Abstract:
An emergency vision apparatus comprises an inflatable first enclosure, the first enclosure being made of airtight material and having an expanded form when deployed and a deflated form when not in use; and first and second clear members disposed at respective first and second ends of the first enclosure to enable a user to see through the first enclosure when expanded and observe a source of information at a distal end of the first enclosure while smoke or other particulate matter is in the environment. A touch sensitive screen is viewable through the first clear member. The first enclosure includes a closable opening configured for insertion of a user's hand to allow the user to operate the touch sensitive screen viewable through the first clear member; and a sealable closure for closing the opening and sealing the opening around the user's hand.
