Publication number: 20230372569Abstract: Systems and methods in accordance with embodiments of the invention can operate to decontaminate an environment or surface. In a number of embodiments, an environment or surface is decontaminated by simultaneously exposing it to a combination of peracetic acid vapour and UV-C light. In some embodiments, peracetic acid is aerosolized, then vaporized, and then delivered to a target environment or surface in combination with UV-C to thereby disinfect the target. In various embodiments, the paracetic acid is aerosolized using either a mesh nebulizer or a pneumatic nebulizer.Type: ApplicationFiled: December 7, 2021Publication date: November 23, 2023Inventor: Vladimir Berentsveig

Patent number: 9448213Abstract: Methods for determining the amount of residual sterilant remaining on the surface of an object at the end of a disinfection process are described. One method of determining the amount of residual sterilant on a test piece after a sterilization regime in a sterilization space includes the steps of: placing a test piece having a predetermined surface area into the sterilization space; subjecting the test piece to the sterilization regime; collecting the residual sterilant from the test piece in a collector solution; and measuring the amount of residual sterilant in the collector solution.Type: GrantFiled: May 12, 2014Date of Patent: September 20, 2016Assignee: Saban Ventures Pty LimitedInventors: Michael Potas, Vladimir Berentsveig

Patent number: 9358315Abstract: A method of sterilizing an object comprising the steps of i) placing an article to be sterilized in a sterilization chamber; ii) providing a sterilizing mist (for example hydrogen peroxide solution) to the sterilization chamber, thereby to contact said article for a first duration; iii) providing a gas flow to said chamber for a second duration, thereby to displace, where present, said sterilizing mist and to remove, where present, condensed mist from said article; wherein the total reduction in micro organisms over a time period encompassing the first duration and the second duration is less than log 6; and wherein steps ii) and iii) are repeated at least once to achieve a predetermined sterilization parameter such as a predetermined sum total of contact time between the sterilizing mist and the article, a predetermined sum total of sterilizing mist provided to the sterilization chamber or a predetermined level of sterilization.Type: GrantFiled: June 30, 2009Date of Patent: June 7, 2016Assignee: SABAN VENTURES PTY LIMITEDInventors: Vladimir Berentsveig, Ron Weinberger, Michael Potas

Patent number: 9333275Abstract: A manifold which introduces sterilant aerosol to a sterilization chamber for the disinfection of an article. The manifold defines the terminal portion of a fluid pathway from an aerosol generator to the sterilization chamber and comprises at least one chamber inlet port for introducing aerosol into the sterilizing chamber. The manifold is configured to provide directional aerosol flow tangential to the surface of the article, which is preferably of a known configuration and maintained in a predetermined position with respect to the manifold, such that it does not receive a direct flow of aerosol from the manifold. Preferably, the manifold is U-shaped, or bifurcate and defines a plane and with a chamber inlet ports are directed away from that plane. The chamber inlet ports are preferably paired so they create a circular motion of aerosol that moves around the article. Also sterilization apparatus including the manifold.Type: GrantFiled: January 8, 2014Date of Patent: May 10, 2016Assignee: SABAN VENTURES PTY LIMITEDInventor: Vladimir Berentsveig

Patent number: 9226495Abstract: Aerosols comprising droplets dispersed in a carrier gas, wherein at least some of the droplets contain an antagonist effective to inactivate a biocide are provided. The droplets may contain the biocide and the antagonist that reacts with the biocide to render it harmless. The biocide is used for disinfection or sterilization, and the nature and concentration of the antagonist is selected, or means are provided, to ensure that the time required for the antagonist to render the biocide ineffective is longer than the time required for the biocide to be effective for a desired level of disinfection or sterilization. Methods of manufacture of aerosols are also provided.Type: GrantFiled: May 21, 2010Date of Patent: January 5, 2016Assignee: SABAN VENTURES PTY LIMITEDInventors: Vladimir Berentsveig, Ron Weinberger

Patent number: 9192164Abstract: A method for disinfecting or sterilizing an article comprising enclosing the article or article part inside a container having a wall of which at least a part is a semipermeable fabric or membrane and introducing an amount of vaporizable biocide, preferably hydrogen peroxide in water, to the interior of said container in solution, vapor, liquid or preferably nebulant form. The semipermeable fabric or membrane is selected to allow the biocide to pass from inside to outside of the container as a vapor at atmospheric pressure and to provide a barrier against entry of micro-organisms. The biocide is allowed to exit the container through said membrane while at or above atmospheric pressure, a fluid eg air is directed to flow adjacent the outside of the membrane to expedite vapor removal from the interior side. The article is exposed to the biocide for a time sufficient to disinfect or sterilize the article.Type: GrantFiled: October 21, 2013Date of Patent: November 24, 2015Assignee: Saban Ventures Pty LTDInventors: Vladimir Berentsveig, Ron Weinberger
