THeORy OF OPeRATiOn
The Advanced Delivery System is a pneumatically controlled system that uses standard compressed air for operation of dental
tools and accessories and for pressurizing a closed water supply. The system uses air pressure from a foot control to operate
air driven tools and also to provide a signal to turn electric instruments on and off. This pneumatic control capability provides
flexibility in that additional instruments can be included on the system for operation from the same foot control as described
below:
Handpiece control and Operation
The system utilizes common dental industry type technology for selection and
activation of air driven drills and instruments via a five (5) position control block. The
block contains individual gasket diaphragms that are held in the closed position by
compressed air supplied by the handpiece holders. When a dental handpiece is
removed from its holder, the compressed air is relieved off the gasket diaphragms
for that particular instrument thereby allowing compressed air and water to flow to
the handpiece when the foot control is depressed. The flow rate of this compressed
air is controlled by individual stems on the top of the block and the flow of water by
individual needle valves with knobs located on the front and side of the unit.
Electric instruments such as the ultrasonic handpiece and electric motor are controlled via the same control block. However the
compressed air that flows from the block is routed to an air/electric switch that uses an air driven piston to close contacts when
activated to thereby send an electric signal for the ultrasonic and electric motor to operate. When the foot control is released,
these instruments will then turn off.
The System uses an air driven poppet style foot control valve that when depressed will send
compressed air to the control block to operate whichever handpiece is removed from its holder. The
foot control also features a toggle valve for selecting water to spray from the handpieces. When the
toggle is activated and the foot control is depressed, it will allow an air signal to travel through the
foot control tubing to open a water relay valve allowing water to flow to the selected handpiece.
When the foot control is released it will exhaust off the air to the water relay valve and allow it to
shut.
closed Water System
The Closed water system uses two one liter plastic bottles designed for holding pressure.
The bottles can be filled with clean tap or distilled water for the source of water supply to
the dental handpieces and air/water syringe. The system works by supplying regulated
compressed air which pressurizes the water within the bottle and forces it up through the
pick up tubing in the bottle.
