Abstract:
1. A monitoring system for a centrifuge blood processing system for separating fluid components and having a separation chamber rotating about a central rotation axis, comprising: a first light source in optical communication with said centrifuge blood processing system for providing an incident light beam for illuminating an observation region including at least part of said separation chamber, thereby generating light transmitted, scattered or both from said observation region; a light collection element in optical communication with said centrifuge blood processing system for collecting at least a portion of said light transmitted, scattered or both from said observation region; a programmable controller for providing an operational procedure for said monitoring system; and an independent dedicated control circuit in electrical communication with said programmable controller and electrically coupled to said first light source, said control circuit comprising means for receiving command parameters from said programmable controller and means for energizing said first light source at a first selected rotation and de-energizing said first light source after a selected duration.
