WIPO Patent Application WO/2021/010319
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a blood processing filter excellent in white blood cell removal rate and filtration time (filtration speed). The problem can be solved by the following blood processing filter. A blood processing filter that includes a container having an inlet part and an outlet part for blood, and a filter medium positioned between the inlet part and the outlet part in the container. The filter medium includes a filter layer. The filter layer includes a non-woven fabric. Fibers of the non-woven fabric have an orientation degree X in an X-axis planar direction of the filter layer and an orientation degree Y in a Y-axis planar direction orthogonal to the X-axis planar direction, the maximum value of the ratio of the orientation degree X to the orientation degree Y (orientation degree X/orientation degree Y) being 1.2 or more.
