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.
