一次性使用输液器软管壁厚度的测量不确定度评定

Asessment of the Uncertainty of the Determination of Thickness of Disposable Infusion Implement/soft Tube

目的建立一次性使用输液器软管壁厚度测定方法的不确定度评定方式。方法依据JJF1059-1999确定A类及B类不确定度分量合成不确定度。结果概率p=95%自由度γ=4。结论本评定方式适用于医疗器械产品日常长度、厚度检测的不确定度评定。

OBJECTIVE To establish style of the Assessment of the uncertainty for astimation thickness of disposable infusion implement/soft tube method. METHODS According to JJF- 1999, establish TypeA standard uncertainty and Type B standard uncertainty ynthetic uncertainty. RESULTS Level of confidence p= 95%. degrees of freedom γ= 4. CONCLUSION This assessment is very suitable for thickness and length of daily medical production mensurating method.
