Claims

[Claims for Utility Model Registration] (1) A curved outer tube in which a communication hole is formed in the tube wall to communicate between the inside and outside of the tube, and a curved inner tube in which a portion of the tube is removably inserted into the curved outer tube; a telescopic cuff having both ends tightly fitted to the outer periphery of one end of the curved outer tube from the communication hole; a plate-shaped protector attached to the outer periphery of the other end of the curved outer tube; a curved inner tube lock mechanism releasably provided between the other end and the other end of the curved inner tube inserted into the curved outer tube; and a cuff inflation means communicated with the inside of the cuff via a tube; A tracheostomy tube comprising a secretion suction means communicating with a tube opening in the vicinity of the cuff on the communication hole side of the curved outer tube. (2) Detachably attachable to the other end of the curved outer tube to prevent exhaled air from flowing from the curved outer tube toward the atmosphere through intake air into the curved outer tube in a state in which the curved inner tube is extubated from the curved outer tube. check valve or said intake;
The tracheostomy tube according to claim 1, characterized in that a perforated lid for regulating exhalation or a stopper for preventing said inhalation and exhalation is attached. (3) A curved outer tube in which a communication hole is formed in the tube wall to communicate between the inside and outside of the tube, a curved inner tube in which a portion of the tube is removably inserted into the curved outer tube, and a portion of the curved outer tube that extends from the curved outer tube to the curved inner tube. When the tube is extubated, a check valve is provided which is detachably attached to the other end of the curved outer tube and prevents exhaled air from flowing into the curved outer tube and from the curved outer tube toward the atmosphere; a perforated lid for regulating or a stopper for blocking the intake and exhalation; a plate-shaped protector attached to the outer periphery of the other end of the curved outer tube; An endotracheal incision tube comprising a curved inner tube locking mechanism releasably provided between the curved inner tube and the other end of the curved inner tube.
