A skin treatment device having a treatment window for treating skin through the treatment window and a user guide to deliver a tactile feedback signal during movement in stepwise increments of the treatment window along the skin.

Skin treatment device with means for providing a tactile feedback signal

The mouthpiece appliance includes an assembly for receiving teeth () which includes a plurality of cleansing portions, typically two opposing side portions () and an intermediate center portion (). The brushing portions include bristle sections which are adapted to clean teeth. The appliance includes at least one DC motor assembly () with an output shaft with an eccentric mass of crankshaft (). The appliance further includes a mechanical motor cover comprising a plurality of arm members which are arranged to connect the DC motor assembly to the cleansing portions of the appliance so that as the unbalanced weight on the output shaft rotates, movement of the cleansing portions, toward and away from the teeth or along the surfaces of the teeth occurs, producing cleansing of the teeth.

Mouthpiece for cleaning teeth with a mechanical drive train

A mouthpiece appliance includes an assembly for receiving teeth which includes cleansing portions, such as two opposing side portions and an intermediate center portion. The brushing portions include bristle sections which are adapted to clean teeth. The appliance also includes at least one DC motor assembly with an output shaft with an eccentric mass of crankshaft. The appliance further includes a mechanical motor cover including arm members which are arranged to connect the DC motor assembly to the cleansing portions of the appliance so that as the unbalanced weight on the output shaft rotates, movement of the cleansing portions, toward and away from the teeth or along the surfaces of the teeth occurs, producing cleansing of the teeth.

The mouthpiece includes a mouthpiece carrier member () having upper and lower sections which are adapted to receive the upper and lower teeth of a user. The mouthpiece carrier member has several embodiments which include side members and an intermediate member or members connecting the two side members to define the two sections. A bristle field () is mounted on the mouthpiece carrier member for contact with the surfaces of the teeth. The mouthpiece carrier member is moved in such a manner to produce a bristle action which has a significant axial component, resulting in the bristle tufts moving toward the teeth, contacting the teeth and moving away from the teeth, producing cleaning action on the teeth.

System for axial bristle motion in a teeth cleaning mouthpiece

The mouthpiece () includes receiving portions for receiving teeth from the upper and lower jaws. The teeth receiving portions includes two side portions () which are joined by flexible members () to a front portion (). The two side portions move laterally relative to the front portion by the flexible members to accommodate a variety of dental arch configurations.
