Oral respirator device and method for mask-free filtering of particulates from breathed air

摘要

An oral respirator device and method for mask-free filtering of particulates from breathed air. A surgical mask is removably disposed within a housing. The housing has an air chamber, a first air inlet, a second air inlet, and a means of securing the surgical mask filter. Operably attached to the housing is an oral interface (such as a surgical tube). In one embodiment, the oral interface has three openings, one of which is a mouthpiece while the other two openings, the ends of the tube, are connected to the air inlets of the housing. Environmental air enters the air chamber of the housing via the filter becoming filtered breathable air. The filtered breathable air enters the mouth of the user via the oral interface. In one embodiment, one-way valves are operatively connected to the oral interface.
