Patent number: 10034731Abstract: An oral care appliance comprises an gas-liquid cleaning assembly which comprises a fluid pump assembly (46); a source of liquid (50); and a source of gas(12). The pump is in operative communication with the sources of liquid and gas to produce a series of gas-injected fluid pulses, directed to a nozzle assembly (80) from which the resulting pulses are directed to the teeth by a user. The individual pulses have a pulse width within the range of 0.001-0.5 seconds, a pulse height from 0.1-10 Newtons, a rise/fall time range of 0.5-250 ms, a repetition rate in the range of 2 Hz to 20 Hz. The gas/liquid mixture range from 40-95% volume to volume, gas to liquid. The appliance also includes a mechanical teeth cleaning assembly, in combination with the gas-liquid assembly.Type: GrantFiled: March 10, 2014Date of Patent: July 31, 2018Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Yu-Wen Chang, Gregory Russ Goddard

Patent number: 10022207Abstract: An oral irrigator including a handle through which fluid flows to a tip. Fluid flows to the tip during irrigate mode, and fluid flow may be interrupted by selecting a pause mode. The handle includes a mechanically controlled actuator for selecting the pause mode. The actuator may include a rack gear operably connected to a pinion gear formed on a valve spool inside the handle. The valve spool may include a ball that blocks fluid flow to the tip during pause mode but not during irrigate mode.Type: GrantFiled: November 26, 2014Date of Patent: July 17, 2018Assignee: Water Pik, Inc.Inventors: Kurt M. Taylor, Harold A. Luettgen, Jeremy James Johnson

Patent number: 10010389Abstract: An apparatus for providing 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. 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.Type: GrantFiled: November 18, 2014Date of Patent: July 3, 2018Assignee: Water Pik, Inc.Inventors: Brian Boyd, Brian R. Williams, Kurt M. Taylor

Patent number: 9999484Abstract: A device for use in retracting a gingiva from a human tooth by widening a gingival sulcus with a dental composition. The device comprises a cannula with a free end having an opening for dispensing the dental composition. The free end is shaped to be inserted with its front in the entry of the gingival sulcus, and to laterally displace the gingiva from the tooth as the cannula is moved in the gingival sulcus. The invention may help to achieve a reliable and cost effective gingival retraction treatment.Type: GrantFiled: October 10, 2014Date of Patent: June 19, 2018Assignee: 3M INNOVATIVE PROPERTIES COMPANYInventors: Helmut Pauser, RĂ¼diger Hampe, Christoph Schulte, Michael Knee, Andreas Maurer
