Respiratory mask having intraoral mouthpiece with large sealing area and multiple sealing configuration
First Claim
1. A respiratory mask, comprising:
- an intraoral mouthpiece comprising;
a substantially oval and bowed sheet of material having an inner surface, an outer surface, a top portion, a bottom portion, an upper edge, and a lower edge;
a central orifice through the approximate center of the substantially oval and bowed sheet of material;
a tubular extension having a proximal end, a distal end, and a conduit, wherein the conduit of the tubular extension at the proximal end of the tubular extension feeds into the central orifice of the intraoral mouthpiece, the proximal end of the tubular extension terminating substantially coextensive with the inner surface of the sheet of material; and
a reinforced collar surrounding a portion of the tubular extension; and
wherein the substantially oval and bowed sheet of material is configured to fit between gums and lips of a person, extending upward and downward substantially parallel to the gums and teeth of the person beyond the gumline of the person, and extending posteriorly in the mouth of the person.

Abstract
A respiratory mask provides improved sealing through the use of an intraoral mouthpiece with a large sealing area. A tubular extension, configured at one end to accept standard respiratory fittings, is the conduit for gas delivery to the intraoral mouthpiece. The respiratory mask may also include an intraoral oropharyngeal airway which flexes so that it can be inserted without the need for rotation or use of a tongue blade. The respiratory mask may also include an external shield to enhance sealing and provide a barrier of protection for the healthcare provider. The mask'"'"'s design allows for a novel handgrip technique that allows a single healthcare provider to ventilate with enhanced sealing.

24. A respiratory mask, comprising:
-
a substantially bowed, intraoral mouthpiece comprising an inner surface, an outer surface, a top portion, a bottom portion, an upper edge, and a lower edge, the mouthpiece extending between a first lateral edge and a second lateral edge, the mouthpiece defining a central orifice through an approximate center of the first and second lateral edges; and
a tubular extension having a proximal end, a distal end, and a conduit, wherein the conduit of the tubular extension at the proximal end of the tubular extension feeds into the central orifice of the mouthpiece, the proximal end of the tubular extension terminating substantially coextensive with the inner surface of the mouthpiece;
wherein the mouthpiece is configured to fit between a person'"'"'s gums and lips, extends upward and downward substantially parallel to the gums and teeth of the person, and extends posteriorly in the person'"'"'s mouth. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)

37. A respiratory mask, comprising:
-
a substantially bowed, intraoral mouthpiece comprising an inner surface, an outer surface, a top portion, a bottom portion, an upper edge, and a lower edge, the mouthpiece extending between a first lateral edge and a second lateral edge, the mouthpiece defining a central orifice through an approximate center of the first and second lateral edges; and
a tubular extension having a proximal end, a distal end, and a conduit, wherein the conduit of the tubular extension at the proximal end of the tubular extension feeds into the central orifice of the mouthpiece;
wherein the mouthpiece is configured to fit between a person'"'"'s gums and lips, extends upward and downward substantially parallel to the gums and teeth of the person, and extends posteriorly in the person'"'"'s mouth; and
wherein a first lateral portion of the mouthpiece between the central orifice and the first lateral edge provides lateral flexibility, and a second lateral portion of the mouthpiece between the central orifice and the second lateral edge also provides lateral flexibility, thereby facilitating introduction and removal of the mouthpiece from the patient'"'"'s mouth. - View Dependent Claims (38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49)
