Abstract
Abstract A method and apparatus to kill pathogens with ozone and singlet oxygen. Includes steps of providing a reaction chamber, establishing an elevated electrical force field in the reaction chamber and moving a gas containing normal oxygen (O 2 ) through the chamber to permit ionization and consequent reaction within the gas which converts the oxygen (O 2 ) into constituents of ozone (O 3 ) and singlet oxygen (O 1 ). Next moves gas containing constituents into contact with pathogens to kill pathogens. Invention is applied to sterilize medical instruments and containers, and when applied to human skin surfaces, for treatment of pathogenic infestations.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
239 words
A method for killing pathogens contained within an electrically conductive liquid, with ozone (O 3 ) and singlet oxygen (O 1 ) comprising the steps of: (a) providing an annular chamber defined by (1) a cylindrical body of said electrically conductive liquid forming a first electrical conductor surface, (2) a cylindrical insulated tube confining said liquid, (3) said insulated tube forming a dielectric medium, and (4) a cylindrical metal housing enclosing said tube and forming a second electrical conductor surface; (b) establishing an elevated electrical force field in said annular chamber between said first conductor surface and said second conductor surface; (c) moving a gas containing normally occurring oxygen (O 2 ) into, through, and out of, said chamber at a moving rate suitably slow to permit ionization within said gas as caused while said gas is within said force field and thereby to transform said normally occurring oxygen (O 2 ) into the constituents of ozone (O 3 ) and singlet oxygen (O 1 ); and, (d) mixing said gas while containing said constituents immediately with said liquid containing pathogens in a venturi for the purpose of allowing said constituents to react with and to kill said pathogens, wherein said electrically conductive liquid is pumped through said tube and said venturi, and said gas is moved out of said chamber and mixed with said liquid by a vacuum created in said venturi by the pumping of said liquid.
Claim 2
Independent Claim
