Abstract
A method and an apparatus for continuous processing of intra- or postoperative blood loss for autotransfusion. According to the present invention, certain cells of the cell suspension to be processed, mainly the red blood cells, are concentrated by centrifuging in a separation unit and removed from the separation unit without being rinsed or washed in the separation unit. The concentrated cell fraction is diluted with a physiological solution, preferably a Ringer's solution, after being removed from the separation unit.
