[0002] Kidney disease is a common and frequently occurring disease. If it worsens, it can develop into uremia, which seriously endangers people's health. Chronic kidney disease has become another important disease that threatens human health after cardiovascular and cerebrovascular diseases, tumors, and diabetes, and has become a global public health issue. Dialysis is a separation and purification technology that separates small molecules from biological macromolecules based on the principle that small molecules diffuse into water or buffer through a semipermeable membrane. Dialysis therapy is a treatment method that allows components in body fluids to be excreted from the body through a semipermeable membrane. Hemodialysis, also known as artificial kidney or dialysis in popular terms, is a type of blood purification technology. It uses the principle of a semipermeable membrane to diffuse and remove various harmful and excess metabolic wastes and excess electrolytes in the fluid out of the body, thereby purifying the blood and correcting the water electrolyte and acid-base balance.
