目的探讨鼻镜的有效清洗方法,提高器械清洗质量,预防医院感染。方法将消毒供应中心回收的1 800件污染鼻镜随机分为试验组910件和对照组890件,试验组采用自制的鼻镜清洗摆放架+超声波清洗机+全自动清洗消毒器机械清洗,对照组采用传统摆放法+超声波清洗机+全自动清洗消毒器机械清洗,比较两组鼻镜清洗质量合格率及干燥合格率,数据采用SPSS13.0软件进行统计分析。结果试验组鼻镜目测清洗质量合格率及3M清洗测试棒清洗质量检测合格率,分别为99.78%及100.00%,对照组分别为93.94%及92.70%,两组间差异有统计学意义(P<0.01);试验组鼻镜干燥合格率为99.89%,对照组为91.80%,两组间差异有统计学意义(P<0.01)。结论超声波清洗机及全自动清洗消毒器机械清洗时,采用鼻镜清洗摆放架装载鼻镜,使鼻镜咬合面和轴节被最大限度地打开,鼻镜摆放相互不重叠,提高了鼻镜清洗及干燥质量,延长了器械使用寿命。
Objective To explore the effective method of nasal cleaning, improve the quality of instrument cleaning and prevent nosocomial infection. Methods A total of 1 800 contaminated nose collected by disinfection and supply center were randomly divided into experimental group (910 cases) and control group (890 cases). The experimental group adopted self-made nose-mounted cleaning stand + ultrasonic cleaning machine and automatic cleaning disinfection machine, The control group was mechanically cleaned by the traditional method of placement + ultrasonic cleaning machine + automatic cleaning and disinfecting machine. The quality of pass rate and dry pass rate of two groups were compared. The data were analyzed by SPSS13.0 software. Results The qualified rate of nasal visual inspection washing quality and 3M washing test bar cleaning quality test were 99.78% and 100.00% in the test group and 93.94% and 92.70% in the control group, respectively, with significant difference between the two groups (P < 0.01). The qualified rate of nasal drying in test group was 99.89% and that in control group was 91.80%. There was significant difference between the two groups (P <0.01). Conclusion Ultrasonic cleaning machine and automatic cleaning and disinfecting machine cleaning, the use of nose mirror cleaning rack mounting nose mirror, the nose occlusal surface and shaft section is opened to the maximum, nose mirror placement do not overlap each other, improve the nose Mirror cleaning and drying quality, extending the service life of equipment.
