An endoscope washer using a moving brush module

Endoscopy is a medical device used for examining organs or treating affected areas in side of body. However, there is the possibility a chance of infection by viruses and bacteria due to the direct contact with the mucous membrane and blood, so it is required high-intensive disinfection in order to prevent secondary infection. The conventional cleansers are inefficient and complicated to use because of reassembly of equipment. This research aimed at developing a cleanser which has a built-in drying function to overcome these inconveniences. In the results of experiments with colitis germs, sterilizing power was 67% when 0.4ppm ozone water was used as an antiseptic solution, 7% when 1.2ppm ozone water, and 99.5% when 70% EtOH. EtOH showed the most efficient method of sterilization.
