Portable organ donation donor mechanical perfusion system

Abstract

The invention discloses a portable organ donation donor mechanical perfusion system. The portable organ donation donor mechanical perfusion system comprises a blood circulation oxygenation closure device and a control device electrically connected with the blood circulation oxygenation closure device; the blood circulation oxygenation closure device comprises an oxygenator, a centrifugal pump, a blood exchanger, an arterial cannula, and a venous cannula; the blood exchanger is internally provided with a piston capable of moving vertically, the upper part of the piston is a first storage end for storing donor blood, the lower part of the piston is a second storage end for storing perfusion liquid, a blood input end and the output end of the centrifugal pump are communicated with the first storage end through a first three-way valve, and the blood input end and the output end of the centrifugal pump are communicated with the second storage end through a second three-way valve, so that low-temperature perfusion can be completed without cannulation in the abdominal aorta after laparotomy. Moreover, since a balloon is arranged at the tip end of the arterial cannula, only the balloon isneeded to be inflated or injected with water when only an abdominal organ is perfused, and convenience is realized.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a portable mechanical perfusion system for organ donation. Background technique [0002] Organ transplantation is the only treatment option for patients with end-stage organ diseases, but the shortage of donor organs seriously restricts organ transplantation treatment. As the country promotes and further deepens the reform in the field of organ transplantation, organ donation from deceased citizens has become the main source of donor organs in my country way. [0003] Organ donations from deceased citizens in our country can be divided into three categories, namely, brain death (DBD), cardiac death (DCD) and brain-death double death (DBCD) organ donations, among which DCD and DBCD donors will inevitably experience hypotension before obtaining organs , shock, cardiac arrest, etc. caused by warm ischemic injury, which has a serious impact on organ quality, and ultimately en...

AI Technical Summary

Problems solved by technology

[0004] Donor organ harvesting under the support of ECMO has the following disadvantages: (1) the perfusion blood is distributed throughout the body, and the perfusion cannot only target the abdominal organs; (2) the normal temperature blood cannot be converted into a low-temperature organ preservation solution in a timely manner during the perfusion process; (3) perfusion The process cannot quickly reduce the temperature of the donated organ as needed; (4) ECMO equipment is complex, bulky, and inconvenient to carry
