Abstract
Abstract In a breathing apparatus of the kind which fits inside the mouth in the side of the mouth between the teeth and cheek, being comprised of an elongated air-flow tube which conveys respirated air from the front of the mouth to the rear portion of the mouth proximate the molar teeth, an improvement is disclosed which is defined by a longitudinally extending stabilizing fin affixed to the breathing tube. The stabilizing fin is adapted to fit primarily between the gum and cheek and serves to prevent unwanted expulsion of the breathing apparatus from the mouth and further functions in maintaining the positioning of the air openings of the tube relative to the teeth, cheek and lips of the user of the apparatus.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
184 words
In a breathing apparatus of the kind which fits inside the mouth of a human between cheek and teeth, which kind has tube means for air flow, said tube means having at least one upstream air opening proximate the lips, said tube means adapted and being of a length sufficient to extend from the front of the mouth back down the side of the mouth between cheek and teeth to the rear of the mouth adjacent the molars, said tube means having at least one downstream air opening adapted to communicate the interior of said tube means with said rear of said mouth, said downstream air opening being located at a point adjacent the molars, with said upstream opening in combination with said downstream opening being sized to permit a flow of respirated air through said tube means approximate the flow of air said human could achieve through normal nasal breathing; an improvement comprising stabilizing means affixed and extending laterally from said tube means, said stabilizing means being adapted to fit between the cheek and jaw gum and adapted to contact the jaw gum.
Claim 2
Dependent Claim
184 words
In a breathing apparatus of the kind which fits inside the mouth of a human between cheek and teeth, which kind has tube means for air flow, said tube means having at least one upstream air opening proximate the lips, said tube means adapted and being of a length sufficient to extend from the front of the mouth back down the side of the mouth between cheek and teeth to the rear of the mouth adjacent the molars, said tube means having at least one downstream air opening adapted to communicate the interior of said tube means with said rear of said mouth, said downstream air opening being located at a point adjacent the molars, with said upstream opening in combination with said downstream opening being sized to permit a flow of respirated air through said tube means approximate the flow of air said human could achieve through normal nasal breathing; an improvement comprising stabilizing means affixed and extending laterally from said tube means, said stabilizing means being adapted to fit between the cheek and jaw gum and adapted to contact the jaw gum.
Claim 3
Dependent Claim
17 words
The improvement of claim 1 wherein said stabilizing means is a fin-like projection from said tube means.
Claim 4
Dependent Claim
18 words
The improvement of claim 1 wherein said stabilizing means is moveable along the length of said tube means.
Claim 5
Dependent Claim
187 words
In a breathing apparatus of the kind which fits inside the mouth of a human between cheek and teeth, which kind has tube means for air flow, said tube means having at least one upstream opening proximate the lips, said tube means being adapted and of a length sufficient to extend from the front of the mouth back down the side of the mouth between cheek and teeth to the rear of the mouth adjacent the molars, said tube means having at least one downstream air opening adapted to communicate the interior of said tube means with said rear of said mouth, said downstream air opening being located at a point adjacent the molars, with said upstream air opening in combination with said downstream opening being sized to permit a flow of respirated air through said tube means approximate the flow of air said human could achieve through normal nasal breathing; an improvement comprising wire-like stabilizing means affixed to and extending laterally from said tube means, said wire-like stabilizing means being adapted to fit between the cheek and jaw gum and adapted to contact the jaw gum.
Claim 6
Dependent Claim
187 words
In a breathing apparatus of the kind which fits inside the mouth of a human between cheek and teeth, which kind has tube means for air flow, said tube means having at least one upstream opening proximate the lips, said tube means being adapted and of a length sufficient to extend from the front of the mouth back down the side of the mouth between cheek and teeth to the rear of the mouth adjacent the molars, said tube means having at least one downstream air opening adapted to communicate the interior of said tube means with said rear of said mouth, said downstream air opening being located at a point adjacent the molars, with said upstream air opening in combination with said downstream opening being sized to permit a flow of respirated air through said tube means approximate the flow of air said human could achieve through normal nasal breathing; an improvement comprising wire-like stabilizing means affixed to and extending laterally from said tube means, said wire-like stabilizing means being adapted to fit between the cheek and jaw gum and adapted to contact the jaw gum.
