Abstract

The embodiment of this application discloses a biological artificial liver purification circulation unit and artificial liver support system. Biological conversion and synthesis function, give full play to the purification advantages of various means. The bioartificial liver purification circulation unit provided in the embodiment of the present application includes a plasma storage bag, a pipeline warmer, a plasma circulation pump, a high-flux filter, a neutral resin adsorber, Dissolved oxygen-pH monitors and bioreactors.

Description

technical field [0001] The invention relates to a medical device, in particular to a bioartificial liver purification circulation unit and an artificial liver support system. Background technique [0002] The blood purification technology for artificial liver replacement therapy is developing rapidly. At present, the domestic treatment is dominated by component plasma exchange, while the research hotspot abroad is the albumin dialysis adsorption system. The representative method is the molecular adsorption recirculation system (MARS). The basic principle of this type of method is to use albumin solution as the dialysate in the protein dialysis cycle, so that the protein-bound toxins and other types of toxin molecules in the patient's blood are transferred to the albumin solution through the MARS dialysis membrane, so that the blood can be obtained. Purification. At the same time, the protein solution purification and regeneration cycle purifies the polluted albumin solution ...
