摘要
目的:提供一种能够快速、准确配制所需浓度高锰酸钾坐浴溶液的简易装置,解决浓度偏差问题。方法:根据不同浓度高锰酸钾溶液所呈现颜色不同的特点,设计出一种基于目测比色法原理的简易装置并验证其效果。将103份拟配制的高锰酸钾坐浴溶液随机分成试验组51份和对照组52份,分别采用该装置及传统目测法配制不同浓度的高锰酸钾溶液,比较其两组方法的准确率。结果:试验组配制高锰酸钾坐浴溶液浓度的准确率为90.2%,显著高于对照组的65.4%(x2=4.60,P<0.05)。结论:使用该装置配制高锰酸钾坐浴溶液准确、便捷、直观,优于传统目测法。
Objective：To provide a new type of simple device which can compound desired sitz bath solution of potassium permanganate for medical staff.Methods：According to the characteristic that different concentration of potassium permanganatevisual solution presents a certain color,a novel apparatus which was based on visual color measurement principles was designed.The using effect was observed.103 solutions of potassium permanganate were divided into 51 of test group and control group of 52 randomly.The device was used in test group and the traditional visual method was used in control group,and 0.1%,0.5%,1.0% and 2.0% potassium permanganate solutions were compounded respectively.The accuracy of two groups was compared.Results：The accuracy of test group was 90.2%,and the accuracy of control group was 65.4%（x2=4.60,P0.05）.Accuracy of the test group is significantly higher than the control group.Conclusion：It was accurate,convenient and intuitive that the equipment was applied to compound sitz bath solution of potassium permanganate and it was superior to the conventional visual method.
