PROBLEM TO BE SOLVED: To provide a trachea tube to which phlegm is hardly adhered.SOLUTION: A trachea tube comprises: a tip end part arranged on a lung side in a trachea a base end part which is arranged on a side opposite to the tip end part and a lumen body having a lumen for airway maintenance which penetrates from the base end part to the tip end part. At least a part of the lumen body is formed of a moisture content permeable resin material, and on at least a part of an inner peripheral surface of the lumen body, a hydrophilic coating is formed. A portion of the lumen body formed of the moisture content permeable resin material can transmit the moisture content in a substance which is swallowed by mistake which contacts with an outer peripheral surface of the lumen body to an inner peripheral surface side of the lumen body, and the hydrophilic coating can hold a water layer on its surface by at least one selected from a moisture content in respiratory air which passes through the lumen body, moisture content included in phlegm which passes through the lumen body, and moisture content which transmitted to the inner peripheral surface side of the lumen body, in a non-immersion state.SELECTED DRAWING: NoneCOPYRIGHT: (C)2018,JPO&INPIT【課題】痰が付着しにくい気管用チューブの提供。 【解決手段】気管内の肺側に配置される先端部、先端部と反対側に設けられる基端部、および、前記基端部から前記先端部にかけて貫通する気道確保用ルーメンを有する管腔体と、を備える気管用チューブであって、前記管腔体の少なくとも一部は、水分透過性の樹脂材料で構成されており、前記管腔体の内周面の少なくとも一部に親水性皮膜が形成されており、前記水分透過性の樹脂材料で構成された管腔体の部位は、前記気管内において、前記管腔体の外周面と接触する誤嚥物中の水分を前記管腔体の内周面側に透過させることができ、前記親水性皮膜は、非浸漬状態において、前記管腔体内を通過する呼吸気中の水分、前記管腔体内を通過する痰に含まれる水分、および、上記管腔体の内周面側に透過した水分からなる群から選択される少なくとも一つにより、その表面に水層を保持することができることを特徴とする気管用チューブ。【選択図】なし
