referring to the drawings , a device formed in accordance with the present invention for practice of the present method is generally indicated at 10 in fig1 and 2 . the device incorporates an elongated stem 12 having a hand grip 14 formed at one end and a mouthpiece 16 affixed to the other end . mouthpiece 16 performs the function imparting vibrations generated by the device 10 , through a vibrator 20 ( fig3 ) supported in the handle 14 , into the teeth and thus the jawbone of a user and may take any of a variety of forms . in the preferred form , illustrated in fig1 , the mouthpiece 16 constitutes a substantially rigid elongated member , curved in the same manner as a typical dental arch . its upper and lower surfaces are formed with grooves 22 and 24 , respectively , which are adapted to engage these teeth . either one may be brought into contact with one set of teeth , or the user may bite on the device 16 so the dental arch is resting in the grooves 22 or 24 . the surfaces of the grooves 22 and 24 which contact the teeth are preferably aligned with a resilient material 26 to allow firm contact between the mouthpiece and the teeth without harming the teeth . the stem 12 is affixed at one end of the mouthpiece 16 so that vibrations induced into the stem cause similar vibrations of the mouthpiece . the handle member , formed at the other end of the stem 12 , incorporates an electrically powered vibratory mechanism 20 which may be of any conventional design , such as an electromagnet contacting an armature as in a conventional vibrator . the stem 12 is affixed to the vibratory mechanism 20 so that the motions of the vibratory mechanism are induced into the stem . the unit is preferably powered by a battery 30 through a switch mechanism 32 . the switch 32 may be accessed by the user through the handle . it may be placed in an on or off position , or in a position in which the vibratory mechanism 20 undergoes a cyclical vibration which may vary in frequency , intensity , or both . the handle 14 may incorporate dials 34 and 36 , which control rheostats 38 and 40 , connected to the vibratory mechanism so as to adjust the vibratory frequency and / or intensity . the user may vary these controls until an intensity and a frequency which achieves maximum relief of the pressure in the eustachian tubes is noted . as illustrated in fig2 , the user holds the device by the handle 14 with the mouthpiece in the oral cavity and adjusts the control so as to induce vibrations into the eustachian tubes or sinus cavities through the jawbone . the battery 30 is preferably rechargeable and is recharged between uses by supporting the handle 14 in a recharging stand 42 .
blocked fluid passages in the head are cleared by applying vibratory forces through the jawbone using a handheld appliance supporting a battery powered vibratory mechanism at one end of a handle and a mouthpiece at the other end .
