PROBLEM TO BE SOLVED: To provide a tracheal tube capable of sucking and removing phlegm or the like in the trachea without placing any burden on a patient.SOLUTION: The tracheal tube includes: a distal end a proximal end at an opposite side of the distal end and a lumen body provided with an airway securing lumen. An end in the distal end side of the lumen body has a tapered shape, and the lumen body includes a suction lumen formed in a wall along the air securing lumen and opened into a tapered shape, where the suction lumen includes: a water-repellent membrane on a wall surface of the end part in the distal end side thereof and a hydrophilic membrane on the wall surface in the proximal end side with respective to the water-repellent membrane.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2018,JPO&INPIT【課題】患者に負担をかけずに気管内の痰等を吸引して除去できる気管用チューブを提供する。【解決手段】先端部、先端部の反対側となる基端部、および、気道確保用ルーメンが設けられた管腔体を有する気管用チューブであって、管腔体の前記先端部側の端部はテーパ状で、管腔体は、壁内に気道確保用ルーメンに沿って形成される、テーパ状部に開口する吸引ルーメンを有し、吸引ルーメンの先端部側の端部の壁面には撥水性皮膜を、撥水性皮膜より基端部側の壁面には親水性皮膜を、有することにより、課題を解決する。【選択図】図3
