Abstract：
This publication presents the effect of hypochlorous acid dry mist as a disinfectant on selected bacteria, viruses, spores, and fungi as well as on portable Microlife OXY 300 finger pulse oximeters and electronic systems of Raspberry Pi Zero microcomputers. The impact of hypochlorous acid on microbiological agents was assessed at concentrations of 300, 500, and 2000 ppm of HClO according to PN-EN 17272 (Variant I). Studies of the impact of hypochlorous acid fog on electronic components were carried out in an aerosol chamber at concentrations of 500 ppm and 2000 ppm according to two models consisting of 30 (Variant II) and 90 fogging cycles (Variant III). Each cycle included the process of generating a dry mist of hypochlorous acid (25 mL/m3), decontamination of the test elements, as well as cleaning the chamber of the disinfectant agent. The exposure of the materials examined on hypochlorous acid dry mist in all variants resulted in a decrease in the number of viruses, bacteria, spores, and fungi tested. In addition, the research showed that in the variants of hypochlorous acid fogging cycles analyzed, no changes in performance parameters and no penetration of dry fog of hypochlorous acid into the interior of the tested medical devices and electronic systems were observed.
摘要：
本出版物介绍了次氯酸干雾作为消毒剂对选定细菌的影响，病毒,孢子,和真菌以及便携式MicrolifeOXY300手指脉冲血氧计和RaspberryPiZero微型计算机的电子系统。根据PN-EN17272(变体I)在浓度为300、500和2000ppm的HClO下评估次氯酸对微生物试剂的影响。次氯酸雾对电子元件的影响的研究是在浓度为500ppm和2000ppm的气溶胶室中根据由30个（变体II）和90个雾化循环（变体III）组成的两个模型进行的。每个循环包括产生次氯酸干雾（25毫升/立方米）的过程，测试元件的去污，以及清洁消毒剂的腔室。在所有变体中，次氯酸干雾上检查的材料的暴露导致病毒数量减少，细菌,孢子,和真菌测试。此外,研究表明，在次氯酸雾化循环的变体中，性能参数没有变化，也没有观察到次氯酸干雾渗透到测试的医疗设备和电子系统的内部。
