BLOOD PRESSURE MEASURING DEVICE
First Claim
1. A blood pressure measuring device, comprising:
- a casing that is held in both hands of a user;
a pair of electrocardiographic electrodes respectively provided such as to allow contact with the hands holding the casing and which detect electrocardiographic signals through the hands;
a pulse wave sensor provided such as to allow contact with either of the hands holding the casing and which detects pulse wave signals through the hand;
a measuring section that acquires measurement information including (i) a time difference between an electrocardiographic R wave based on the electrocardiographic signals and a pulse wave reference point based on the pulse wave signals, and (ii) a pulse wave amplitude based on the pulse wave signals;
a calculating section that calculates blood pressure using the measurement information;
a display section that displays the blood pressure; and
a measurement starting section configured to enable the measuring section to start acquisition of the measurement information in a state in which contact is maintained between the hands holding the casing and the corresponding electrocardiographic electrodes and pulse wave sensor.

Abstract
In a blood pressure measuring device, a casing is held in both hands. A pair of electrocardiographic electrodes are respectively provided to allow contact with the hands holding the casing, and detect electrocardiographic signals through the hands. A pulse wave sensor is provided to allow contact with either of the hands holding the casing, and detects pulse wave signals through the hand. Based on these detected signals, a measuring section acquires measurement information including: a time difference between an electrocardiographic R wave and a pulse wave reference point; and a pulse wave amplitude. A calculating section calculates blood pressure using the measurement information. A display section displays the blood pressure. A measurement starting section enables the measuring section to start acquisition of the measurement information in a state in which contact is maintained between the hands holding the casing and the corresponding electrocardiographic electrodes and pulse wave sensor.

15. A blood pressure measuring method, comprising:
-
detecting, by a pair of electrocardiographic electrodes respectively provided such as to allow contact with both hands of a user holding a casing, electrocardiographic signals through the hands; detects, by a pulse wave sensor provided such as to allow contact with either of the hands holding the casing, pulse wave signals through the hand; acquiring, by a measuring section, measurement information including (i) a time difference between an electrocardiographic R wave based on the electrocardiographic signals and a pulse wave reference point based on the pulse wave signals, and (ii) a pulse wave amplitude based on the pulse wave signals; calculating, by a calculating section, blood pressure using the measurement information; displaying, by a display section, the blood pressure; and enabling, by a measurement starting section, the measuring section to start acquisition of the measurement information in a state in which contact is maintained between the hands holding the casing and the corresponding electrocardiographic electrodes and pulse wave sensor.
