초록 ▼

The fluid processing apparatus of the present invention comprises a housing having a first fluid inlet and a first fluid outlet; a fluid processing tubular means received in the housing; partitions securing the opposed ends of the fluid processing tubular means to the housing in a fluid tight seal to partition the housing interior into a first fluid chamber in fluid communication with the first fluid inlet and the first fluid outlet and a second fluid chamber defined in the fluid processing tubular means; a second fluid inlet and a second fluid outlet in fluid communication with the second fluid chamber; and projections formed on an inner surface of one end portion of the housing so as to project toward the nearer end opening of the housing, said partition of the one end portion side of said housing being secured to the one end portion of the housing so that the projections are positioned within the partition. Therefore, if a large annular portion where the fluid processing tubular means is not present is formed in the end portion of the housing, because the projections are positioned in the annular portion of the partition, shrinkage of the potting composition forming the partition is suppressed and any separation between the partition and the inner surface of the housing due to the shrinkage of the potting composition is prevented. Further, it is also prevented to form a weak bond portion between the partition and the inner surface of the housing.

An artificial lung equipped with a heat exchanger comprising: a heat exchanger comprising: a heat exchange housing having: an internal wall; a heat-exchange fluid inlet; a heat-exchange fluid outlet; a first end portion; and a second end portion; heat-exchange tubular means positioned in said heat exchange housing; first and second partitions formed of a potting composition for respectively securing a first and a second end portion of said heat-exchange tubular means to said heat exchange housing in a fluid tight seal to partition an interior portion of said heat exchange housing into a heat-exchange fluid chamber in fluid communication with said heat-exchange fluid inlet and said heat-exchange fluid outlet, said heat exchange fluid chamber being defined by an outside surface of said heat exchange tubular means, said internal wall of said heat exchange housing and an internal surface of each of said first and second partitions, said internal surfaces of said partitions facing an interior of said heat exchange fluid chamber, and a blood chamber being defined by an internal surface of said heat-exchange tubular means; a blood inlet and a blood outlet in fluid communication with said blood chamber; a plurality of spaced apart projections formed on an inner surface of said first end portion of said heat exchange housing so as to project in a direction toward an end of said first end portion of said heat exchange housing and away from said second end portion of said heat exchange housing; said first end portion of said heat exchange housing being positioned relative to said first partition so that an entirety of each of said plurality of spaced apart projections formed on said inner surface of said first end portion of said heat exchange housing are embedded in an annular area within said first partition such that a plurality of projection-free areas are formed between adjacent projections where said plurality of projections are not present, said projection-free areas enabling said potting composition to flow therethrough when said first partition is being formed from said potting composition; and an artificial lung comprising: an artificial lung housing having a gas inlet and a gas outlet; a bundle of gas-exchange hollow fibers positioned in said artificial lung housing; partitions for respectively securing a first and a second end portion of said bundle of gas-exchange hollow fibers to said artificial lung housing in a fluid tight seal, to partition an interior of said artificial lung housing into a gas chamber in fluid communication with said gas inlet and said gas outlet, and a blood chamber defined in said gas-exchange hollow fibers; and a blood inlet portion and a blood outlet portion in fluid communication with said blood chamber; said first partition of said heat exchanger formed in said first end portion of said heat exchange housing facing and being connected to a given one of said partitions of said artificial lung.
