  • Patent number: 8408483
    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.

  • Patent number: 8267331
    Abstract: The subject invention relates to a power sprayer that offers flexibility of movement because it can be battery operated and is designed to eliminate the need for cleaning its spray nozzle after being used. Paint colors can be changed quickly by simply changing the media cartridges that are adapted for simple attachment to the sprayer. These media cartridges also eliminate the inconvenience associated with refilling conventional power sprayers with a desired media. The present invention more specifically discloses a sprayer media cartridge system comprising: (a) a media container, (b) a self-cleaning nozzle, (c) a media shut-off means, (d) a primary media atomizing aperture in a configuration relative to the self-cleaning nozzle, (e) a movable media containment member within the media container, (f) a gas transfer interface, and (g) a power unit engagement means.
