Abstract:
A blood separation system comprisinga driven element including a separation zone to receive whole blood,a drive element coupled to the driven element to cause separation of whole blood in the separation zone into plasma and concentrated red blood cells,an inlet pump element coupled to the driven element to convey into the separation zone whole blood from a blood donor selected from a population of blood donors, the whole blood of the selected blood donor having a known beginning hematocrit value that varies within the population of blood donors according to morphology of the selected blood donor, andcontrol means including an input for receiving the known beginning hematocrit value of the selected blood donor, the control means being operative for commanding the inlet pump element and the drive element as a function of the known beginning hematocrit value to obtain concentrated red blood cells having an end hematocrit value that remains substantially constant for the population of blood donors despite variances in the known beginning hematocrit value according to morphology of the selected blood donor.
