Endoscopes are contaminated by microorganisms after each clinical use. Therefore, the whole of endoscopes should be disinfected in a high level after each patient use. However, it takes long time by manual brushing. And more over, cost of decontaminating chemicals and anxiety of their possible harms to the operators are also still there. In this connection, the Strongly Acidic Electrolyzed Water now has gotten a lot of attention recently as a new disinfectant to solve such problems.
The Strongly Acidic SANQ Electrolyzed Water has strong sterilizing power, while keeping low operation cost and high safety in usage.
There are papers about the application of the Strongly Acidic “ DENKAISUI� Electrolyzed Water for Endoscope Channel Cleaning presented at The Korean Gastroenterological Endoscopy Society ( KGES) and The Japan Gastroenterological Endoscopy Technicians Society ( JGETS) . They conclude that the strong sterilizing power can be expected with this particular water as long as operators fully understand its characteristics.

Motivated by these opportunities, KOKEN has featured Endoscope Channel Washer with an automated brushing with built in the Strongly Acidic “ SANQ� Electrolyzed Water generator.
It names " COOLENDO tm" in KOREA, meaning like " Mirror Polishoer" or " Endoscope Servant" if we give it an English pet name.

" COOLENDO tm" is equipped with not only the Strongly Acidic “ SANQ� Electrolyzed Water generator but also it has world' s first automatic endoscope channel brushing system. Thanks to this system, safety cleansing and disinfecting work on endoscopes are now available to replace of manual brushing done by medical facility workers. Moreover, drastic reduction of time with less water and energy is also achieved. Now, “ COOLENDO tm� is increasing its installation base throughout the country.
