Description

Technical Field

[0001] The utility model relates to the technical field of dialysis catheter fixing, in particular to a dialysis catheter fixing device. Background Art

[0002] Hemodialysis is also commonly known as artificial kidney or dialysis. It is a type of blood purification technology. It uses the principle of semipermeable membrane to remove harmful and redundant metabolic waste and excess electrolytes from the body through diffusion and convection, thereby purifying the blood and correcting the water electrolyte and acid-base balance. After the patient is removed from the hemodialysis machine, one end of the dialysis catheter is inserted into the superior vena cava of the body, and the other end is outside the body for connection to dialysis.

[0003] At present, dialysis catheters are usually wrapped and fixed with gauze. However, since part of the dialysis catheter is inside the body and the other part is outside the body, when the patient has too much clothing or people around the patient accidentally touch the patient, the probability of pulling the dialysis catheter is high, resulting in a greater risk of the catheter coming off. Based on this, the utility model proposes a dialysis catheter fixing device. Utility Model Content
