    摘要: A method and apparatus for collecting plasma reduced platelets potentially suspended in a synthetic solution from a donor. Whole blood is drawn from the donor and introduced into a separation chamber. Platelets are extracted from the separation chamber into a container, using, for example, surge (with anticoagulated plasma or a synthetic solution) or push methodologies. The remaining blood components in the separation chamber are returned back to the donor. The steps of drawing whole blood and introducing the whole blood into the separation chamber, extracting platelets from the separation chamber into the container, and returning the remaining components in the chamber back to the donor are repeated. The sequestered platelets in the container are reintroduced into the separation chamber, whereupon a plasma reduced platelet product is extracted.

    摘要: A method for washing platelets includes introducing anticoagulant into a platelet product container, drawing re-anticoagulated platelet product from the platelet product container, and introducing it into a centrifuge bowl. The centrifuge bowl separates the platelets from the supernatant in which they are suspended. The method then washes the platelets by introducing wash solution into the centrifuge bowl. As the wash solution is introduced into the bowl, it displaces the supernatant from the bowl and into a waste container. The method then introduces platelet additive solution into the centrifuge bowl, which displaces the wash solution from the centrifuge bowl and into the waste container and further wash the platelets. The method then repeatedly accelerates and decelerates the centrifuge bowl to resuspend the platelets in the platelet additive solution.

    摘要: A blood processing system for collecting and exchanging blood components includes a venous-access device for drawing whole blood from a subject and returning blood components to the subject. The system may also include three lines connecting the venous access device to a blood component separation device and an anticoagulant source. A blood draw line fluidly connects to the venous-access device to the blood component separation device. An anticoagulant line introduces anticoagulant into the drawn whole blood. A return line, fluidly connected to the venous-access device and the blood component separation device, and returns uncollected blood component to the subject. Each line may have a pump that controls flow through the line. The blood component separation device separates the drawn blood into a first blood component and a second blood component, and may be configured to send the first blood component to a first blood component bag.
