定する血圧決定手段と を有することを特徴とする血圧測定装置。[Claims for Utility Model Registration] A blood pressure measuring device that measures blood pressure based on Korotkoff sounds generated from an artery by compressing a part of a living body, comprising: a cuff that compresses the part of the living body; and the artery. a pair of microphones disposed on the cuff so as to be located above the artery, each detecting arterial sounds generated from two positions on the artery and outputting a pulse sound signal representing the arterial sound; a determining means for determining the positional relationship of the pair of microphones on the artery based on a difference; and a pulse output from the microphone determined by the determining means to be located on the upstream side of the artery. gate means for limiting the passage time of the pulse sound signal output from the other microphone based on the sound signal; and arterial sound represented by the pulse sound signal inputted through the gate means as the Korotkoff sound and a blood pressure value. A blood pressure measuring device comprising: blood pressure determining means for determining the blood pressure.
