[0044] figure 1 It is a perspective view showing the usage state of the blood pressure measurement device 100 according to the first embodiment of the present invention.

[0045] figure 2 It is a block diagram showing the configuration of the blood pressure measurement device 100 of the present embodiment.

[0046] First, the outline of this embodiment will be described.

[0047] The blood pressure measurement device 100 of the present embodiment includes a blood pressure measurement unit 10 , a biological information acquisition unit 20 , a depth calculation unit 30 , a storage unit 40 , and a determination unit 50 .

[0048] The blood pressure measurement unit 10 is means for measuring the blood pressure value of the subject S. The biological information acquisition unit 20 is a unit that continuously acquires the biological information BI of the subject S. The depth calculation unit 30 is a unit that repeatedly calculates a depth index α indicating the sleep stage of t...

[0142] Figure 9 It is a block diagram showing the configuration of the blood pressure measurement device 100 of the second embodiment.

[0143] The blood pressure measurement device 100 of the present embodiment differs from the first embodiment in that both biological information BI and blood pressure data BP are measured using an annular belt (compression unit 12 ). The structure of the pressing part 12 is the same as that of the first embodiment shown in (a) and (b) of FIG. 3 .

[0144] The blood pressure measurement device 100 of the present embodiment acquires pulsation information (biological information BI) indicating the pulsation pressure of the arm SA of the sleeping subject S using the pressure sensor 160 at a predetermined sampling frequency. As the pulsation information (biological information BI), for example, a pulsation signal PS representing a pulsating pressure waveform and numerical data of a pulse rate can be exemplified and described.

Abstract

The invention provides an apparatus and a method capable of detecting real stable blood pressure value with excellent precision and without depending on ages and sleeping characteristics of a tested person. The blood pressure measurement apparatus includes a blood pressure measurement unit, a bio-information acquisition unit, a depth calculation unit, a storage unit and a decision unit. The bio-information acquisition unit continuously acquires bio-information of a subject. The depth calculation unit repeatedly calculates depth indices each indicating a sleep stage of the subject on the basis of the acquired bio-information. The storage unit stores the calculated depth indices. The decision unit decides whether the sleep stage of the subject in sleep satisfies a starting condition, on the basis of a first depth index stored in the storage unit and a second depth index calculated by the depth calculation unit. The blood pressure measurement unit measures blood pressure data of the subject when the sleep stage is decided to satisfy the starting condition.

Description

technical field [0001] The present invention relates to a blood pressure measurement device and a blood pressure measurement method for measuring a blood pressure value during sleep. Background technique [0002] In terms of health management, it is desirable to accurately grasp the blood pressure value. Since the blood pressure value fluctuates due to slight exercise or psychological factors after waking up, it is desirable to measure the blood pressure value of a sleeping subject in order to know the real blood pressure value. The blood pressure value during deep sleep is called the reference blood pressure, and knowing the reference blood pressure is useful for health management. Human sleep states are roughly divided into rapid eye movement sleep and non-rapid eye movement sleep, and non-rapid eye movement sleep is further divided into 2-4 stages according to the depth of sleep. It is known that an average person repeatedly performs REM sleep and non-REM sleep in a sub...
