Abstract
The present invention provides a saliva evacuator system for removing saliva, and optionally debris, from the mouth of a dental patient. The saliva evacuator system includes a vacuum pump, a flexible tubing connected at one end to the vacuum pump, and a tip assembly at the other end of the tubing, the tip assembly carrying a vacuum on/off valve. The on/off valve is positioned so that the on/off valve remains outside of the patient's mouth when the tip assembly is inserted into the patient's mouth. The on/off valve is a single-piece body push valve that is transversely movable within a hollow body of the tip assembly and is retained on the hollow by opposite ends of the on/off valve. One end of the on/off valve preferably clips onto the hollow body. The tip assembly can include a saliva ejector tip, a high-volume evacuator tip or a surgical high-volume evacuator tip.
