Abstract

The invention provides a central vein catheter, and relates to the technical field of medical apparatus and instruments. The central vein catheter comprises a main catheter body, at least one branch pipe and at least one extension pipe; the main catheter body is internally provided with at least one passage extending in the axial direction of the passage; the outlet end of any one branch pipe is communicated with the corresponding passage, and the inlet end of any one branch pipe is communicated with the corresponding extension pipe; a sub connector is arranged at the inlet end of each branchpipe, and an outer connector cooperating with the corresponding sub connector is arranged at the inlet end of each extension pipe; the sub connectors and the outer connectors are adjusted, and the branch pipes and the extension pipes are conducted or blocked or separated. According to the central vein catheter, conduction and blocking of the central vein catheter are achieved by means of the sub connectors and the outer connectors, a traditional stop clamp is replaced, breakage risk of the central vein catheter can be eradicated, the probability of medical negligence is lowered, and the service life of the medical apparatus and instruments is prolonged.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a central venous catheter. Background technique [0002] The central venous catheter is an important channel for intraoperative and postoperative monitoring, fluid replacement and blood transfusion, and infusion of various rescue drugs for critically ill patients. Intensive Care Unit (ICU) hospitalized patients need long-term transfusion, transfusion of blood products, intravenous nutrition therapy and other peripheral repeated venipuncture inevitably cause pain to patients. In addition, drugs and hypertonic fluids may cause damage to blood vessels. Peripheral vascular puncture is difficult, and a central venous catheter is a better choice at this time. [0003] Central venous catheters generally include the following four types: percutaneous central venous catheter (CVC), peripherally punctured central catheter (PICC), tunneled central venous catheter (CVTC) and venous ...
