| Abstract: |
The specification sets forth a mouthpiece for use with a snorkel or regulator of the type used in diving and life support systems. The mouthpiece is attached to a snorkel or regulator by a conduit and terminates in a lip flange for seating within the upper and lower lips. Extending between the lip flange is an upper palate web that conforms to the palate area of a user's mouth. Within the palate web is an opening toward the frontal area for receipt of a user's front teeth. The mouthpiece incorporates a lower web that extends along the inner jaw region overlying the inner portion of a user's lower teeth. The lower web can be split in its conformation with a gap therebetween formed by two tabs that are rounded at their ends. The entire mouthpiece conforms and holds the snorkel or regulator in a user's mouth in a facile manner without the requirement of excessive biting and eliminates prior art lugs or bits.

1. A mouthpiece for a second stage breathing gas regulator comprising:
- conduit means adapted for connection to an outlet of a second stage regulator so that gas being regulated by said second stage regulator can pass through said conduit means as well as exhaust from a user's mouth through said conduit means;
- a mouthpiece portion extending from said conduit means said mouthpiece portion having a curved upper lip flange adapted generally for conforming to the interior region of a user's mouth between the upper teeth and the user's upper lips and a curved lower lip flange adapted generally for conforming to the interior region of a user's mouth between the user's lower teeth and the inner lower lips respectively;
- said upper lip flange and said lower lip flange being joined to each other in a region intermediate between them;
- each said upper flange and said lower flange including a frontal portion substantially coextensive with said conduit means and two opposed lateral portions extending from said frontal portion;
- an upper interior web joined to and extending from said region between said upper and lower lip flanges, and being anatomically shaped for contact with at least part of the inside surfaces of at least the frontal upper teeth of a user and for extension at least partly in contact with a user's palate;
- a lower web joined to and extending from the region between said upper and said lower lip flanges, said lower web being anatomically shaped for contact with at least a portion of the inside surfaces of the lower teeth of a user and for extension at least partly in contact with a user's interior lower jaw portion; and
- each said upper web and said lower web including a frontal portion substantially coextensive with said conduit means and two opposed lateral portions extending from said frontal portion.
