Patent number: 8241586Abstract: This ozone appliance for the professional dental office and other medical applications introduces dissolved ozone into dental and surgical operatory water lines. This dissolved ozone can not only disinfect water and water lines; it can also reduce gum bleeding, gingivitis, bad breath, teeth stains and oral bacteria. Additionally, it can aid in wound disinfection in surgery and attack microbial contamination of water from dental and surgical operatory water lines and attached hand pieces and dispensing devices by automatically killing waterborne germs and destroying biofilms where germs can hide and grow. It can, therefore, be used to disinfect water lines in dental operations and for other medical applications such as providing liquid containing ozone for cleaning and disinfecting skin prior to surgery (and tissue exposed during surgery). Further, a unit connected to operatory water lines can give an audible or other alarm if the water becomes unsafe.Type: GrantFiled: February 13, 2002Date of Patent: August 14, 2012Assignee: Alab, LLCInventors: William A.

Method and system for conducting vapor phase decontamination of sealable entities and their contents
Patent number: 8236240Abstract: The invention provides a method and system for conducting a continuous operation, flowing vapor phase decontamination in either an open loop or a closed loop. Using the method, a multi-component liquid decontaminant is vaporized and delivered into, through and out of a sealable enclosure by means of a carrier gas that is flowing into, through and out of said sealable enclosure. After leaving the enclosure, the vapor is captured in a cold-water bath and decomposed. The invention humidifies the carrier gas by passing it through a temperature controlled water bath to warm, or to cool, the carrier gas as necessary in order to bring the carrier gas to the desired temperature and humidity before it is combined with the vaporized sterilant and allowed to flow into the sealable enclosure. The concentration of the vapor sterilant and the percent saturation of the vapor sterilant are simultaneously controlled by controlling the rate at which the carrier gas flows and the rate at which the liquid sterilant is vaporized.Type: GrantFiled: January 23, 2007Date of Patent: August 7, 2012Inventors: James Arthur Childers, Robert Warren Childers -

Publication number: 20120164025Abstract: The presently disclosed subject matter provides a package and methods for disinfecting a wide variety of microbiologically contaminated products. Particularly, the disclosed package comprises a package to house the product to be disinfected and a disinfecting gas generator positioned within the interior of the package. The materials used to construct the package and/or the gas generator comprises an active agent that neutralizes the disinfecting gas from the interior of the package.

Patent number: 7964138Abstract: An on-demand portable chlorine dioxide generator has a reagent bound medium in a first enclosed volume; a complementary reagent solution in a second enclosed volume, and a structure for selecting between a first position where the complementary reagent solution is forced through the reagent bound medium and a second position where said complementary reagent solution remains isolated from the reagent bound ion exchange medium, where a ClO2 solution is generated only during periods when the structure for forcing is actuated. The ClO2 solution can be discharged for use as a portable sprayer that can be used to treat surfaces infected by anthrax or other biological contaminants. When the bound reagent is chlorite, the complementary reagent is an acid or an oxidant. When the bound reagent is an acid or an oxidant, the complementary reagent solution is a chlorite solution.Type: GrantFiled: November 29, 2006Date of Patent: June 21, 2011Assignee: University of Florida Research Foundation, Inc.Inventors: David E. Richardson, Daniel Denevan, Dwight C. Ramdon

Publication number: 20110124928Abstract: An apparatus for producing a gas using a raw material gas having high reactivity, in particular, a fluorinated hydrocarbon, or a vessel for supplying the gas, characterized in that the surface of a portion thereof contacting with the gas has an average roughness of 1 ?m or less in terms of a center line average roughness Ra. It is preferred that an oxide-based passivated film such as a film based on chromium oxide, aluminum oxide, yttrium oxide, magnesium oxide or the like is formed on the surface having a roughness controlled as above. The above apparatus and vessel can be suitably used for preventing the contamination of a raw material gas originated from a gas production apparatus or a vessel for supplying the gas.Type: ApplicationFiled: January 12, 2011Publication date: May 26, 2011Applicant: Zeon CorporationInventors: Tadahiro Ohmi, Yasuyuki Shirai, Takeyoshi Kato, Kimiaki Tanaka, Masahiro Nakamura, Katsutomo Tanaka

Patent number: 7931859Abstract: Systems and methods to reduce bioburden on at least a portion of a fluid transfer port include supplying a dose of radiation to the portion in optical communication with at least one source of radiation. In an illustrative example, a medical container, such as a vial or IV bag, receives a dose of ultraviolet (UV) energy substantially at a predetermined region of a fluid transfer site. In some examples, such a sanitization process may precede a fluid transfer operation in which a fluid is transferred into or out of the medical container by passing through the sanitized region. Such fluid transfers may be used in automated or semi-automated pharmaceutical processes, such as drug reconstitution. Various embodiments may further include one or more seal assemblies, each seal assembly having an aperture through which the radiation dose is supplied from the source to a controlled region on the fluid transfer port.Type: GrantFiled: February 22, 2008Date of Patent: April 26, 2011Assignee: Intelligent Hospital Systems Ltd.Inventors: Lance R.
