Patent ID: 11517855

Abstract:
The present disclosure relates to an artificial, extracorporeal system for supporting the function of the liver of a patient suffering from liver failure, which is characterized in that it comprises a first high-flux or high cut-off hollow fiber membrane dialyzer which is perfused on the lumen side with the patient's blood and wherein a buffered aqueous solution comprising human serum albumin is passed in a continuous flow through the filtrate space of said first dialyzer, a second hollow fiber membrane dialyzer which removes water-soluble substances from the dialysate of said first dialyzer, and a third, integrated hollow fiber membrane dialyzer which is perfused with the retentate of second hemodialyzer and which allows the passage of certain amounts of albumin over the membrane wall into the filtrate space which is populated with adsorbent material. The system can be used for the treatment of acute liver failure and acute-on-chronic liver failure.
