ABSTRACT:
A blood cell collection system having means for detecting when a cell separation chamber has filled with white blood cells, and flushing the cells out of the cell separation chamber into a collect bag. A red-green sensor senses the optical characteristics of fluid leaving the cell separation chamber. A baseline value is calculated. The device calculates a ratio of the intensities of red light and green light and a peak-to-peak ratio of intensities. If either ratio exceeds thresholds computed from the baseline, the device flushes the cells into the collect bag. A camera detects white cells passing into the cell separation chamber and the device calculates the number of cells being collected. If the calculated number of collected cells exceeds a certain limit, the cell separation chamber is flushed. If the device is unable to establish a baseline, the donation can proceed, relying solely on the calculated number of collected cells.
