Abstract
Methods are provided for identifying a disposable flow circuit in a blood processing system. At least a portion of the disposable flow circuit is positioned within a centrifuge that is rotatable about a rotational axis and has a high-G outer wall with a window facing radially away from the rotational axis. The disposable flow circuit is monitored through the window to detect the presence of an expected identification feature and/or an expected alignment feature. If the expected feature is detected, a blood separation procedure is initiated, with the procedure including monitoring the disposable flow circuit through the window to detect characteristics of a fluid within the disposable flow circuit. If the expected feature is not detected, an alarm condition is generated and initiation of the blood separation procedure is prevented.
