PROBLEM TO BE SOLVED: To provide a tracheal tube capable of easily removing a foreign matter such as a sputum adhered to an inner face even when the tube has a curved shape having a curved part between a distal end part and a base end part.SOLUTION: A tracheal tube inserted into a trachea of a human body comprises: an outer tube having a substantially circular cross section, in which a distal end part and a base end part are connected through a curved part an inner tube accommodated inside the outer tube so as to be relatively rotatable around an axial center of the outer tube and a rotation operation part protruding from a base end of the outer tube to the outside and rotating with the inner tube.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2016,JPO&INPIT【課題】先端部と基端部との間に湾曲部を有する曲がった形状であっても内面に付着した痰等の異物を容易に除去することができる気管チューブを提供する。【解決手段】人体の気管に挿入される気管チューブであって、湾曲部を介して先端部と基端部とが繋がっている断面略円形の外管と、前記外管の内側に該外管の軸心を中心として相対回転自在に収容された内管と、前記外管の基端から外部に突出して設けられ、前記内管とともに回転する回転操作部と、を有することを特徴とする。【選択図】図3
