Abstract
A disinfectant and flush system for a dental waste evacuator comprises a container filled with disinfectant and connected to the interior of a main flow tube of the evacuator, positioned between a disposable mouth piece and a suction source. A control valve is installed between a tubing leading from the disinfectant container and the main flow tube, which ensures that the disinfectant is admitted into the main flow tube during operation of the evacuator to flush the tube continually or intermittently.
