VORRICHTUNG UND VERFAHREN ZUM ENTFERNEN UNERWÜNSCHTER BESTANDTEILE AUS BLUTZELLEN

摘要

Apparatus and methods of collecting blood cells use a first container (16) to collect and separate blood. A filtration system (14) is provided that has a first, dual purpose, flow path (38) that is initially used to convey plasma and platelets from the first container (16) to a pair of transfer/storage containers (30,32). A second flow path (34) leads to a temporary transfer container (28) through a filtration device (36). The dual purpose fluid path (38) is next used to convey blood cells, now substantially freed of undesired matter by the filtration device, from the temporary storage container (28) to a satellite storage container (18) along a path that bypasses the first container (16), thereby avoiding contamination of the filtered blood cells by residual undesired matter in the first container (16).
