[0002] Currently, chlorine-containing disinfectants refer to disinfectants that dissolve in water to produce hypochlorous acid, which has antimicrobial activity. In clinical practice, chlorine-containing disinfectants are commonly used for soaking and disinfecting medical supplies. Taking bed sheets as an example, when disinfecting medical supplies, a certain volume of water needs to be placed in the disinfection bucket first. Then, chlorine-containing disinfectant tablets are put into the disinfection bucket. After the chlorine-containing disinfectant tablets are completely dissolved, the bed sheets are washed. After the bed sheets are washed, the concentration of chlorine in the disinfection bucket is tested. The chlorine concentration is used to determine whether the cleaning and disinfection of the bed sheets has met the standards.
