    摘要: A method for controlling a centrifuge blood component separation system for separating components of a blood product, the separation system comprising a centrifuge and a separation bag and at least one transfer bag. The method comprises selecting a nominal hematocrit value such that an actual hematocrit value is expected to be less than said nominal hematocrit; centrifuging a separation bag containing a volume of composite liquid so as to cause the sedimentation of at least a first component and a second component; transferring some of the first component to a first transfer bag; detecting time of passage of a red blood cell interface at a pre-selected location in the separation bag; and adjusting a predicted processing time based on the time of passage of the red blood cell interface.

    摘要: A centrifugal blood separation system comprising a rotor, a light source, an optical sensor, a control system, a separation vessel, and an optical cell on the separation vessel. The optical cell has a first extraction port extending radially outwardly into the optical cell, a red blood cell extraction port downstream from the first extraction port and extending into the optical cell beyond the first extraction port; and a dam between said first extraction port and said red blood cell extraction port, having an upper edge and a lower edge, wherein the first extraction port and the red cell extraction port are radially between the upper edge and the lower edge of the dam. Also, a first extraction port having a bore having a first diameter, a lumen having a second diameter smaller than the first diameter, and a frustro-conical passageway coupling the bore to the lumen.
