Portable smoke and fire protection device and methods relating to same

A device for protecting a user from smoke or fire, comprising:

• (a) a sealed dome-like cover defining a cover interior for receiving the user, a cover apex for receiving the user's head, a cover bottom edge distally opposite the cover apex, a cover front portion and a cover rear portion opposite the cover front portion;
• (b) an opening provided in the cover front portion, sufficiently sized such that emergency oxygen received through the opening forces any smoke present under the cover to be expelled by positive air pressure through the space below the cover bottom edge;
• (c) an integrated oxygen tubing having an elongate tubular structure whose proximal end is connected to the opening provided in the cover front portion, and whose distal end is provided with a distal opening to receive emergency oxygen that passes through the integrated oxygen tubing to the opening provided in the cover front portion;
• and
• (d) a closable lateral opening provided on the a side of the tubing such that when the lateral opening is open, air flows out of both the opening provided in the cover front portion and the closable lateral opening, and such that when the lateral opening is closed, oxygen flows only to the opening provided in the cover front portion, thereby enabling the selective sharing of an oxygen source by more than one user.
