Description

technical field

[0001] The present invention relates to a compound artificial liver support system, more specifically, relates to a system that can replace the liver function of patients with acute liver failure (acute liver failure, ALF) in a long period of time, and support patients with severe liver failure Waiting for liver transplantation, or allowing patients with liver failure to gradually restore their own liver tissue and its regeneration and compensation functions, thereby improving the survival rate and survival time of ALF patients with a compound artificial liver support system. In addition, the present invention also relates to the use method of the above-mentioned composite artificial liver support system, which can greatly improve the therapeutic effect of the above-mentioned system. Background technique

[0002] Acute liver failure is a common critical disease with a mortality rate as high as 70-90%. For this disease, the current treatment methods generally...
