Image Number 3 for United States Patent #7241208.
A micro-abrasion device includes a base station, a handpiece configured to spray a powder onto skin, a flexible supply pipe configured to supply powder from the base station to the handpiece, a flexible return pipe configured to return powder from the handpiece to the base station, a first reservoir containing a powder to be supplied to the handpiece via the flexible supply pipe and a first reservoir endpiece initially closed by a puncturable seal, and a second reservoir configured to collect powder returning via the flexible return pipe. The first reservoir and the second reservoir are assembled together and mounted onto the base station during use. Once mounted, the seal is punctured. Preferably the first and second reservoirs are configured so that they cannot be interchangeably mounted on the base station. This prevents reuse of the collected used powder in the second reservoir.
