ABSTRACT:
Collection systems and methods use a separation chamber that receives blood or a suspension containing red blood cells and performs a separation process including separation of red blood cells from the blood or suspension. The separation chamber contains, during the separation process, a red blood cell volume. An outlet line is coupled to the separation chamber to remove red blood cells from the chamber device, at least in part, while the separation process occurs. A collection container is coupled to the outlet line to receive a volume of red blood cells removed from the separation chamber. A controller includes a processing function that, during the separation process, includes comparing the volume of red blood cells received by the collection container to a selected targeted red blood cell collection volume to derive a difference. The controller includes another processing function that includes purging substantially all the red blood cell volume occupying the separation chamber into the collection container when the red blood cell volume occupying the separation chamber approximates the difference.
