Claim 0:
1. A blood processing apparatus comprising:
a housing having a first end and a second end;
a blood inlet at the first end;
a heat exchanger fluid inlet and a heat exchanger fluid outlet at the second end;
a heat exchanger core situated in the housing;
a cylindrical shell extending coaxially about the heat exchanger core;
a blood flow distributor in fluid communication with the blood inlet near the first end and configured to direct blood from the blood inlet at the first end through the blood flow distributor to a heat exchanger chamber, the blood flow distributor defining a plurality of radially distributed blood distributing apertures spaced around a circumference of the blood flow distributor;
a plurality of heat exchanger hollow fibers disposed in the heat exchanger chamber, the heat exchanger hollow fibers configured to direct heat exchanger fluid from the heat exchanger fluid inlet at the second end through the heat exchanger hollow fibers to a fluid flow distributor near the first end, wherein the fluid flow distributor defines a plurality of radially distributed fluid distributing apertures equally spaced around a circumference of the fluid flow distributor; and
a central chamber disposed in the heat exchanger core and in fluid communication with the plurality of fluid distributing apertures in the fluid flow distributor, the central chamber configured to direct heat exchanger fluid from the plurality of fluid distributing apertures in the fluid flow distributor near the first end through the central chamber to the heat exchanger fluid outlet at the second end.
