Abstract
A method and an apparatus for continuous processing of intra- or postoperative blood loss for autotransfusion are disclosed. 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.
