Abstract: An apparatus for dental irrigation may be provided to project fluid onto the surfaces of, and the interproximal spaces between, a user's teeth and gum-line. The apparatus may comprise two hollow U-shaped manifolds having orifices located on their interior faces used as fluid jets. The manifolds may be connected, at a central point of reflection, by a rotating inlet joint which supplies the fluid flow. When placed in the user's mouth, the apparatus may be designed to receive the top and bottom sets of teeth in each corresponding U-shaped manifold, with orifices configured to provide fluid jets aligned towards the lingual and buccal side of the teeth. The orifices may be staggered to provide staggered fluid flow. A user's teeth may be cleaned with a controlled fluid flow by moving the apparatus in a sweeping motion between each set of rear molars.

Abstract: A self-sealed irrigation system for supplying a treatment fluid to a treatment site is disclosed. The system includes a flexible containment member that has a delivery channel which delivers treatment fluid to the treatment site, a sealing channel supplied with a suction force, and a recovery channel. The delivery channel delivers the treatment fluid to the treatment site. The recovery channel removes spent treatment fluid from the treatment site. The sealing channel hermetically seals the containment member to the body surface surrounding the area to be treated. The containment member is designed such that any spent treatment solution which should by-pass the recovery channel is drawn into the sealing channel thereby preventing any treatment fluid from leaking to the outside environment. The containment member is connected to a suction pump which circulates treatment fluid through the treatment site and a reservoir which supplies the treatment fluid to the system.

Abstract: The invention is directed to a jet nozzle (1) for a handle section of an oral irrigator. The jet nozzle (1) is provided with a nozzle head (2) having a discharge port (18) from which a liquid in the form of a single jet is dischargeable. The nozzle head (2) receives therein an impeller (6) rotary about an axis of rotation (4). The impeller (6) includes a bore (15) disposed at an angle (22) to the axis of rotation (4). The bore (15) is intended to direct the liquid to the discharge port (18). In operation, the impeller (6) executes a rotary motion about the axis of rotation (4). This creates a single jet exiting from the discharge port (18) and revolving on the surface of a cone. With this revolving single jet, a superior cleaning effect is accomplished in the cleansing and care of teeth and gums.
