HM78-6 APPARATUS FOR SEPARATING BLOOD DEB:BJF INTO COMPONENTS THEREOF 1/19/79 ABSTRACT OF THE DISCLOSURE Apparatus is disclosed for centrifugally separat- ing blood into a first blood component, such as a plasma- rich component, and a second blood component, such as a plasma-poor component. This apparatus employs a self- balancing centrifuge intended to be used immediately adjacent to a blood donor. The blood pathway is completely disposable and includes a phlebotomy needle and blood compatible tubing connecting the phlebotomy needle to a flexible blood process- ing bag designed to be supported within a contoured processing chamber in the centrifuge rotor so that second blood component travels along a short internal bag dimension to achieve sepa- ration. A displacement chamber having a fluid operated dia- phram is also positioned within blood processing chamber of the centrifuge rotor. Separated first blood component can be expressed from the flexible blood bag by movement of the diaphram and collected in a receiver container as the centri- fuge rotor spins. The centrifuge rotor can then be stopped to allow return of second blood component to the donor.
