US Patent 8057512 Combined teething ring and pacifier and associated method

A combined teething ring and pacifier may include a support member with a pacifier section and a teething ring section extending from the posterior and anterior sides thereof respectively. The teething ring may be removably coupled to the support member such that it may be removed therefrom while the pacifier remains situated inside the infant oral cavity. Multiple teething rings may be available to interchange with a single support member and pacifier. Further, the support member may include an automatic reciprocating mechanism for reciprocating the teething ring along an arcuate direction as the infant inhales air into the pacifier. The mechanism preferably includes an actuator that rotates inside an ambient-air diverting chamber as the infant breaths. With each rotation, the actuator contacts a trigger attached to the teething ring. The trigger may reciprocate along a linear path, thus urging the teething ring along the arcuate direction.
