<P>PROBLEM TO BE SOLVED: To provide a dental suction device which is remarkably compact and lightweight and is easily operated in comparison with conventional suction devices because, in suction mechanisms of the conventional dental suction devices, instruments are large and heavy for application using a large suction amount and there is a problem in suction and operation of liquid in an oral cavity. <P>SOLUTION: A ball valve is disposed in a valve housing part of a dental suction device body. A slide switch slid forward and backward with the finger to open/close a fluid passage of the ball valve is disposed on the surface of the ball valve housing part. An insert-fitting part for various suction tubes is disposed at the front end of the housing part, and a suction tube insert-fitting part whose deflection angle can be set is disposed at the rear end of the housing part. <P>COPYRIGHT: (C)2012,JPO&INPIT |
