Abstract

The invention provides a portable liver normal-temperature storage device. The device comprises a water-bath case which is used for accommodating a liver and is arranged in a tank body, wherein a filter connected with the liver by virtue of a return pipe, an oxygenation device, a controller and a storage battery which is used for supplying power to the controller are respectively arranged in the tank body; one input end of the oxygenation device is connected with the output end of the filter by virtue of a peristaltic pump and a honeycomb duct, the other input end of the oxygenation device is connected with an oxygen cylinder by virtue of an oxygen pipe, and the output of the oxygenation device is connected with the liver by virtue of an inflow pipe and the flow electric control valve which is arranged on the inflow pipe; the inflow pipe between the output end of the oxygenation device and the input end of the electric controlled valve is connected with a drug propeller by virtue of a pipeline connector and a drug conduit which is connected with the pipe connector; a bile container connected with the liver is arranged in the water-bath tank; the controller which is respectively connected with the peristaltic pump, the flow electric controlled valve and a heat device in the water-bath case and the storage battery are arranged in the tank body. The portable liver normal-temperature storage device is simple in structure and convenient to operate, and can be used for storing an in-vitro liver for a long time, even repairing the liver.

Description

technical field [0001] The invention relates to a device for preserving liver at normal temperature. In particular, it relates to a portable liver preservation device at normal temperature. Background technique [0002] Since Professor Thomas Starzl successfully completed the first clinical liver transplantation in 1963, liver transplantation technology has developed rapidly and has become the main method for the treatment of end-stage liver diseases. At present, the shortage of liver donors in the world is becoming more and more serious, and this problem is particularly prominent in my country. About 1.5 million patients in China need organ transplants every year, but only about 10,000 organ transplants are performed every year, and a large number of patients die due to the shortage of donor organs. With the continuous improvement of the level of social civilization in our country, the number of donor organs from death row prisoners has dropped sharply, and donation after ...
