Patent ID: 8091618

Claim:
An exchange apparatus comprising: a perfluorinated thermoplastic housing; cords of two or more non-porous perfluorinated thermoplastic hollow tubes, said cords having a shape set by thermal annealing, the non-porous perfluorinated hollow tubes in said cords having a first end portion and a second end portion and hollows passing therebetween; the first end portions of said non-porous perfluorinated thermoplastic hollow tubes being fusion bonded at least at a periphery of said non-porous perfluorinated thermoplastic hollow tubes through a perfluorinated thermoplastic resin to form a first unified terminal end block in which the end portions of said non-porous perfluorinated thermoplastic hollow tubes are fluid tightly bonded together in a fused fashion with the perfluorinated thermoplastic resin; said second end portions of said non-porous perfluorinated thermoplastic hollow tubes being fusion bonded at least at a periphery of said non-porous perfluorinated thermoplastic hollow tubes through a perfluorinated thermoplastic resin to form a second unified terminal end block in which the end portions of said non-porous perfluorinated thermoplastic hollow tubes are fluid tightly bonded together in a fused fashion with the perfluorinated thermoplastic resin; said first unified terminal end block and said second unified terminal end block having through hole communication with the hollows of the unbonded portions of said non-porous perfluorinated thermoplastic hollow tubes; said first unified terminal end block having a first fluid inlet connection to supply a first fluid to said non-porous perfluorinated thermoplastic hollow tubes and said second unified terminal end block having a first fluid outlet connection to remove said first fluid from said non-porous perfluorinated thermoplastic hollow tubes; said perfluorinated thermoplastic housing fusion bonded with said perfluorinated thermoplastic resin to form a single entity of fusion bonded perfluorinated thermoplastic materials; said perfluorinated thermoplastic housing having a first housing port wherein a second fluid enters the exchange apparatus and a second housing port wherein said second fluid exits the housing.
