Abstract
An electronic blood pressure meter capable of performing a proper automatic pressuring operation according to a blood pressure of a subject and measuring the blood pressure rapidly with accuracy. An electronic blood pressure meter includes a cuff, a pressure controller for controlling an inside fluid pressure of the cuff, a pressure sensor for sensing the inside fluid pressure of the cuff to produce a cuff pressure detecting signal, an extracting unit for extracting a pulse wave component superposed on the cuff pressure detecting signal during pressure control operations performed by the pressure controller, a calculating unit for calculating an amplitude of the extracted pulse wave for each pressure measurement, a unit for determining a blood pressure during an evacuating operation of the pressure controller based on output signals from the calculating unit and the pressure sensor, maximum blood pressure estimating unit which obtains an estimated value of a maximum blood pressure in response to output signals from the extracting unit and the pressure sensor during the pressuring operation of the control means. The pressure controller stops the pressuring operation when the inside fluid pressure of the cuff exceeds a total pressure of the estimated value and a predetermined value.
