<p>Method of separating blood, in particular for recovering thrombocytes and/or leucocytes, the whole blood coming from the donor being separated in a separation means of a centrifuge into an erythrocyte fraction, cell-poor plasma, a thrombocyte fraction and/or possibly a leucocyte fraction, the separated fractions of the blood being discharged via a flexible tubing system of discharge lines out of the separation chambers of the centrifuge and constantly predetermined amounts of separated cell-poor plasma returned to the whole blood to be separated or to the already separated erythrocytes in the separation chamber, and a separation apparatus for carrying out the method comprising a separator having one or more separating chambers connected together and a flexible tubing system which includes a supply line (1, 2) for the supply of the whole blood to be separated to the separator and discharge lines each for the separate discharge of the erythrocyte fraction (10), the cell-poor plasma (3, 5), the thrombocyte fraction (11) and/or possibly leucocyte fractions and a branch line (7) disposed on the output side from the separator in the discharge line (3) for cell-poor plasma for returning cell-poor plasma, the supply and discharge lines and the branch lines (7) of the flexible tubing system being equipped with pumps, and the branch line (7) disposed on the output side of the separator is led off between the separator and the pump (6) and the pump (8, P) diposed in the branch line (7) delivers a predetermined plasma amount.</p> |
