Centrifugal displacer pump

摘要: Apparatus is disclosed for centrifugally separating blood into one or more components, such as a plasma-rich component, and plasma-poor component. This apparatus employs centrifuge intended to be used immediately adjacent donor. A flexible displacement container having displacer fluid operated diaphragm positioned within processing chamber of the rotor. The comprises pair contoured support shoes which structurally supports container. Separated first component expressed from by movement collected in receiver rotor spins. reservoir mounted closer axis rotation than communication therewith. centrifugal force created spinning creates pressure differential between sufficient pump said pouch, thus moving expressing components bag.
