Abstract

A continuous flow centrifuge bowl includes a rotatable outer body, and a top and bottom core that are rotatable with the outer body. The bottom core has a wall extending proximally from a bottom wall. The proximally extending wall is radially outward from at least a portion of the top core and, together with the top core, defines a primary separation region in which initial separation of the whole blood occurs. The bowl may also have a secondary separation region located between the top core and the outer body, and a rotary seal that couples an inlet port and two outlet ports to the outer body. The inlet port may be connected to an inlet tube that extends distally into a whole blood introduction region. Additionally, one of the outlet ports may be connected to an extraction tube that extends into a region below the bottom core.
