Blood pressure monitoring using a traditional arm cuff device is often inconvenient and possibly painful. We present a miniature cuffless tonometric finger probe system, that uses the oscillometric method to measure blood pressure (BP). A small enough device could be used for convenient ambulatory measurement and be worn during sleep with minimal discomfort. In addition to BP, the device is able to collect arterial pulse wave data that can further be used to derive other cardiovascular parameters, such as heart rate (HR), heart rate variability (HRV) and central aortic systolic pressure (CASP). The device uses a motor controlled press that is used to apply pressure to the finger tip to measure the oscillometric response. We verified the functionality of the device by proof-of-concept measurements. Lastly we evaluate methods for further developing the concept and discuss the future directions.
使用传统臂带式血压监测设备往往不方便,而且可能会带来疼痛。我们提出了一种微型无袖套式血压测量指套探头系统,它采用示波法来测量血压 (BP)。这种足够小的设备可以用于方便的日常活动测量,并且在睡眠时佩戴时几乎没有不适感。除了血压,该设备还能够收集动脉脉搏波数据,这些数据可进一步用于推导其他心血管参数,如心率 (HR)、心率变异性 (HRV) 和中心主动脉收缩压 (CASP)。该设备使用电机控制的按压器,用于向指尖施加压力以测量示波响应。我们通过概念验证测量来验证设备的功能。最后,我们评估了进一步开发该概念的方法,并讨论了未来的方向。
