Abstract:
The present invention provides an emergency vision apparatus, comprising a blower; an inflatable enclosure remote from the blower, the enclosure being made of airtight material and having an expanded form when deployed and a deflated form when not in use; first and second clear members disposed at respective first and second ends of the enclosure to enable a user to see through the enclosure when expanded and observe a source of information at a distal end of the enclosure while smoke or other particulate matter is in the environment; a switch operably associated with the blower to activate the blower and thereby inflate the enclosure when deployed; and an air passageway connecting the blower and the enclosure, the passageway being extendible from a shorter length to a longer length when the enclosure is deployed.
