technical field

The utility model relates to the technical field of hemodialysis equipment, in particular to a safety fixing device for indwelling dialysis catheters in internal jugular veins.

Background technique

In clinical practice, hemodialysis catheters are mainly used to create short-term venous access for hemodialysis, blood collection, manometry and fluid infusion. The working principle of the hemodialysis catheter is that after the tube is inserted into the central venous system, it is connected to the hemodialysis catheter line and the dialysis machine. The blood containing metabolic wastes from the dialysis patient is inhaled from the arterial end of the catheter, and passes through the circulation pipeline and the dialysis machine. Physical mechanisms such as convection and adsorption remove excess water and toxins from the body, adjust the patient's electrolyte and acid-base balance, and the purified blood is pumped back into the central vein of the human body at the venous end of the catheter.

The dialysis catheter is composed of a needle-punched tube body and two extension tubes, one of which is used to input blood, and the other is used to lead out blood. At present, the fourth-level fixation of the dialysis catheter in the hospital is fixed with adhesive tape. If the patient sweats or the skin is wet, the adhesive tape will loosen. To a certain extent, the risk of management affects the comfort of patients' activities.
