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.

Claims

1. In an inhalation mask for administering a respiratory gas to an individual, the improvement for appealing to the senses and for alleviating the anxiety of the individual prior to placement of the mask over an external respiratory organ of the individual, wherein said mask is molded from a mixture comprising:

a) non-porous thermoplastic base material; and

b) odorizing and colorizing means combined with said base material before molding, said odorizing and colorizing means emitting a selected scent and imparting to said mask a selected color commonly associated with said scent.

2. The improvement of claim 1, wherein said odorizing and colorizing means comprises an ingredient constituting approximately 3% to 6% by weight of said mixture.

3. The improvements of claim 1, wherein said selected scent simulates the odor of a selected food product.

4. The improvements of claim 3, wherein said selected color corresponds to the color of said selected food product.

5. The improvements of claim 1, wherein said thermoplastic material is an elastomer.
