摘　　要：基于传统听诊法的水银血压计在我国基层医疗机构应用广泛,积累了大量血压数据却无法直接记录并应用于科研分析,而听诊法数据是验证无创电子血压计测量精度的临床标准。以此为着眼点,作者设计了一款微型无创血压测量与验证系统,配合医生自动记录听诊过程中的血压计算底层数据,系统软件可通过数据回放功能,对示波法血压算法进行评估与验证,进而不断修正算法,提高无创血压测量精度。该研究详细介绍了硬件选型及软件设计流程,进行了测试,测试结果表明该系统满足相关标准要求,具有良好的应用前景。Mercury sphygmomanometer based on traditional auscultation method is widely used in primary medical institutions in China, but a large amount of blood pressure data can not be directly recorded and applied in scientific research analysis, meanwhile auscultation data is the clinical standard to verify the accuracy of non-invasive electronic sphygmomanometer. Focusing on this, we designed a miniature non-invasive blood pressure measurement and verification system, which can assist doctors to record blood pressure data automatically during the process of auscultation. Through the data playback function,the software of this system can evaluate and verify the blood pressure algorithm of oscillographic method, and then continuously modify the algorithm to improve the measurement accuracy. This study introduces the hardware selection and software design process in detail. The test results show that the system meets the requirements of relevant standards and has a good application prospect.
