Anti-reverse flow combinable extension tube

Abstract

The invention discloses an anti-reflux combinable extension tube, which relates to the technical field of extension tubes and includes a tube body, one end of which is fixedly installed with an elliptical outlet, and a three-way valve channel is opened inside the elliptical outlet. Invented the anti-reflux combinable extension tube, through the arrangement of the tube body and the block, the anti-reflux combinable extension tube has the effect of preventing pipeline confusion, twisting and liquid reflux, through the three-way valve channel Cooperating with the feeding tube, it can pass through the card slot on one side of the tube during use, and there must be a ‑cm gap between the blocks. When using more than two tubes, you only need to clamp the tube in the groove The internal fixation is proper, so that the tubes are connected in parallel. When the catheter is removed, it is only necessary to separate the catheter from the groove, and add a diaphragm inside the joint. It is designed according to the principle of the three-way valve, which is convenient to use and easy to install. , to achieve the purpose of preventing backflow and pipeline confusion.

Description

technical field [0001] The invention relates to the technical field of extension pipes, in particular to an anti-reverse flow combinable extension pipe. Background technique [0002] Medical catheters are generally slender tubes made of plastic or rubber. Medical catheters are usually matched with other medical components to make infusion sets, urinary catheters, heparin tubes, etc. Before use, industrial medical catheters need to be various as needed. The tube body cooperates, and the catheter is prone to disorder, distortion, and reflux of the drug during the cooperation process. In order to reduce bacterial infection and speed up the efficiency of tube delivery, extension tubes are generally used to assist treatment. [0003] Due to diseases, multiple extension tubes need to be used to pump a variety of drugs at the same time, and due to the increase of pipelines, the catheters will be messy, the pipelines will be knotted and twisted, and the separation will be difficult....

AI Technical Summary

Problems solved by technology

[0003] Due to the disease, it is necessary to use multiple extension tubes to pump multiple drugs at the same time, and due to the increase of pipelines, the catheters will be messy, the pipelines will be knotted and twisted, and it will not be easy to separate. , blood reflux, which increases the chance of infection, so it is necessary to solve the problem of confusion, twisting and liquid reflux of multiple groups of medication pipelines, and it is convenient to adjust the number of catheters at any time to combine and separate at any time. Anti-reflux combinable extension tube, and the existing extension tube is limited in rotation angle and insufficient in expansion capacity, which cannot meet the needs of different occasions. Therefore, an anti-backflow combinable extension tube is urgently needed to solve the above problems
