<p>A dermabrasion apparatus operates by a flow of air and reducing substances conveyed to a patient through a handpiece. The apparatus includes an oval-shaped mixing bottle that has a first enclosed region for holding reducing substances. The mixing bottle includes a cap that has two tubes extending therefrom, for coupling to respective input and output legs of the handpiece. The mixing bottle also includes a second enclosed region for holding one of the two tubes that provides an air-tight coupling between the output leg of the handpiece and a collecting bottle. The mixing bottle is oval-shaped so that a user can readily manipulate the handpiece so as to move the handpiece coupled to the mixing bottle in a desired direction. This is especially useful for small handpieces that are hard to hold onto by themselves.</p> |
