An Efficient Apparatus for Rapid Deoxygenation of Erythrocyte Concentrates for Alternative Banking Strategies

Figure 1

A schematization of the blood deoxygenation apparatus. Gas cylinders provide highest purity helium whose pressure is controlled through a manometer. Gas inlet is regulated in a closed system through a time valve which temporizes inlet and outlet towards a vacuum pump after 5 minutes of gas exchange within the plastic bag. Plastic bags are blocked almost horizontally as to favour gas exchange, through gentle agitation and temperature modulation. Sterility filters ensure the sterility of the whole system, either in the gas inlet or outlet tubing.
