Compared with the prior art, when the plasma thawing apparatus 10 provided by the utility model thaws the plasma bag 20, the isolation module 13 seals the plasma bag 20 in vacuum, on one hand, the plasma bag 20 and the heat-conducting medium 113 are completely isolated, the potential pollution risk is reduced, the requirement on cleanness of the heat-conducting medium is reduced, and the cost is reduced; on the other hand, the vacuum sealing enables the silica gel bag 1314 and the outer surface of the plasma bag 20 to be attached without a gap, thereby eliminating the adverse factors that air is not beneficial to heat conduction, increasing the heat conduction area, improving the heat conduction efficiency of the isolation module 13 and the plasma bag, and being uniformly heated in the constant temperature environment provided by the temperature control module 11.
