Patent ID: 7438667

Claim:
An oral exercise device comprising: an upper lever having a proximal end and a distal end; a lower lever also having a proximal end and a distal end; a pivot between the upper lever and the lower lever, whereby the proximal ends of the upper lever and the lower lever move between a mutually separated position and a mutually adjacent position within a human mouth between a hard palate and a tongue, and whereby the distal ends of the upper lever and the lower lever likewise move between a mutually separated position and a mutually adjacent position in a manner opposite the proximal ends outside the human mouth; a tongue adaptor stably fastened to the lower lever, wherein the tongue adaptor conforms to a subject's tongue and causes the subject to actuate the oral exercise device with only the subject's tongue; a substantially convex hard palate adaptor stably fastened to the upper lever, wherein the hard palate adaptor can be custom-molded to the subject's hard palate; and at least one resistance element providing an isotonic resistance over a range of motion as the proximal ends move from the mutually separated position to the mutually adjacent position.
