摘　　要：目的探讨玻璃仪器气流烘干器用于干燥氧气湿化瓶的实用性和可行性。方法将从病房回收的氧气湿化瓶120个随机分为自然晾干组30个,烘干器烘干组（下称烘干组）90个。统一消毒冲洗干净后,自然晾干组湿化瓶倒置插于晾干架上,在室温下晾干;烘干组分3批各30个分别选用46~55℃、56~65℃、66~75℃倒置插于烘干器上烘干。结果自然晾干组干燥所需时间24 h;烘干组46~55℃、56~65℃、66~75℃3个温度档干燥所需时间分别为1.5 h、1.0 h、0.5 h,但后者变形率达56.7%;干燥密封包装后第5、7天烘干组细菌培养阴性率显著高于自然晾干组（P〈0.05,P〈0.01）。结论玻璃仪器气流烘干器以56~65℃干燥氧气湿化瓶,有效缩短了干燥时间,保障了消毒效果。Objective To explore the feasibility of drying oxygen humidifier bottles by using air-flow dryer for glass apparatus.Me-thods A total of 120 oxygen humidifier bottles recycled from the wards were randomized into a control group of 30 and an air-flow group of 90.All the bottles were disinfected and then rinsed with running water.The bottles in the control group were placed on racks with the opening of the bottles downwards and dried naturally.The bottles in the air-flow group were placed on the heating bars of the air-flow dryer for glass apparatus,and the heating temparatures were adjusted to 46-55℃ for the first batch,56-65℃ for the sedcond batch,and 66-75℃ for the third batch respectively,with each batch having 30 bottles.Results It took 24 h for the control group to dry completely,and it took 1.5 h,1.0 h and 0.5 h respectively for the first,second and third batch of the air-flow group to dry.However,56.7% of the 3rd batch bottles became out of shape.After drying,all the bottles were sealed for storage,and on the 5th and 7th storage day,the air-flow group had higher rates of negative results of bacterial culture than the control group did（P〈0.05,P〈0.01）.Conclusion Drying length of oxygen humidifier bottles can be shortened by staff′s using air-flow dryer for glass apparatus which guarantees the disinfection effect.
