One aspect of the present disclosure relates to a bag (10) for storing blood previously withdrawn from a subject. The bag comprises a flexible, closed container (12) and at least one removable heat transfer member (24) adhered to an outer surface portion (26) of the container. The container can include an inlet (14) adapted for fluid-tight connection to a tube member (16) through which blood can flow. A further aspect of the disclosure relates to a system for freezing or thawing 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) hemolysis caused by freezing or thawing.Un aspect de la présente invention concerne une poche pour stocker du sang prélevé au préalable sur un sujet. La poche peut comprendre un contenant fermé, souple, et au moins un élément de transfert de chaleur amovible, collé à une partie de surface extérieure du contenant. Le contenant peut comprendre une entrée en son sein, qui fait partie du contenant. Lentrée peut être conçue pour établir un raccordement étanche aux fluides avec un élément de tube à travers lequel le sang est amené à sécouler.
