Abstract
A method and an apparatus for the automatic control of a blood centrifuge, including a controller that processes four input values and two output parameters. The four input values include the hematocrit value of the input blood, the volume of the red cells present in the centrifuge, the filling level of the centrifuge, and, selectively, the hematocrit value for collected blood at the end of the filling step and the time required for the filling step. The two output parameters include the flow rate of the blood into the centrifuge and either the time required for the filling step (when the hematocrit value is provided as input) or the predicted hematocrit value (when the time for the filling step is provided as input).
