<p>PURPOSE: To provide a blood pressure meter capable of accurately measuring average blood pressure and diastolic blood pressure by reducing variation of blood pressure by pulse wave height value fluctuation by obtaining a smooth continuous curve passing adjacency of a pulse wave height value. CONSTITUTION: Discrete wave height value data obtained together with increasing and decreasing cuff pressure detected by a pressure sensor 2 of this blood pressure meter and stored in RAM 13c are processed by CPU 13b with spline function and creates smooth continuous curve data passing adjacency of the discrete pulse wave height value. By this processing, variation of pulse wave height values can be reduced. Furthermore, diastolic blood pressure is measured by inflection points of the continuous curve data.</p> |
