ABSTRACT:
An intervivos blood processor includes a processing chamber wherein whole blood is separated into its red blood cell, white blood cell and plasma components in the presence of a centrifugal force field. The white blood cell component is removed from the chamber by means of a tubing segment having a free floating end within the chamber and a density corresponding to the density of the white blood cell component. Since the free end of the tubing assumes the same position in the chamber as the white blood cell component the tubing collects only this component notwithstanding variations in the flow rate of the blood through the chamber and the centifugal force field applied to the chamber.
