Description

A long-term indwelling catheter fixing bandage for hemodialysis patients

technical field

The utility model relates to a long-term indwelling catheter fixing bandage for hemodialysis patients, which belongs to the technical field of hemodialysis-related medical devices.

Background technique

Hemodialysis is one of the renal replacement treatments for patients with acute and chronic renal failure. It drains blood from the body to the outside of the body, and passes through a dialyzer composed of countless hollow fibers. ) inside and outside the hollow fibers, through the principles of dispersion, ultrafiltration, adsorption and convection for material exchange, remove metabolic waste in the body, maintain electrolyte and acid-base balance; at the same time remove excess water in the body, and convert the purified blood The whole process of reinfusion is called hemodialysis;

At present, patients who need regular hemodialysis all year round usually have vascular access established in their bodies.
