This is to prevent the occurrence of inconvenient situations such as infection with pathogenic fungi via the blood attached to the injection needle or the like.

い。For sterilization and deodorization of such repeatedly used medical instruments, boiling disinfection has been performed since ancient times. However, small instruments, such as scalpels, scissors / forceps, and tweezers, are entirely made of metal. Can be applied relatively easily, but is not suitable for instruments such as endoscopes which are long and easily cause deterioration of materials.

きない。There are also many chemicals for deodorizing, deodorizing, etc., which are used in combination with adsorbents such as activated carbon, activated clay and silica gel to adsorb or neutralize odors. However, such adsorbents or neutralizers have a drawback that the period of effective function is limited and the effect gradually decreases. Further, in these, it is not possible to expect a bactericidal effect.

ており、その製法も数多くの方法が実施されている。[0006] For this reason, stabilized chlorine dioxide (ClO 2) is used in objects that need to be deodorized together with sterilization, bedding used in hospital rooms and hospitals, clothing, hospital rooms, and in ambulances.
) Evaporated solutions are also widely used. It has long been known that stabilized chlorine dioxide has a bleaching action, and many methods have been used for its production.

る。However, industrially produced high-concentration chlorine dioxide becomes a strong oxidizing agent and reacts with other substances to generate high-concentration chlorine, or the danger of explosion cannot be ruled out. Therefore, a 5% aqueous solution of stabilized aqueous chlorine dioxide is commercially available as chlorine dioxide, which is low in risk and easy to handle, and is appropriately diluted according to the application.

Exhibits various effects. The effect of sterilization and deodorization against various bacteria, molds and pathogenic fungi can be achieved in a remarkably short time.

This led to the development and commercialization of stabilized chlorine dioxide, which is an approximately 5% solution, and this problem was considerably improved. Further, such a stabilized aqueous solution of chlorine dioxide is sometimes adsorbed on a porous substance such as zeolite and used as a powder or granular material, but is not suitable for stable long-term release.
In addition, there are also restrictions on use, such as the necessity of using an alkali generating means as an activator.

ができる。The rate of evaporation from the gel-stabilized chlorine dioxide can be adjusted by the amount of ethyl alcohol contained in the gelling agent and the evaporation area of the vessel, but naturally has a significant effect on the rate of the vaporization reaction. It also depends on the amount of UV irradiation and the temperature. The stabilized chlorine dioxide changes depending on the pH, but the pH is most stable at about 9. Therefore, it is desirable to maintain the pH at about 9 by appropriately adding an alkaline substance. The stabilized chlorine dioxide gelled is advantageous for storage, transportation, handling, and the like as compared with an aqueous solution, and can be safely used in a small container.
