.

[0005] The steering rubber head is made of polycarbonate, and the first and second fitting ends are arranged at an obtuse angle.

[0006] A connecting straight pipe is fitted onto the surface of the first end of the assembly;

[0007] The surface of the second fitting end is fitted with an infusion tube. The first fitting end, the second fitting end, and the infusion tube are all made of polycarbonate particles. The second fitting end and the infusion tube are connected by a solvent.

[0008] Preferably, the angle between the first end of the kit and the second end of the kit is in the range of 100°-145°.

[0009] Preferably, the system further includes a seamless polypropylene bag and a drainage bag. The opening of the seamless polypropylene bag is fixed with a combined cap, and the connecting straight tube is fitted over the surface of the combined cap. The opening of the drainage bag is fixed with a connecting short tube, and a drainage tube is fitted and fixed on the surface of the connecting short tube. The drainage tube and the infusion tube are connected by a T-joint. In addition to connecting with the drainage tube and the infusion tube, the T-joint is also provided with a connecting connector.

[0010] Preferably, the seamless polypropylene bag is integrally molded.

[0011] Preferably, a connector protective cap is threaded onto the surface of the connector.

[0012] Preferably, the interior of the combined cover is provided with a break rod, and the connecting straight tube is fitted onto the surface of the break rod.

[0013] Preferably, the connecting straight tube and the broken rod are bonded together with alcohol.

[0014] The beneficial effects of this utility model are:

[0015] 1. To solve the leakage problem, since the seamless polypropylene bag is made with a one-piece molding process, the possibility of leakage is extremely low except for the welding of the combined cap.

[0016] 2. To solve the problem of inner wall adhesion caused by twisting and winding of infusion tubing during packaging, a V-shaped connector is used to replace the excessively twisted part of the original infusion tubing, allowing the infusion tubing to transition smoothly during packaging without bending, thus solving the problem of inner wall adhesion of the infusion tubing.

[0020] Reference Figure 1-2 The peritoneal dialysis device includes a V-shaped connector 9, which is an integral structure. The V-shaped connector 9 consists of a steering rubber head 91, a first fitting end 92, and a second fitting end 93. The first fitting end 92 and the second fitting end 93 are respectively arranged at both ends of the steering rubber head 91.

[0021] The steering head 91 is made of polycarbonate, and the first fitting end 92 and the second fitting end 93 are arranged at an obtuse angle.

[0022] The first set of end 92 is fitted with a connecting straight pipe 8;

[0023] The surface of the second fitting end 93 is fitted with an infusion tube 3. The first fitting end 92, the second fitting end 93 and the infusion tube 3 are all made of polycarbonate. The second fitting end 93 and the infusion tube 3 are connected by a solvent, which is alcohol.

[0024] The angle between the first fitting end 92 and the second fitting end 93 is in the range of 100°-145°, for reference. Figure 1 In this embodiment, the first fitting end 92 and the second fitting end 93 are arranged at a 120° angle.

[0025] The peritoneal dialysis device also includes a seamless polypropylene bag 11 and a drainage bag 1. The opening of the seamless polypropylene bag 11 is fixed with a combination cap 10. A connecting straight tube 8 is fitted onto the surface of the combination cap 10. The opening of the drainage bag 1 is fixed with a connecting short tube 7. A drainage tube 2 is fitted onto the surface of the connecting short tube 7. The drainage tube 2 and the infusion tube 3 are connected by a tee fitting 4. In addition to connecting with the drainage tube 2 and the infusion tube 3, the tee fitting 4 is also equipped with a connecting connector 5.

[0026] Seamless polypropylene bag 11 One-piece molding.

[0027] The surface of the connector 5 is threaded with a connector protective cap 6.

[0028] The interior of the combination cover 10 is equipped with a break rod, which can also be called a break valve or a break plug. It is a conventional structure, and the connecting straight pipe 8 is fitted onto the surface of the break rod.

[0029] The straight tube 8 and the broken rod are bonded together with alcohol.

[0030] During packaging, the infusion tube 3 is directly wrapped and contained. A V-shaped connector 9 is used to transition at the connection between the infusion tube 3 and the seamless polypropylene bag 11, so that the infusion tube 3 is less likely to be bent and stuck at the connection with the seamless polypropylene bag 11 during containment. During subsequent storage, the inner wall of the connection between the infusion tube 3 and the seamless polypropylene bag 11 is less likely to stick and block.
