The windpipe tube, the rectilinear part which from the buckling part and the buckling part which it adjoins to that distance destal extends to the proximal destal of the windpipe tube and, to have the mask which is loaded onto the distance destal of the windpipe tube and the windpipe tube which possess the proximal destal and the distance destal and, in the artificial windpipe which it has, the buckling part shift than the rectilinear part.近位端部および遠位端部を有する気道管と、気道管の遠位端部に搭載されたマスクと、を備えた人工気道において、気道管は、その遠位端部に隣接する湾曲部分と、その湾曲部分から気道管の近位端部に延びる直線部分と、を備え、湾曲部分は直線部分より硬い。
