Abstract
An improved centrifuge bowl and related system is disclosed which is particularly apt for enhanced autologous blood salvage applications. The centrifuge bowl assembly includes a rotatable outer bowl, an internal spacer interconnected therewithin, and a stator assembly for introducing/removing fluid during rotation of the outer bowl and internal spacer. The outer bowl and internal spacer are configured to define a lateral passageway at the bottom of the assembly which terminates in an upward-facing port for fluid passage therethrough into an annular, cylindrical collection region. The annular port may be defined by a peripheral fin on the spacer and may be of a width that is less than the width of the cylindrical, annular collection region, wherein separated blood components (e.g. red blood cells) will accumulate across the width of the port during blood fill/wash cycles. As a result, enhanced washing is realized while maintaining throughput rates.
