Automatically-changeable rapid high-density plasma sterilization equipment

Abstract

The invention provides automatically-changeable rapid high-density plasma sterilization equipment. The automatically-changeable rapid high-density plasma sterilization equipment comprises a sterilization cavity, a high-density plasma source and a rotary worktable, wherein the high-density plasma source is arranged at the air inlet end of the sterilization cavity; the rotary worktable is arranged at the exhaust end of the sterilization cavity and is used for placing to-be-sterilized articles; the high-density plasma source comprises a heating wire, a hot cathode emission source sheet and a shielding structure arranged on the periphery of the heating wire and the periphery of the hot cathode emission source sheet; the high-density plasma source excites arc discharge plasma for sterilizing and disinfecting the to-be-sterilized articles on the rotary worktable. By means of the high-density plasma provided by the invention, the killing rate and the killing efficiency can be increased and improved; in addition, due to high energy, the high-density plasma can kill germs which cannot be killed by microwave plasma; multi-chamber linking is realized, and automatic change of low-pressure sterilization can be realized, so that the efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of low-temperature plasma sterilization and disinfection, in particular to an automatic replacement rapid high-density plasma sterilization equipment. Background technique [0002] Low pressure plasma sterilization has its own advantages over atmospheric pressure. First of all, low-pressure glow discharge plasma is relatively easy to generate, and the requirements for plasma power are relatively low. Secondly, the sterilization is carried out in a closed container, which can be directly sealed when it is taken out after sterilization, without repeating the sterilization effect, and will not affect the sterilization effect due to re-contamination of the sterilized instruments if they are not sealed in time . Thirdly, low-pressure sterilization is basically at room temperature, and will not cause damage to some rubber, plastic and other medical devices that are not resistant to high temperatures.

AI Technical Summary

Problems solved by technology

[0006] In order to solve the technical problems of low plasma density and unsatisfactory killing effect produced by the current low-pressure plasma sterilization and disinfection, the present invention provides an automatically replaced rapid high-density plasma sterilization equipment, which improves the efficiency of plasma disinfection and sterilization. The plasma density inside the sterilization equipment increases the sterilization and disinfection effect by 10 to 100 times, and it can work continuously without breaking the vacuum. The specific technical scheme is as follows:
