目的通过对献血环境采用超薄空气洁净屏消毒效果分析,探索献血环境消毒的新方法,以提高消毒的有效性。方法对机采血细胞室使用洁净屏的消毒效果进行随机监测,计算空气细菌菌落总数及杀菌率。结果空气洁净屏应用于血小板采集室、储存室30min杀菌率达39.6%、100.0%;消毒后9h内血小板采集室空气菌落总数为(136.6±87.6)CFU/m3,80.8%达到Ⅱ类环境要求、3.8%达到Ⅰ类环境要求;血小板储存室空气菌落总数为(55.5±95.3)CFU/m3,70.6%达到Ⅰ类环境要求、有29.4%达到Ⅱ类环境要求;动态监测43次,100.0%符合Ⅲ类环境要求,91.0%达到Ⅱ类环境要求,而且正常工作状况下(采集室<20人),随时间延长空气菌落数无明显上升趋势。结论应用超级洁净屏对机采血细胞室进行空气消毒,不仅杜绝了血小板细菌感染途径,良好的静音效果及无臭氧泄漏,为献血者提供了良好的捐献环境,建议在采血车、献血屋推广应用。
Objective To explore the new method of disinfection in blood donation by using the ultra-thin air clean screen to disinfect blood donation environment to improve the effectiveness of disinfection. Methods Randomly monitor the disinfection effect of using clean screen in the collecting room of blood cells and calculate the total number of airborne bacteria and the sterilization rate. Results The air clean screen was applied to the platelet collection chamber. The sterilization rate of the storage chamber reached 39.6% and 100.0% after 30 min. The total number of air colonies in the platelet collection chamber within 9 h after disinfection reached 136.6 ± 87.6 CFU / m3 and 80.8% 3.8%, respectively. The total number of air colonies in platelet storage room was (55.5 ± 95.3) CFU / m3 and 70.6%, reaching class I environment requirements and 29.4% met Grade II environment requirements. Dynamic monitoring of 43 cases and 100.0% 91.0% met Grade II environmental requirements, and under normal working conditions (collection room <20 persons), there was no obvious increase in the number of airborne colonies over time. Conclusion The application of super clean screen air disinfection of the machine room blood cell, not only put an end to bacterial pathways of platelet infection, good mute effect and no ozone leakage, provide a good donation environment for blood donors, it is recommended in blood collection vehicles, blood donation promotion application .
