Abstract
An oral irrigator delivers a flow rate as a series of pulses, each pulse having an amplitude which increases progressively over at least the majority of the time duration of the pulse. Each pulse is intended for the cleaning of a single interdental space.
Claims19
An oral irrigator comprising:
- an output nozzle;
- a flow system for delivering a pressurized flow of liquid to the output nozzle for ejection from the output nozzle;
- and
- a controller for controlling a flow rate of the pressurized flow ejected from the output nozzle, the controller being adapted to deliver a flow rate which varies over time as a series of pulses, each pulse having a flow rate amplitude which increases progressively over at least a majority of a time duration of the pulse, and a time gap, being provided between the pulses, wherein:
- each pulse is for oral irrigation of a single respective interdental space;
- and each pulse comprises a series of incremental step increases in flow rate amplitude.

A method of providing oral irrigation, the method comprising:
- delivering a pressurized flow of liquid to an output nozzle for ejection from the output nozzle;
- and
- waiting for a time gap to move from interdental space to interdental space;
- and
- controlling a flow rate of the pressurized flow ejected from the output nozzle to deliver a flow rate which varies over time as a series of pulses, each pulse having an amplitude which increases progressively over at least a majority of a time duration of the pulse and a time gap being provided between the pulses, wherein:
- each pulse is for oral irrigation of a single respective interdental space;
- and each pulse comprises a series of incremental step increases in flow rate amplitude.
