ABSTRACT:
An emergency escape device includes a transparent impervious flexible hood to be placed over a user's head sealingly affixed to an inflatable collar. An annular saddle-shaped reservoir contains a supply of pressurized oxygen gas and is concentrically positioned on the collar so that when the collar is inflated the weight of the reservoir seals the collar around the user's neck. A control mechanism is actuatable by the user for delivering the oxygen to simultaneously fill the hood and inflate the collar. A scrubber is located within the hood for cleansing carbon dioxide from the exhalations of the user to enable the hood gas to be rebreathed by the user. An ejector is connected to the oxygen supply line and is located adjacent the scrubber to create a venturi effect to cause the hood gas to pass through the scrubber and enable the hood gas to be recycled.
