Abstract
Official abstract text for this publication.
An oral care appliance, comprising: a fluid flow pump assembly ( 46 ); a source of liquid ( 50 ); and a source of gas ( 12 ). The pump assembly is in operative communication with the sources of fluid and gas to produce a jet pattern of gas-injected fluid slugs, directed to a nozzle assembly ( 80 ) from which the resulting slugs are directed to the teeth. The individual fluid slugs in the jet flow have a volume in the range of 0.05-0.5 ml per orifice, a diameter in the range of 0.1-2 mm and a repetition rate within the range of 2 Hz to 20 Hz.
First claim
Opening claim text (preview).
What is claimed is: 1 . An oral care appliance, comprising: a fluid flow pump assembly; a source of liquid; a source of gas; and a microcontroller, wherein the fluid flow pump assembly is in operative communication with the sources of fluid and gas to produce a jet pattern of gas-injected fluid slugs, directed to at least one orifice of a nozzle exit assembly from which the jet pattern of gas-injected fluid slugs are directed to a user's teeth, and wherein the microcontroller is programmed to control an operation of the fluid flow pump assembly to produce individual gas-injected slugs effective against biofilm on teeth in the jet pattern that have a volume in a range of 0.05-0.5 ml per orifice of the nozzle exit assembly, a diameter in a range of 0.1-2 mm and a repetition rate within a range of 2 Hz to 20 Hz. 2 . The appliance of claim 1 , wherein the gas-injected fluid slugs comprise a gas-to-liquid mixture that ranges from 40-95% by volume, gas to liquid. 3 . The appliance of claim 1 , wherein the orifice of nozzle exit assembly comprises a fan angle that ranges from 0-10°. 4 . The appliance of claim 1 , wherein the nozzle exit assembly includes more than one orifice.
