Abstract:
1. A method for separating a volume of whole blood into at least a plasma component and a red blood cell component comprising: loading a disposable set comprising a separation bag and at least a wash solution bag onto the rotor of a centrifuge; centrifuging the separation bag containing a volume of whole blood so as to separate therein at least a first component comprising plasma and a second component comprising red blood cells and an intermediate component comprising platelets and mononuclear cells; transferring, on the rotor, the first component into a plasma component bag connected to the separation bag, during centrifugation of the separation bag; transferring, on the rotor, the intermediate component into an intermediate component bag connected to the separation bag during centrifugation of the separation bag; transferring by centrifugation, on the rotor, into the separation bag a volume of wash solution from the wash solution bag on the rotor during centrifugation of the separation bag; mixing the volume of wash solution with the second component; centrifuging the separation bag so as to separate therein a washed red blood cell component and a supernatant component comprising used wash solution; and transferring, on the rotor, the supernatant component into a waste bag connected to the separation bag, during centrifugation of the separation bag.
