POLMONE ARTIFICIALE DEL TIPO A FIBRE CAVE,CON INCORPORATO SCAMBIATORE DI CALORE

摘要

A hollow fiber-type artificial lung having an enclosed heat exchanger comprises a first housing and a second housing connected together coaxially. A gas exchange chamber is defined in the first housing by a pair of spaced walls and a bundle of hollow fibers designed for gas exchange arranged in the first housing and between the pair of walls. The hollow fiber bundle is preferably constricted at the central portion to increase the packing ratio of the hollow fibers. The second housing is connected to the first housing by way of a blood chamber and has a pair of spaced apart walls, and multiple tubes which extend lengthwise between the pair of walls to effect heat exchange between a circulating heat exchange medium and the blood flowing through the multiple tubes.
