| Abstract: |
A thin, flexible shield for the mouth to protect against transmission of STDs (Sexually Transmitted Diseases) during cunnilingus and oral-anal sex. A shield (32) is held over the mouth either alone or in a holder assembly (44) by mounting devices which retain the mask against the face of the user. The holder assembly (44) may consist of one or two rings (30U, 30L) interlocked with each other or with the shield to grip the shield.

- a substantially non-permeable, semi-flexible peripheral frame member defining a passageway therethrough, and dimensioned to continuously surround the lips of a user during movements of the mouth, said frame member further formed for positioning beneath the nasal cavities of said user, said frame member further formed to be substantially narrow and sufficiently rigid;
- a substantially non-permeable, relatively thin, pliable and distendable membrane mounted to said frame and extending across said passageway to provide a pliable barrier over said lips and said mouth, said membrane being substantially more flexible and pliable than said frame member a means for removably attaching said membrane to said frame;
- a pair of mounting devices coupled to opposite sides of said frame, each mounting device being formed for engaging a portion of said user's head for retaining said mask against said face underneath said nasal cavities.
