Abstract

A biological information analyzing device includes: an indicator extraction unit that extracts an indicator pertaining to a characteristic of a blood pressure waveform using data of the blood pressure waveform obtained by a sensor, which is worn on a user's body and can non-invasively measure the blood pressure waveform for each of heartbeats, continuously measuring the blood pressure waveform; and a processing unit that carries out a process based on the extracted indicator.

First claim

The invention claimed is:

1. A biological information analyzing system comprising:
a compression mechanism comprising an air bladder and a fluid pump, the compression mechanism being configured to supply force against a body of a user;
a sensor adapted to be worn on the body of the user, the sensor being configured to non-invasively measure a blood pressure waveform for each heartbeat by continuously measuring the blood pressure waveform;
at least one processor configured to operate as:
an indicator extraction unit configured to extract an indicator pertaining to a characteristic of the blood pressure waveform using data of the blood pressure waveform obtained by the sensor; and
a processing unit configured to carry out a process based on the extracted indicator;
wherein the indicator extraction unit is configured to extract the indicator based upon a ratio between a pulse wave interval and a pulse pressure in the blood pressure waveform for a single heartbeat; and
wherein the processing unit is configured to output information indicating that a pulse of the user is abnormal when a value of the extracted indicator equals or exceeds a value indicating an occurrence of an abnormality, and

an output screen configured to display the output information, thereby notifying the user of the abnormal pulse,
wherein the sensor is configured to measure the blood pressure waveform in real time, and the processor is configured to extract the indicator and output the information in real time.

2. The biological information analyzing system according to claim 1 , wherein the characteristic of the blood pressure waveform includes a characteristic of a shape of the blood pressure waveform for a single heartbeat.

3. The biological information analyzing system according to claim 1 , wherein the characteristic of the blood pressure waveform includes a change in the blood pressure waveform over time.

4. The biological information analyzing system according to claim 1 , wherein the characteristic of the blood pressure waveform includes a frequency component of the blood pressure waveform.

5. The biological information analyzing system according to claim 1 , wherein the characteristic of the blood pressure waveform includes a statistical characteristic of the blood pressure waveform in a set section.

6. The biological information analyzing system according to claim 1 , wherein the indicator extraction unit extracts an indicator pertaining to respiratory and/or circulatory function based upon at least one of: a characteristic of a shape of the blood pressure waveform for a single heartbeat, a change in the blood pressure waveform over time, a frequency component of the blood pressure waveform, and a statistical characteristic of the blood pressure waveform in a set section.

7. A non-transitory computer-readable medium storing a program causing a processor to function as the indicator extraction unit and the processing unit of the biological information analyzing system according to claim 1 .

8. A biological information analyzing method comprising:
a step of supplying force against a body of a user;
a step of non-invasively measuring a blood pressure waveform of each heartbeat of the body of the user with a sensor adapted to be worn on the body of the user;
a step of extracting an indicator pertaining to a characteristic of the blood pressure waveform using data of the blood pressure waveform obtained by the sensor;
wherein extracting the indicator comprises extracting the indicator based upon a ratio between a pulse wave interval and a pulse pressure in the blood pressure waveform for a single heartbeat, and
a step of carrying out a process based on the extracted indicator;
a step of outputting information indicating that a pulse of the user is abnormal when a value of the extracted indicator equals or exceeds a value indicating an occurrence of an abnormality; and
a step of displaying the output information to the user, thereby notifying the user of the abnormal pulse
wherein the steps of measuring the blood pressure waveform, extracting the indicator, and outputting the information occur in real time.
