An artificial lung (11, 111, 250) has an axially extending housing which accommodates a bundle of hollow fibers (17, 116, 146) retained within the housing (15, 114, 251) by a pair of walls (18, 19, 119, 120, 256, 257) provided at the ends of the housing. The housing has blood inlet (27, 129, 263) and outlet ports (28, 132, 268) defining a blood chamber (26, 128, 262) within the housing. Oxygen gas is passed through the hollow fibers (16, 115, 254) 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, 158) integral with the blood chamber and capable of being communicated with the blood chamber, so that blood which has undergone a gas exchange inside the chamber may be stored within the reservoir. A heat exchanger (269, 298) is disposed at a point preceding, following or intermediate the blood chamber and blood reservoir chamber, which construct a blood circuit. |
