The upper teeth support surface 110 and the lower teeth support surface 120 support the upper teeth and the lower teeth, respectively, and are formed as flat surfaces and arc-shaped.

The upper teeth support surface 110 and the lower tooth support surface 120 are designed as a mandibular anterior lugging so that the mandible is directed forward when the patient's upper and lower jaws are engaged to maintain the airway and prevent the tongue from drying .

The center block 150 is formed between the upper teeth support surface 110 and the lower tooth support surface 120. The central block 150 is provided with a through hole 160 passing through in the front and back direction, (Not shown).

The through-hole 160 is used for inserting or removing a suction device for removing foreign substances in the oral cavity or for use in or exiting the endoscope instrument.

In the illustrated embodiment, the through-hole 160 is positioned on the left side and the airway tube fixing hole 170 is positioned on the right side. Alternatively, the through-hole 160 is positioned on the right side, Or the like. In the present invention, the airway tube fixing hole 170 and the through hole 160 for the suction or endoscope are separately formed to perform the necessary operation without moving the airway tube fixed to the airway tube fixing hole 170 To be able to do.

The airway tube fixing hole 170 is for immovably fixing the airway tube and is connected to the incision 180 so as to facilitate insertion of the airway tube.

A concave groove 182 is formed at the side of the central block 150 at the beginning of the incision 180 so as to be recessed at the center of the incision 180. This structure allows the mouthpiece to be laterally pushed into the airway tube fixing hole 170 after the side of the airway tube is positioned in the concave groove 182 with the airway tube inserted into the patient's mouth .

Further, the airway tube fixing hole 170 is formed with fixing protrusions 172 extending upward and downward to face each other. A spacing is formed between the fixing projections 172.

The fixing protrusions 172 serve to stably fix airway tubes of various sizes to the airway tube fixing holes 170.
