ABSTRACT:
A continuous blood centrifugation cell includes a bell shaped outer container rotatable about a central axis, a coaxial inner volume displacement body which has a central longitudinal passage, and a circularly shaped partition which has a central aperture and which is coaxially enclosed between the body and the bottom of the container. A stationary housing is connected to and encloses the upper end of the container and has a coaxial inner conduit, a coaxial intermediate conduit, and a coaxial outer conduit. The housing has a stationary passage near the upper end of the container and is in communication with the lower end of the outer conduit for the removal of the lighter fraction blood components from the container. The intermediate conduit extends downwardly into the central passage of the body and has the lower end thereof closely spaced from the partition for the inlet of blood into the container. The inner conduit extends downwardly through the central passage of the body and through the central aperture of the partition with the lower end thereof closely spaced from the bottom of the container for the removal of the red blood corpuscles from the container. The cell also includes a sealing gasket within the aperture to seal the space between the inner conduit and the aperture to facilitate the removal of the red blood corpuscles through the inner conduit, during centrifugation.
