PORTABLE BLOOD PRESSURE MEASURING APPARATUS AND BLOOD PRESSURE MEASURING METHOD IN PORTABLE TERMINAL
First Claim
1. A portable blood pressure measuring apparatus, the apparatus comprising:
- an electrocardiogram electrode unit, including a first electrode, a second electrode, and a third electrode included in a surface of a body, which measure an electrocardiogram signal through the first electrode through the third electrode;
a first sensor unit which measures a pulse wave signal;
a second sensor unit which senses a movement of the portable blood pressure measuring apparatus;
a controller which determines whether the movement is sensed by the second sensor unit during measuring the electrocardiogram signal and the pulse wave signal, and which performs controlling so as to measure the electrocardiogram signal and the pulse wave signal when it is sensed that the movement is less than a threshold value; and
a wireless communication unit which transmits the measured electrocardiogram signal and pulse wave signal to a portable terminal that measures a blood pressure value using the measure electrocardiogram signal and the pulse wave signal.

Abstract
A method and apparatus for readily measuring a blood pressure without using a cuff includes measuring, by a portable blood pressure measuring apparatus, an electrocardiogram signal and a pulse wave signal, transmitting the measured electrocardiogram signal and pulse wave signal to a portable terminal, calculating, by the portable terminal, a Pulse Transit Time (PTT) and a Pulse Wave Velocity (PWV) using the transmitted electrocardiogram signal and the pulse wave signal, and calculating a blood pressure value based on the PTT and the PWV. Therefore, users may readily measure a blood pressure at any time and place and may be provided with a customized blood pressure measurement result.
