<p>PROBLEM TO BE SOLVED: To provide an electronic manometer reducing discomfort due to the compression of a cuff and allowing measurements to be taken easily by reducing measurement time. SOLUTION: Using changes in pulse waveform which varies depending on the relationship between the pressure of a cuff 1 (pressure application means) and a human blood pressure value, the time during which an amplitude- normalized pulse waveform proportional to changes in pressure of the cuff 1 is equal to or greater than a certain height is determined and the blood pressure value is determined from variations of the time. Thus, an electronic manometer can be provided which can accurately determine blood pressure value even if pressure reduction speed is increased, and which allows measurements to be taken easily with burdens reduced as the result of a reduction in the compression time of the cuff 1.</p> |
