  • Process for treating and/or removal of substances from liquid, especially whole blood
    Patent number: 4361484
    Abstract: A process for the treating of and/or removal of substances from a liquid, especially whole blood, via a semipermeable microporous membrane (13, 14, 15) through adsorption and/or biological reaction by means of a biologically active material. Said whole blood is exposed to pressure variations at the membrane surface in a way such that a penetrating fraction of said whole blood is flowing in an alternating flow path through the membrane walls for contacting said biologically active material.Said biologically active material is asymmetrically immobilized in and on the surface of the side of said membrane that faces away from said whole blood. Alternatively, said biologically active material may be bound to an unsoluble matrix behind said membrane.Said membrane is for example provided within a casing (7, 8, 9) comprising inlet (10) and outlet (11) for said whole blood.
