Problems solved by technology

However, the above-mentioned DBD plasma is still limited in use, because most of the medical devices have irregular shapes, but it is difficult for the DBD plasma to cover all exposed surfaces of the above-mentioned medical devices, or it is difficult to act on some of the aforementioned medical devices. The bacteria hidden in these crevices, therefore, the effectiveness of sterilization is limited by the geometry of the object to be treated
On the other hand, hidden and residual bacteria are usually in a humid environment, such as in an aqueous solution, so it is necessary to use a sterilization technique that can ensure complete sterilization in an aqueous solution, but if DBD plasma is used to sterilize in an aqueous solution Bacteria, the difficulty will be greatly increased

Abstract

A microplasma source and a sterilization system including the same are disclosed. The microplasma source includes: a microplasma-generating unit including: a gas transmission chamber having a first inlet and a first outlet wherein the first inlet is used to import a first gas; a protection and heat dissipation chamber of which a side is connected to the inner wall of the first outlet; a dielectric inner tube having a second inlet and a second outlet and penetrating through the protection and heat dissipation chamber, wherein the second inlet is communicated to the gas transmission chamber; an electrode arranged outside at the second outlet and located in the protection and heat dissipation chamber; and a hollow metal tube disposed in the gas transmission chamber and the dielectric inner tube and having a third inlet and a third outlet, wherein the third inlet is used to import a second gas.

Description

technical field [0001] The invention relates to a micro-plasma generating device, in particular to a micro-plasma generating device and a micro-plasma sterilizing system suitable for sterilization. Background technique [0002] For reusable medical appliances, such as: when sterilizing surgical or dental appliances, it is necessary to ensure that all microorganisms attached to these appliances, whether bacteria, fungi or viruses, need to be completely removed to prevent the next Patient is infected with any possibility. However, currently known sterilization methods, such as high heat and high pressure sterilization, application of chemical bactericides such as ethylene oxide, or physical radiation irradiation, are likely to be harmful to the processed samples. cause some degree of damage or destruction. Therefore, in recent years, large-scale medical institutions have begun to adopt low-temperature and low-pressure plasma sterilization methods, that is, in a vacuum state,...
