Tracheal intubation guide apparatus and tracheal intubation guide kit comprising same

1 . A tracheal intubation guide apparatus comprising:

a longitudinally curved cylindrical case capable of being inserted into an oral cavity,

wherein the case has an endotracheal tube insertion hole on a proximal side, an endotracheal tube discharge hole on a distal side, and a longitudinally curved tracheal intubation guide passage connecting the endotracheal tube insertion hole and the endotracheal tube discharge hole, and a tooth clasp is provided on the proximal side of the case,

wherein the case forms a downward curve from the proximal side to a center and an upward curve from the center to the distal side,

wherein the case includes a first case body forming a right half of the case and a second case body forming a left half of the case, the first case body and the second case body being coupled by one or more magnets configured to allow coupling and decoupling,

wherein the tooth clasp being positioned to have a centerline thereof located between a 31st tooth and a 41st tooth at a center of a mandible of an operation subject to place a distal exit of the guide passage immediately in front of an entrance of a trachea,

wherein one side of the distal end of the case is provided with a laryngeal cover clasp protruding from the case, the laryngeal cover clasp being configured to push an epiglottis upward to expose the trachea,

wherein the other side of the distal end of the case is provided with an esophageal insertion prevention plate protruding farther from the case than the laryngeal cover clasp to prevent insertion into the esophagus, and

wherein the endotracheal tube discharge hole is located in an area between the laryngeal cover clasp and the esophageal insertion prevention plate,

further comprising a handle;

wherein each of the first case body and the second case body includes a handle coupler positioned on a rear surface side of the tooth clasp; and

wherein the handle, the first case body, and the second case body are fastened to be coupled to and decoupled from each other at the handle coupler by a single screw passing through the handle and engaging the handle couplers of the first and second case bodies.

2 . A tracheal intubation guide kit comprising:

the tracheal intubation guide apparatus according to claim 1 ; and

a manual for using the tracheal intubation guide apparatus,

wherein the manual includes instructions for an operator to put and fix the tracheal intubation guide apparatus in an oral cavity of an operation subject, pass an endotracheal tube along the tracheal intubation guide passage of the tracheal intubation guide apparatus, and then decouple the first case body from the second case body of the tracheal intubation guide apparatus or the first case body, the second case body, and the handle from each other.

3 . The tracheal intubation guide kit according to claim 2 ,

wherein the tracheal intubation guide apparatus further includes the tooth clasp on the proximal side of the case, and

wherein the manual further includes an instruction to place the tooth clasp on teeth of the operation subject to have the centerline of the tooth clasp located between the 31st tooth and the 41st tooth at a center of a mandible of the operation subject.
