PROBLEM TO BE SOLVED: To provide a tracheal tube having a suction lumen which can easily suck and remove foreign matters such as phlegm even for a patient who is lying down.SOLUTION: A tracheal tube comprises a tube body where a tip end part and a base end part are connected to each other through a curved part, and a cuff attached on the outer peripheral surface of the tube body. A suction lumen extending along a center axis on the inner peripheral surface of the tube body communicates with the outward of the tube body through a suction port which penetrates from an inner wall opening formed on the inner wall of the suction lumen to an outer wall opening formed on the outer peripheral surface at a position on the side closer to the base end part than the cuff. If a plane including the center axis is a first virtual plane, the inner wall opening, on a cross section orthogonal to the center axis and including the inner wall opening, is formed on the side of a lower surface part with respect to a second virtual plane passing through the center axis on the cross section and orthogonal to the first virtual plane, and at a position which does not intersect the first virtual plane and the second virtual plane.SELECTED DRAWING: Figure 10 |
