Abstract
An aseptically pure dispensing anticoagulant device adapted to be connected to a blood collection set and which may be aseptically treated by ethylene oxide or other high diffusivity sterilant without deleterious effects upon the anticoagulant. Various embodiments are shown; in one, a collapsible pouch is provided which includes a barrier against diffusion of water vapor and ethylene oxide. In another embodiment, a rigid anticoagulant container is employed which necessitates a secondary volume of air in a surrounding pouch to provide air to displace liquid in the rigid container as it passes into the set.
