ABSTRACT:
A blood inlet manifold is provided for connection to a first end of a blood heat exchanger including a plurality of hollow conduits arranged in a bundle. A plurality of first ends of the conduits terminate adjacent the first end of the blood heat exchanger and a plurality of second ends of the conduits terminate adjacent a second end of the blood heat exchanger. The blood inlet manifold includes a blood inlet nozzle having an upstream segment and a downstream segment. The upstream segment is connectable to a tube for conveying blood. The blood inlet manifold further includes a generally conical wall member connected to the downstream segment of the blood inlet nozzle and connectable to the first end of the blood heat exchanger. The connection of the blood inlet manifold to the blood heat exchanger defines a chamber between the conical wall member and the first set of ends of the conduits. An interior of the downstream segment of the blood inlet nozzle opens into this chamber.
