GAS PLASMA TREATED POROUS MEDIUM AND METHOD OF SEPARATION USING SAME

摘要

A leukocyte depletion filter assembly and a method for removing leukocytes and other deleterious matter from a biological fluid, the filter assembly comprising a housing (10) having an inlet (11), an outlet (12), a vent (30) and a liquid flow path between the inlet (11) and the outlet (12); and a degassing element (50) communicating with the vent (30) for removing gas from the fluid; and a porous medium (36) positioned in the housing (10) across the fluid flow path, the surface of the porous medium (36) having been modified by exposure to a gas plasma stream.
