Abstract

A dental massage device comprising a nozzle portion having one of its ends open and provided with gripping members adapted to fit over and grip a conventional faucet aerator in a sealing relationship therewith. Its other end is provided with an aperture which is connected by flexible conduit means to an ejector which is operably connected to the flexible conduit.

Claims5

Dependent claims

A dental massage device for coupling the cylindrical outflow end of a faucet to an elongated water ejector comprising:

(a) an adaptor means including
a generally cylindrical main body member provided with an axially formed chamber opening on a first end thereof and an axial bore extending from a second end thereof to open on said chamber, the peripheral surface of said main body member being provided with a plurality of longitudinally formed slots extending from said first end at least partially to said second end to thereby define a plurality of flexible gripping portions at said second end, each of said gripping portions being provided with a radially inwardly extending tooth means at its terminal end, and
sleeve means disposed over said main body member and slidable along the outer peripheral surface thereof, said sleeve means being operative to squeeze said gripping members radially inwardly when it is positioned around said gripping members, causing said tooth means to grip the outer surface of said cylindrical outflow end and said sleeve means allows said gripping members to expand radially outwardly when it is not positioned therearound, releasing the grip of said tooth means on said outer surface of said cylindrical outflow end;
(b) handle means including an elongated hollow member provided with a first axial bore extending from a first end towards a second end thereof and a second axial bore of a smaller diameter which extends from said second end towards said first end and which opens on said first axial bore, where an expanded portion of said water ejector can telescope into said first axial bore at said first end;
and
(c) flexible hose means including a tube having an external diameter less than said smaller diameter, the tube having a first end portion attached within the axial bore of said main body and having a second end portion disposed through said second bore and into said first bore, said flexible hose means further including a ferrule means inserted into said tube proximate said second end, said ferrule means having an outside diameter sufficient to expand the portion of the outer peripheral surface of said flexible hose which surrounds said ferrule to a diameter greater than said second diameter, thereby preventing the withdrawl of said tube from said handle means.
