PROBLEM TO BE SOLVED: To provide a device for differential lung ventilation that can retain an inserted position of a tube for differential lung ventilation into a living body and adjust the position as necessary.SOLUTION: The device includes: the tube 2 for differential lung ventilation that can individually ventilate right and left lungs of a patient J by expanding a bronchial cuff 6 and a bronchial cuff 5 in a state that a tube body 4 is inserted into the patient J and a slider 3 that can be fixed to the patient J in a state that the tube body 4 is inserted into the patient J, and can switch a retained state of the tube body 4 from a restricting state that restricts the movement of the tube body 4 to the patient J in an insertion/extraction direction into a permitted state that permits the movement of the tube body 4 in the insertion/extraction direction.COPYRIGHT: (C)2013,JPO&INPIT【課題】分離肺換気用チューブの生体に対する挿入位置を保持するするとともに、必要に応じて調整することができる分離肺換気用具を提供すること。【解決手段】チューブ本体4を患者Jに挿入した状態で気管支用カフ6及び気管用カフ5を膨張させることにより患者Jの左右の肺を分離して換気可能な分離肺換気用チューブ2と、前記チューブ本体4が患者Jに挿入された状態で患者Jに固定可能で、かつ、チューブ本体4の患者Jに対する挿抜方向の移動を規制する規制状態とチューブ本体4の挿抜方向の移動を許容する許容状態との間でチューブ本体4の保持状態を切換可能なスライダ3とを備えている。【選択図】図1
