Abstract:
The device presented herein is a Disposable Adjustable Flow Prophy Angle (DAFPA) attachment with an integral feed mechanism to expel a predetermined quantity of abrasive medium into a polish cup. During use, the high speed rotation of the drive shaft driving the angled attachment will propel the abrasive medium into the flow channel, via a propellant screw. A sealing ring is incorporated to protect against any backflow of the abrasive medium. A significant feature of the device is the ability to continually adjust the flow of abrasive medium deposited into the polish cup by a calibrated flow adjustment knob, providing the advantage of selecting a predetermined flow rate, to accommodate the needs of the health care professional. The current procedure is more time consuming and less sanitary. In the proposed system the abrasive medium is fed continuously or on demand from an internal reservoir.
