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 through a dialyzer composed of countless hollow fibers. Blood and electrolyte solutions containing similar concentrations to the body are carried out inside and outside the hollow fibers through the principles of diffusion, ultrafiltration, adsorption and convection. The entire process of material exchange, removal of metabolic waste from the body, maintenance of electrolyte and acid-base balance, removal of excess water from the body, and return of purified blood is called hemodialysis.

The patient's dialysis time lasts for more than 4 hours. During the dialysis process, patients may easily lose needles and puncture blood vessels while sleeping, sitting up, and involuntarily moving. The commonly used site for hemodialysis is generally the arteriovenous fistula of the upper limb. Simply put, the arteriovenous fistula is to anastomose the arterial end and the venous end of the blood vessels of the upper limb to arterialize the veins and increase the venous blood flow (250ml/min ), in order to achieve sufficient blood flow during hemodialysis, so as to perform continuous hemodialysis and achieve the purpose of treatment.

During the dialysis process, medical staff usually use functional medical tape to fix the dialysis catheter on the patient's limbs or treatment sheets.
