    Abstract: The present disclosure is directed to mechanisms for oral irrigator fluid channels which provide back flow prevention. The oral irrigator comprises: an irrigator tip; a tether having a first end and a second end, a third channel arranged between the first end and the second end, where the first end of the tether is in fluid communication with the second channel; a reservoir containing a fluid, the reservoir in fluid communication with a pump, the pump in fluid communication with the third channel and the second end of the tether; and an arrowhead check valve comprising a resilient element and an elastic head element, the arrowhead check valve arranged within the first channel, the second channel, or the third channel. The irrigator tip comprises: a nozzle comprising a first channel; and a handle comprising a second channel in fluid communication with the first channel.

    Abstract: A skin treatment device especially for use for treating skin in terms of cleaning, exfoliating and/or massaging the skin. The device comprising a housing and a skin treatment head releasably attached to the housing. The skin treatment head being rotatable around an axis element associated with the housing, wherein the housing encloses an actuator configured to rotate the skin treatment head, wherein the skin treatment head comprises one or more brushes associated with a support element), wherein the device further comprises a first thermally conductive element configured at a shortest distance to the one or more brushes selected from the range of 0-40 mm, and wherein the device further comprises a thermoelectric element configured to heat in a first mode the first thermally conductive element to provide a hot surface.

    Abstract: A valve assembly (10) including first and second housing parts (22, 24). The first and second housing parts are secured to each other such that respective channels in each are aligned to define inlet and outlet fluid pathways (25, 35) through the valve assembly. A leaf valve insert (38) is arranged between the first and second housing parts, and includes a plurality of leaves (40). First and second leaves are respectively aligned with the inlet and outlet fluid pathways. The first leaf (40a) is configured to permit fluid flow in the inlet fluid pathway in a first direction while impeding fluid flow in a second direction. The second leaf (40b) is configured to permit fluid flow in the outlet fluid pathway in the second direction while impeding fluid flow in the first direction. The first direction is from the first housing part toward the second, and the second direction is from the second housing part toward the first.

    Abstract: A mouthpiece device for fitting inside the mouth of a user and carrying an array of flexible, protruding cleaning elements for performing an oral cleaning function at a plurality of locations around the mouth at the same time. The surface(s) of the mouthpiece device which carry the cleaning elements also carry spacer elements protruding from said surface is a same general direction as the cleaning elements. The spacer elements enforce a minimum spacing between the surface(s) of the mouthpiece device body and the oral surfaces (e.g. dental surfaces) when the mouthpiece is received in the user's mouth.

    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.
