Abstract
An exchanger includes an outer casing having an inlet port and an outlet-port for a first fluid, and an inlet port and an outlet port for a second fluid, and a bundle of hollow fibers located within the outer casing and being in flow communication with the inlet and outlet port for the second fluid. A central core is located in the outer casing and the bundle of fibers is arranged around the central core. The central core includes an inlet manifold connected to the first fluid inlet port, and an outlet manifold connected to the first fluid outlet port.
Claims20
An exchanger, comprising:
- an outer casing having an inlet port and an outlet port for a first fluid, and an inlet port and an outlet port for a second fluid;
- a bundle of hollow fibers located within the outer casing, and being in flow communication with the inlet and outlet port for the second fluid;
- and
- a central core located in the outer casing and around which the bundle of fibers is arranged, the central core including an inlet manifold connected to the first fluid inlet port, and an outlet manifold connected to the first fluid outlet port.
A blood oxygenator, comprising:
- an outer casing having an inlet port and an outlet port for blood, and an inlet port and an outlet port for oxygen;
- a bundle of hollow fibers located within the outer casing, and being in flow communication with the oxygen inlet and outlet ports;
- and
- a central core located in the outer casing and around which the bundle of fibers is arranged, the central core including an inlet manifold connected to the blood inlet port, and an outlet manifold old connected to the blood outlet port.
An exchanger, comprising:
- an outer casing having an inlet port and an outlet port for a first fluid, and an inlet port and an outlet port for a second fluid;
- a bundle of hollow fibers located within the outer casing, and being in flow communication with the inlet and outlet port for the second fluid;
- and
- a central core having a substantially elongated tubular shape of predetermined length located in the outer casing and around which the bundle of fibers is arranged;
- an inlet manifold recessed in and extending along substantially the entire length of the central core, the inlet manifold being connected to the first fluid inlet port;
- and
- an outlet manifold recessed in and extending along substantially the entire length of the central core, the outlet manifold being connected to the first fluid outlet port.
