EMERGENCY VISION APPARATUS WITH 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. The first enclosure includes a closable opening configured for insertion of a user's hand to allow the user to operate a touch sensitive screen or hardware disposed in front of the first clear member; and a sealable closure for closing the opening and sealing the opening around the user's hand.
