Patent ID: 7927482

Claim:
A dental waste system for containing and removing substantially all contaminated dental waste including contaminates in suspension produced at a dental facility without discharge to a sewer, said dental waste system comprising: a first dental waste container generally fixedly installed within a dental facility, said first dental waste container being adapted to receive contaminated dental waste; a second dental waste container generally fixedly installed within the dental facility, said second dental waste container having a volumetric capacity greater than said first dental waste container; a vacuum conduit connected to said first dental waste container; a vacuum pump connected to said vacuum conduit to selectively generate a vacuum pressure within said first dental waste container; a suction conduit in fluid communication with said first dental waste container and operable in response to a vacuum pressure generated by said vacuum pump to transfer dental waste containing a contaminant from the mouth of a dental patient to said first dental waste container whereby substantially all contaminated dental waste is contained within said first dental waste container including contaminates in suspension; a waste removal conduit, said waste removal conduit being in fluid communication with said first dental waste container and said second dental waste container and adapted to transfer substantially all dental waste from said first dental waste container into said second dental waste container, said waste removal conduit including a check valve and a vacuum tube being connected to said check valve with said vacuum pump selectively generating a vacuum pressure within said vacuum tube, said check valve being responsive to deactivation of said vacuum pump to enable dental waste to flow from said first dental waste container to said second dental waste container when said vacuum pump ceases generating a vacuum pressure within said vacuum tube; and a discharge conduit, said discharge conduit being fluidly connected to said second dental waste container and enabling substantially all dental waste including contaminates in suspension to be removed from the dental facility without any fluids or dental waste being discharged to a sewer.
