<p><P>PROBLEM TO BE SOLVED: To provide an instrument capable of preventing damage to a maxillary anterior tooth by a laryngoscope and keeping a stable mounting state in which a device that is put on does not fall from a tooth, in a tooth protective device for tracheal intubation used by being put on the tooth during the tracheal intubation. <P>SOLUTION: For a device body 1, a cross section is turned to a recessed shape so as to be put on a maxillary dental arch, the whole is formed into a U shape opened at both ends, and the height of a wall part 11 abutted on a dentition surface side is formed to be larger on a front tooth side than on a molar side. Also, the device body 1 includes a projection 2 provided on a part for holding an upper labial frenulum when put on the dentition, a flange-like overhang 3 provided on a part positioned between a front tooth distal end and an upper lip, and a grid-like rib 4 provided on a part to protect the front tooth distal end, and the tooth abutting surface 11B of a tooth surface side wall part 11 is formed by being inclined to the inner side at an angle equal to or larger than 75°and equal to or smaller than 85°to the surface of a bottom part 13. Further, a curve suited to the maxillary dental arch is formed to be variable. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
