US 12,214,131 B2 · Lower jaw and tongue thrusting, endotracheal tube and flexible fiberoptic endoscope intubation oral airway device

Abstract

A lower jaw and tongue thrusting endotracheal tube and flexible fiberoptic endoscope intubation oral airway device having an elongated body including, a mandible flange with a lingual flat portion transversely disposed on a ventral surface of a tongue plate. The device having an open top toward the palate like a rectangular trough. The trough extends through the device from the proximal end to the front middle part of the tongue plate. The device includes an L-shaped insert that slideably couples between the upper lip flanges and acts also as dorsal surface of the bite block. The distal end of the tongue plate end comprises a curved surface which tapers to a narrow distal edge. A pair of upstanding walls attach to the tongue faceplate ventral surface edges which taper as they extend posteriorly. The walls ensure protection for medical instruments disposed within the flexible fiberoptic endoscope guide.

Dependent claims

A lower jaw and tongue thrusting endotracheal tube and flexible fiberoptic endoscope intubation (LJT-ET-FO) oral airway device, comprising

an elongate member having a distal end and a proximal end, the elongate member sized for insertion in the mouth of a patient and facilitation of air and medical instrument passage between the proximal and distal ends, including:
a flange assembly located at the proximal end of the elongate member including a lower lip flange, a pair of upper lip flanges, and a sliding insert that removably couples the pair of upper lip flanges, the sliding insert including a maxillary engagement surface that defines an upper cover of a passageway extending into the elongate member;
a tongue plate extending to the distal end of the elongate member;
a trough extending between the flange assembly and the tongue plate;
a mandibular flange projecting downwardly and transversely disposed at a first proximal end of the trough;
wherein the mandibular flange has a proximally facing surface that is located proximal to the maxillary engagement surface of the sliding insert but distal to the lower lip flange.

A lower jaw and tongue thrusting endotracheal tube and flexible fiberoptic endoscope intubation (LJT-ET-FO) oral airway device, comprising:

a semi-rigid, semi-rectangular, elongate member with two lateral walls extending from a flat ventral base with an open top lumen, the elongate member extending from a proximal end that includes an upper lip flange, a lower lip flange, and a bite block to a distal end having structure for location adjacent the root of the tongue of a patient including a tongue plate;
wherein the bite block partially defines a passageway between a pair of spaced apart lip flange projections that comprise the upper lip flange and the lower lip flange;
wherein the bite block has a ventral surface with a mandibular flange in vertical alignment with the upper lip flange but distal to the lower lip flange, the mandibular flange configured to be placed behind mandibular incisor teeth of the patient to hold the lower mandibular jaw and the tongue of the patient as the lower jaw is thrust forward into position;
wherein the bite block has a resilient, teeth and lip engaging part on the ventral surface between the lower lip flange and the mandibular flange for placing lower incisor teeth and lower lip for maintaining a protracted mandibular position;
and
wherein the ventral surface of the bite block angles inferiorly towards the lower lip flange.
