- the plate-like portion 81 is provided with a right-eye infrared sensor 80A and a left-eye infrared sensor 80B, which are infrared ray sensors corresponding to the subject's right eye and left eye, respectively.
- a converter 82 is included for converting the output of the sensor into digital data.
- FIG. 17 is a diagram schematically showing a hardware configuration of the blood pressure measurement device 1 of FIG.
- the blood pressure measurement device 1 of the present embodiment is a blood pressure measurement device according to the first to fourth embodiments.
- a / D converters 801 and 802 for converting these outputs to digital, together with the above-described right-eye infrared sensor 80A and left-eye infrared sensor 80B.
- a / D converters 801 and 802 are included in converter 82.
- the movement mode of the eyeball is detected by the right-eye infrared sensor 80A and the left-eye infrared sensor 80B, and the sleep depth of the subject is determined based on the detected movement mode. .
- the sleep depth may be determined by a method different from the method described above.
- Examples of other methods include electroencephalogram, electrocardiogram, myoelectricity, body movement, respiratory cycle and the like as the biological information of the subject.
- the blood pressure value of the subject was measured when the sleep depth satisfied a predetermined condition.
- the blood pressure measurement device 1 was provided with a predetermined switch, The subject operated the switch immediately before going to bed, and in the blood pressure measurement device 1, a predetermined time (for example, 1 hour, 1 hour 30 minutes, 2 hours, etc.) has elapsed since the switch was operated. If the blood pressure measurement is performed on condition of Even if blood pressure is measured in this way, it is considered that blood pressure can be measured every day when the subject is in the same sleep state.
- the blood pressure value stored as the measured value is the subject.
- the depth of sleep is when a predetermined condition is satisfied. This makes it possible to measure blood pressure based on the depth of sleep of the subject, such as during non-REM sleep or waking up, which is considered suitable for measuring blood pressure.
