Abstract
An electronic blood pressure meter including a cuff, a pressurizing means for inflating the cuff, a pressure sensing device for sensing a fluid pressure within the cuff, a pulse wave detecting device for detecting a pulse wave component included in the cuff, a systolic pressure estimating device for estimating a systolic pressure value based on the pulse wave and the cuff pressure detected in a pressurizing process, a pressurization volume computing device for computing a pressurization volume based on the estimated the systolic pressure value, a pressure decreasing device for decreasing the cuff pressure after reaching the pressurization volume, a blood vessel information detecting device for detecting blood vessel information such as pulse wave components in the pressure decreasing process, a blood pressure value determining device for determining systolic and diastolic pressure values based on the blood vessel information and the cuff pressure, a pulse wave component dispersion degree detecting device for detecting a dispersion degree of the pulse wave components obtained in the pressure decreasing process, and a pressurization volume controlling device for controlling the pressurization volume by the pressurizing device.
