Development of Liver Normothermic Machine Perfusion Repair and Assessment System / 中国医疗器械杂志

ABSTRACT

This paper introduced a liver normothermic machine perfusion repair and assessment system. This system consists of a liver normothermic machine perfusion device, a fluorescence imaging system and a tissue oxygen detector. The normothermic machine perfusion device can continuously perfuse the donor liver and monitor and control the perfusion parameters in real time. The fluorescence imaging system can detect the indocyanine green metabolized by the liver to evaluate the microcirculation and the metabolism function of hepatocytes. The tissue oxygen detector can monitor the change of oxygen partial pressure of liver tissue in real time to evaluate the state of cell oxygen consumption.
