Abstract:
1. A gravity driven device for filtering a donor's blood comprising: a) a filter arrangement for the separation of blood into plasma and cellular components, comprising: b) a collection container for receiving the donor's blood upstream of said inlet line of said housing wherein said donor blood collection container has a vertical lower edge that is positioned with a preset vertical spacing above an upper edge of the filter arrangement; c) a feed line for fluid communication between said donor blood collection container and said filter arrangement; d) a collection container for receiving cellular components of the donor's blood downstream from said outlet area of the filter system such that a vertical upper edge of said cellular components collection container is disposed approximately at the vertical level of the lower edge of the filter arrangement; e) a collection container for receiving blood plasma downstream from said outlet chamber of the filter arrangement wherein said blood plasma collection container has an upper edge that is disposed at a vertical level lower than the lower edge of the filter arrangement wherein a set of connections between said filter arrangement, said collection containers via said inlet line, said outlet line to said inlet chamber, and said outlet line for said outlet chamber are germ tight, but can be broken via any known means without admitting air or causing interfering effects; f) a connector element in fluid communication with said donor blood collection container wherein said connector element is coupled to the donor to draw blood from the dohor into said donor blood connection container; g) a leukocyte depletion filter coupled to said feed line between said blood donor collection container and the filter arrangement; and h) a venting, connecting said outlet line to said feed line, upstream of said leukocyte depletion if filter.
