目的：观察75%酒精浸泡消毒体温计的有效时限。方法放入不同频率的体温计于75%酒精中浸泡消毒，分别于24小时、48小时、72小时测定酒精的浓度及微生物污染情况。结果在22C°的室温下，75%酒精消毒液浓度随着使用时间的延长、体温计放入频率的增加而逐渐降低，72小时染菌量小于100cfu/mL,均未检出致病菌。结论75%酒精消毒液用于体温计浸泡消毒，应该根据放入体温计的不同频率确定更换酒精消毒液的时间，室温在22C°以下，如每日放入体温计频率在20次以内，可以48小时更换一次酒精消毒液，如果每日放入体温计频率在15次以内可以72小时更换一次酒精消毒液。

Objective To observe the valid time of thermometer with 75% alcohol immersion disinfection. Method: The thermometer of different frequency was disinfected with 75%alcohol and the concentration of alcohol and microbial pol ution were measured after 24 hours, 48 hours and 72 hours. Results: At room temperature 22 ° c, the concentration of 75%alcohol disinfectant was gradual y reduced with the extension of time and the increase of frequency. The amount of bacteria was less than 100 cfu/ml and pathogenic bacteria was not detected after 72 hours. Conclusion: Whether alcohol with change was depended on the frequency of thermometer in the 75% alcohol immersion disinfection. At room temperature under 22 ° c, the alcoholic disinfectant might need to be replaced every 48 hours with frequency within 20 times and replaced every 72 hours with frequency within 15 times every day.
