摘要： A pressure sensor gathers discrete data representing the pulse amplitude of a pulse wave signal when a cuff pressure is increased and decreased. A RAM stores the discrete data of the pulse amplitude. A CPU processes the discrete data by using a spline function, to thereby generate the data representative of a smooth continuous line passing by points of the pulse amplitude of the discrete data. This process reduces a variation of the pulse amplitude of a pulse wave signal, to thereby minimize a variation of the blood pressure values. An inflection point of the smooth continuous line is used as a diastolic blood pressure value.

摘要： A CPU of a control unit receives a blood pressure pulse wave signal, through an AC amplifier and an A/D convertor. The CPU differentiates, for the smoothing of the waveform, the heart pulse wave signal every step of decreasing the pressure in the cuff, thereby detecting a descending zero-cross point m of the differential wave. Further, the CPU detects a slope peak point P' while tracing back from the descending zero-cross point m. The CPU determines the peak points of the pulse wave by using the heart pulse wave signal that is not differentiated. Thereafter, the CPU determines the base points of the pulse wave tracing back from the maximum-slope point, determines the peak value of the heart pulse wave signal in all the steps of decreasing the pressure in the cuff, and finally computes a systolic blood pressure and a diastolic blood pressure.
