Biological information measurement apparatus, biological information measurement system, biological information measurement method, and program

Abstract

The present invention provides a biological information measurement apparatus, a biological information measurement system, a biological information measurement method, and program. The biological information measurement apparatus includes a biological information acquisition unit configured to acquire at least first waveform information relating to a first waveform representing a beat of a measurement subject measured at a first measurement site, and as second waveform information relating to a second waveform representing the beat of the measurement subject measured at a second measurement site different from the first measurement site, information relating to a timing corresponding to a second feature which is a characteristic feature of the second waveform, and a pulse wave transit time calculation unit configured to, based on the first and second waveform information, calculate a pulse wave transit time, which is a difference between a timing corresponding to a first feature which is a characteristic feature of the first waveform and the timing corresponding to the second feature which is a characteristic feature of the second waveform.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of Japanese Priority Patent Application JP2012-262699 filed on Nov. 30, 2012, the entire contents of which are incorporated herein by reference. technical field [0003] The invention relates to a biological information measuring device, a biological information measuring system, a biological information measuring method and a program. Background technique [0004] In the related art, a direct measurement method is known as a method of measuring blood pressure in which the blood pressure is directly measured using air pressure. In the direct measurement method, pressure is applied to blood vessels by supplying air via an air pump into a tube (called a cuff) wrapped around an arm or the like. Blood pressure is measured by adjusting the airflow supplied to the cuff to vary the pressure on the blood vessel to determine the pressure at which blood starts and stops flowing. However, sin...

AI Technical Summary

Problems solved by technology

However, since a blood pressure monitor of a direct measurement system must have a cuff, an air pump, a detection device for detecting the start and stop of blood flow, etc., this monitor is not suitable for portable applications

Further, it is difficult to measure blood pressure at random every day due to the laborious and time-consuming measurement by the blood pressure monitor of the direct measurement system
