Abstract
The use of membranes in blood processing range from the use of large-pore structures for filtration of blood for the removal of large particles (>20 microm transfusion filters) to membranes for the dialysis of blood for the removal of low molecular weight solutes in the treatment of renal failure. Within the past 20 years, membranes have been applied in the separation of plasma from whole blood. Compared to centrifugal plasma separation membrane, plasma separation is preferred when used with online plasma fractionation since the plasma is free of cells. In addition, membranes have also been applied in the online treatment of plasma for the selective removal of macromolecules in selected disease states obviating the need for plasma replacement products. The membranes used for plasma separation and fractionation may be distinguished from conventional dialysis membranes and high-flux membranes used in hemofiltration by their very high or select passage of plasma proteins. Membrane techniques are simple and safe to apply and can be competitive to other plasma separation and treatment technologies.
