Abstract
A multiple blood bag system comprising a donor bag for receiving blood from a donor, and one or more transfer bags, communicating by flexible tubing with the donor bag, for receiving a blood component from the donor bag. In accordance with this invention, the various bags may be made of differing materials to provide differing characteristics to the bags as desired. For example, the transfer bag or bags may be made of a translucent, flexible, sterilizable material which is free of blood extractable ester-type plasticizers, and may have a relatively high carbon dioxide diffusion capacity. The donor bag may be made of a translucent, flexible, sterilizable material which contains preferably at least five percent by weight of a specified ester plasticizer, sufficient to cause a substantial reduction in plasma hemoglobin produced by blood stored under normal conditions for 21 days in the donor bag, when compared with blood in a corresponding, plasticizer-free donor bag stored under equivalent conditions.
