In a process and assembly to extract a specific blood component from a patient, the process operates under continual laminar flow. Blood is taken from the patient using a first tube and surrendered to a centrifuge in which the components are separated. Simultaneously, blood is returned to the patient at the same rate at that which is removed. The centrifuge separation is determined by a geometrical factor, by the centrifuge speed of rotation, and the position of the incoming blood tube to the centrifuge. The separation of blood components is characterized by a separation optimization coefficient which is between 140 and 190 pref. 176. During separation of thrombocytes, the blood flow rate is between 30 and 100 ml/min and the separation coefficient is between 600 and 700, pref. approx. 649. |
