ABSTRACT:
A filter system for coupling of dental handpiece is contemplated for use within a coupling system supplying air and water to a dental handpiece. The coupling system includes a swivel coupling including a series of axially and radially spaced annular couplings on an adapter, each of which supplies one of water, air supply, tool drive air supply or conveys exhaust air. The adapter permits use with standard handpieces. The filter consists of a small filter plate mounted under a cap at the proximal end of the coupling at the distal end of a chamber that receives water from the water source. Water from the water source is conveyed into the chamber, passes through the filter plate, and is conveyed through the coupling to the handpiece where it may be sprayed in the patient's mouth. A cap is threadably mounted on the coupling to close the chamber and the cap may be removed to either clean or replace the filter. The entire assembly may be autoclaved as a unit.
