ABSTRACT:
Device for the separation of blood with a cannula with the aid of separation in a centrifuge with a blood pump in an inlet line and a collection storage bag, which can be emptied with the aid of a pressure device into a return line. The flow resistance R.sub.o of the return line is designed so that it has preferably about half of the flow resistance of the remainder of the return system. In a return/recirculation phase, the blood pump is operated at a predetermined recirculation flow rate F.sub.R, whereby a predetermined cannula infusion flow rate F.sub.N is established as a function thereof.
