<p>An artificial lung that is provided with a bundle of hollow fiber membranes (12) loaded in a gas exchange part (3) and a filter (15) loaded in a filter space (14) adjacent to the gas exchange part, wherein a blood channel (4) is formed in such a manner as to transversely pass through the hollow fiber membrane bundle and the filter. At the top end part of the blood channel, an exhaust port (16) for communicating the filter space with the external space is placed. The filter is formed of a sheet-type filtering material (17) having a plurality of parallel pleats (18) and the pleats are oriented in the vertical direction of the blood channel. The filter space is divided into a primary side space (14a) and a secondary side space (14b) by the sheet-type filtering material. The exhaust port is placed at the top end part of the blood channel and provided with exhaust passages (21a, 21b) by which exhausted gases discharged from the primary side and secondary side spaces are output in a state of being separated from each other.</p> |
