  • Surface breathing device
    Patent number: 5845637
    Abstract: An ambient air breathing device for use in combination with a full face mask. Full face masks are intended to be sealed around periphery of the face of the wearer and, therefore, require that the wearer breath on tanked air even before such air would be necessary to sustain life. The breathing device of the invention allows the wearer to breathe ambient air thus conserving otherwise supplied air for use when needed.
