PURPOSE:To prevent blocking the airway of a patient in the middle of general anesthesia or a coma by composing the above holder or upper and lower jaw supporting parts and a pair of connecting arms and forming the connecting arms so that they each can be bent in a springy way in a force direction by means of a force from both supporting part sides towards the connecting arm sides. CONSTITUTION:A connecting arm 3 connects opposite edges of an upper jaw supporting part 1 and a lower jaw supporting part 2 in a condition just to be bridged, and both supporting parts 1 and 2 are linked in a position to be opposed at a prescribed interval by means a pair of connecting arms 3 and 3. Since the connecting arm 3 is formed so as to be bent backward, the upper jaw supporting part 1 is fixed to an upper jaw, and thereafter, the lower jaw supporting part 2 can be fixed by being press-fitted in a lower jaw. After the lower jaw supporting part 2 is fixed, since a springing force, by which the connecting arm 3 intends to return to a former condition, works to the lower jaw supporting part 2 and lower jaw teeth are pressed forward by a rear wall 5b of a lower jaw teeth corresponding groove 5, the lower jaw is made to retreat, a tongue root is made to sink, and the air route can be prevented from being blocked. |
