宫腔刮吸器超声清洗影响因素的研究

目的 探讨宫腔刮吸器超声清洗时的入水方式、多酶的添加及水温等因素对清洗效果的影响,寻找最佳清洗条件,为制订宫腔刮吸器的超声清洗规范提供科学依据.方法 选择宫腔刮吸器入水方式,清洗剂的添加与否以及清洗温度3个因素,按三因素析因设计,对宫腔刮吸器进行超声清洗,采用目测结合放大镜及检测血红蛋白残留情况来评价宫腔刮吸器的清洗效果.结果 宫腔刮吸器入水先后顺序对超声清洗的效果影响不明显;超声加清洗剂清洗的效果明显高于不加清洗剂的超声清洗;35℃与40℃温度下进行超声清洗的效果比较无显著差异.结论 宫腔刮吸器超声清洗时添加清洗剂可明显提高清洗效果,而宫腔刮吸器入水先后顺序及35℃或40℃的清洗温度对清洗效果影响不大.

Research of the influential factors of ultrasonic cleaning of curettage- aspiration device for uterine cavity

Objective To evaluate the combination influence of the factors such as the ways to putting into the water, addition with multienzyme and temperature of water on the cleaning effect of ultrasonic cleaning of the curettage-aspiration device for uterine cavity. So that we can find out the best condition for cleaning, and provide the scientific evidence for the formulation of the norm of ultrasonic cleaning of the curettage-aspiration device for uterine cavity. Methods According to the factorial design with triple pathogens, three factors were chosen to complete the ultrasonic cleaning of the curettage-aspiration device for uterine cavity, including the sequence of putting into water, addition with multienzyme or not and the temperature of cleaning. The cleaning effect was detected by adopting the eye-measurement or with the hemoglobin reagent. Results The sequence of putting into water first or next had little influence on ultrasonic cleaning;the effect of addition with multienzyme was more significant than without it;the effect of water temperature at 35 centi-degree or 40 centi-degree had no difference. Conclusions It had good benefits for the cleaning effect when the ultrasonic cleaning of the curettage-aspiration device for uterine cavity added multienzyme to the cleansing solution, while the sequence of putting into water first or next and the temperature of water at 35 centi-degree or 40centi-degree shows little influence on the cleaning effect.
