Sa-li′va–pump.
（Dentistry.) A device to remove the saliva from the mouth during dental operations. The tongue and cheeks are kept from contact with the teeth of the lower jaw, and the saliva drawn off by an air-pump through a perforated tube into a receiver. The air-escape valve is between the receiver and the exhaust-bulb of the pump. In Fig. 4555, the rebent upper end of the pipe has a rose head to take up the saliva. A compressible bulb and two valves form the operative mechanism.
