Patent ID: 8215958

Claim:
A dental irrigator for delivering irrigation solution from an irrigation solution reservoir to the site of a dental procedure, said irrigator comprising: a) a hollow dental tool comprising a neck; b) one or more inlets created through the wall of said neck; c) a housing adapted to provide a volume of irrigation solution around said inlets while allowing said tool to be freely movable with respect to said housing; d) a supply hose, which conducts the irrigation solution at relatively low pressure from the reservoir to said housing; and e) a curved blade located in the hollow interior of one of (i) the neck of the hollow dental tool and (ii) a sleeve attached coaxially to said neck, the curved blade shaped such that when the hollow dental tool is attached to a dental hand-piece and said hand-piece is activated causing the hollow dental tool to move in a reciprocating linear motion with respect to the housing, said irrigation solution flows into the hollow interior of said neck of said tool and as a result of forces created by the motion of the curved blade is delivered at relatively high pressure to the site, and said curved blade extends curvedly inwards into a hollow internal space of said neck.
