A device for blowing powder onto teeth, the device consisting of a handpiece in the form of a housing connected to a compressed air source and having a discharge nozzle member which can be inserted in a patient\s mouth and can be directed towards the patient\s teeth. The housing has a powder reservoir with a bottom supply duct. An apertured shuttle bar is reciprocably slidably mounted beneath said duct and has a metering hole registrable with said supply duct and then, by longitudinally moving the bar, with a discharge conduit arranged to receive compressed air from the source so as to discharge a metered amount of powder in said hole into the nozzle member for delivery to the patient\s teeth.

대표청구항 ▼

A therapeutic air/powder suspension spraying device for dental treatments comprising a handpiece in the form of a housing, powder reservoir means to contain a dental treatment powder in dry form, said reservoir means being mounted on said housing and having a bottom discharge orifice, a shuttle bar slidably mounted in a close-fit manner in said housing subjacent said orifice, said shuttle bar having a metering aperture registrable with said orifice to receive a metered volume of dry powder, means biasing said shuttle bar in a first position, means to reciprocate said shuttle bar between said first position and a second position, means in said housing substantially sealing the metering aperture against leakage during the filling thereof and the reciprocatory movement of the shuttle bar, means to deliver pressurized air comprising an air delivery conduit means in said housing opening at one side of said shuttle bar, discharge conduit means in said housing opening at the opposite side of said shuttle bar in alignment with said air delivery conduit means, said air delivery and discharge conduit means being offset from the reservoir bottom discharge orifice but aligned with the reciprocatory path of movement of said metering aperture, a compressed air source connected to said air delivery conduit means, and powder-guiding nozzle means connected to said discharge conduit means to direct powder to the teeth, to restrict the size of the spray area and to control the ejection velocity of the air/powder suspension.
