  • Patent number: 8968651
    Abstract: By focusing on the fact that nitrogen dioxide exhibits an increased sterilizing effect among other sterilant gases including nitrogen oxide, the present invention is made to provide a sterilization method which may be suitably used for sterilizing items to be sterilized such as medical instruments which require increased reliability by using a high concentration NO2 gas of 5,000 ppm or above, for example. An inside of a sterilizing chamber containing an item to be sterilized is humidified, and a concentration of NO2 in the sterilizing chamber is made to be from 9 to 100 mg/L by filling a high concentration NO2 gas.

  • Patent number: 8580086
    Abstract: A high concentration NO2 gas generating system including a circulating path configured by connecting a chamber, a plasma generator, and a circulating means, wherein NO2 is generated by circulating a gas mixture including nitrogen and oxygen in the circulating path is provided. The high concentration NO2 gas generating system provides a high concentration NO2 generating system and the high concentration NO2 generating method using the generating system by which NO2 of high concentration (approximately 500 ppm or above) required for a high level of sterilization process in such as sterilization of medical instruments can be simply and selectively obtained. In addition, since indoor air is used as an ingredient, the management of ingredients is simple and highly safe, and the high concentration of NO2 can be simply and selectively prepared on demand.
