ABSTRACT:
Closed filtering system for relatively fast and efficient removal of white blood cells from a red blood cell mixture. System comprises at least two blood bags in closed communication with each other via an intermediate filter assembly comprising a housing containing continuous filtering fiber. A preferred housing is tapered and the fiber preferably has a generally Y-shaped cross sectional area and it is adapted to permit substantial removal of white blood cells from a red blood cell mixture with minimal red blood cell hemolysis when the mixture is diluted with perservative solution and passed from one bag to the other at a relatively high flow rate. Filtration is completed within 24 hours, preferably within 6 hours, of whole blood donation.
