Abstract

Disclosed is an ischaemia-free organ perfusion device and perfusion method. The perfusion device perfuses an isolated organ at normal temperature during whole transplantation, and comprises a first container, a second container, a first flow path, a second flow path, a third flow path and a fourth flow path. The perfusion device and the perfusion method are capable of maintaining the blood flow of the isolated organ during whole transplantation without interruption by machine perfusion, recovering the blood of the organ, effectively avoiding the interruption of blood supply for the organ during the whole transplantation, and improving the prognosis of organ transplantation.
