  • Patent number: 12109084
    Abstract: An oral irrigator having an irrigator tip, the tip including a handle portion, a tip portion, a channel in fluid communication with the tether and arranged within the handle portion and the tip portion, and an actuator located on or within the handle portion, the actuator arranged to at least partially altar a flow of a fluid through the channel. The oral irrigator further includes a housing, the housing having a reservoir in fluid communication with a pump sub-assembly, a sensor arranged to measure a first pressure or first electrical load within the pump sub-assembly, and a control unit arranged to control an operational current provided to the pump sub-assembly where operation of the actuator produces a second pressure or electrical load measured by the sensor and the control unit is arranged to alter the operational current of the motor in response to the change.

  • Patent number: 10642948
    Abstract: The appliance includes a jet source of fluid, and a nozzle assembly through which the fluid is directed and then out for application to the teeth. A flow interrupter assembly is mounted within the nozzle assembly, such that the interrupter assembly is responsive to the fluid flow to produce momentary successive interruptions of the fluid flow by the action of the interrupter assembly moving from an original position to a flow interrupting position and then returning to its original position as the flow decreases and then is interrupted, due to the fluid flow itself, resulting in a cyclical perturbation in the fluid flow from the nozzle, by flow action alone.

  • Patent number: 10172688
    Abstract: According to various implementations, a dental cleaning device includes a steam conduit and a cooling fluid conduit. The steam conduit has a distal tip with an opening defined therein that allows steam to be applied intraorally close to a dental implant to flush away bacteria that has colonized on or adjacent the dental implant. The cooling fluid conduit has a distal tip with an opening defined therein that allows a cooling fluid to be applied intraorally close to the dental implant following the application of the steam to cool the tissue and prevent overheating of the tissue and bone adjacent the dental implant. For example, the cooling fluid may be applied intermittently with the steam, or the cooling fluid may be applied continuously while the steam is applied intermittently, according to various implementations.

  • Patent number: 8876528
    Abstract: A dental appliance having a passive arrangement for drawing liquid from a reservoir (22, 33, 54) in the appliance by action of a stream of gas, which can be provided by a source of compressed gas (31, 34) or other system. The liquid mixes with the gas, resulting in liquid droplets which are directed through an orifice (18, 42, 68) at the end of a nozzle portion (12, 39, 66) of the appliance.

  • Patent number: 6406447
    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.

  • Patent number: 6245032
    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.

  • Patent number: 6139319
    Abstract: The invention is directed to a jet nozzle (1) for a handpiece of an oral irrigator, which has a nozzle head (2) in which a feed line (4) runs. The feed line (4) opens into an outlet orifice (5) from which a liquid can emerge in the form of a single jet. A constriction (6) is provided in the feed line (4). The constriction (6) acts to produce a large number of microfine gas bubbles. The microfine gas bubbles are better suited to penetrate deep into subcrestal pockets in order to kill anaerobic bacteria which have settled there by the supply of oxygen, hence treating and curing inflammations of the gums.
