本文采用自主研制的可触摸式低温等离子体系统,研究了等离子体对硅胶手表面的消毒灭菌效果,以模拟和评估对人手的处理。等离子体处理硅胶手表面的金黄色葡萄球菌、大肠杆菌、白色葡萄球菌和铜绿假单胞菌时,并无显著差异。等离子体的消毒灭菌效率随时间的延长而提高,随细菌初始密度的增高而降低。细菌初始数量为1.0×10~6~1.0×10~7 CFU时,灭菌过程主要发生在前5 s,灭菌率在99%以上。本研究为研制可用于人手的新型等离子体设备奠定了基础。
In this paper, self-developed low-temperature plasma system can be touched, the plasma on the silicone rubber surface disinfection sterilization effect to simulate and evaluate the treatment of manpower. There was no significant difference in the plasma treatment of Staphylococcus aureus, Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa on the silica gel watch. Plasma disinfection and sterilization efficiency increases with time, with the increase of initial bacterial density decreased. When the initial bacterial count was 1.0 × 10 ~ 6 ~ 1.0 × 10 ~ 7 CFU, the sterilization process occurred in the first 5 s, and the sterilization rate was above 99%. This study lays the foundation for the development of new plasma equipment that can be used for manpower.
