Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a fixing device for a puncture needle and a pipeline for hemodialysis. Background Art

[0002] Hemodialysis is an important means of treating diseases such as renal failure. It draws the patient's blood outside the body and uses a dialyzer composed of many hollow fibers to exchange substances with a dialysate containing electrolytes at concentrations close to that of the human body. This effectively removes metabolic waste from the patient's body, maintains electrolyte and acid-base balance, removes excess water, and ultimately returns the purified blood to the patient.

[0003] During hemodialysis, the puncture needle and tubing need to be fixed to the patient's body to prevent movement and falling off; however, the tip of the puncture needle is fixed with tape, and the end is connected to the dialysis tubing and clamped on the bed sheet with the end of the hemostat. Improper clamping of the hemostat can easily lead to poor blood flow in the tubing. In addition, when the patient moves, if the puncture needle is not firmly fixed with tape, the needle may easily fall off. Utility Model Content
