ABSTRACT:
A man-portable light weight emergency oxygen supply system device for providing breathable oxygen for periods exceeding ten minutes. The device can be easily affixed to personnel for mobile use or mounted for stationary applications. A typical on-person system, weighing over three pounds, can supply pure oxygen for short periods of time, extending to the order of an hour for mixtures with ambient air to provide nominal sea-level oxygen concentrations. A catalyzed endothermic reaction is utilized to produce oxygen with no potential for harmful contaminants or danger of accidental initiation or fire/explosion hazard. Potential applications include use for emergency evacuations, such as hotel fires, aviation emergencies including de-pressurization and fires, and medical emergencies requiring oxygen administration prior to arrival of emergency medical equipment or ambulances.
