ABSTRACT:
A face mask includes a cup-shaped body for enclosing an external respiratory organ, such as the nose, of a patient. Flow of a respirable gas into the body and exhaust of expired gas from the body are unidirectional controlled by respiration check valves. The mask is molded of an elastomer which is permeated with an odorous medium to emit a selected scent. The mask is colored to impart a visual perception corresponding to the scent. A plurality of detachably securable and interchangeable accessory devices adapt the mask for use with selected prior art scavenging devices.
