Claim 10:
11. 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 and includes an annular shell aperture near the second end;
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, and through the annular shell aperture to an exterior of the cylindrical shell near the second end, 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 such that heat exchanger fluid flows from the heat exchanger fluid inlet through an inlet chamber to the entirety of the heat exchanger hollow fibers near the second end, and to a post chamber in fluid communication with the entirety of the heat exchanger hollow fibers near the first end; and
a fluid flow distributor in fluid communication with the post chamber, wherein the fluid flow distributor defines a plurality of radially distributed fluid distributing apertures equally spaced around a circumference of the fluid flow distributor.
