Claims
- 1. An exchanger, comprising:
- an outer casing having a tubular outer wall;
- an angled flange connected to and extending from the outer casing, the flange having a generally L-shaped cross-section and including a wall extending substantially parallel to the outer wall of the casing and being circumferentially spaced therefrom, the flange wall having a distal end;
- at least one cap located on an end of the outer casing, the cap having a wall extending substantially parallel to the outer wall of the casing and being circumferentially spaced therefrom;
- a central core;
- a bundle of hollow fibers arranged around the central core and positioned directly between the outer wall the central core;
- a circumferential groove located in an edge of the cap wall for receiving the distal end of the flange wall.
- 2. The exchanger of claim 1 further including resin disposed in the groove.
- 3. The exchanger of claim 1 wherein the cap engages both the distal end of the flange wall and the central core.
- 4. The exchanges of claim 3 wherein the cap engages the central core in a press-fitting relationship.
- 5. The exchanger of claim 1 wherein the central core includes a blood inlet port, a blood inlet manifold connected to the blood inlet port, a blood outlet port, and a blood outlet manifold connected to the blood outlet port.
- 6. The exchanger of claim 1 wherein a circumferential angled flange is disposed on opposite ends of the outer wall and a cap is located on each of said opposite ends.
- 7. The exchanger of claim 1 wherein said at least one cap includes two caps, each cap being located on an opposite end of the tubular outer wall.
- 8. An exchanger having one of a plurality of capacities, comprising:
- an outer casing having a tubular outer wall with an outer casing diameter, the outer casing diameter being different for each of the plurality of capacities and having an angled circumferential flange extending therefrom by a radial length, the radial length being different for each of the plurality of capacities;
- a bundle of fibers located within the outer casing;
- a central core having a central core diameter less than the outer casing diameter located in the outer casing and around which the bundle of fibers is arranged, a thickness of the bundle of fibers; and
- a cap having a cap diameter located on an end of the outer casing, the cap having a wall extending substantially parallel to the outer wall of the casing and being spaced radially therefrom; wherein
- the outer casing diameter and the radial length cooperate to cause the wall of the cap to engage the angled flange; and wherein each of the plurality of capacities of the exchanger is defined by the difference between the outer casing diameter and the central core diameter.
- 9. An apparatus as claimed in claim 8, wherein the wall of the cap includes a circumferential groove that receives a portion of the angled flange.
- 10. An apparatus as claimed in claim 9, wherein resin is disposed in the groove.
- 11. An apparatus as claimed in claim 8, wherein the central core includes a blood inlet port, a blood inlet manifold connected to the blood inlet port, a blood outlet port, and a blood outlet manifold connected to the blood outlet port.
- 12. An apparatus as claimed in claim 8, further including a heat exchanger integrally connected thereto and having an outlet port which is flow connected to an interior portion of the outer casing.
