Emergency vision apparatus with touch sensitive screen and closable hand opening

摘要

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.

1. An emergency vision apparatus, comprising:
a) an inflatable first enclosure, said first enclosure being made of airtight material enclosing an interior space of said first enclosure and having an expanded form when deployed and a deflated form when not in use; b) first and second clear members disposed at respective first and second ends of said first enclosure to enable a user to see through said first enclosure when expanded and observe a source of information at said second clear member at a distal end of said first enclosure while smoke or other particulate matter is in the environment; c) a touch sensitive screen visible through said first clear member; d) said first enclosure including an opening communicating with said interior space and the outside of said first enclosure, said opening being configured for insertion of a user's bare hand and arm to allow the user to enter said interior space and operate said touch sensitive screen with the user's bare hand while visible through said first clear member; e) a closure for closing said opening, said closure is operable to allow the user's bare hand to extend through said opening inwardly into said interior space and to seal said opening around the user's arm while disposed in the opening to reduce an amount of gas within said interior space from escaping through said opening; f) a first sheet partly covering said opening, leaving an uncovered portion, said first sheet including a first edge disposed over said opening; g) a second sheet disposed over said uncovered portion, said second sheet including a first portion overlapping said first sheet, said first portion including a second edge; and h) said first and second edges are oriented in substantially the same direction.
