口腔科的治疗工作离不开牙钻手机,而手机在应用过程中必然沾上病人的唾液或血污,这是口腔科医源性交叉感染的主要途径。过去各厂家所生产的手机不能承受高热和高压灭菌,以致长期以来只能用酒精棉球擦拭。我科曾试用40%甲醛熏蒸办法来处理污染的手机,其消毒效果也不理想。自1984年我科开始使用北京长安仪器厂生产的CA-13型高速涡轮牙钻手机,置于蒸溜水中煮沸30 min后即可使用,做到了一人一牙钻手机。经过两年的临床观察及实验研究,证明消毒效果良好,基本上解决了牙钻手机交叉感染的问题。本文主要报道酒精擦拭、甲醛熏蒸及煮沸三种消毒手机方法的比较研究资料。材料与方法
Stomatological treatment can not be separated from dental drills, and mobile phones inevitably come into contact with the patient’s saliva or bloodstains during the application process, which is the main source of stomatology-based cross-infection. In the past, cell phones produced by various manufacturers could not withstand high heat and pressure sterilization, so that they could only be rubbed with alcohol cotton balls for a long time. Our department has tried 40% formaldehyde fumigation to deal with contaminated cell phones, and its disinfection effect is not satisfactory. Since 1984, our department began to use the CA-13 high-speed turbine dental drill produced by Chang’an Instrument Factory in Beijing. After being boiled for 30 min in distilled water, we can use it as a dental handpiece for one person. After two years of clinical observation and experimental studies, the disinfection effect is proved to be good, basically solving the problem of cross-infection of dental drills. This article mainly reports alcohol wipe, formaldehyde fumigation and boiling three kinds of disinfection of mobile phone methods of comparative research data. Materials and Methods
