随着社会的发展,医疗器械的材质要求越来越高,成本也随之增高,经有效处理后可以重复使用的医疗器械的复用也成为了一种趋势,它既能降低成本,减轻患者的负担,又能减低废物的排放,利于环保[1]。现代医疗的进步,手术种类和手术量的增多,意味着器械的重复使用率也增加,如果器械清洗不到位,器械表面残留的无机物、有机物会阻碍消毒剂或灭菌剂与其表面的接触,病菌深藏不易被杀灭,器械再次使用于别的患者时,极易造成医源性感染[2]。因此,医疗器械在使用后,要 With the development of society, the material requirements of medical devices are higher and higher, the cost is also increased, and the reuse of medical devices that can be reused after effective treatment has also become a trend, which not only reduces costs and lightens patients The burden, but also reduce waste emissions, conducive to environmental protection [1]. The progress of modern medical treatment, the type of surgery and an increase in the amount of surgery, means that the repeated use of equipment also increased, if the equipment is not in place, the surface of the instrument residual inorganic matter, organic matter will hinder the disinfectant or sterilant contact with the surface, Pathogenic bacteria can not easily be killed, the device used again in other patients, can easily cause iatrogenic infection [2]. Therefore, the medical equipment after use, to
