Technical Field

[0001] The utility model relates to the technical field of hemodialysis catheter fixing, in particular to a hemodialysis catheter fixing and protecting structure. Background Art

[0002] Hemodialysis (HD) is a method of treating renal failure. It uses a special machine to draw blood from outside the body, clean and filter it through a filter, and then return the cleaned blood to the patient. The role of hemodialysis is to replace the function of the kidneys, remove metabolic products and excess fluid from the blood, and maintain the body's electrolyte and acid-base balance.

[0003] In the prior art, the hemodialysis catheter is a pipe that connects the patient's blood to the hemodialysis machine. In order to ensure that the catheter remains stable and safe during the hemodialysis process and reduce the risk of infection and other complications, the catheter needs to be fixed to the patient. The existing fixing method is generally to fix it with a fixing belt or transparent tape. After long-term use, the puncture site of the catheter and the patient's body will become loose, increasing the risk of the catheter shifting or falling off. Utility Model Content
