Publication number: 20210369899Abstract: Disclosed is a method of sterilizing an article by sequentially exposing the article under vacuum first to a gaseous conditioning agent for forming radicals and then to a sterilant. The preferred conditioning agent is hydrogen peroxide and the preferred sterilant is ozone. The chamber is initially evacuated to a first vacuum pressure and then sealed for the remainder of the sterilization process and during all sterilant injection cycles, without removal of any component of the sterilization atmosphere, which means without any measures to reduce the water vapor content. Keeping the chamber sealed and maintaining the conditioning agent and the radicals generated thereby in the chamber for the sterilization with sterilant results in a synergistic increase in the sterilization efficiency and allows for the use of much lower sterilant amounts and sterilization cycle times than would be expected from using the conditioning agent and the sterilant in combination.Type: ApplicationFiled: August 16, 2021Publication date: December 2, 2021Applicant: TSO3 Inc.Inventors: Sylvie Dufresne, Cynthia Martel, Helene Leblond, Nancy Dassie, Karine Martel

Patent number: 9101679Abstract: A method of sterilizing an article by sequentially exposing the article to hydrogen peroxide and ozone is disclosed. The article is exposed under vacuum first to an evaporated aqueous solution of hydrogen peroxide and subsequently to an ozone containing gas. The exposure is carried out without reducing the water vapor content of the sterilization atmosphere, the water vapor content being derived from the aqueous solvent of the hydrogen peroxide solution and from the decomposition of the hydrogen peroxide into water and oxygen. The complete sterilization process is carried out while the chamber remains sealed and without removal of any component of the sterilization atmosphere. For this purpose, the chamber is initially evacuated to a first vacuum pressure sufficient to cause evaporation of the aqueous hydrogen peroxide at the temperature of the chamber atmosphere. The chamber is then sealed for the remainder of the sterilization process and during all sterilant injection cycles.Type: GrantFiled: September 29, 2010Date of Patent: August 11, 2015Assignee: TS03 Inc.Inventors: Simon Robitaille, Sylvie Dufresne, Jean-Martin Vallieres, Cynthia Martel, Helene Leblond, Nancy Dassie, Marie-Christine Gagne, Karine Martel, Claudia Bedard, Bruno Tremblay
