Background

Hemodialysis is one of the kidney replacement treatment modes of patients with acute and chronic renal failure. The principle of hemodialysis is that solutes move from a high concentration solution to a low concentration direction through a semipermeable membrane. Hemodialysis involves the movement of solutes and the movement of water, i.e., the exchange of substances between blood and dialysate in a dialyzer (artificial kidney) by means of semipermeable membrane contact and concentration gradients, causing metabolic wastes and excess electrolytes in the blood to move towards the dialysate, and calcium ions, bases, etc. in the dialysate to move towards the blood.

In the process of blood transfusion, the temperature of the transfused blood is close to the temperature of a human body, otherwise, the bearing capacity and the activity of the heart of a patient are reduced, and life danger is brought to the patient.
