Background technique

Hemodialysis is one of the renal replacement treatments for patients with acute and chronic renal failure. It drains the blood from the body to the outside of the body and flows through a dialyzer composed of countless hollow fibers. The blood is mixed with an electrolyte solution containing a similar concentration to the body (dialysis). Liquid) inside and outside each hollow fiber, exchanges substances through diffusion and convection, removes metabolic waste in the body, maintains electrolyte and acid-base balance; at the same time, removes excess water in the body and reinfuses the purified blood. It's called hemodialysis.

During hemodialysis, due to the long time, the patient usually lies on a bed. Hemodialysis can easily cause the human body to fall into a state of confusion. The human body will move its arms unconsciously, causing the puncture needle to shake along the blood vessels of the human body, resulting in puncture of the blood vessel or Risk of needle detachment;
