Abstract

A portable dental apparatus. A main housing includes a plurality of wheels mounted therebeneath. A control panel on the main housing includes a variety of controls for operating a plurality of dental tools removably and suspendedly mounted to a holder in turn movably mounted to the main housing. A storage cavity formed in the housing allows storage of the holder and tools when the portable dental apparatus is in a transport state. The tools are connected by a plurality of lines to a plurality of drive and power components located in the interior of the main housing. A lid hingedly mounted atop the control panel may be opened revealing the controls for the tools. An X-ray display screen and amalgamator are provided respectively on the lid and control panel.

A modular vacuum unit with a built in cooling fan and thermo protector is also provided. Additionally, the portable dentist apparatus includes an improved pressurized air and water distribution manifold and an improved waste water storage receptacle. Furthermore, the waste water receptacle has means provided to automatically shut off the vacuum motor when the receptacle is full or when the receptacle is placed improperly in the unit. The receptacle also has means provided to baffle fluids flowing into the receptacle such that fluids will not back flow into the vacuum motor.

Claims
