为探讨８４ 消毒液对日常医疗器械消毒的最佳浓度及放置时间，以确保其消毒效果，将８４ 消毒液配制成０－５％ 、１－０％ 、１－５ ％ 、２－０ ％ ４ 种浓度，检测不同时间消毒液中的氯含量及细菌培养阳性数，同时采用酶联免疫吸附法检测４ 种浓度对ＨＢｓＡｇ 的杀灭力。结果，４ 种浓度的８４ 消毒液随时间延长有效氯含量下降；２４ ｈ 后，０－５ ％ 、１－０％ 组检测细菌阳性数逐渐增多；２－０ ％ 对ＨＢｓＡｇ 杀灭力最强。提示２－０％ ８４ 消毒液浸泡消毒体温计，７２ ｈ 更换１ 次，可达到灭菌效果。
In order to explore the best disinfectant 84 disinfectant daily disinfection concentration and storage time to ensure that the disinfection effect, the 84 disinfectant formulated 0-5%, 1-0%, 1-5%, 2-0% 4 The concentration of chlorine in disinfectant and the positive number of bacteria culture were detected at different time. At the same time, the killing force of 4 concentrations on HBsAg was tested by enzyme-linked immunosorbent assay. As a result, the concentrations of 84 disinfectant decreased with the passage of time. After 24 h, the positive numbers of bacteria in 0-5% and 1-0% groups increased gradually, while that of 2-0% killed HBsAg the strongest. Tip 2-0% 84 disinfectant immersion disinfection thermometer, 72 h replacement 1, sterilization can be achieved.
