Abstract

A continuous method for production of a porous hollow fibre membrane having regioselective affinity for compounds in blood or other biologically active fluids to be removed during purification of blood or said fluids is disclosed, as well as a porous hollow fibre membrane produced by said method, an adsorption device containing such a porous hollow fibre membrane, and use of such a porous hollow fibre membrane.
