Abstract
Microdermabrasion and suction massage apparatus are included in a single unit and alternatively connectable through a mode switch to a source of vacuum. The microdermabrasion section of the unit includes a crystal pick up station operating with a venturi effect to draw crystals through a hole into an air stream. The size of the hole is variable to control crystal density. A bleed valve is provided to control crystal velocity without controlling crystal density, while a bypass valve is provided to control crystal density without controlling crystal velocity. In an associated method, a microdermabrasion procedure is performed on the skin of a patient at an operative site. The mode switch is operated to activate the suction massage apparatus within the unit. This step is followed by performing a suction massage procedure at the operative site in order to promote healing of the abraded skin. The unit can be back-flushed by connecting various portions of the unit to a pressurized output of the source of vacuum.
