Apparatus and method for the reduction of the leukocytes content of blood and blood components.

摘要

A high efficiency leucocyte-depletion filter for use with packed red cell concentrate derived from freshly drawn blood comprises a fibrous filter medium with a pore size of from 0.5 to less than 4 mu m and a CWST of from 55 to 80. The filter is preferably used in conjunction with a gel prefilter and, optionally, a microaggregate filter so as to minimize clogging. In a preferred embodiment, the voids volume is 60% to 85%.
