ABSTRACT:
A respiratory control comprising a mouthpiece of a shape and size for insertion in a person's mouth having a centrally located filtering cartridge and valve means to control the flow of air past the filtering material on inhale and out a separate exhale corridor on exhale so that the exhaled bacterial, virus or otherwise contaminated air is never mixed with the filtered and enhanced air and the filter is kept clean of contaminated air at all times. Thus, the inhalation of infectious substances of whatever type exhaled, or in the immediate area, are not recycled back into the body.
The filtering cartridge is a removable throwaway insert which can be simply plain, (dry), or medicated and can be made available as a sealed package purchasable separately from the mouthpiece and disposed after use.
In one embodiment the valve means is part of the filtering cartridge and in a second embodiment the valve means is part of the mouthpiece.
