目的评定口腔综合治疗台回吸检测器检测回吸量的不确定度的可行性。方法分析口腔综合治疗台回吸不确定度的来源,以天津市红桥区口腔医院某一口腔综合治疗台作为单一重复测量实验单位,应用研制的回吸检测器进行10次测量,采用贝塞尔方法进行计算。结果分析得出不确定度来源为测量尺体积校准和重复测量,通过计算得出重复测量不确定度分量为0.068 7μl,体积校准不确定分量为0.064 1μl,合并后计算扩展不确定度为0.212 4μl。结论应用口腔综合治疗台回吸检测器测量回吸方便快捷,在进行不确定度评定时测量尺体积校准和重复测量均需引入计算。
Objective To evaluate the feasibility of measuring the back-suction uncertainty of oral integrated therapy unit back-suction detector. Methods To analyze the source of uncertainty of back-suction in oral comprehensive treatment unit, taking a certain oral comprehensive treatment unit in Hongqiao District Stomatological Hospital of Tianjin as a single unit of repeated measurement, the back-absorption detector was used to make 10 measurements, Method to calculate. The results obtained from the analysis of the source of uncertainty for the measurement of the ruler volume calibration and repeated measurements, calculated by the repeated measurement uncertainty component 0.068 7μl, volume calibration uncertainty component 0.064 1μl, combined calculation of expanded uncertainty of 0.212 4μl . Conclusions It is convenient and quick to measure the back-suction by the oral integrated therapy unit back-sorption detector. The measurement of the volumetric volume and the repeated measurement in the evaluation of the uncertainty should be introduced into the calculation.
