[0028]
Furthermore, the ozone generator and the ozone decomposer are housed in the storage 11, and the ozone gas generated by the ozone generator is connected to the air supply tube 12 by the air supply tube 12, thereby connecting the air supply / water supply operation unit 3a to one or more units. The ozone gas is sent to the treatment instrument insertion port 2e, and the ozone gas flows from the air supply / water supply operation section 3a and one or more treatment instrument insertion ports 2e, and the insertion section-side air supply channel 2b and the insertion section-side water supply channel. 2c, the air / water supply nozzle 2a, and the universal cord / side air supply channel 4a and the universal cord / side water supply channel 4b are circulated and exhausted into the storage 11 through the opening at each end.
[0029]
The inside of the storage 11 is in a sealed state, and the exhausted ozone gas is also used for sterilizing and disinfecting the outside of the endoscope 1. After the aging sterilization is completed, the ozone decomposing device is operated. The endoscope 1 is detoxified by decomposing ozone, and is stored in the storage 11 in a sterile state until it is used again.
[0030]
In addition, white clothing, small parts, and the like can be put in the extra space beside and below the storage 11, and at the same time, sterilization and disinfection can be performed.
[0031]
【The invention's effect】
In the method for disinfecting and disinfecting an endoscope of the present invention, the suction operation unit of the endoscope after cleaning is closed, and ozone gas is supplied from an air / water supply operation unit and one or more treatment tool insertion ports. The ozone gas can be circulated through the insertion section-side air supply channel, the insertion section-side water supply channel, the universal cord-side air supply channel, and the universal cord-side water supply channel by injecting from the air supply / water supply operation section. By injecting from a plurality of treatment tool insertion ports, ozone gas can be circulated through one or more insertion part side suction / treatment tool insertion channels and the universal cord side suction channel, and further, each channel is The ozone gas after the disinfection is filled in the storage and disinfects all parts including the outside of the endoscope. Is harmless ozone by the ozone decomposing apparatus, remains unchanged as to store in a sterile state vault, high innovative and practical invention.
