ABSTRACT:
A safety device integrated into a respiratory system that includes an oxygen mask having a cup-shaped rigid portion overlying a face mating portion to define a respiratory envelope that is adapted to sealingly engage over the mouth and nose of a user. An integrated control circuit includes an externally mounted connection block and a circuit looping through the respiratory envelope. A hands-free, mouth-activated switch is located within the cup-shaped rigid portion and is electrically coupled to the control circuit.
