Apparatus for dental irrigation

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 substantially planar wall of the first manifold and a second set of one or more outlets laid out on a second substantially planar 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 being shaped to accommodate a tooth and configured to glide across a plurality of teeth in a user's dental arch;
• a second manifold having a third set of one or more outlets laid out on a first substantially planar wall of the second manifold and a fourth set of one or more outlets laid out on a second substantially planar wall of the second manifold, and at least one second 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 second manifold being shaped to accommodate a tooth and configured to glide across a plurality of teeth in the user's dental arch;
• and
• a rotating inlet joint comprising an inlet channel to receive fluid and a rotating joint to channel the fluid in substantially opposing directions into the first manifold through the at least one first inlet, and into the second manifold through the at least one second inlet,
• wherein the rotating inlet joint, the first manifold, and the second manifold are positioned so as to approximately align with an approximately central vertical axis of common symmetry, and reflect about an approximately central horizontal axis of symmetry, such that the first manifold and the second manifold are positioned at opposite sides of the rotating inlet joint and are oriented in opposite directions, and
• wherein the first manifold and the second manifold rotate about the axis of common symmetry;
• wherein the rotating inlet joint is configured to rotate about the axis of common symmetry, and wherein the angle of rotation of the rotating inlet joint about the axis of common symmetry impacts a property of the fluid flow to a user's teeth and associated gums.

An apparatus for dental irrigation, the apparatus comprising:

• a first manifold including a first shell having an inner portion and an outer portion, the first shell having a first set of one or more outlets laid out on a first substantially planar wall and a second set of one or more outlets laid out on a second substantially planar wall, wherein the first wall approximately faces the second wall,
• wherein at least one of the first wall and the second wall is capable of contacting a user's tooth;
• wherein at least a portion of the first manifold further is shaped to accommodate a tooth and configured to glide across a plurality of teeth in a user's dental arch;
• a rotating inlet joint configured to enable a flow of a fluid into the first manifold from an inlet channel at any angle of rotation about an axis of rotation;
• wherein the inner portion and the outer portion of the first shell cooperate to direct the fluid flow substantially perpendicularly to the fluid flow exiting the inlet channel, and then substantially parallel to the fluid flow exiting the inlet channel, then substantially perpendicularly again.
