Description

Extracorporeal Catheter Fixation and Protection Device for Disposable Central Venous Catheters

technical field

The utility model belongs to the technical field of medical devices, in particular to a disposable central venous catheter external catheter fixing and protecting device.

Background technique

The central venous infusion catheter is an important medical method clinically used for drug infusion, rescuing patients, and treating diseases. Because of the need for long-term treatment of various diseases, various central venous catheters are also indwelled for a long time (ranging from 7 days to 1 year). During the period, various complications related to infusion catheters may occur, among which catheter-related infection is one of the problems that have attracted widespread attention in the medical field in recent years. Scientific and standardized maintenance of central venous catheters is an important means to prevent various complications. Effective fixation and protection of the outer section of the catheter and the infusion connector is an important part of preventing related complications.

At present, the design of various central venous catheters and infusion connectors on the market cannot provide physical barrier protection devices. Daily nurses use adhesive tape products to fix the exposed catheters, and the extracorporeal catheters during the interval between infusion and maintenance (ranging from 1 day to 7 days) Infusion connectors and infusion connectors are directly exposed to the environment of the human body and body clothing, causing the catheters and connectors to be easily dirty, residual glue, hair adhesion, friction leading to loosening of tape curling, even damage to catheters and connectors, adhesive-related skin damage, etc., increasing infection risk, there are potential safety hazards. The existing infusion joint disinfection caps only have a short-term protection and disinfection effect on the infusion interface, but do not protect and fix the joint as a whole and the extracorporeal catheter.
