  • Publication number: 20130189153
    Abstract: The instant invention provides methods and apparatus for disinfecting a space, e.g., a hospital room, using chlorine dioxide. One aspect of the invention provides an apparatus for disinfecting a space. The apparatus includes: a chlorine dioxide gas generator; a sensor adapted and configured to measure the relative pressure inside the space and outside the space; and a computer operatively connected to the sensor and the chlorine dioxide generator, the computer adapted and configured to control the chlorine dioxide generator to operate only when the space is under negative pressure as compared to outside the space. Another aspect of the invention provides a method of disinfecting a space. The method includes: setting an apparatus as described herein in the space; and allowing the apparatus to determine if the space is under negative pressure. If the space is under negative pressure, the apparatus generates chlorine dioxide gas to disinfect the space.

  • Patent number: 8476073
    Abstract: An automatic analyzing apparatus can properly determine a quality of an analysis supporting liquid, after being supplied to the automatic analyzing apparatus, which supports an analysis performed in the automatic analyzing apparatus and can properly maintain an accuracy of the analysis. The analysis supporting liquid which supports an analysis of a specimen is dispensed into a reaction vessel by using a specimen dispensing unit which dispenses the specimen, a reagent dispensing unit which dispenses a reagent, a cleaning unit which cleans the reaction vessel, or a diluted solution dispensing unit which dispenses a diluted solution. An optical measurement is performed with respect to a liquid including the dispensed analysis supporting liquid in the reaction vessel. Analysis data of the analysis supporting liquid is generated by using the measured result. The quality of the analysis supporting liquid is determined by comparing the generated analysis data with reference data.

  • Patent number: 8236240
    Abstract: 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.

In a first tier procedure, the air (in a structure or a predefined area) is continuously automatically screened at a plurality of different predefined locations by air sensors distributed in the area to be monitored. Each air sensor is configured to detect a potentially harmful substance that is carried by the air proximate the predefined location, to determine if a potentially harmful substance might be present, but need not identify a specific harmful substance. When a potentially harmful agent is identified by an air sensor in the first tier screening, a sample of the potential threat is collected, and a second tier procedure is initiated. The second tier procedure uses a manual test, such as a nucleic acid amplification and detection assay to detect any of a plurality of different specific threats in the sample.

  • Patent number: 8163234
    Abstract: The invention relates to a method for characterizing the bioindicators in sterilization processes using an autoclave and the like, in which a bioindicator is kept in the same conditions as the sterilization chamber (2) and extracted after a predetermined time interval. For this purpose the chamber (2) has, passing through it, a tube (5) on the ends of which valves (8-9, 10-11) are mounted, said valves allowing the insertion, from above, of a bioindicator sample and its extraction from below, when required, without a significant loss of sterilizing agent. Alternatively, the duct (5) may also be arranged outside the sterilization chamber (2) and kept in communication therewith by a bypass connection.

  • Patent number: 8153057
    Abstract: Disclosed is a method of controlling a real-time oxidation-reduction potential in a hot water system to inhibit corrosion in the hot water system. The method includes defining one or more operational protective zones in the hot water system. One or more of the operational protective zones includes an oxidation-reduction potential probe that is operable to measure a real-time oxidation-reduction potential in the hot water system at operating temperature and pressure. The probe transmits the measured real-time potential to the controller, which assesses and interprets the transmitted potential to determine whether it conforms to an oxidation-reduction potential setting. If the measured potential does not conform the oxidation-reduction potential setting, the controller is operable to feed one or more active chemical species into the hot water system.

  • Patent number: 8133434
    Abstract: In an exemplary embodiment, the present invention includes at least one reservoir with a delivery mechanism in communication therewith. The delivery mechanism draws an air treatment material from the reservoir and provides the air treatment material in response to a decreased level of active air treatment material or the detection of a malodor. Additionally, the delivery mechanism includes a control system and a detection system. The control system activates the detection system at a timed interval or in response to a change in one or more ambient conditions (e.g., motion, temperature, light, humidity, etc.). Once activated, the detection system samples the environment for either the level of active air treatment material or the quality of the environment.

  • Patent number: 8128869
    Abstract: An air sanitization system including a reactive oxygen species generator, a variable speed fan, a pathogen sensor and a controller. The reactive oxygen species generator generates reactive oxygen species from an oxygen-containing gas and discharges the reactive oxygen species to a conditioned space. The variable speed fan directs the oxygen-containing gas to the reactive oxygen species generator at a controlled speed. The pathogen sensor senses a level of airborne pathogens in the conditioned space and generates a signal indicative of the level of pathogens sensed. The controller receives the signal from the pathogen sensor and varies the speed of the variable speed fan in response to the signal to decrease a speed of the variable speed fan in response to an increase in the level of airborne pathogens sensed by the pathogen sensor.
