Claims

[Claims for Utility Model Registration] 1. A balloon provided near the distal end of a tube body having a lumen communicating with the distal opening, and an airway fluid having an opening in the circumferential wall of the tube body behind the balloon. In an endotracheal tube in which a small lumen for suction is provided in the tube body along the lumen, the small lumen for suctioning airway fluid communicates with the small lumen at a position on the distal end side of the tube body from the opening of the small lumen. An endotracheal tube characterized in that a small lumen for introducing air is provided in the tube body along the lumen. 2. In the endotracheal tube according to claim 1, the small lumen for suctioning intratracheal fluid and the small lumen for introducing air are provided in a tube body separate from the tube body, and the tube body extends in the longitudinal direction of the tube body. An endotracheal tube characterized in that it is fixed to the outer peripheral surface of the tube.
