초록 ▼

A hollow fiber blood oxygenator is provided having a plurality of enclosed, coaxial heat exchanger coils, having a common header to insure uniform temperature in the coils. An enclosed fiber bundle is concentrically positioned inside the heat exchanger coils to define a flow path around the coils and through the fiber bundle. The heat exchanger coils and the outside of the fiber bundle are tapered to provide a close fit. Gas manifolds direct gas flow to and from the hollow fibers.

대표청구항 ▼

A hollow fiber oxygenator comprising an enclosed fiber bundle unit comprising: a bundle of hollow fibers open at the ends thereof for ducting gas therethrough, said bundle exterior being tapered at a predetermined angle; a casing around said fiber bundle, said casing being tapered at approximately said predetermined angle, said bundle and said casing being dimensioned and positioned such that said bundle has been axially inserted into the casing sufficiently far to create an interference fit between the exterior of the bundle and the interior of the casing, which results in readily compressing said bundle; and means defining a fluid inlet and means defining a fluid outlet in said casing for ducting fluid through spaces between said hollow fibers; a heat exchanger unit comprising; a plurality of tubular, coaxial coils stacked along a common axis defining an inner cavity tapered approximately at said predetermined angle and corresponding in size to the exterior of said casing, said bundle unit being concentrically positioned with said cavity creating a tight fit between said casing and said coils, said bundle unit cooperating with said heat exchanger unit to define a fluid flow path around said coils; means defining a fluid inlet and means defining a fluid outlet for ducting fluid through said coils; cap means cooperating with said heat exchanger unit to define gas passages which provide gas to the interior of said hollow fibers and remove gas from said hollow fibers; means communicating with said fluid outlet in said casing communicating fluid away from said oxygenator; said casing fluid inlet being near the top of the bundle unit and said casing fluid outlet being near the bottom of said bundle unit and opening to a center core in the bundle unit; and further comprising: an internally located tue communicating fluid from adjacent the bottom of said fiber bundle center core to means defining a port on the top of said oxygenator to allow sampling of fluid which has passed through said fiber bundle.
