Abstract
A method and device for thawing pouches of frozen transfusion material including a membrane which provides a barrier within an interior of the device with the membrane receiving the pouches of frozen material therewithin. The interior of the device includes a sump having thawing fluid stored therein and maintained at a constant target temperature which is to be achieved by the frozen transfusion material to be thawed. The pouch of material to be thawed, after placement within the membrane, is exposed (through the membrane) to hydrostatic forces associated with the fluid in the sump collapsing the membrane on the pouch while pulsating jets impinge indirectly upon the pouch through the membrane. In this way, as the contents within the pouch thaw, circulation of the fluid within the pouch occurs for more rapid realization of the target temperature for the fluid within the pouch.
