Description

technical field

[0001] The invention belongs to the technical field of biomedicine, and relates to a medical device, a core device for the treatment of a biological or hybrid biological artificial liver-a artificial liver filling stent perfusion bioreactor. Background technique

[0002] The bioartificial liver uses part or all of the bioactive cells of the liver cells to enter the bioreactor, and the blood or some components flow through the reactor. During this process, the bioactive cells absorb the toxic substances in the blood, Transformation and detoxification, on the other hand, synthesize a variety of biologically active substances and release them into the blood to achieve the purpose of removing toxic components in the blood. The bioreactor is the core device of the biological and hybrid artificial liver support system. It is the place where exogenous liver cells and the patient's blood or plasma exchange substances. As a reactor, it generally meets the following ba...
