Therefore, it can suppress that the chemical | medical solution D adheres to skin, or mixes and reacts with another substance, and can replenish the chemical | medical solution D safely and easily.

In addition, according to the present invention, by using carbon dioxide gas as the gas and adopting a solution containing hypochlorous acid as the chemical solution D, it is possible to easily obtain sterilized water whose pH is adjusted. That is, by mixing a sodium hypochlorite aqueous solution and carbonated water (carbonated spring) in which carbon dioxide gas is mixed with water, sterilized water having a pH preferable for use on the human body can be easily obtained.
