  • Patent number: 4848366
    Abstract: A mask system and device for an individual including a front portion defining a surface which is generally C-shaped and preferably forms bights or curved surfaces in both the horizontal and vertical cross section. The surface extends from and conforms to a position below the eyes to an area below the chin. The mask also includes sides integrally formed with the front portion and positioned adjacent the cheeks or jaw. The surface, in part, defines a cavity between the sides adjacent the individual's nose and mouth. An exhaust device is affixed to a defined channel formed on one lateral side. The opposite lateral side forms an intake port. Securing straps are provided to retain the mask portion adjacent the face. The exhaust device is provided at the free end of a tube which communicates with the side channel to create a continuous air flow across the cavity and to exhaust stale exhaled air.
