Isolated organ perfusion, preservation and transfer system

Abstract

The invention provides an isolated organ perfusion, preservation and transfer system. The isolated organ perfusion, preservation and transfer system comprises a preservation box and a supporting device connected with the preservation box; a temperature control pool, a circulating pool arranged in the temperature control pool as well as circulating pipelines communicated with the top and the bottomof the circulating pool correspondingly are arranged in the preservation box; the circulating pipelines comprise a first pipeline and a second pipeline which are not communicated with each other; peristaltic pumps, pressure sensors, flow sensors, oxygenators and the like are arranged on the first pipeline and the second pipeline; the supporting device comprises a bottom plate and a foldable bracket arranged on the upper surface of the bottom plate; and one end, far away from the bottom plate, of the foldable bracket is connected with the preservation box. The isolated organ perfusion, preservation and transfer system has the advantages of portability, high airtightness, simplicity in connection, convenience in loading and disassembling and the like, and facilitates clinical application.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an isolated organ perfusion preservation transfer system. Background technique [0002] In recent years, with the continuous improvement of liver transplantation technology, the shortage of donor livers has become increasingly prominent, and the requirements for the preservation and transfer of donor livers have gradually increased. Therefore, how to expand the source of donor livers and ensure the quality of donor livers is a major challenge at present. . [0003] At present, the most commonly used method of liver donor preservation is static cold preservation, but it can only preserve liver tissue for a short period of time, and low temperature will aggravate ischemia-reperfusion injury, often leading to graft non-function and biliary complications. In order to make better use of marginal donor livers, better organ preservation techniques are urgently needed to reduce the damage...

Problems solved by technology

At present, mechanical perfusion systems are being studied at home and abroad, and there is no FDA-approved product on the market. However, the existing experimental systems are large in size, complicated to operate, not easy to carry, and expensive.
