A medical airway instrument (1) is provided which is capable of facilitating creation of an air passage in the larynx to prevent collapse of the root of a patient's tongue, and having a lingual strip (2) curved in a longitudinal direction to conform with curvature of the tongue and palatal strip (3) curved in roughly the same manner as the lingual strip (2) such that the palatal and lingual strips (2,3) overlap in the anterior direction of curvature. The lingual and palatal strips (2,3) are rotatably coupled by a spindle (5) in the vicinity of a posterior part (2b, 3b) thereof. A stopper (4) is provided on a side of the lingual strip (2) to project in the direction of overlapping, in a position forward of the spindle (5) to hold anterior parts (2a, 3a) of the lingual and palatal strips (2,3) apart from one another at any desired gap without contact therebetween, to thereby secure a breathing passage (10) between the strips (2,3). |
