Abstract: A portable, lightweight, storage pack for blood bags which maintains lower temperatures within the blood bags during transport and transfusions. The storage pack has an outer shell with insulated panels and flexible hinges that cover an internal chamber. The storage pack is refrigerated and a blood bag is inserted into the shell through openings. Flexible straps maintain the blood bag in the chilled storage pack during transport and transfusions. These flexible straps permit access to the blood bag access ports to allow transfusions without removing the bag from the chilled shell. A hanging strap on the top of the outer shell hangs the storage pack and the contained blood bag in a vertical position during transfusions.
