  • Patent number: 9743999
    Abstract: A dental prophylaxis and air appliance having a pressurized air source, a hand piece, and a manually actuated slurry container containing a mixture of dry or wetted abrasive and non-abrasive components. The compressed air is delivered to the hand piece by a line that combines the compressed air with the components and discharges the post-mixed water slurry of abrasive or non-abrasive components. The hand piece is configured to include a series of valves adapted to define one or more stages for containing components and encourage mixing thereof during operation.

  • Publication number: 20040202980
    Abstract: A dental prophylaxis and air appliance for in-home use having a pressurized air source, a pneumatic or mechanical switching device to turn on and off the air source, a hand piece, and a pressurized reservoir for a mixture of dry or wetted abrasive and non-abrasive components. The compressed air is delivered to the hand piece by a line that meters out and discharges the post-mixed water slurry of abrasive or non-abrasive components.

  • Patent number: 5393228
    Abstract: A dental prophylaxis and water conservation device for in-home use. The device includes a tank coupled to the household water supply line and adapted to receive water which causes air contained within the tank to be pressurized. The water and air from within the tank are connected by lines to a handpiece which discharges both mediums simultaneously. Water leaving the tank passes through a container having an abrasive material which is picked up by the water and also discharged. The tank is further coupled to a plumbing fixture, such as a shower head. This enables the tank to be used as a water conservation device by allowing cold water to be purged from a hot water line into the tank, and subsequently used to provide water to the plumbing fixture. To recycle the purged water, the present invention entrains the water from within the tank as water from the supply line is being provided to the plumbing fixture.
