An intervivos blood processing system for centrifugally separating red blood cell and platelet components from whole blood includes a separation chamber for separating red blood cell and white blood cell components, and a collection chamber for collecting platelet components. Each chamber is formed with closely-spaced sidewalls defining respective generally flat interior chambers therebetween and is mounted on a rotatably driven carriage substantially tilted from a parallel arrangement with respect to the carriage axis of rotation at a slight angle whereby the red blood cell component is caused to collect in shoulder regions of the separation chamber and the platelet component is caused to collect on the sidewalls of the collection chamber. The processing chambers are preferably each formed from sheets of flexible hemo-compatible plastic sealed about their periphery to define the chambers therebetween, and are received on the carriage between removable carrier plates having recesses which define the shape of the chambers under fluid pressure. |
