MEDICAL BREATHING APPARATUS
First Claim
1. A medical mouthpiece, comprising:
- a generally U-shaped first member having a tubular portion extending anteriorly therefrom, the first member including an upper surface configured to contact an upper dentition of a patient spaced apart from a lower surface configured to contact a lower dentition of the patient;
wherein the first member includes a posterior central orifice extending anteriorly to posteriorly through the first member along a medial line;
wherein the first member forms at least one lateral interocclusal passageway extending anteriorly to posteriorly through the first member between the upper surface and the lower surface; and
a second member slidably received within the tubular portion, the second member including a perimeter ring defining an outwardly-facing surface configured to be in facing engagement with an inner surface of the tubular portion;
wherein the second member includes an anterior central orifice extending anteriorly to posteriorly through the second member along the medial line, the anterior central orifice cooperating with the posterior central orifice to form a central passageway extending through the mouthpiece;
wherein the second member includes one or more anterior apertures and at least one lateral interocclusal passageway passing through the perimeter ring anteriorly to posteriorly from the one or more anterior apertures.

Abstract
A medical mouthpiece may include a U-shaped first member having a tubular portion, the first member forming at least one lateral interocclusal passageway extending through the first member, and a second member received within the tubular portion. A medical breathing apparatus may include a U-shaped first member forming left and right lateral interocclusal passageways extending through the first member, a second member attached to the first member, and an adapter receivable within a tubular portion of the first member, wherein the adapter includes a respiratory orifice configured to deliver respiratory gas to the left and right lateral interocclusal passageways. A method for delivering positive pressure and/or a respiratory gas to a patient may include inserting a mouthpiece into a mouth of the patient, and delivering the positive pressure and/or the respiratory gas through the mouthpiece to a space adjacent a posterior oropharynx of the patient.

13. A medical breathing apparatus, comprising:
-
a generally U-shaped first member forming an upper surface spaced apart from a lower surface with left and right lateral interocclusal passageways formed therebetween, the left and right lateral interocclusal passageways extending from an anterior portion of the first member through a posterior portion of the first member, and a posterior central orifice extending through the anterior portion from a first cavity defined by a tubular portion extending anteriorly from the anterior portion of the first member; wherein the first member is shaped and configured to contact an upper dentition of a patient with the upper surface or a lower dentition of a patient with the lower surface; a second member attached to the anterior portion, the second member including an anterior central orifice extending through the second member and in communication with the posterior central orifice to form a central passageway extending through the first member and the second member; wherein the second member includes one or more anterior apertures in fluid communication with the left and right lateral interocclusal passageways; and an adapter slidably receivable within the first cavity of the tubular portion of the first member, wherein the adapter includes a central orifice configured to engage the second member as an extension of the central passageway, and a respiratory orifice configured to deliver respiratory gas to the left and right lateral interocclusal passageways. - View Dependent Claims (14, 15, 16)
