Abstract: Blood processing systems and methods employ two sensors (334, 336), one (334) to detect a condition of plasma exiting a separation device (18) and another sensor (336) to detect a condition of a cellular component exiting the separation device (18). The first sensor (334) detects, e.g., contamination of the plasma due to the presence of unwanted cellular components. The second sensor (336) detects, e.g., dilution of the cellular component due to presence of plasma. Blood processing parameters are carried out based, at least in part, by conditions detected by one or both of the sensors (334, 336).

Abstract: A blood separation system (10) is described. The system comprises a device (14, 18) which, in use, operates to separate whole blood into red blood cells and plasma, a whole blood inlet line (290) for conveying a flow of whole blood into the device, a plasma collection line (292) for conveying a flow of plasma from the device, and a red blood cell collection line (294) for conveying a flow of red blood cells from the device. A first sensing assembly (334) including a first sensor in the plasma collection line is provided which in use operates to detect a characteristic of plasma in the flow of plasma and to generate a first output. A second sensing assembly (336) including a second sensor in the red blood cell collection line is provided which in use operates to detect a characteristic of red blood cells in the flow of red blood cells and to generate a second output. A controller (16) operates to control flows in the plasma collection line and the red blood cell collection line based upon the first and second outputs.

Abstract: Systems and methods separate pump the blood cells through an in-line leukofilter to a blood cell storage container. The leukofilter has a filtration medium enclosed within a flexile housing. The systems and methods can employ a fixture to restrain expansion of the flexible filter housing during operation of the pump.

Abstract: A blood separation chamber (18) is provided for rotation about an axis. In one implementation, the blood separation chamber (18) comprises a base (388) that includes formed walls that define a hub (120). A separation channel (126) extends about the hub (120). Flow passages (142, 144, 146) extend between the hub (120) and the separation channel (126). The hub (120) enables attachment of external tubing to convey blood to and from the separation channel (126) through the hub (120). In another implementation, the chamber (18) includes an interior channel, which includes a recess (386) that extends outside the bounds of the walls establishing separation zone. The recessed interior channel (386) permits the yields of individual blood components separated in the chamber to be maximized without cross-contamination or contamination by other components present in the chamber (18).

Abstract: Blood processing systems and methods (10) convey blood cells from a blood ce ll source into a blood component collection flow channel that includes a blood cell storage container and an in-line filter to remove leukocytes from blood cells before entering the blood cell storage container. The systems and methods also convey additive solution from an additive solution source into the blood component collection flow channel. The systems and methods alterna te the conveyance of blood cells through the filter with the conveyance of additive solution through the filter.
