Abstract: An embodiment of a brush head assembly for a powered toothbrush includes a housing, a first brush head supported by the housing, and a second brush head supported by the housing. In addition, the brush head assembly includes a driveshaft positioned in the housing and coupled to the first brush head and the second brush head, the driveshaft having a longitudinal axis. A rotation of the driveshaft about a longitudinal axis is configured to pivot the first brush head and translate the second brush head relative to the housing.

Abstract: A toothbrush provides a head with bristles, a neck and a handle. An eccentrically rotational weight is engaged for rotation with a motor. The motor and weight are disposed within the handle. The handle, neck and head each have a different intensity of vibration. The toothbrush houses an electrical circuit, which includes a processor and at least two LEDs (light emitting diodes) at least one of which illuminates the neck and optionally also the head and the ends of the bristles attached to the head. At least two of the LEDs in the circuit are capable of emitting different colored light with respect to each other. The at least two LEDs are switched on for a predetermined time in a predetermined sequence under the control of the processor.

Abstract: A medication delivery pen having a vial retainer with a side opening have flexible snap wings that spread to receive and retain a standard or threaded vial within the vial retainer. The vial retainer also includes an improved means of attaching the vial retainer to a pen injector body, using a cam and cam follower design together with a ratcheting mechanism to prevent removal of the vial from the medication delivery pen. Alternatively, a release mechanism could be used so that the vial may be removed from the medication delivery pen. In addition, the vial retainer includes an opening for receiving the vial defined by a pair of flexible snap wings.
