Abstract

The invention relates to a, especially a perfusion preservation device for liver. The perfusion preservation device for liver includes a water-bath case perfused with a preserving liquid. The device is characterized in that the inside of the water-bath case is provided with a bile duct perfusion tube connected to a bile duct, a hepatic artery perfusion tube in connection with a hepatic artery and a portal vein perfusion tube connected to a portal vein. The ends of the bile duct perfusion tube, the hepatic artery perfusion tube and the portal vein perfusion tube are all connected to a liquid storage pot through a pipeline. And the other end of the liquid storage pot is in connection with a pressure adjustable hydraulic pump that is connected to the water-bath case by a pipeline directly. Earmarked for liver perfusion preservation, the device of the invention is characterized by simple structure, convenient use, long storage and the like.

Description

technical field [0001] The invention relates to a liver perfusion preservation device, in particular to a liver perfusion preservation device. Background technique [0002] As we all know, according to the report of the World Health Organization, there are currently about 350 million people in the world who are carriers of hepatitis B virus, about 45 million people die of liver cirrhosis every year, and 60 million people die of primary liver cancer. my country is the country with the most serious hepatitis B infection in the world, and about 140 million people are carriers of hepatitis B virus, accounting for one-third of the world. Among them, 30 million are chronic hepatitis, liver cirrhosis, and primary liver cancer, and as many as 300,000 people die of chronic liver disease every year. Zhejiang Province has always been a major province of liver disease, with an average of one in 10 people infected with hepatitis B virus. The prevailing wine culture and overloaded work,...
