Device and system to improve asepsis in dental apparatus

Abstract

A method and system to improve asepsis during dental delivery includes a self-contained water delivery apparatus and a vacuum apparatus both of which provide disinfection of biohazards occurring during dental procedures. A UVC LED light emitting unit, with sanitary connections, may be releasably connected to the delivery and vacuum apparatus for improved maintenance and cleaning. A reservoir egress connector provides releasable engagement, fluid agitation, and unrestricted UV light transmission to improve water quality, reduce biofilm water contamination, reduce cross contamination, and reduce the potential spread of pathogens. The mounting system for the UVC LED light unit allows the apparatus to be used to decontaminate portable dental delivery units and vacuum units upon closure. A reflective interior of the cases improves irradiation of the enclosed system, reducing the risk and spread of pathogens.
