基于示波法和高斯拟合的电子血压计研究与实现

摘要

With the continuously increasing of the high blood pressure morbidity of the elderly population,the tendency of the cardiovascular patients becomes younger⁃age trend and popularization. Under this background,the previous measurement modes of the hospital clinic can’t satisfy the test requirement. With the appearance of the electronic sphygmomanometer,this phenomenon has been eased,and its efficiency is improved greatly. The portable electronic sphygmomanometer designed with the blood pressure judgment method based on the oscillography and Gaussian fitting is introduced. The hardware selection and software design process are analyzed in detail by means of the RealViewMDK development kit,and by taking STM32F103C8T6 as the core. The advantages of the vast majority of the sphygmomanometer in the market are synthesized to design an electronic sphygmomanometer with low power dissipation,short test time and high precision. The test results of this sphygmomanometer and mercury sphygmomanometer are basically matched. The sphygmomanometer has a higher practical value.%近年来高血压在中老年人群中发病率不断上升，心血管病人呈现出低龄化大众化的趋势。在这样的背景下，以往的医院诊所式的测量方式已经远远不能满足人们的测试需求，随着电子血压计的出现，这一现象才得到缓解，大大提高了效率。该文以此为着眼点，介绍以示波法和高斯拟合的血压判定方法设计的便携式电子血压计。借助RealViewMDK开发套件，以STM32F103C8T6处理器为核心，详细分析了硬件选型及软件设计流程。该文综合了市场上绝大多数血压计的优点，设计出了功耗低、测试时间短、精度高的电子血压计，测试结果与水银血压计测试结果基本吻合，具有更高的实用价值。
