摘要
自2020年1月武汉新型冠状病毒感染肺炎疫情暴发以来,医用一次性防护服等医疗卫生用品的需求量急剧增加,因此,需要采用快速高效的灭菌工艺以缩短供货周期。辐射加工行业在中国同位素与辐射行业协会(下称协会)的组织下,利用钴源和加速器辐照装置为送往疫区的防护服等物资提供快速辐照灭菌服务。常规医用一次性防护服采用环氧乙烷灭菌工艺需要7~14 d,而辐照灭菌工艺1 d以内即可完成,大幅度缩短了防护服的灭菌时间。协会组织相关专家完成了《医用一次性防护服辐照灭菌应急规范(临时)》(中英文版)及具体操作规程的编制。大量一次性防护服已经采用辐照技术进行了灭菌处理。辐照灭菌技术预计在防护服等医疗用品灭菌中的应用将会得到更加广泛的认可。
The requirement of disposable medical protective clothing and other medial items has been increasing sharply since the novel coronavirus pneumonia(NCP/Coronavirus disease 2019,COVID-19)outbreak in January 2020 in Wuhan city,it is demanded to find a fast and reliable way to sterilize or disinfect medical protective clothing.Ethylene oxide(EO)gas has been widely adopted in China to sterilize disposable medical protective clothing,but the total period of this sterilization process normally requires 7~14 d because the release of contaminated EO from clothing takes a long time.However,ionizing radiation sterilization by gamma ray or electron beam can be completed in one day,being much faster than traditional EO sterilization.To promote radiation sterilization of medical protective clothing,China Isotope and Radiation Association(CIRA)organized national experts to draft a temporal standard of radiation sterilization of disposable medical garments by gamma ray or electron beam,in both Chinese and English versions.This standard has already been accepted by radiation sterilization service industry,a large number of medical garments have been disinfected by irradiation.Radiation sterilization is believed to be widely used in the future for disinfection of medical clothing and other items.
