Abstract:
1. 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 extending coaxially within the housing and having a core interior in fluid communication with the blood inlet, the heat exchanger core including an outer surface and at least one pair of elongate core apertures formed within the outer surface, the pair of elongate core apertures configured to permit blood to pass from the core interior; 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 plurality of elongate core apertures may flow radially outward across the heat exchanger hollow fibers; a cylindrical shell extending coaxially about the heat exchanger core, the cylindrical shell including a shell aperture configured to permit blood to pass to an exterior of the cylindrical shell, the shell aperture comprising a circumferentially disposed aperture disposed near an end of the cylindrical shell longitudinally opposite that of the blood inlet, such that blood entering the cylindrical shell must move with a longitudinal flow component before passing through the aperture; 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 shell aperture may flow across the gas exchanger hollow fibers in a longitudinal direction and towards the blood outlet.
