BLOOD BAG COMPRISING REMOVABLE HEAT TRANSFER MEMBER AND SYSTEM FOR PROVIDING WRIST-ACTION MOTION DURING FREEZING OR THAWING

摘要

One aspect of the present disclosure relates to a bag (10) for storing platelets or contaminated blood previously withdrawn from a subject. The bag comprises a flexible, closed container (12) and at least one removable heat transfer member (24). The container includes an inlet (14) adapted for fluid-tight connection to a tube member (16). A further aspect of the disclosure relates to a system for freezing or thawing platelets or contaminated blood, which comprises an agitator drive; a linkage arm operably connected to the agitator drive, the linkage arm configured to translate a rotary motion generated by the agitator drive to an angular reciprocation motion; a reciprocating arm operably connected to the linkage arm; and a container configured to hold the blood and being operably connected to a distal end of the reciprocating arm. Operation of the system provides a wrist-action motion to the container and thereby minimizes the amount of red blood cell (RBC) and platelet lysis caused by freezing or thawing.
