使用容量补偿技术，设计了一种便携式设备，用于间接测量动态受试者手指基节指骨的逐搏动脉压及其波形。该装置由（1）一个传输红外光电体积描记器（TIPP）来检测动脉容量的变化，（2）一个带有执行器的气动袖带，（3）一个控制袖带压力的伺服系统，以及（4）一个立体声盒式磁带录音机。动脉压由伺服系统控制的袖带压力确定，以便在“血管卸载”状态下保持动脉容量恒定。该设备配备了一个补偿器，用于补偿心脏和手指之间的静水压差。因此，对于任何手指高度都可以获得心脏水平的血压。装置总重量为1·6kg。步行、慢跑、跳跃、侧步、师父两步测试、汽车驾驶等运动时的血压变化均已成功记录。
Using a volume-compensation technique, a portable device has been designed for the indirect measurement of beat-to-beat arterial pressure and its waveforms in the basal phalanx of fingers of ambulatory subjects. The device consists of (1) a transmission infra-red photoelectric plethysmograph (TIPP) to detect the variation of arterial volume, (2) a pneumatic cuff with an actuator, (3) a servosystem to control the cuff pressure, and (4) a stereo cassette tape recorder. Arterial pressure was determined from the cuff pressure which was controlled by the servosystem so as to maintain the arterial volume constant at the ‘vascular unloading’ state. This device is equipped with a compensator for any hydrostatic pressure difference between the heart and finger. Thus, the blood pressure at heart level can be obtained for any finger height. The total weight of the device was 1·6kg. Blood pressure changes during walking, jogging, jumping, and exercises such as side-stepping, Master's two-step test and car driving, have been successfully recorded.
