  • Patent number: 10849726
    Abstract: The interproximal toothbrush includes an appliance body and neck with a nozzle member having a nozzle tip shaped to fit into interproximal teeth spaces. Bursts of air or air/liquid mixture are generated, exiting through the nozzle tip. A helix member or, alternatively, a spring, is supported within a channel in the nozzle member. The helix member is free to rotate as air or the air/liquid mixture is moved through the channel. A set of bristles is attached to a forward end of the helix member, so that it rotates with the helix member. Alternatively, a set of bristles is attached to the distal end of the spring so that successive bursts of air or the air/liquid mixture produce an in-and-out movement of the set of bristles toward and away from the teeth.

  • 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.
