PROBLEM TO BE SOLVED: To provide an electronic blood pressure monitor which acquires more minute information if a subject shows a symptom of high blood pressure which occurs in the early morning hours by neither giving a feeling of a burden on the subject nor disturbing his/her sleep.SOLUTION: The electronic blood pressure monitor includes a cuff mounted on an appropriate place of an auricle of an ear, a pressurizing means for pressurizing the cuff, a depressurizing-speed controlling means for controlling a depressurizing speed of inner pressure of the cuff, a pressure detecting means for detecting inner pressure of the cuff, a pressure determining means for determining the maximum blood pressure value (a systolic blood pressure value) and the minimal blood pressure value (a diastolic blood pressure value) based on output signals of the pressure detecting means during a process of depressurizing the inner pressure of the cuff, and a blood pressure measurement time setting means. The time set by the blood pressure measurement time setting means is set for a prescribed time before wake-up time to be set, and the pressurizing means pressurizes the cuff at 2-5 mmHg per second.COPYRIGHT: (C)2008,JPO&INPIT【課題】被検者に負担感を与えることなく、起床前において睡眠を妨げず、早朝高血圧がある場合においてもより細かい血圧情報が得られる電子血圧計の提供。【解決手段】本発明に係る電子血圧計は、耳介の適所に装着されるカフと、このカフを加圧する加圧手段と、カフ内圧の減圧速度を制御する減圧速度制御手段と、カフ内圧を検出する圧力検出手段と、カフ内圧の減圧過程で圧力検出手段の出力信号に基づいて最高血圧値(収縮期血圧値)および最低血圧値(拡張期血圧値)を決定する血圧決定手段と、血圧測定時刻設定手段とを有する電子血圧計であって、血圧時刻設定手段で設定される時刻は、設定される目覚まし時刻の所定時分前に設定され、加圧手段は、2~5mmHg/秒でカフを加圧することを特徴とする。【選択図】図2
