Claims
- 1. A blood processing system comprising
a blood processing set including
a donor flow channel to convey blood from a donor, a blood processing flow channel including a blood separation chamber to centrifugally separate blood cells from donor whole blood, and a blood component collection flow channel including a blood cell storage container and an in-line filter to remove leukocytes from the blood cells before entering the blood cell storage container, the inline filter including a filter medium and a flexible housing enclosing the filter medium, a blood processing device including
a pump station adapted to be placed into communication with the donor flow channel, the blood processing flow channel, and the blood component collection flow channel, a centrifuge station adapted to support the blood separation chamber and to rotate the blood separation chamber, and a controller to operate the pump station in multiple modes, including a processing mode, during which the pump station is operated to convey whole blood in the donor flow channel into the blood processing flow channel for separation of the blood cells in the blood separation chamber, and a collection mode, during which the pump station is operated to convey at least some of the blood cells in the blood processing flow channel into the blood component collection flow channel for on-line removal of leukocytes and collection in the blood cell storage container, a fixture to restrain expansion of the filter housing during operation of the pump station in the collection mode, the fixture including a bracket to enable releasably attachment of the fixture to the blood processing device.
- 2. A system according to claim 1wherein the controller includes a function to derive a value reflecting volume of blood cells present in the blood cell storage container after passage through the filter as a percentage of volume of blood cells conveyed to the filter.
- 3. A system according to claim 1wherein the pump station includes a fluid pressure actuated pump and an actuator to apply fluid pressure to the pump.
- 4. A system according to claim 1wherein the blood processing device is mounted in a case sized to enable hand transport, and wherein the case includes a receptacle mating with the bracket to hold the fixture.
- 5. A system according to claim 1wherein the blood processing device includes a base and a lid hinged to the base, and wherein the case includes a holder mating with the bracket to hold the fixture.
- 6. A system according to claim 1wherein the blood processing device includes a base and a lid hinged to the base, and wherein the lid includes a receptacle mating with the bracket to store the fixture.
- 7. A system according to claim 1wherein the blood cells comprise red blood cells.
