ABSTRACT:
A method of storing blood is disclosed in which a plastic blood collection bag is further supplied with silicone rubber into which pure Ca(OH).sub.2 has been compounded. The method is an efficient way to prolong the useful life of blood, especially the erythrocytes, since their viability can be enhanced by removal of CO.sub.2 from the blood. Such removal can be a method of maintaining an adequate pH balance in the complex blood system which appears to be essential to maintaining the blood in storage for prolonged periods of time.
