摘要： Fluid separation chambers are provided for rotation about an axis in a fluid processing system. The fluid separation chamber may be provided with first and second stages, with the first and second stages being positioned at different axial locations. In another embodiment, at least one of the stages may be provided with a non-uniform outer diameter about the rotational axis, which may define a generally spiral-shaped profile or a different profile for fractionating a fluid or fluid component. One or more of the stages may also have a varying outer diameter along the axis. The profile of the chamber may be provided by the chamber itself (in the case of rigid chambers) or by an associated fixture or centrifuge apparatus (in the case of flexible chambers).

摘要： 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.

摘要： One embodiment relates to a pressure sensor apparatus, including a housing with a flexible member and an aperture configured to receive a fluid. The pressure sensor apparatus further includes a first member disposed on the flexible member, a second member removeably coupled to the first member configured to move in response to a pressure of the fluid and a sensor configured to detect the movement of the second member. The pressure sensor apparatus generates a pressure signal for the fluid based on the displacement of the second member.

摘要： Blood separation systems and methods are provided for controlling the interface between separated blood components. The system includes a centrifuge assembly having a light-transmissive portion, a light reflector, and a fluid processing region therebetween. An optical sensor system emits a scanning light beam along a path toward the light-transmissive portion, which transmits at least a portion of the scanning light beam to the fluid processing region and the light reflector. The light reflector reflects at least a portion of the scanning light beam toward the optical sensor system along a path substantially coaxial to the path of the scanning light beam from the optical sensor system toward the light-transmissive portion of the centrifuge assembly. The scanning light beam may be a white light beam or narrow spectrum beam. The reflected beam may be directed through the optical sensor system via optical fibers.

摘要： An optical monitoring system is provided for use with a blood processing system. The system includes a light source configured to illuminate a disposable flow circuit received in a centrifuge and a light detector configured to receive an image of the disposable flow circuit. A controller combines two or more of the images received by the light detector to generate a two-dimensional output. The output is used to control the separation of blood within the disposable flow circuit. The monitoring system may also be used to verify that the disposable flow circuit is suitable for use with the centrifuge or that the disposable flow circuit is properly aligned within the centrifuge. The monitoring system may be positioned outside of the centrifuge bucket which receives the centrifuge.
