<p>This invention provides a device, and a method for skin cleaning using sonic energy coupled to the skin with a liquid filled cleaning chamber (10). Rather than immersing the skin in the chamber, the cleaning chamber has an opening therein which fits against the skin. A cleaning liquid such as water or a solution of water with cleaning agents, fill and circulates through the cleaning chamber. A sonic transducer (20) is vibrational coupled with liquid in the cleaning chamber to transfer sonic vibrations to clean the liquid therein. The opening in the cleaning chamber is preferably lined with a seal (21), such as a rubber elastomeric seal to keep the cleaning liquid in the chamber. Alternatively, the cleaning chamber can be made of a resilient material. The sonic transducer operates at a frequency between 200 Hz, and 1,000,000 Hz. In a preferred embodiment the frequency of the transducer is substantially resonant with the frequency of the liquid filled chamber.</p> |
