ABSTRACT:
The apparatus is adapted for maintaining air/gas operated dental drills, mechanical scalers or other tools by blowing air/gas through the handpiece to purge it from excess substances in order to enhance the life of the toll and meet the requirements of health and safety regulations. The apparatus has an absorbant filter sleeve that will serve to surround the instruments to be purged and an internal filter. It uses a rigidly anchored coupling that can be replaced, as desired. It also uses pneumatic tubing and shuttle valves to direct the air/gas flow along with switches that control the power and operation of the apparatus. A pressure gauge is mounted on the housing to allow the user to observe the pounds per square inch pressure being used in the purging operation. A timer controlling the amount of time the instruments are being purged is also incorporated. A number of ports are used to allow connection air, water and fiber optic lines to the apparatus and exhaust ports are also available.
