Problems solved by technology

[0003] At present, the consumable components used in liver perfusion are generally in an open environment, which cannot meet the requirements of aseptic operation during liver perfusion or continuous ice addition during liver cold perfusion. Moreover, the existing liver storage container package uses the liver Flat lying, unable to keep the liver in a living environment close to that of the human body during the perfusion process

Abstract

The invention discloses a liver perfusion consumable assembly. A sealed bionic storage device is arranged in a box body of the liver perfusion consumable assembly, so that the liver perfusion consumable assembly can meet the sterility requirement in the liver perfusion process; the bionic storage device is provided with an ice adding chamber, so that ice can be continuously added by the liver perfusion consumable assembly in the liver perfusion process; and besides, a liver suspending component is arranged in a storage chamber of the bionic storage device, so that a physiological environment for livers in the liver perfusion process is relatively close to that in a living human body.

Description

technical field [0001] The invention relates to the technical field of liver transplantation, in particular to a liver perfusion consumable assembly. Background technique [0002] Liver transplantation is the only effective treatment for end-stage liver disease of all causes. However, due to organ shortages, transplant waiting lists and pre-transplant mortality continue to be high. Although the number of donors has increased recently, livers suitable for transplantation The number is still limited by cold preservation and ischemia-reperfusion injury, etc. Therefore, perfusion is often used to solve the above problems, among which: perfusion (Machine perfusion, MP) is a new type of organ preservation and transport. Connect your own blood vessels to the organ perfusion system, and the system will continue to perfuse the isolated organs with perfusate during the organ preservation and transport stages, and at the same time supply the isolated organs with oxygen and nutrients. ...
