METHOD FOR MEASURING ARTERIAL BLOOD PRESSURE Russian patent published in 1997 - IPC

FIELD: medical engineering. SUBSTANCE: method involves acting upon a finger with force-measuring transducer and concurrently recording signal from pulsating wave gage. The signal value read from the force-measuring transducer is interpreted to determine pressure magnitude. Systolic pressure is measured at the moments pulsating wave signal vanishes or appears in increasing or lowering the level of action applied to the finger, respectively. Diastolic pressure is measured at the moments pulsating wave signal amplitude initially drops under condition of growing action applied to the finger or at the moment the pulsating wave signal amplitude stops growing under condition of decreasing action applied to the finger. Higher noise immunity is achieved both due to high-speed response enabling to determine pressure magnitudes twice a cycle and utilizing force-measuring transducer and pulsating wave gage signals feedback. EFFECT: increased measurement speed; high noise immunity. 3 cl, 2 dwg
