PROBLEM TO BE SOLVED: To provide a tracheal tube with which safety can be increased.SOLUTION: The tracheal tube comprises: a tube body 2 and a cuff 3 which includes a barrel 16 contractible and expandable in a radial direction of the tube body, and which includes a distal side connection 14a and a proximal side connection 14b respectively adjacent to both sides of the barrel in a center axis direction of the tube body, and fixed to an outer wall of the tube body. In a cross section containing a center axis O1, a length L1 in a center axis direction between a position at which the barrel and the distal side connection are adjacent to each other and a position at which the barrel and the proximal side connection are adjacent to each other is shorter than the maximum length L2 in the center axis direction of the barrel.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2017,JPO&INPIT【課題】安全性を向上可能な気管チューブを提供する。【解決手段】チューブ本体2と、チューブ本体の径方向に収縮及び拡張可能な胴部16、並びに胴部のチューブ本体の中心軸線方向における両側それぞれで連続し、チューブ本体の外壁に固定される先端側接続部14a及び基端側接続部14b、を有するカフ3と、を備え、中心軸線O1を含む断面において、胴部と先端側接続部とが連続する位置と胴部と基端側接続部とが連続する位置との間の中心軸線方向における長さL1は、胴部の中心軸線方向における最大長さL2よりも短い。【選択図】図4
