Single needle continuous hemapheresis apparatus and methods

摘要

The apparatus provides a continuous flow of whole blood to a separator (20) while there is alternate drawing of whole blood from a donor and reinfusion of blood constituents to the donor. To this end, whole blood is fed from the donor to a reservoir (16) while whole blood is simultaneously fed to the separator (20), without passing through the reservoir. During reinfusion of blood constituents from the separator (20) to the donor, whole blood is fed from the reservoir (16) to the separator (20).
