Hemodialysis (HD) is one of the kidney replacement treatment modes of patients with acute and chronic renal failure, and is a process of automatically draining the body to the outside, exchanging blood with electrolyte solution containing similar body concentration through dispersion, ultrafiltration, adsorption, convection and the like by a dialysis machine, removing metabolic waste in the body, maintaining the balance of electrolyte and acid-base, simultaneously removing excessive water in the body, and returning the purified blood.
Often, a patient with renal failure requires long-term, timed hemodialysis to maintain normal life expectancy before renal function is restored, and this hemodialysis must be performed in a medical facility under the supervision of a medical care provider (so-called "central dialysis"). However, dialysis in medical institutions, especially in general hospitals, is often at risk of accidental infection, such as cross-infection with infectious diseases like hepatitis b, hepatitis c, aids, syphilis, tuberculosis, etc., due to the complexity of the personnel and the weak resistance of the patients themselves. Furthermore, during the period of serious infectious diseases, such as new coronavirus epidemic, the patient is difficult to go to the hospital for dialysis on time and may even be life-threatening.
There is a continuing desire for a way in which patients can perform Home Hemodialysis, i.e., Home Hemodialysis (Home hemodynamics), without requiring the patient to go to a hospital for dialysis, but rather to perform Home Hemodialysis.
