摘要

PROBLEM TO BE SOLVED: To provide a leukocyte remover for extracorporeal circulation, which is easy to manufacture and has both of a high leukocyte removing performance and a performance of treating a large amount of blood.;SOLUTION: In a container having the entrance and exit of blood, a filter layer comprising a prefilter layer composed of an aggregate removing filter material for removing aggregate contained in the blood and a main filter layer composed of a leukocyte removing filter material for removing leukocytes contained in the blood is housed. The aggregate removing filter material includes short fibers whose fineness is 0.7 dtex-4.0 dtex and fiber length is 1 mm-80 mm and a base fabric comprising long fibers whose fiber axis is oriented in a plane direction. The short fibers are entangled with the base fabric to attain total basis weight of 10 g/m²-80 g/m², and the layer of the short fibers forms a three-dimensional structure.;COPYRIGHT: (C)2011,JPO&INPIT
