BLOOD PRESSURE MEASUREMENT APPARATUS AND BLOOD PRESSURE MEASUREMENT METHOD
First Claim
1. A blood pressure measurement apparatus, comprising:
- a blood pressure measurement unit that measures blood pressure of a subject;
a bio-information acquisition unit that continuously acquires bio-information of the subject;
a depth calculation unit that repeatedly calculates a depth index indicating a sleep stage of the subject on the basis of the acquired bio-information;
a storage unit in which the calculated depth index is stored; and
a decision unit that decides whether the sleep stage of the subject in sleep satisfies a predetermined 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,wherein the blood pressure measurement unit measures the blood pressure when the decision unit decides that the sleep stage satisfies the condition.

Abstract
A 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.

5. A blood pressure measurement apparatus, comprising:
-
a blood pressure measurement unit that measures blood pressure of a subject; a bio-information acquisition unit that continuously acquires bio-information of the subject; a depth calculation unit that calculates a sleep stage of the subject on the basis of the acquired bio-information; a storage unit in which a reference sleep stage indicating a predetermined sleep stage is stored; and a decision unit that decides whether the sleep stage of the subject in sleep has remained in the reference sleep stage for a predetermined time, on the basis of the reference sleep stage stored in the storage unit and the sleep stage calculated by the depth calculation unit, wherein the blood pressure measurement unit measures the blood pressure when the decision unit decides that the sleep stage of the subject in sleep has remained in the reference sleep stage for the predetermined time. - View Dependent Claims (6, 7, 8, 10, 12, 14, 16, 18, 20)

22. A method of measuring blood pressure, comprising:
-
acquiring as a preliminary process first bio-information of a subject in sleep thereby calculating a first depth index indicating a sleep stage of the subject; storing the calculated first depth index; acquiring second bio-information of the subject in sleep thereby calculating a second index indicating the sleep stage, the second bio-information being different from the first bio-information; deciding whether the sleep stage satisfies a predetermined condition on the basis of the stored first depth index and the calculated second depth index; and repeating the acquiring, the calculating and the deciding, and measuring blood pressure of the subject upon deciding that the sleep stage satisfies the condition. - View Dependent Claims (23, 24, 25, 27)

26. A method of measuring blood pressure, comprising:
-
measuring blood pressure of a subject; continuously acquiring bio-information of the subject; calculating a sleep stage of the subject on the basis of the acquired bio-information; and deciding whether the sleep stage of the subject in sleep has remained for a predetermined time in a reference sleep stage indicating a predetermined sleep stage, on the basis of the reference sleep stage and the sleep stage calculated in the step of calculating, wherein the step of measuring blood pressure includes measuring the blood pressure upon deciding that the sleep stage of the subject in sleep has remained in the reference sleep stage for the predetermined time. - View Dependent Claims (28)
