<p>A 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 comprises a cuff (1), a pressure controller (2) for controlling an inside fluid pressure of the cuff (1), a pressure sensor (7) for sensing the inside fluid pressure of the cuff (1) 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 every pressure, a unit for determining a blood pressure during evacuating operation of the pressure controller based on output signals of the calculating unit and the pressure sensor (7) and maximum blood pressure estimating unit for obtaining an estimated value of a maximum blood pressure in response to output signals of the extracting unit and pressure sensor (7) during pressuring operation of the control means (2), the pressure controller (2) stopping the pressuring operation when the inside fluid pressure of the cuff (1) exceeds a total pressure of the estimated value and a predetermined value.</p> |
