A portable device for cleaning and ozone sterilization of small-sized delicate dental instruments that cannot withstand the high heat and humidity of standard autoclaving has been developed. The device contains a remote unit for magnetic mechanical washing, an ultrasonic bath for pre-cleaning treatment, and a container for ozone sterilization with a reactor based on dielectric barrier discharge. The maximum ozone concentration in water reached 8.5 mg/l for 10 min of operation at a water temperature of 19 °C. The results of inactivation of Pseudomonas aeruginosa, Escherichia coli, and Staphylococcus aureus are presented. Distilled water with such seeded micro-organisms was bubbled with an ozone-air mixture at an ozone concentration of 5.8 mg/l at 17 °C for 5 min, 10 min, 20 min, and 30 min. The maximum bactericidal effect was manifested for Pseudomonas aeruginosa cells with their total elimination within 10 min. Inactivation of Escherichia coli bacteria was monitored after 20 min of treatment, and Staphylococcus aureus-after 30 min of treatment.

带有机械和超声波清洗装置的便携式臭氧消毒装置，用于牙科

已经开发出一种便携式设备，用于对无法承受标准高压灭菌的高温和高湿的小型精密牙科器械进行清洁和臭氧消毒。该设备包含一个用于磁力机械清洗的远程单元、一个用于预清洗处理的超声波浴和一个带有基于介质阻挡放电的反应器的臭氧灭菌容器。在 19 °C 的水温下运行 10 分钟，水中的最大臭氧浓度达到 8.5 mg/l。介绍了铜绿假单胞菌、大肠杆菌和金黄色葡萄球菌的灭活结果。在 17 °C 下，将带有这种种子微生物的蒸馏水与臭氧浓度为 5.8 mg/l 的臭氧-空气混合物一起鼓泡 5 分钟、10 分钟、20 分钟和 30 分钟。铜绿假单胞菌细胞在 10 分钟内完全消除，表现出最大的杀菌效果。处理 20 分钟后监测大肠杆菌的灭活，处理 30 分钟后监测金黄色葡萄球菌的灭活。
