めの簡易な装置が強く要望されてきた。(Problems to be Solved by the Present Invention) It has become a problem that compressed air used in dentistry, otorhinolaryngology, etc. contains bacteria. If these germs enter the body through the mouth or nose, they can cause secondary infections. Therefore, there has been a strong demand for a simple device for sterilizing compressed air.

銀イオンの接触効果が高められる。(Operation) Compressed air is introduced into the first cylinder with the smallest diameter through the inlet, and then the compressed air is introduced into the second cylinder outside of the first cylinder through a plurality of openings provided in this cylinder. The air thus flows out into the outer cylinder, contacting the silver plated inside each cylinder, and finally out of the tank. In this way, by increasing the contact time between compressed air and silver ions, the sterilizing effect can be enhanced. In particular, the contact effect of silver ions is enhanced by the formation of turbulence in the compressed air.

It has long been known that water kept in silver vessels does not spoil, as described in ``What is Metal?'' by Savitzky. These properties of the silver container were preserved by the Yi teachers as so-called "holy water." Water in a silver container can prevent gastrointestinal diseases, and in ancient Egypt, it was also known that placing a silver plate on a wound would heal it quickly without causing suppuration.Although the amount of silver is extremely small, Soluble in water. Water is composed of negatively charged oxygen and positively charged hydrogen, and is easily soluble in ionic compounds such as salts.

る。 Compressing air produces moisture, and when this moisture collides with the silver-plated cylindrical wall, silver ions dissolve in the moisture. The above-mentioned bactericidal action of silver can completely kill fungi, bacteria, viruses, and rickettsiae contained in the air.
