Abstract
A device that can be used to store blood product and/or cellular culture that may or may not be under pressure. The device includes a chamber that can be hermetically sealed and a flexible secondary bag which can be placed in the chamber. The chamber is designed to receive at least one secondary bag that contains a conventional storage bag containing blood product and/or cellular culture. The storage conditions are created in the chamber and may or may not include 1) creating a pressure higher than atmospheric pressure, 2) creating a refrigerated temperature, and/or 3) providing agitation to the secondary bag. The secondary bag is filled with a gas system that is used to facilitate in the storage of the blood product and/or cellular culture. The secondary bag can be made of a material and/or include a coating or film that is impermeable to the gas system and to the gas inside the chamber. The higher-than-atmospheric pressure inside the chamber can be created by pumping an inexpensive gas, for example, air, into the chamber. The gas used to pressurize the chamber can be different from the gas system in the secondary bag.
