Patent ID: 8394049

Claim:
A blood processing apparatus comprising: a housing having a blood inlet and a blood outlet, the blood inlet extending into an interior of the housing; a heat exchanger core arranged coaxially within the housing, the heat exchanger core including an outer surface configured to impart a radial blood flow component and a core aperture in fluid communication with the blood inlet and configured to permit blood to pass from the blood inlet to an exterior of the heat exchanger core; heat exchanger hollow fibers disposed about the heat exchanger core such that a heat exchanger fluid may flow through the heat exchanger hollow fibers and blood passing from the core aperture may flow across the heat exchanger hollow fibers; a cylindrical shell extending coaxially about the heat exchanger core, the cylindrical shell including a surface and one or more shell apertures extending through the surface, all of the one or more shell apertures disposed near an end of the cylindrical shell opposite to an end near which the core aperture is located, the surface configured such that blood flowing through the cylindrical shell is forced to flow from the core aperture to one or more of the shell apertures, the one or more shell apertures configured to permit blood to pass to an exterior of the cylindrical shell; and gas exchanger hollow fibers disposed about the cylindrical shell such that gases may flow through the gas exchange hollow fibers and blood passing from the one or more shell apertures may flow across the gas exchanger hollow fibers.
