Description
Technical Field
The invention relates to a sterilization device, in particular to an atmospheric pressure low-temperature plasma rapid sterilization device taking an instrument to be sterilized as an electrode.
Background
With the continuous development of the field of medical instruments, high-precision electronic instruments and optical instruments in the medical instruments are more and more, the value is high, the use frequency is high, and many instruments are not suitable for the traditional damp-heat sterilization mode or the traditional sterilization mode and can not meet the clinical use and the requirements on instrument protection. While the sterilization and disinfection supply room of each clinic department and the center of the hospital in the hospital has a great deal of sterilization requirements for the instruments.
The plasma is a particle set composed of electrons, ions and neutral particles, and the whole body presents electric neutrality to the outside. The low temperature plasma is typically generated by ionizing a gas by an electric field. Because the low-temperature plasma does not burn the treated objects due to the specific higher electron energy and lower gas temperature, and contains a large amount of active atoms, molecules, free radicals and the like, the low-temperature plasma is very favorable for the chemical reaction, and therefore, the low-temperature plasma has wide application in the fields of waste treatment, chemical synthesis, material treatment, biomedicine and the like.
For the conventional mode of pathogenic microorganism inactivation, the traditional damp heat sterilization mode such as pressure steam has higher temperature of about 121.3 ℃, so medical instruments which are not resistant to high temperature cannot be sterilized, and the sterilization period is long, namely about 15-30 minutes. And after autoclaving, it is dried before use. Therefore, the sterilization requirements of the departments of the clinics of the hospitals cannot be met. If ethylene oxide sterilization is used, the sterilization effect of this mode is greatly affected by temperature and relative humidity, and ethylene oxide is flammable, explosive and toxic to humans, so it is necessary to carry out in a closed ethylene oxide sterilizer. The ethylene oxide sterilization procedure comprises preheating, prewetting, vacuumizing, introducing vaporized ethylene oxide to reach a predetermined concentration, maintaining the sterilization time, removing ethylene oxide gas in the sterilization cabinet, and resolving to remove residual ethylene oxide in the sterilized articles. On the other hand, ethylene oxide requires ventilation after sterilization, typically 24 hours. Therefore, the sterilization process using ethylene oxide is complicated, has a certain potential safety hazard, and cannot meet the sterilization time requirement of hospitals.
The existing hydrogen peroxide low-temperature plasma sterilizer is used for sterilizing medical instruments in the market, the pretreatment links are more, the cost is high, the sterilization period is long and is about 45-50 minutes, and meanwhile, the negative pressure vacuum can influence the performance of some high-precision instruments, so that the application range of the medical instruments is limited.
In patent CN106693009a, an atmospheric pressure flexible cold plasma jet endoscope sterilization method is presented. The main characteristic is that the catheter type sterilizing area is non-closed and independent from the plasma electrode discharging area. In this way, the sterilization efficiency may be affected due to the fact that the sterilization area is separated from the discharge area by a certain distance. If the instrument can be directly used as an electrode, the operation is simple and convenient, and meanwhile, the plasma with higher density can be generated around the instrument for high-efficiency sterilization, but the low-temperature plasma sterilization device cannot be realized until now.
