Abstract
The personal emergency breathing system includes a canister carrying a layered filtration unit, a mouthpiece, a hood, a cover and a lid at opposite ends. Upon removal of the cover, the mouthpiece and hood are deployed. By placing the mouthpiece in the user's mouth and donning the hood, the user may breathe filtered ambient air. At the opposite end of the canister is a demand valve having an oxygen supply line. Upon removal of the lid at the opposite end of the canister and coupling the supply line to an oxygen bottle, oxygen may be supplied the user, augmenting the supply of ambient filtered air. Thus, the user may clip the oxygen bottle along with the canister to his/her belt and escape from toxic gases and smoke-filled environments. The demand valve supplies oxygen to the user only upon inspiratory effort and closes upon exhalation, thereby extending a given supply of oxygen up to 150% as compared to a continuous supply of oxygen.
