鼻镜自体螺丝撑开清洗装载技术设计与应用研究

Study on the design and application of nasal endoscope screw self-open cleaning loading technology

目的改良鼻镜清洗装载技术,达到既保障清洗效果,又可提高工作效率和降低清洗成本的效果。方法将480件可复用污染鼻镜按随机数字表法分为借助金属配件撑开窥叶清洗装载组(A组)和利用鼻镜自体螺丝撑开窥叶清洗装载组(B组),每组240件。经机械清洗后观察2组鼻镜的清洗效果、装载有效性、装载量,装载用时以及消毒供应中心清洗操作人员的操作满意度。结果A、B2组鼻镜的关节处清洗合格数分别为218、231例,窥叶处清洗合格数分别为214、227例,2组比较差异有统计学意义(χ^2=5.828、4.717,P<0.05);清洗装载有效数分别为211、240例,2组比较差异有统计学意义(χ^2=30.865,P<0.01);装载用时分别为(2.89±0.22)、(1.80±0.21)s/把,2组比较差异有统计学意义(t=55.535,P<0.01);62名消毒供应中心清洗操作人员操作满意数分别为51、59人,2组比较差异有统计学意义(χ^2=10.806,P<0.05)。结论利用鼻镜自体螺丝撑开窥叶的清洗装载技术,在机械清洗时使鼻镜窥叶处保持撑开状态,确保清洗效果,且装载耗时短,装载量多,从而提高工作效率和降低清洗成本。

Objective To improve the cleaning and loading technology of nasal endoscope in order to ensure the cleaning effect,to improve the working efficiency,and to reduce the cleaning cost.Methods A total of 480 reusable contaminated nasal endoscopes were divided into two groups according to random number table:Clean and load the nasal endoscopes(group A)with the usage of metal parts to open up the leaf;Clean and load the nasal endoscope(group B)with the usage of screw driver to open up the leaf.Each group has 240 pieces.After mechanical cleaning,observe and analyze the cleaning effect,loading effectiveness,loading capacity,loading time and CSSD operators′degree of satisfaction.Results The number of qualified cleaning joint parts of the two groups were 218 and 231 respectively,and the number of qualified cleaning leaf of the two groups were 214 and 227 respectively,and there were significant differences between the two groups(χ2=5.828,4.717,P<0.05).The number of effective cleaning and loading 211 and 240 respectively,and there were significant differences between the two groups(χ^2=30.865,P<0.01).The time it takes for loading were(2.89±0.22)s/piece and(1.80±0.21)s/piece respectively,and there were significant differences between the two groups.There were significant differences between the two groups(t=55.535,P<0.01).Among 62 CSSD operators,there were 51 and 59 operators in the two groups are satisfied,and there were significant differences between the two groups(χ^2=10.806,P<0.05).Conclusions Using the screw driver of the nasal endoscope helps to keep the leaf open during the process of mechanical cleaning,to ensure the cleaning effect,to shorten the loading time and increase the loading capacity.Thus improving the working efficiency and reducing the cleaning cost.
