TRACHEAL TUBE

Document Type and Number:

WIPO Patent Application WO/2016/129284

Kind Code:

A1

Abstract:

A tracheal tube is provided with: a tube body (2) in which a tip (8) and a base end (11) are connected via a curved section (10); and a cuff (3) fitted on the outer peripheral surface of the tube body (2). At a position closer to the base end (11) side than the cuff (3), a suction lumen (12), which extends along the central axis (O1) of the inner peripheral surface of the tube body (2), is connected to the outside through a suction opening (12b) that penetrates from an inner-wall opening (26) formed in the inner wall of the suction lumen (12) to an outer-wall opening (27) formed in the outer peripheral surface. The suction opening (12b) is formed such that, from the viewpoint of a point on the straight line connecting two third top parts (73) at which a first notch (61) and a second notch (62) intersect, a second angle, which is formed by a cross-section orthogonal to the central axis (O1) and a straight line connecting the third top parts (73) to a top part at which the second notch (62) intersects the outer peripheral surface, is smaller than a first angle, which is formed by a cross-section orthogonal to the central axis (O1) and a straight line connecting the third top parts (73) to a top part at which the first notch (61) intersects the outer peripheral surface.
