消毒后备用湿化瓶的干燥方法及存放时间探讨

目的探讨消毒后备用湿化瓶干燥方法及存放时间，为其妥善保存提供依据，减少因湿化瓶保存不当而污染造成的医院内感染。方法对消毒后的84个氧气湿化瓶随机分为A组和B组各42个，分别采用自然晾干和氧气吹干2种不同的干燥方法，在不同月份连续7d进行细菌监测，并对结果进行分析。结果采用氧气吹干法的湿化瓶比自然晾干法的湿化瓶可多保存1d。结论消毒后备用湿化瓶的保存时间，应根据季节不同，干燥方法不同，确定不同的有效保存时间。

A study about the desiccation and the expiry date for humidifier after disinfection

Objective To study the proper desiccation and the expiry date for humidifier after disinfection, and then decline the incidence rate of infection in hospital. Methods Divided 84 humiditiers into the A and B groups randomly after disinfection, there were 42 humidifiers in the each group. The natural desiccation was used in the A group, the oxygen desiccation was used in the B group. Monitored the humidifiers of the two groups respectively lasted 7 days, and then compare the datum between them. Results The expiry date of the humidifiers which have dried by natural desiccation was longer than that of humidifiers which have dried by oxygen desiccation. Conclusion We should set down the expiry date for humidifier according to the different desiccation and the different seasons.
