The present disclosure relates generally to an oral appliance and to methods of using such a device. More particularly, the disclosure relates to a device including an inflatable balloon and a guide assembly. One aspect of the present disclosure provides an oral device including an elongated member extending from a proximal end to a distal end, and an inflatable balloon attached to the elongated member near the distal end, the inflatable balloon having a central lumen. Another aspect provides a method of intubating a patient using an oral appliance as disclosed herein.

The present invention discloses a new and improved endoscopic-enabled mouth gag for routine ENT procedures, such as adenoidectomy and nasopharyngeal biopsy. The invention modifies the existing mouth gag, provides a stable and adjustable placement for an endoscopic device potentially employed during an ENT procedure, and is to replace the outdated surgical method where the surgical field is visualized indirectly via a handheld mirror (with or without the preexisting mouth gag). The inventive endoscopic-enabled mouth gag not only provides enhanced visualization of the surgical field for a clinician, assistants, and trainees, but also enables a clinician to perform the procedure bimanually (with both hands).

A bite block to assist with upper Gastrointestinal (GI) endoscopy procedures. A main body of the bite block employs a rectangular shaped lumen to provide a large access port for insertion of variety of endoscopes and endoscopy equipment, individually or multiple instruments at the same time, and to guide them more precisely into the esophagus. The main body having a lumen shaped with respect to the anatomy of the oral cavity, where a curvature of the body is designed to act as a tongue depressor preventing airway blockage due to tongue collapse. Assigned channels run along the entire length of the device and are used to secure tubing in place for oxygen and monitor maximal concentration of carbon dioxide.

An oral medical apparatus includes a flexible tube with a first portion adjacent a proximal end of the tube and a second portion adjacent to the first portion. A support is located within the upper portion to prevent compression or collapse of the upper portion of the tube. The oral medical apparatus can accommodate a rigid connector that may be directly coupled to an anesthesia breathing circuit or a medical breathing device.

A respiratory interface, such as a mouthpiece having a vestibular shield overlapping a user's teeth and gums, gases passageway extending through the vestibular shield allowing for the passage of the gases through mouthpiece and an extra oral seal associated with the gases passageway, wherein the passageway in use causes gases to be diffused when exiting from the gases passageway. Mouthpiece may have an adjustment mechanism to alter distance between the vestibular shield and the extra-oral seal. The interface may include an elbow having a vent.

Using various embodiments, methods and systems for a respiratory airway assistive device are described. In one embodiment, the device includes an airway maintenance body comprising an dorsal surface and an ventral surface, a first end, a first aperture having a first opening positioned at or near the first terminus, a second end, a second aperture positioned at or near the second terminus and that is in fluidic communication with the first aperture, wherein the first end is configured to be accommodated inside the mouth of a human subject, and wherein the second end is configured to be outside the mouth, and wherein the first end includes a curvature, the curvature at the ventral surface accommodating a cavity. The device further includes a vestibular guard coupled to the airway maintenance body forming an occlusal rest portion on the dorsal surface or the airway maintenance body.

Disclosed is an apparatus and method to facilitate insertion of the endotracheal tube into the patient's trachea.

An intubation assembly and shield configured to at least partially reduce the risk of contagion of airborne illnesses. The intubation assembly comprises an intubation apparatus assembly, which may comprise an intubation apparatus such as a laryngoscope, endoscope, bronchoscope, or other fiberoptic device. The intubation apparatus assembly may be operatively disposed on the shield assembly. The intubation apparatus may be placed on a correspondingly dimensioned sleeve. The shield assembly comprises a body with a plurality of side segments and a first transparent component with a shield opening disposed thereon. The shield opening may be used for insertion of the intubation apparatus assembly. The shield assembly may also comprise a second transparent component with at least one longitudinally disposed slot for insertion of an endotracheal tube or other intubation apparatus(es). The shield assembly may be provided with ports to attach a vacuum device to provide negative pressure.

An oral device includes an intraoral bolus simulator comprising an exterior surface and having an interior volume Tillable with a fluid. An extraoral user interface extends from the bolus simulator, and can be used to locate or position the intraoral bolus simulator. In various embodiments, the fluid may be a gas or a liquid, or combinations thereof. In other embodiments, an oral device includes an extraoral handle, a shield connected to the handle, a tether extending from the shield, and a bolus simulator connected to the tether.

A sleep apnea device includes a bite block, a plurality of receivers coupled to a lingual surface of the bite block, a plurality of transition pieces corresponding to the plurality of receivers. Each transition piece may include a vertical portion coupled to a corresponding receiver of the plurality of receivers, a horizontal portion configured to extend from the vertical portion, and a dam securing member fixed to one of the vertical portion, the horizontal portion, or both the vertical portion and the horizontal portion. The device may also include a plurality of base connectors corresponding to the plurality of transition pieces, a base coupled to the plurality of base connectors, and a resilient dam configured to be releasably secured by each dam securing member of the plurality of transition pieces. A kit including the sleep apnea device is also disclosed.
