PROBLEM TO BE SOLVED: To stabilize a blood stream, to perform whole blood perfusion, to raise fixing density and purification efficiency of an adsorption radical to have a level being the same as that of a system using porous beads, and to provide a surface structure suitable for the adhesion of a functional group onto the surface of the membrane at a low cost in a power saving process. SOLUTION: A plasma separation membrane for hemocatharsis includes a hollow fiber membrane supporting not less than one kind of acid functional groups chosen from a carboxyl group and a sulfonic group, where water permeability is≥7,500ml/hr×kPa×m<SP>2</SP>and an albumin permeability is≥10%, and supporting not less than one kind of basic functional groups chosen from primary, secondary, tertiary, and quaternary amine and imine. The maximum hole diameter on the inner surface of the plasma separation membrane for hemocatharsis is≤2 microns. COPYRIGHT: (C)2005,JPO&NCIPI
