Description

Endoscope disinfection device using chlorine dioxide gas {Device for disinfecting endoscope using chlorine dioxide gas}

The present invention relates to an endoscope disinfection device using chlorine dioxide gas, and more specifically, to an endoscope disinfection device using chlorine dioxide gas that can easily and quickly disinfect a used endoscope by generating chlorine dioxide gas.

In general, an endoscope is a medical device that can examine the inside of the human body or perform procedures simultaneously with the examination. These endoscopic instruments include gastrointestinal endoscopes and enteroscopes, which are gastrointestinal endoscopes for treating and examining the human stomach or intestines, and nasal endoscopes and otoscopes for treating and examining the ears and nose in otolaryngology, etc.

Since these endoscopes are inserted into the body and used especially for examination and treatment purposes, cleaning and disinfection processes must be performed in order to use them again after use.

Conventionally, the immersion disinfection method was mainly used to sterilize endoscopic instruments. In the case of immersion disinfection, endoscopic instruments are sterilized by immersing them in a general container containing a disinfectant solution, and because there is no dedicated disinfection device, systematic and complete disinfection is not achieved.

In order to solve this problem, Korean Patent No. 10-1311820 has disclosed a technology related to a circular vortex spray-type endoscope washer-disinfector and its cleaning-disinfection process. However, this invention only uses a certain amount of disinfectant (disposable disinfectant). There is a problem that cost savings due to reuse of disinfectants are not achieved by discarding them after only one use.

In addition, conventionally, endoscopic instruments must be rolled into a circle and placed in an automatic endoscope washing machine for cleaning and disinfection. After cleaning and disinfection are completed, the endoscope instruments must be taken out and stored in an endoscope storage box equipped with a built-in ultraviolet ray light and ventilation device, so they are moved from the disinfector to the storage box. Contamination by human hands occurs, and a double endoscope sterilizer and storage box must be purchased.

In order to solve this problem, Korean Public Utility Model No. 20-2014-0005110 announced technology for endoscope disinfection and storage, but the invention cannot disinfect multiple endoscope instruments at the same time, making it difficult to sterilize individual endoscope instruments. There is a problem that it takes a long time.
