Abstract

A measurement method includes a first measurement in which a characteristic amount of a specific analyte in a biological fluid is measured with a biosensor. The method also includes a second measurement in which motion information of living activity is measured. Additionally, the method may include recording the motion information and the characteristic amount measured in the first measurement with the motion information and characteristic amount associated with each other.

First claim

What is claimed is:

1. A measurement method, comprising:
providing a measurement system that includes a measurement apparatus that has a CPU, a memory, and a motion sensor;
performing a first measurement of measuring a characteristic amount of a specific analyte in a biological fluid with a biosensor that is attached to the measurement apparatus;
performing a second measurement of measuring motion information of living activity with the motion sensor;
recording, in the memory, the motion information and the measured characteristic amount such that the motion information and the measured characteristic amount are associated with each other;
calculating, based on the motion information, living activity level in terms of METS; and
the CPU switching a mode of the measurement apparatus from one mode to another mode based upon the calculated METs,
wherein the one mode is a meal event detection processing mode in which a recorded living activity level is compared to a particular living activity level and the another mode is a living activity measurement mode in which a change amount of an output of the motion sensor is determined.

2. The measurement method according to claim 1 , further comprising displaying the motion information and the measured characteristic amount.

3. The measurement method according to claim 1 , further comprising detecting, based on the motion information and/or the measured characteristic amount, sleep duration, times of turn over or number of waking episodes.

4. The measurement method according to claim 1 , further comprising:
creating display data of a combination of the calculated living activity level and the measured characteristic amount.

5. The measurement method according to claim 1 , further comprising:
detecting, based on the motion information, sleep duration, times of turn over or number of waking episodes;
setting meal time or meal count;
selecting two or more of parameters selected from the calculated living activity level, sleep duration, times of turn over, number of waking episodes, meal time, and meal count; and
creating two-dimensional or three-dimensional display data of a combination of two or more of the parameters selected.
