ABSTRACT:
An adaptor for a dental syringe handpiece has a central bore forming two chambers one of which receives a disposable syringe tip and the other selectively applied pressurized water and/or air from the handpiece. The adapter in one embodiment has a shoulder in the central bore acting as a stop for the tip to form the two chambers. In another embodiment, a tube attached to the adaptor in the adaptor bore serves as a stop for the tip. In another embodiment the tube has a sharp edge which engages the tip in the adaptor bore. The tip is urged against the edge by a gripping member and nut as the nut is tightened over the adaptor. The tip has several embodiments wherein a central passageway is surrounded by a plurality of outer passageways, the outer passages being arranged in arrays on different diameter circles. The outer passageways may be of different diameters and shapes. In a further embodiment, the tip is axially positioned in the adaptor bore at different positions to form an air-water mixing chamber of variable volume which sets the spray from a fine to coarse stream wherein the coarse stream is mainly large water droplets and the fine stream is a mist of fine water droplets and air. In a further embodiment, an anti-microbial agent is added to the plastic material forming the adaptor and tip to minimize microbes in the dispensed fluid.
