PROBLEM TO BE SOLVED: To provide a tracheostomy tube device that enables a patient to more efficiently utter while reducing a burden on the patient.SOLUTION: A tracheostomy tube device includes a tracheostomy tube 2, a ventilator 3 and an utterance auxiliary device 4. The tracheostomy tube includes: a tube body having a respiratory air flow path inside an inflatable cuff provided in the tube body a cuff tube capable of injecting air into the cuff an air supply flow path for utterance capable of supplying air to the outside from an air supply port provided in the tube body and a tube for utterance connected to the air supply flow path for utterance. The ventilator alternately performs an inspiration operation for supplying the air into the respiratory air flow path and an exhalation operation for sucking the air from the respiratory air flow path. The utterance auxiliary device is connected to the air supply flow path for utterance through the tube for utterance, and supplies the air into the air supply flow path for utterance in conformity to the exhalation operation by the ventilator.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】患者への負担を減らしながらより効率よく発声することができる気管切開チューブ装置を提供すること。【解決手段】気管切開チューブ2と、人工呼吸器3と、発声補助機4とを備え、気管切開チューブが、内部に呼吸気用空気流路を有するチューブ本体と、チューブ本体に設けられ膨張可能なカフと、カフに空気を注入可能なカフ用チューブと、チューブ本体に設けられ送気口から外部に空気を送気可能な発声用空気供給流路と、発声用空気供給流路に接続された発声用チューブとを備え、人工呼吸器が、呼吸気用空気流路に空気を送り込む吸気動作と、呼吸気用空気流路から空気を吸引する呼気動作とを交互に行い、発声補助機が、発声用空気供給流路に発声用チューブを介して接続され、人工呼吸器による呼気動作に合わせて発声用空気供給流路に空気を送り込む。【選択図】図1
