| Abstract: |
The integrated breathing system of the present invention incorporates a mask covering the nose and mouth, an intake having two side hoses and a central inlet tube, and a window mount. The two side hoses attach to the opposite sides of the mask and surround the user's head for stability, connecting in the rear to the central tube. The central tube extends oppositely to a connection with the window mount for communication with air on the other side of the window. The window mount can be a foam block, a clip or an adjustable block, and a fan or other air conditioning means can be incorporated for providing a positive air flow to the mask. The system is an inexpensive and simply constructed alternative to the expensive breathing systems used in work places.

I claim:
1. A portable system for providing air to a user in contaminated areas comprising a tight-fitting, washable, filterless air mask covering a user's nose and mouth, and having right and left sides, an adjustable head strap attached to the mask for holding the mask firmly over a user's nose and mouth, right and left air supply inlet and exhaust tubes connected to the sides of the mask and extending around right and left sides of a user's head and check valves in the mask for controlling flow from and to the inlet and exhaust tubes and the mask respectively and for preventing contact of the valves with contaminated air, and for preventing airborne materials outside the mask from clogging the valves, the right and left inlet and exhaust side tubes connecting behind a user's head to a main inlet tube and a coaxial exhaust tube, the main inlet and exhaust tubes being flexible and having distal ends connected to a releasable window mount.
