Claims10
A method for continuously disinfecting a fluid medium, removed from the infectious area defined by the oral cavity of a human being comprising the steps of withdrawing said fluid medium as a flowing aerosol in a path from said infectious area under suction directly past a treatment zone, locating a treatment composition containing at least a microbiocidal substance within said treatment zone, said treatment composition being arranged about the periphery of said flow path of said aerosol in communication with said flowing aerosol without impeding the withdrawal of said fluid medium under suction or modifying the flow of aerosol, said suction acting to cause withdrawal of said microbiocidal substance from said composition and subsequent contact of said microbiocidal substance with said aerosol.
Apparatus for continuously removing and disinfecting the infectious fluid medium from an infectious area defined by the oral cavity of a human being, comprising an axially open flow through tube, connection means at one end of said tube connected to means for insertion into and contact with the infectious area for the removal of said infectious fluid medium therefrom, means at the other end of said tube for connection to a source of suction, and a source of suction for removing said fluid medium in the form of a flowing aerosol, said tube being perforated along a section between its ends, said perforated section being surrounded by an enclosed housing secured at its ends to said tube, a treatment composition containing at least a microbiocidal substance arranged within said housing about the outer peripheral surface of said tube free of the flow path of said aerosol, said composition to be subjected to a suction to release said microbiocidal substance through said perforations in contact with the flowing aerosol without impeding the application of suction to said infectious area or modifying the flow of aerosol.
