ABSTRACT:
A reliable flow rate plasmapheresis system includes a rotating enhanced vortex type of membrane filter coupled to receive a flow of anticoagulated whole blood and separate concentrate and filtrate in responses thereto. An anticoagulant pump is coupled to mix controlled amounts of anticoagulant with the input blood flow. Degradation of plasma flow rate during multiple extraction-reinfusion cycles is inhibited by selecting the starging anticoagulant pH value and controlling the anticoagulant flow rate relative to the whole blood to establish a final whole blood/plasma pH value in the range of 6.8 to 7.2, with an anticoagulant to blood ratio in the range of 1:6 to 1:25.
