[0002] Hemodialysis is one of the renal replacement therapies for patients with acute and chronic renal failure. It drains blood from the body to the outside of the body and passes it through a dialyzer composed of countless hollow fibers. The blood and an electrolyte solution containing electrolytes at concentrations similar to those in the body exchange substances inside and outside the hollow fibers through the principles of diffusion, ultrafiltration, adsorption and convection, thereby removing metabolic waste from the body, maintaining electrolyte and acid-base balance, and removing excess water from the body. The entire process of returning the purified blood is called hemodialysis.

[0003] However, in reality, nursing hemostasis often uses a pressing hemostasis method to stop bleeding, that is, the tourniquet is limited to the bleeding area and the bleeding is stopped by manual pressing.
