一款基于穿戴式的无创连续血压监测系统

Wearable Device for Non-Invasive Continuously Blood Pressure Monitoring

随着社会老龄化的到来,同时适合于居家、社区、养老院等使用的无创连续血压监测系统具有广泛的开发应用前景。基于此,该文设计了一款基于穿戴式的无创连续血压监测系统。该设计采用MSP430F5529作为中央处理器,具有超低功耗的优点,系统具体由信号采集模块、中央控制模块、显示模块、电源模块和上位机模块组成。实验表明,无创连续血压监测系统估算的舒张压(Diastolic Blood Pressure, DBP)(375/390, 96.15%)和收缩压(Systolic Blood Pressure, SBP)(377/390, 96.67%)在95%置信区间内,通过Bland-Altman检验,具有较高的准确性和稳定性。

In aging society the development of non invasive continuously blood pressure monitors which are suitable for homes, communities and nursing homes has a wide range of applications. This paper proposes a non invasive continuously blood pressure monitoring based on wearable device which uses MSP430F5529 as the central processor. The design is divided into signal acquisition module, central control module, display module, power supply module and host computer module. The experimental results showed that DBP （375/390, 96.15%） and SBP estimation values （377/ 390, 96. 67%） are in 95% confidence interval, which means our design passes Bland-Altman test with high accuracy and stability.
