Abstract

An apparatus may include one or more manifolds, each including a shell having an inner portion and an outer portion. Each shell may have a first set of outlets in a first wall and a second set of outlets in a second wall that approximately faces the first wall. Each manifold is shaped to accommodate a tooth. A rotating inlet joint, having an inlet channel and a rotating joint, may enable fluid flow into each manifold from the inlet channel at any angle relative to an axis of rotation defined by the rotating joint. In each manifold, the first set of outlets and the second set of outlets are oriented towards a tooth and/or gums associated with the tooth. The inner portion and the outer portion of each shell cooperate to direct fluid flow substantially horizontal to, and then substantially perpendicular to, the fluid flow exiting the inlet channel.

a rotating inlet joint comprising an inlet channel and a rotating joint, the rotating inlet joint being configured to enable a flow of a fluid into the first manifold and the second manifold from the inlet channel at any angle of rotation about an axis of rotation defined by the rotating joint;

wherein the first set of one or more outlets and the second set of one or more outlets are oriented towards a tooth accommodated by the first manifold and gums associated with the tooth;

wherein the third set of one or more outlets and the fourth set of one or more outlets are oriented towards a tooth accommodated by the second manifold and gums associated with the tooth.

2 . The apparatus of claim 1 , wherein at least a portion of the inlet channel of the rotating inlet joint protrudes from the rotating inlet joint to form an angle relative to the axis of rotation.

3 . The apparatus of claim 2 , wherein the angle of rotation impacts a property of the fluid flow to a user's teeth and associated gums;

wherein the impacted property comprises a rate of fluid flow, and wherein the impact is a reduction of the rate.

4 . The apparatus of claim 1 , wherein the first manifold and the second manifold have a fixed orientation relative to one another.

5 . The apparatus of claim 1 , wherein the rotating inlet joint is disposed between the first manifold and the second manifold.

6 . The apparatus of claim 5 , wherein the rotating inlet joint channels the fluid in substantially opposing directions into:

the first manifold towards the first set of one or more outlets and the second set of one or more outlets, such that the fluid is channeled to be expelled from the first set of one or more outlets and the second set of one or more outlets, and

the second manifold towards the third set of one or more outlets and the fourth set of one or more outlets, such that the fluid is channeled to be expelled from the third set of one or more outlets and the fourth set of one or more outlets.

7 . An apparatus for dental irrigation, the apparatus comprising:

a first manifold having a first set of one or more outlets laid out on a first wall of the first manifold and a second set of one or more outlets laid out on a second wall of the first manifold, and at least one first inlet, wherein at least one of the first wall and the second wall is capable of contacting a user's tooth, and wherein at least a portion of the first manifold is shaped to accommodate a tooth and configured to glide across the user's dental arch;

and
