  • Removable dental work table with vacuum
    Patent number: 5529533
    Abstract: The present invention is a device which can be portable and easily attachable and removable from existing dental work station tables. The apparatus comprises a work platform which can be removably connected to the work station table. A suction tube at the work station can communicate with the surface of the work platform. The suction tube can easily be connected and disconnected from the work platform for use in treating the patient, such as providing mouth suction. The apparatus preferably is supported by a mounting means on the work table with the work platform preferably horizontal. Preferably the platform is supported by a support means through which it is attached by the mounting means to the table. The work platform thereby provides both support for the article being worked on and suction to remove debris.
