We have adopted a system that obtains clean water used for cleaning and cleaning from the tap water. As an example thereof, a system is known in which tap water is directly purified by a dust / sterilization filter, or a system in which water is sterilized and further purified by a dust / sterilization filter. However, in these systems, the back suction of clean water occurs at the moment of stopping the water supply, saliva, blood,
Inhaled contaminated water etc., this saliva inhaled,
Bacteria in blood, contaminated water, etc. often reverse-contaminate the supply pipeline, turbine head, three-way syringe, etc.
As a cleaning device to eliminate such pollution, compressed air and water
The one in the form of Japanese Utility Model Publication No. 58-139126
Therefore, it is disclosed that this form does not
By using a structure in which water does not stay in the water circuit during use
I tried to prevent the colonization and growth of bacteria and provide a safe treatment.
Therefore, the structure is complicated, and even if there is no water,
There is a deficiency such as ineffectiveness against the bacteria that kill it .
