Portable device for measuring blood pressure and method therefor

摘要

A portable blood pressure measuring apparatus and a method therefor are provided. In the portable blood pressure measuring apparatus, a blood pressure measurer measures a wrist or finger blood pressure being an arterial pressure at a wrist or a finger, a Pulse Wave Velocity (PWV) measurer measures a PWV, a controller controls compensation of the wrist or finger blood pressure using the PWV so that the wrist or finger blood pressure corresponds to a brachial blood pressure, and a display displays the compensated wrist or finger blood pressure.

1. A portable blood pressure measuring apparatus comprising:
a blood pressure measurer for measuring a wrist or finger blood pressure, wherein the wrist or finger blood pressure is an arterial pressure measured at a wrist or a finger; a Pulse Wave Velocity (PWV) measurer for measuring a PWV; a controller for controlling compensation of the wrist or finger blood pressure using the measured PWV so that the wrist or finger blood pressure corresponds to a brachial blood pressure; and a display for displaying the compensated wrist or finger blood pressure, wherein the controller controls the compensation of the wrist or finger blood pressure using one of the following equations:
Pbrachial=a+b×Pwrist or finger+c×PWVPbrachial=a+b×Pwrist or finger+c×PWV+d×PWV2 Pbrachial=a+b×Pwrist or finger+c×PWV+d×PWV2+e×PWV3 where Pbrachial is a brachial blood pressure Pwrist or finger is a blood pressure measured at the wrist or finger, PWV is a PWV, and a, b, c, d and e are empirical constants for compensating the wrist or finger blood pressure value.
