氧气湿化瓶消毒后保存期的研究

摘要

目的通过对氧气湿化瓶化学消毒后保存期进行研究，以明确其保存有效期。方法将240个氧气湿化瓶化学消毒后分别保存于5个临床科室，保存时间180 d,每月进行细菌学监测。结果氧气湿化瓶化学消毒后保存30、60、90、120、150、180 d细菌监测结果均≤20 CFU/件，未检出致病菌,合格率100%。结论氧气湿化瓶化学消毒后用保鲜袋单独包装，做好保存环境管理，其保存期最少6个月。%Objective To explore the shelf life of oxygen moisture bottle after chemical disinfection and to make clear its validity. Methods A total of 240 oxygen moisture bottles after chemical disinfection had been stored in clinical departments for 180 days and bacteriological monitoring was carried out every month. Results Bacteria monitoring 30, 60, 90, 120, 150 and 180 days after chemical disinfection showed there was 20 or less cfu/per piece and no pathogenic bacteria was found, with a qualification rate of 100%. Conclusion Once oxygen moisture bottle is packaged by plastic bag individually and stored in friendly environment, the shelf life of it after chemical disinfection could last for at least 6 months.
