Abstract

The present invention provides an oral device that is inserted into the mouth of a patient during sedation to minimize the risk of airway obstruction and method of use. The oral device comprises a mouthpiece. A gas inlet conduit, a gas outlet conduit, and a fluid outlet conduit are adjacent to the vestibular portion of the mouthpiece. The gas inlet conduit may be used to provide oxygen to the mouth of a patient. The gas outlet conduit may be used to remove end-tidal carbon dioxide from the mouth of a patient. The fluid outlet conduit may be used to remove fluid from the mouth of a patient. The oral device may also include a tongue stabilizer to minimize movement of the tongue. The mouthpiece may include fluid outlet ports to remove fluid from the mouth of a patient and an instrument passage to allow medical instruments to pass through the oral device.

Dependent claims

An oral device comprising:

a mouthpiece configured for insertion into a mouth, said mouthpiece having a vestibular portion, an oral cavity portion, an upper portion and a lower portion, wherein said upper portion is configured to hold upper teeth of said mouth and said lower portion is configured to hold lower teeth of said mouth, and wherein the vestibular portion comprises an outer portion of the mouthpiece that faces cheeks and lips when the mouthpiece is inserted into the mouth, and wherein the vestibular portion comprises a top vestibular portion for the upper portion of the mouthpiece and a bottom vestibular portion for the lower portion of the mouthpiece;
a gas inlet conduit adjacent to and extending directly along a first side of said top vestibular portion of said mouthpiece, wherein said gas inlet conduit has a first opening configured to be outside said mouth and a second opening configured to be inside said mouth and is configured to allow gas to flow from said first opening to said second opening of said gas inlet conduit;
a gas outlet conduit adjacent to and extending directly along a second side of said top vestibular portion of said mouthpiece, wherein said gas outlet conduit has a first opening configured to be outside said mouth and a second opening configured to be inside said mouth and is configured to allow gas to flow from said second opening to said first opening of said gas outlet conduit;
and,
a saliva outlet conduit directly adjacent to said bottom vestibular portion of said mouthpiece, wherein said saliva outlet conduit has a first opening configured to be outside said mouth and a second opening configured to be inside said mouth and is configured to allow saliva to flow from said second opening to said first opening of said saliva outlet conduit.
