  • Patent number: 11534070
    Abstract: A blood pressure measurement device measures a blood pressure of a subject by a blood pressure measurement unit, detects a body sound of the subject during blood pressure measurement by a sound detection unit. The measured blood pressure and the detected body sound are recorded in association with each other by time information. The factor for the increase of measured blood pressure value can be specified by showing the chronological blood pressure measurement result along with checking the presence or absence of a body sound such as snoring etc.
