PLASMA TREATMENT APPARATUS James H. De Vries Gaylord L. Berry ABSTRACT OF THE DISCLOSURE A plasmapheresis system in which whole blood is filtered through a microporous membrane to provide a plasma filtrate. The system includes a filter cell assembly having a membrane support member, a treatment membrane spaced from the membrane support member with a plasma treatment agent sandwiched between the treatment membrane and the membrane support member, and a micro- porous membrane spaced from the treatment membrane to form a plasma chamber between the treatment membrane and the microporous membrane. Whole blood is introduced to the side of the microporous membrane opposite to the plasma chamber, plasma is filtered through the microporous membrane to the plasma chamber and the plasma filtrate contacts the treatment membrane which operates to provide a mass transfer between the treatment agent and the plasma filtrate. The treated plasma is withdrawn from the plasma chamber, is mixed with the plasma-poor whole blood and is returned to the patient.
