Hollow fiber-type artificial lung.

摘要

An artificial lung (250) has an axially extending housing which accomodates a bundle of hollow fibers (146) retained within the housing (251) by a pair of walls (256, 257) provided at the ends of the housing. The housing has blood inlet (263) and outlet ports (268) defining a blood chamber (262) within the housing. Oxygen gas is passed through the hollow fibres (254) and blood is passed through the blood chamber so that the gas exchange take place through the hollow fiber walls. A heat exchanger (269) is disosed at a point preceding, following or intermediate the blood chamber and blood reservior chamber, which constract a blood circuit.
