PROBLEM TO BE SOLVED: To provide an artificial lung system, even in a case of being used for a long time, capable of suppressing a decrease in gas exchange efficiency, while suppressing an increase in a device cost and power consumption.SOLUTION: An artificial lung system 1A includes: an extracorporeal circulation path 90 in which blood is circulated a blood feed pump that pneumatically feeds blood a blood feed pump drive part 41 that drives the blood feed pump 40 and an artificial lung 10 for exchanging gases in blood. The artificial lung 10 includes a gas exchange part including a hollow fiber membrane, where oxygen and carbon dioxide flow inside thereof and blood flows outside thereof. The artificial lung 10 further includes a gas inflow part 25 at one end side of the hollow fiber membrane and a gas outflow part 26 at the other end side thereof. In the artificial lung system 1A, the gas outflow part 26 is configured to be heated by a high-temperature air that is heated by heat generated by the blood feed pump drive part 41.COPYRIGHT: (C)2015,JPO&INPIT【課題】装置コストの増大や電力消費量の増加を抑制しつつ、長時間使用した場合にもガス交換効率の低下が抑制できる人工肺システムを提供する。【解決手段】人工肺システム1Aは、血液が循環する体外循環経路90と、血液を圧送する送血ポンプ40と、送血ポンプ40を駆動する送血ポンプ駆動部41と、血液のガス交換を行なう人工肺10とを備える。人工肺10は、酸素および二酸化炭素がその内部を通流しかつ血液がその外部を通流する中空糸膜が配置されたガス交換部を含む。人工肺10の中空糸膜の一端側にはガス流入部25が設けられ、他端側にはガス流出部26が設けられる。人工肺システム1Aにあっては、ガス流出部26が、送血ポンプ駆動部41にて生じる熱によって加温された高温の空気によって加熱可能となるように構成される。【選択図】図1
