Abstract
The invention is a dental irrigator for delivering irrigant solution from an irrigation solution reservoir to the site of a dental procedure. The irrigator comprises: a hollow dental tool modified by the addition of one or more curved blades either formed directly on the neck of the tool or on a sleeve attached coaxially to the neck, one or more inlets associated with each of the curved blades, a housing that provides a watertight volume surrounding the inlets while allowing the tool to be freely moved with respect to the housing, and a supply hose, which conducts the irrigant solution at relatively low pressure from the reservoir to the housing. When the dental tool is attached to the distal end of a dental hand-piece and the hand-piece is activated causing the tool to move, irrigation solution enters the hollow interior of the neck of the tool and, as a result of the forces created by the motion of the curved blades, is delivered at relatively high pressure to the site.
