PROBLEM TO BE SOLVED: To prevent nitrogen dioxide from being generated, i.e., prevent oxygen and nitrogen monoxide from being mixed by forming an oxygen adding region and a nitrogen monoxide adding region in a chamber, and providing a gas inlet and a gas outlet for respective regions. SOLUTION: In this artificial lung device, for a chamber 5, an oxygen-adding region 3 having a built-in hollow yarn bundle 61 as an oxygen-adding means, and a nitrogen monoxide-adding region 4 having a built-in hollow yarn bundle 62 as a nitrogen monoxide-adding means are formed. Then, in respective regions 3 and 4, gas current inlets 31 and 41, and gas current outlets 32 and 42 are provided respectively. Then, the end surfaces of both end sections of the hollow yarns, which are fixed by a fixing member 7, are opened, and oxygen is made to flow in from the gas current inlet 31, and nitrogen monoxide is made to flow in from the gas current inlet 41. The oxygen and the nitrogen monoxide which have flowed into the chamber 5 flow into the hollow yarns being built in the oxygen-adding region 3 and the nitrogen monoxide- adding region 4 respectively. Then, gases are exchanged with blood on the outside of the hollow yarns through a film surface, and excessive oxygen and nitrogen monoxide, which have not been dissolved with the blood, are discharged into the atmosphere from the gas current outlets 32 and 42 respectively. |
