Catheter connecting device

Abstract

The invention provides a catheter connecting device. The catheter connecting device comprises a near-end connector, a far-end connector and two groups of cross-section connecting tubes, wherein the near-end connector and the far-end connector are rotatably connected together, each of the ends, far away from each other, of the near-end connector and the far-end connector is provided with one group of cross-section connecting tubes, a group of tube cavity channels is uniformly arranged inside the near-end connector along the rotation direction, at least one group of tube cavity channels is correspondingly arranged inside the far-end connector along the rotation direction, the near-end connector or the far-end connector is rotated, the tube cavity channels of the near-end connector, the tube cavity channels of the far-end connector and the cross-section connecting tubes communicate with each other, and thus the conversion of the flowing directions of fluid in the tube cavity channels is realized. With the catheter connecting device, the conversion of the flowing directions of the fluid can be rapidly and effectively realized.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a catheter connection device with two ends respectively connected to a single (multiple) lumen catheter and a tail pipe. Background technique [0002] Known human body implantable catheters are cylindrical, flexible medical devices used for the extraction and introduction of fluids (gas, liquid) in patient body cavities, tubes, veins, etc., such as intravenous indwelling (including PICC), hemodialysis , Airway intubation, gastric tube intubation, bladder intubation, serosal cavity intubation, etc. [0003] A multilumen catheter (usually double or triple lumen) can introduce and withdraw fluid in one direction, or introduce and withdraw fluid simultaneously. The openings of the multi-cavities inserted into the lumen of the human body are in parallel or upstream and downstream positions, while the distal ends are mostly in parallel positions; the apertures of the multi-cavities ar...

AI Technical Summary

Problems solved by technology

[0008] 4. The diameters of each chamber of the multi-lumen catheter are different, resulting in different maximum flow rates; for example: in the process of rescue of severe shock with large and small PICC catheters, different types of drugs are introduced into each of the two lumens

[0009] Through the search, the Chinese invention patent of "The First People's Hospital of Yichang City" with the application number "201220047744.5" was retrieved, which disclosed "a medical multifunctional conversion joint", which is a hollow shuttle-shaped body with open ends. The outer casing of the shuttle body is an annular stepped structure, which is used to solve the connection of catheters of different specifications, and cannot solve the technical problems mentioned in the background technology
