【摘要】：目的评价医疗器械保湿剂对宫腔吸引管内壁干涸污渍清洗效果的影响,为改善管腔类器械的清洗质量提供依据。方法 2014年7-8月在北京3所医院收集到符合要求的宫腔吸引管共计126件,随机分为对照组与试验组,每组63件,两组器械均于室温放置1h以上使污渍干涸,随后对照组器械直接进行手工清洗,试验组器械喷上保湿剂反应1h后清洗;采用ATP表面采样棒评价每把器械处理前后管腔内壁的污染水平,并计算处理前后污染水平的差值(ΔlogRLU),比较两组logRLU的均值。结果对照组与试验组器械管腔内壁的初始污染水平分别为(5.672±0.347)logRLU与(5.692±0.340)logRLU,两组比较差异无统计学意义;对照组与试验组器械处理前后的ΔlogRLU均值分别为(1.469±0.608)logRLU和(2.952±0.462)logRLU,对照组低于试验组,差异有统计学意义(P0.01)。结论采用医疗器械保湿剂可有效帮助宫腔吸引管内壁干涸污渍的去除,改善管腔类器械的清洗质量。
[Abstract]:Objective to evaluate the effect of moisturizing agent on the cleaning effect of dry stains on the inner wall of uterine cavity suction tube. Methods A total of 126 uterine cavity suction tubes were collected from 3 hospitals in Beijing from July to August 2014. They were randomly divided into control group and experimental group with 63 tubes in each group. The two groups were placed at room temperature for more than 1 hour to dry up the stains. Then the instruments in the control group were cleaned by hand directly, and the instruments in the test group were cleaned after spraying with moisturizer for 1 hour. The surface sampling rod of ATP was used to evaluate the contamination level of the inner wall of the tube before and after the treatment of each instrument. The difference of pollution level before and after treatment (螖 logRLU),) was calculated to compare the mean value of logRLU between the two groups. Results the initial contamination levels of the internal wall of the instrument lumen in the control group and the experimental group were (5.672 卤0.347) logRLU and (5.692 卤0.340) logRLU, respectively, with no significant difference between the two groups, and the mean values of 螖 logRLU in the control group and the experimental group were (1.469 卤0.608) logRLU and (2.952 卤0.462) logRLU, respectively, which were lower than those in the experimental group. The difference was statistically significant (P0.01). Conclusion the application of medical device moisturizer can effectively help the removal of dry stains on the inner wall of the uterine cavity suction tube and improve the cleaning quality of the tube.
