Abstract: An oral irrigator including a reservoir, a handle, and a tip connected to the handle and in fluid communication with the reservoir. The oral irrigator also includes a base unit including an operating assembly configured to selectively provide a first fluid from the reservoir to the tip. The operating may include, an some examples, a motor and a pump. The oral irrigator further includes a fluid pressure trigger connected to the handle and including a second fluid. Based on a pressure of the second fluid, the fluid pressure trigger closes an electrical contact to the operating assembly causing the operating assembly to selectively vary at least one characteristic of the first fluid flow from the reservoir to the tip.

Abstract: A sonic toothbrush system including an electric motor, a brush shaft, a drive assembly, a fluid conduit connected to a pressurized, pulsed water source, and a water jet nozzle positioned on the brush head and connected to the fluid conduit. The electric motor includes a drive shaft. When the electric motor is caused to operate, the drive shaft continuously rotates until the motor is caused to stop. The drive assembly is coupled between the drive shaft and brush shaft. The drive assembly is configured to convert the rotation of the drive shaft into sonic oscillation of a toothbrush supported on an end of the brush shaft. The drive assembly further forms part of the fluid conduit to deliver a pulsed water stream to the jet nozzle.

Abstract: A powered irrigator for use in rinsing nasal cavities including a main body having a handle and fluid reservoir detachably coupled to one another, an outlet nozzle extending from a top end of the handle, a pump mechanism operably coupled to a power source, and a switch operably coupled to the power source for turning the pump mechanism on and off, and when the switch turns on the pump mechanism, fluid flows from the fluid reservoir into a first fluid coupling between the reservoir and the pump mechanism and into a second fluid coupling between the pump mechanism to the outlet nozzle. The reservoir includes a generally centrically body defining a cavity and at least two tabs connected to the cylindrical body and extending inwards therefrom. The at least two tabs operably connect the reservoir to the handle portion to releasably secure the reservoir to the handle portion.
