Abstract
Abstract A pair of cavities are provided in a housing for receiving hands and forearms, a plurality of nozzles within each of the cavities eject streams of fluids inwardly at predetermined rates and pressures in order to exert a net force on the inserted hands and forearms sufficient to support their weight within each cavity so that they do not touch the interior surface of the cavity and thereby remain uncontaminated after the washing procedure.
