DISINFECTION METHOD OF OZONE WATER DISINFECTION MACHINE

摘要

To propose a disinfection method of an ozone water disinfection machine for determining whether a detergent is input into raw water or not, without arranging a sensor newly.SOLUTION: Cleaning disinfection treatment operation of an endoscope 10 by an endoscope disinfection machine 1 has detergent cleaning operation (step ST12) for detergent cleaning the endoscope 10 by cleaning water generated by injecting a detergent into raw water, and a disinfection process (step ST5) for disinfecting the endoscope 10 by ozone water generated by injecting ozone gas into the raw water. In the detergent cleaning process (step ST12), an inspection light of an ozone concentration meter 45 is irradiated to the cleaning water, and presence or absence of injection of the detergent into the raw water is determined based on a signal from the ozone concentration meter 45. The ozone concentration meter 45 is mounted in the endoscope disinfection machine 1 for adjusting an ozone concentration of the ozone water in the disinfection process (step ST5).SELECTED DRAWING: Figure 7
