PROBLEM TO BE SOLVED: To provide a tracheal tube with which safety can be increased.SOLUTION: Provided is a tracheal tube 1, comprising: a tube body 2 and a cuff 3 which is mounted to the tube body 2, and of which barrel is contractible and expandable. The tracheal tube includes: a sealed part 31 at which a covering region 30 for covering a tracheal inner wall of a trachea when the barrel is expanded inside the trachea continuously contacts the tracheal inner wall along a circumferential direction of the barrel and a wrinkle part 32 which appears on a cross section obtained by cutting the covering region 30 along an arbitrary plane orthogonal to the center axis of the tube body 2.SELECTED DRAWING: Figure 5COPYRIGHT: (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2に装着され、胴部が収縮及び拡張可能なカフ3と、を備え、胴部が気管内で拡張した状態において気管の気管内壁を被覆する被覆領域30が、胴部の周方向に亘って連続して気管内壁と接触する密閉部31と、被覆領域30をチューブ本体2の中心軸線に直交する任意の面で切断した断面に表れるしわ部32とを有する、気管チューブ1。【選択図】図5
