使用容积补偿法,对非卧床患者从手指根部间接逐拍测定动脉压及其波形而设计了一种便于携带的装置。装置组成:(1)一种发射红外光电的容积描记器(TIPP)用于探测动脉容积的变化;(2)一种带有调节器的脉压带;(3)一种控制脉压带压力的伺服系统;(4)一台立体声测盒式录音机。动脉压由脉压带的压力所测定,脉压带的压力受伺服系统控制,以便使血管无负荷状态时维持动脉容积的稳定。这种设备装有一种补偿器,可对于心脏和手指间的静压差给予补偿。因此,对于任何手
Using volumetric compensation, a portable device was designed to measure the arterial pressure and its waveform indirectly in the ambulatory patient from the root of the finger. The device consists of: (1) a TEP for detecting arterial volume changes; (2) a pulse pressure zone with a regulator; (3) a pulse pressure control Servo system; (4) a stereo test cassette recorder. Arterial pressure is measured by the pressure in the pulse pressure zone and the pressure in the pulse pressure zone is controlled by the servo system to maintain the stability of the arterial volume when the vessel is in a non-loaded state. The device is equipped with a compensator that compensates for static pressure differences between the heart and fingers. So for any hand
