Abstract: An irrigator handle to be used with a water jet apparatus for cleaning gums and teeth includes a visual indicator to let a user know when a tip has been properly attached to the handle. The handle in some embodiments also includes an audible indicator to let the user know when the tip has been properly attached. The handle has a pause button attached to plunger to restrict water flow when the pause button is depressed.

Abstract: A pump for an oral irrigator includes a pump chassis, an eccentric end plate movably connected to the pump chassis, a first alignment shaft connected to the pump chassis, a second alignment shaft connected to the eccentric end plate, a first gear rotating around a longitudinal axis of the first alignment shaft, and a second gear engaging the first gear and rotating around a longitudinal axis of the second alignment shaft. By selectively moving the eccentric end plate relative to the pump chassis selectively moves the second gear relative to the first gear.

Abstract: A dental water jet apparatus for adjusting a pressurized water stream from a pump to a tip moves pressurized water from a reservoir to a tip in fluid communication with the pump. A flow control knob may be turned to selectively adjust the water pressure supplied by the tip between a minimum and a maximum value. When the flow control knob is turned in a first direction, the volume of fluid directed towards the tip decreases and the volume of fluid returned to an inlet of the pump increases. Fluid may flow from the reservoir and ultimately into the tip to provide oral irrigation and/or cleaning of the teeth, gums, and tongue.

Abstract: A dental water jet provides a pressurized water stream for cleaning gums and teeth. The embodiment includes a base unit defining a cavity. The cavity contains a pump, which may move pressurized water from a reservoir to a tip in fluid communication with the pump. A flow control knob may be turned to selectively adjust the water pressure supplied by the tip between a minimum and a maximum value. The reservoir may be removed from the base unit so that it may be filled with the fluid. The reservoir may support a container for storing tips or other items. Fluid may flow from the reservoir and ultimately into the tip to provide oral irrigation and/or cleaning of the teeth, gums, and tongue.

Abstract: An apparatus for providing a pressurized water stream for cleaning gums and teeth includes a base unit defining a cavity. The cavity contains a pump, which may move pressurized water from a reservoir to a tip in fluid communication with the pump. The pump may be secured within the cavity by at least one vibration reduction mount. Fluid may flow from the reservoir and ultimately into the tip to provide oral irrigation and/or cleaning of the teeth, gums, and tongue. The base may include a plurality of footings that elevate the base unit above a surface supporting the base unit. Also, the base may include a basin for receiving a reservoir. The basin may include a reservoir valve initially biased to a closed position and operationally attached to the reservoir, and a tube projection connected to the base unit and opening the valve when the reservoir is received within the basin. The basin and the reservoir are configured to guide the reservoir valve adjacent to the tube projection.

Abstract: Various embodiments of an end-of faucet filter assembly connectable with a faucet on a standard sink and having a plurality of outlets corresponding with selectable modes of operation are disclosed herein. One mode of operation provides unfiltered, aerated water dispenses from the filter assembly. A second mode of operation provides a pulsing jet spray, while a third mode of operation provides filtered water. One embodiment of the present invention also includes a connection assembly between the end-of-faucet filter and the faucet that utilizes a water-tight radial seal that allows the end-of-faucet filter to swing or rotate back and forth relative to the faucet without impairing the integrity of the seal. Other embodiments of the present invention also include a filter cartridge assembly configured to provide a user with an easy method of removing and installing the cartridge.

Abstract: Electrochemical apparatus and methods that support periodic, non-steady state, or discontinuous operation without suffering degradation of materials or loss of efficiency. The invention provides a means for positioning one or more electrodes into contact with electrolyte and means for retracting the one or more electrodes out of contact with the electrolyte. The means for positioning and means for retracting may be the same device or different devices. The means for positioning and means for retracting may be designed to provide automatic, passive, or fail-safe retraction of the electrode upon a given shutdown condition, such as a voltage of less than one Volt being applied between the first and second electrodes, expiration of a time period, an ozone concentration greater than a setpoint ozone concentration, contact pressure of less than 5 psig, and combinations thereof.

Abstract: A oral irrigator tip for an oral irrigator. The oral irrigator tip may include a shaft portion with a base, an apex, and a transitional portion linking the base to the apex. The shaft portion may be straight or angled. The shaft portion may be hollow from the base to the apex to define a fluid passage, thus permitting fluid to flow along the shaft portion. A retaining feature may be formed on the shaft portion to facilitate retention of the oral irrigator tip by an oral irrigator. A connector may join a nozzle to the shaft portion. Attached to the connector may be a bristle element, which may include multiple individual bristles glued or otherwise affixed to the connector. The bristles may be arranged in a circular pattern; water may flow around the individual bristles or through the center of the bristles.
