The present invention relates to a method and device for sterilizing parisons made of a thermoplastic material that are intended for producing blow-molded containers. During the sterilizing process a sterilizing agent is introduced into an interior of the parison by an applicator. At least one gas is supplied to the applicator via at least one supply element, at least sections of which are arranged in a horizontal direction next to a transport path of the applicator. The supply element comprises at least one outlet opening facing towards the applicator. At least one pressure-applying element is arranged between the applicator and the supply element and is resiliently clamped between the applicator and the supply element.

A method for degrading organic fractions in cooling circuits in industrial plants, in particular plants in the metallurgical industry, including the following steps: adding bacteria to the cooling circuit, wherein the bacteria are suitable for degrading the organic fractions in the cooling circuit, and disinfecting the aerosol generated in a cooling tower of the cooling circuit. A cooling circuit for an industrial plant is also disclosed.

A class 5 chemical indicator color may be imaged such that a color of the indicator may be determined and compared to a color-value threshold indicative of an efficacious sterilization procedure. Color changes of the indicator during a sterilization procedure are typically not uniform. As such, colors on the indicator may be averaged and then compared to the color-value threshold to determine if the procedure has been efficacious or if additional exposure to a sterilant may be desired. Color values and color-value thresholds may be based on, e.g., the L*a*b* color model or a grayscale color model.

The compact devices with built-in power can be constructed for producing disinfectants that can impart hygiene and sterilization to the device users. The disinfectants may include ozone (O.sub.3), hydrogen peroxide (H.sub.2O.sub.2), peroxone (H.sub.2O.sub.3), singlet oxygen (O), hydroxy radical (.OH) and hydroperoxyl radical (HO.sub.2.). In the electrolysis, the anode generates O.sub.2 and O.sub.3, whereas the cathode products, namely, either hydrogen gas (H.sub.2) or H.sub.2O.sub.2, is dependent on the cathode materials utilized. When SS304 is used as the cathode, H.sub.2 will be generated. On the other hand, H.sub.2O.sub.2 is formed on using cobalt oxide plated on carbon nanofilm coated Ti (Co.sub.3O.sub.4-CNF/Ti) as cathode. On using the latter, O.sub.3 & H.sub.2O.sub.2 can be electrocatalytically cogenerated. When H.sub.2O.sub.2 mixes with O.sub.3, H.sub.2O.sub.3 will be formed, so are .OH and HO.sub.2.. O.sub.3 and H.sub.2O.sub.2 can not only contribute O.sub.2 to help human beings' breathing, they can impart human beings good health as well.

The present invention relates to methods and devices for providing microbial control and/or disinfection/remediation of an environment. The methods generally comprise: generating a Purified Hydrogen Peroxide Gas (PHPG) that is substantially free of, e.g., hydration, ozone, plasma species, and/or organic species; and directing the gas comprising primarily PHPG into the environment such that the PHPG acts to provide microbial control and/or disinfection/remediation in the environment, preferably both on surfaces and in the air.

A decontamination system for a lumen device is depicted. The decontamination system, in some embodiments, includes a lumen device container, a pump, and a sealed container with decontamination fluid. The lumen device container defines a lumen device receiving area. The pump is configured to reduce pressure within the lumen device receiving area. The sealed container is configured to release the decontamination fluid into the lumen device receiving area responsive to a pressure drop applied to the sealed container.

The invention relates to a disinfection method to be used for cleaning. The invention is characterized in that hydrogen peroxide (H.sub.2O.sub.2) is drained/transferred from one or more tanks (16) by a liquid pressure created by one or more pumps or gravity, through one or more draining pipes (6) to one or more draining devices (5), which draining device (5) drains hydrogen peroxide to one or more onto one or more evaporation top surfaces (4ea) of an evaporation member (4e) of a warming/heating device (4), the evaporation top surface (4ea) is at an evaporation angle (4ej) of 1 to 30 degrees in relation to the horizontal plane so that the end on the draining device (5) side draining end (4c) is higher than a gas discharge end (4d) at the opposite end of the draining device (5) of the warming/heating device (4), whereby hydrogen peroxide spreads by gravity on the evaporation

Systems and methods for reducing pathogens near an implant are discussed. In some cases, the methods include reducing contaminants in a portion of a patient that has an implant and that is disposed interior to a closed surface of skin of the patient. The method can further include placing a conduit in the closed surface of skin and flowing an antimicrobial fluid into that portion of the patient to contact the antimicrobial fluid with a surface of the implant and tissue adjacent to the implant. In some cases, the antimicrobial fluid is then removed from the portion of the patient having the implant. As part of this method, biofilm near the implant can be mechanically, ultrasonically, electrically, chemically, enzymatically, or otherwise disrupted. Other implementations are described.

A metabolic analyte sensor includes a substrate having an electrically conductive surface, an interference layer on the conductive surface, an enzyme layer on the interference layer, and a glucose limiting layer on the enzyme layer. The interference layer or the enzyme layer is configured such that the metabolic analyte sensor has an improved performance characteristic after sterilization compared to before sterilization. A packaged continuous metabolic monitor includes a sealed container; a metabolic sensor in the sealed container for insertion into a patient after the metabolic sensor is removed from the sealed container, the metabolic sensor comprising a conductive surface and an enzyme layer; electronic operating circuitry in the sealed container and coupled to the metabolic sensor; and a residue of a sterilizing gas in the metabolic sensor. The sealed container, the metabolic sensor and the electronic operating circuitry are sterilized together in the sealed container using the sterilizing gas.
