<p>PROBLEM TO BE SOLVED: To highly accurately measure a blood pressure without being affected by vibration. SOLUTION: This device is provided with a cuff 1 for being put on an upper arm, a pressurizing device 10 for supplying air stepwise through a tube 2 to the cuff 1 corresponding to pressurizing signals supplied from a control part 17, a pressure sensor 12 for detecting a cuff pressure inside the cuff 1, a band- pass filter 13 for extracting pulse wave signals from the output signals of the pressure sensor 12, the control part 17 for measuring the blood pressure based on the pulse wave signals, a supporting body 40 composed by forming a vinyl bag or the like in a trapezoidal shape for supporting the upper arm to which the cuff 1 is put on at the time of measurement on the upper surface and the pressure sensor 41 for detecting the pressure inside the supporting body 40. Then, in the case that the output signals of the pressure sensor 41 change while measuring the blood pressure, the control part 17 judges that a measured result is inaccurate and measures the blood pressure again.</p> |
