PROBLEM TO BE SOLVED: To provide a sphygmomanometer that can issue an instruction of pressurization stop by determining that manual pressurizing force to an airbag in an arm belt part mounted on an upper arm is appropriate.SOLUTION: A sphygmomanometer 1 includes: airbags 20, 40 arranged in an arm belt part 3, which supplies air to pressurize an upper arm T a pressure sensor 110 for detecting the pressure in the airbag a buzzer 114 and a control part 100 which notifies an instruction of pressurization stop by the buzzer 114 by determining that a predetermined pressurizing force is obtained by the pressurization of the arm belt part 3 after at least one pulse wave MN is detected by a pressure detection signal from the pressure sensor 110 during the pressurization of the upper arm T, when blood pressure is measured by mounting the arm belt part 3 on the upper arm T of a patient to manually pressurize the airbag in the arm belt part.COPYRIGHT: (C)2013,JPO&INPIT【課題】上腕に装着された腕帯部内の空気袋への手動での加圧力が適切であることを判断して加圧停止指示を出すことができる血圧計を提供する。【解決手段】血圧計1は、腕帯部3を患者の上腕Tに装着して腕帯部内の空気袋を手動で加圧することで血圧を測定する際に、腕帯部3内に配置されて空気を供給することで上腕Tを加圧する空気袋20,40と、空気袋内の圧力を検出する圧力センサ110と、ブザー114と、上腕Tを加圧中に、圧力センサ110からの圧力検出信号から少なくとも1つの脈波MNを検出後に腕帯部3の加圧により所定の加圧力が得られたと判断して、ブザー114により加圧停止指示の報知をさせる制御部100を有する。【選択図】図12
