ABSTRACT:
A process and apparatus are provided for continuously separating blood into plasma and cellular component fractions and returning the latter to the subject in admixture with a makeup fluid. The separation is effected by continuously ultrafiltering the subject's blood at specified shear stresses and pressures employing a membrane ultrafilter, preferably having a pore size of 0.45 microns, and a disclosed flow system.
