| Abstract: |
A singularly compact inhalator-breathing apparatus is disclosed which fits inside the mouth of a human between the teeth and cheek and functions to controllably mix ambient air with other gases or gas-like material suspensions during the physiological process of inhaling and conveys the inhalant mixture to the rear of the mouth and on to the lungs. The apparatus is capable of transmitting either into or out of the mouth and lungs a flow of air approximate that flow of air which could be expected through normal nasal breathing.

What is claimed is:
1. An inhalator-breathing apparatus fitable inside the mouth of a human between cheek and teeth which apparatus comprises: elongated tube means having at least one upstream opening adapted to communicate the interior of said tube means with the atmosphere and at least one downstream opening adapted to communicate said interior of said tube means with the rear portion of said mouth, 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 to a point adjacent the molars; retainer means disposed integrally within said tube means, a prepared source of gas-like material suspension retained in said tube means by said retainer means so that inhaled air flowing through said tube means will contact at least in part a gas-like material suspension emanating from said prepared source of gas-like material suspension therby generating an air to gas mixture transferable to said rear portion of said mouth by way of said downstream opening; and sealing means adapted to fit at least in part between frontal teeth and lips being attached to the upstream portion of said tube means thereby to seal off the flow of air through said mouth except into said tube means through said upstream opening; said upstream opening and said downstream opening in combination with the cross sectional area of said interior of said tube means being of a size sufficient to allow a flow of air through said tube means approximate to the flow of air said human could achieve through normal nasal breathing.
