Hollow fiber-type artificial lung.

摘要

An artificial lung (111) has an axially extending housing which accommodates a bundle of hollow fibers (116) retained within the housing (114) by a pair of walls (119, 120) provided at the ends of the housing. The housing has blood inlet (129) and outlet ports (132) defining a blood chamber (128) within the housing. Oxygen gas is passed through the hollow fibers (115) and blood is passed through the blood chamber so that a gas exchange may take place through the hollow fiber walls. The artificial lung is provided with a blood reservoir chamber (131) integral with the blood chamber, so that blood which has undergone a gas exchange inside the chamber may be stored within the reservoir (131).
