  • Dental suction device
    Patent number: 7261560
    Abstract: A dental suction device includes a hollow tube having both flexibility and shape retainability. The tube has its both ends connected to a connector and is formed with suction holes. The connector can be connected to a vacuum source. A suction force produced by the vacuum source can thus be applied to the suction holes of the tube through a passage formed in the connector. The connector includes a valve for adjusting the degree of opening of the passage formed in the connector and thus the suction force applied to the suction holes. The valve includes a valve body mounted in the connector and a manual lever for controlling the valve body.
