PROBLEM TO BE SOLVED: To provide an organ preservation device for preserving an organ which is taken out from a living body, which can select an optimum preserving condition for the organ by analyzing the condition of the organ during preservation.SOLUTION: The organ preservation device includes: an organ preserving part (19) for preserving an organ (18) a preserving liquid perfusion part (20) for perfusing the organ (18) preserved in the organ preserving part with preserving liquid for preserving organs a temperature control part for controlling the temperature of the organ preserving part an introduction part (21) for introducing an active component agent into the preserving liquid circulating through the preserving liquid perfusion part (20) a function-evaluating part for evaluating functions of the organ by measuring the rate of flow of the preserving liquid perfusing the organ (18) and an adjusting part (33) for adjusting the temperature of the temperature control part, the type and the introduction amount of the active component agent introduced from the introduction part (21), and the rate of flow of the preserving liquid based on the data obtained by the function-evaluation.COPYRIGHT: (C)2013,JPO&INPIT
