PROBLEM TO BE SOLVED: To detect the blood pressure and the presence or absence of arrhythmia at the same time by simple operations and to alleviate a burden on a subject.SOLUTION: After pneumatically pressurizing a cuff belt wrapped around an upper arm of a subject in a predetermined manner, when the pressure is reduced, the pulse wave under pressure of the subject is detected by a strain sensor 7. By analyzing a frequency component including Korotkoff sounds from the detected pulse wave under pressure, the systolic blood pressure and the diastolic blood pressure are measured and the presence or absence of arrhythmia is detected from the cycle of the pulse wave under pressure. The systolic blood pressure, the diastolic blood pressure and the presence or absence of arrhythmia are indicated on a systolic blood pressure display 21f, a diastolic blood pressure display 21g and an arrhythmia warning display 21i which are arranged in a display section 21d of a portable phone 21.COPYRIGHT: (C)2014,JPO&INPIT【課題】簡単な操作で血圧と不整脈の有無とを同時に検出することができ、被検者の負担を軽減することができるようにする。【解決手段】被検者の上腕に巻き付けたカフ帯を空気圧にて所定に加圧した後、減圧する際に、歪みセンサ7にて被検者の被圧迫脈波を検出し、検出した被圧迫脈波からコロトコフ音を含む周波数成分を解析して、最高血圧、最低血圧を測定すると共に、被圧迫脈波の周期から不整脈の有無を検出する。そして最高血圧、最低血圧、不整脈の有無を携帯電話21の表示部21dに設けた最高血圧表示部21f、最低血圧表示部21g、不整脈警告部21iに表示させる。【選択図】図1
