ABSTRACT:
A portable dental apparatus for treating patients or animals in remote locations comprises a dental drill driven by an air turbine; a pressurized air supply for driving the turbine and for pressurizing a water supply; and connections and valving for operating the drill and cooling it with a stream of water from the water supply and for squirting air or water from the air and water supplies with a squirt nozzle. Tile pressurized air supply derives its air from manual pumping, preferably with a double-action pump and a check valve to minimize fluctuations in the air flow rate. Such a pump either forms part of the air supply or is used to fill an inflatable container. The air supply may consist of the inflatable container alone, or of one or two double-action pumps, or of the container and one pump. The water supply comprises a can having a capped opening at or near its top for filling with water when needed, a tubule extending from its inside near its base to above its top, and a threaded opening in or near its base into which is screwed an adapter that can be either plugged or used to enlarge the capacity of the water supply. The apparatus also comprises quick disconnect and connect tubing between the air supply, valving, water supply, drill, and squirting nozzle to facilitate its assembly and disassembly.
