Method and apparatus for disinfecting fluid medium removed from the oral cavity of a human being

Claim 3

The method according to claim 1 wherein said treating composition includes additional active substances selected from the group consisting of anti-corrosion inhibitors and deodorants.

Claim 4

The method according to claim 1 wherein said treating composition comprises a solution.

Claim 5

The method according to claim 1 wherein the treatment composition is contained in a porous carrier and is adapted to continuously release a certain quantity of the microbiocidal substance embedded therein over a given time period.

Claim 6

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.

Claim 7

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.

Claim 8

The apparatus according to claim 5 wherein said treatment composition comprises said microbiocidal substance and a solidifying gel, said microbiocidal substance being embedded therein.

Claim 9

The apparatus according to claim 5 wherein said treatment composition is granular.

Claim 10

The apparatus according to claim 5 including a porous carrier, said treatment composition being arranged on said porous carrier.

Claim 11

The apparatus according to claim 8 wherein said porous carrier is provided for insertion around the periphery of and arranged to be detachably secured to said tube.

Claim 12

The apparatus according to claim 8 wherein said carrier comprises an absorbent sleeve impregnated with the treatment composition.
