| Abstract: |
A breathing apparatus is disclosed which fits into the mouth of a human between the teeth and cheeks. The apparatus functions to direct air from the front of the mouth to the back of the mouth and from there to the lungs. The apparatus features a ported curved tube which is open-ended and which has sufficient length to extend from the rear of the mouth on one side of the mouth along a path following the tooth line from one set of molars to the other and on to the rear of the mouth on that other side of the mouth. To facilitate flow of air from the front of the mouth to the rear, there is provided an intake opening located midway the tube so that said opening will be in a position at the front of the mouth. Exhaust openings are provided in conjunction with each open end of the apparatus for allowing passage of the air from the tube into the rear of the mouth and upper trachea. The intake and exhaust openings together with the cross-sectional area of the curved tube are designed so that when the user is breathing through the apparatus, the flow of air therefrom will be approximate to that flow of air as could be expected with normal nasal breathing.

What is claimed:
1. A breathing apparatus fitable into the mouth of a human between cheeks and teeth which apparatus includes:
- a. flexible curved tube means being open-ended and having sufficient length to extend along a path following the tooth line from a point adjacent one set of molars to a point adjacent the other set of molars;
- b. at least one intake opening located midway said curved tube means so that said intake opening will be positioned towards the outside of the mouth and proximate to the middle of said mouth; and,
- (c) at least one exhaust opening in each side of said curved tube means adapted to face the inside of said mouth, proximate the open ends of said curved tube and located at a point above the lower-most point of said curved tube means, said intake and said exhaust openings being, in combination with the cross-sectional area of said curved tube means, a size sufficient to allow a flow of air through said curved tube approximate to the flow of air that said human could achieve through normal nasal breathing.
