Electronic blood pressure meter.

摘要

An electronic blood pressure meter which measures diastolic blood pressure value is equipped with a means to extract the flat portion of the pulse wave detected in the cuff of the meter during the heart's diastolic phase; and the pressure value within the cuff at the moment when the flat portion disappears, if measured during depressurization, or when the flat portion appears for the first time, if measured during pressurization, can be considered the diastolic pressure. The flat portion is extracted from the waveform of the detected pulse wave. The cuff pressure value at the point when this flat portion vanishes (when measured during decrease of pressure) is considered the diastolic blood pressure.
