PROBLEM TO BE SOLVED: To provide a tracheal tube capable of easily removing a foreign matter such as a sputum adhered to the inside of a tube body even when the tube has a curved shape having a curved part between a distal end part and a base end part.SOLUTION: A tracheal tube inserted into a trachea of a human body comprises: a tube body having a substantially circular cross section, in which a distal end part and a base end part are connected through a curved part; and an inner cylindrical body formed in a cylindrical shape and covering at least a part of an inner face of the tube body. The inner cylindrical body has a weakened part for cutting, which extends from one end toward the other end. By cutting off the weakened part for cutting, the inner cylindrical body can be peeled from the inner face of the tube body and removed to the outside of the tube body.SELECTED DRAWING: Figure 3 |
