Abstract

The invention relates to a portable liver extracorporal charging preservation apparatus for liver transplantation comprising a constant temperature water bath tank for liver storage, an oxygenator, a hepatic artery charging circulation loop and a portal vein charging circulation loop, and an intelligent control device for controlling bath tank temperature and flow capacity of charging circulation loop. The liver dual perfusion model created by the invention can carry out oxygen cycle charging to the exsomatized liver at normothermia.

Description

technical field [0001] The invention relates to an extracorporeal liver preservation device for liver transplantation, in particular, it is a portable liver extracorporeal perfusion preservation device. Background technique [0002] A number of medical studies have shown that the only effective way to treat acute liver failure and advanced liver disease is liver transplantation, and its survival rate can be increased by 55% to 75% compared with traditional medical treatment. However, human livers are rare and generally need to be obtained from a long distance, which brings great difficulties to clinical application. How to keep the isolated liver alive during the period from harvesting to clinical application has become a current research topic. In the prior art, there are many methods for liver preservation, but recent research results show that the extracorporeal perfusion method has a better preservation effect, and the isolated liver can survive for 2 to 3 days. If a p...
