Abstract
Abstract An apparatus to clean teeth. The apparatus has a reservoir for cleaning liquid and a pump to force cleaning liquid from the reservoir. There is an outlet from the reservoir formed with an attachment. A wand can be attached to the outlet. The wand has an inlet to communicate with the outlet. There is a wand outlet at the distal end of the wand. The wand outlet is dimensioned to ensure that a moderate pressure jet of liquid can be ejected from the outlet. The limb is shaped to allow the jet of liquid to be directed upwardly to the teeth being cleaned and against the gums. In a preferred embodiment, the wand has bifurcated limbs at its distal end and each limb has a wand outlet on an inner surface. The limbs can receive dental floss.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
137 words
Portable, lightweight, apparatus to clean teeth comprising: An intergral reservoir for cleaning liquid; means to force cleaning liquid from the reservoir; an outlet from the reservoir formed with attachment means; a wand to be attached to said outlet and having an inlet to communicate with said outlet and bifurcated limbs at its distal end, each said limb having a cruciform wand outlet on an inner surface dimensioned to ensure a moderate pressure jet of liquid from said outlet and being positioned in said limb to direct a jet of liquid at an angle of about 110° to 120° to the longitudinal axis of a tooth, away from the gum; and means adjacent to distal end each limb to attach dental floss, said means being positioned further from the distal end of said bifurcated limbs than said outlet.
Claim 2
Dependent Claim
137 words
Portable, lightweight, apparatus to clean teeth comprising: An intergral reservoir for cleaning liquid; means to force cleaning liquid from the reservoir; an outlet from the reservoir formed with attachment means; a wand to be attached to said outlet and having an inlet to communicate with said outlet and bifurcated limbs at its distal end, each said limb having a cruciform wand outlet on an inner surface dimensioned to ensure a moderate pressure jet of liquid from said outlet and being positioned in said limb to direct a jet of liquid at an angle of about 110° to 120° to the longitudinal axis of a tooth, away from the gum; and means adjacent to distal end each limb to attach dental floss, said means being positioned further from the distal end of said bifurcated limbs than said outlet.
Claim 3
Dependent Claim
20 words
Apparatus as claimed in claim 1 in which the means to force liquid from said reservoir comprises a hand-operated pump.
Claim 4
Dependent Claim
20 words
Apparatus as claimed in claim 1 in which the means to force liquid from said reservoir comprises an electric pump.
Claim 5
Dependent Claim
14 words
Apparatus as claimed in claim 3 that includes batteries to operate said electric pump.
Claim 6
Dependent Claim
14 words
Apparatus as claimed in claim 1 in which the wand includes a flexible portion.
Claim 7
Dependent Claim
50 words
Apparatus as claimed in claim 5 in which the wand comprises a separate flexible portion and an end portion, each attachable to each other, the end portion is semi-rigid and thus shapable by the user, the wand including a relatively rigid portion along its length to act as a handle.
Claim 8
Dependent Claim
34 words
Apparatus as claimed in claim 5 in which the wand outlets are formed of limbs, each having a length of about 3 to 4 mm and a width of about 0.5 to 0.75 mm.
Claim 9
Dependent Claim
32 words
Apparatus as claimed in claim 1 in which the means in said limbs to attach dental flees comprises a frame, that can be attached to and removed from between the bifurcated limbs.
Claim 10
Dependent Claim
55 words
Apparatus as claimed in claim 8 in which there is a recess in the base of said bifurcated limbs and recesses adjacent the outer ends of said limbs; the dental floss being formed on a frame having projections corresponding to said recesses to engage in the recesses in the bifurcated limbs to maintain its position.
Claim 11
Dependent Claim
40 words
Apparatus as claimed in claim 9 in which the frame includes a cross piece and in which the distance from the floss to said cross piece is pre-determined to control the depth of insertion of the floss between the teeth.
Claim 12
Dependent Claim
26 words
Apparatus as claimed in claim 9 in which there are slots along the interior surface of the limbs to receive the outer surfaces of the frame.
