【摘要】 目的探讨在常规教学实验过程中碘伏使用的有效期限。方法分别将碘伏消毒剂置于18℃、25℃、30℃环境中,每日连续开启碘伏消毒液棕色瓶模拟使用10次后,取瓶内碘伏消毒液50 ml,按《消毒技术规范》2002年版推荐方法进行有效碘含量的测定。将碘伏置于54℃环境中14天后进行稳定性实验。结果在18℃、25℃、30℃环境中,14天内连续开盖使用瓶装碘伏140次后,其有效碘含量基本稳定,维持在正常范围内。将碘伏置于54℃环境中的加速实验结果显示,有效碘含量同样维持基本稳定。结论碘伏消毒液在开启瓶盖2周内使用,有效碘含量维持稳定,能够满足实验教学的需要。更多还原

【Abstract】 Objective To study the validity period of Iodophor under different temperature, different hours and different using frequency. Methods Put Iodophor disinfectant under 18℃, 25℃ or 30℃ environment respectively, opening the bottle cap of Iodophor continuous 10 times per day before taking 50 ml of Iodophor disinfectant. The accelerate test was done after 14 days putting Iodophor disinfectant under 54℃ environment. The effective iodine content was determined according to Technical Standard for Disinfection(2002). Results The effective iodine content in iodophor disinfectant remained stable after 14 days of continuous use 140 times under 18℃, 25℃, and 30℃ degrees Celsius. The accelerate test results show that the effective iodine content also remained stable. Conclusion The effective iodine content in iodophor remained stable in 2 weeks. The iodophor could meet the needs of experimental teaching.更多还原
