Abstract
An acetone concentration estimate device acquires a measured acetone concentration measuring acetone excreted from a user, acquires an elapsed time which has elapsed since the user ate a meal, and estimates an acetone concentration, which is a ketone body concentration of when an amount of change in blood sugar level of the user per given unit of time is stable, based on the acquired current measured acetone concentration and on the acquired elapsed time, and outputs information corresponding to the estimated acetone concentration.
Claims19
A device comprising:
- processing circuitry configured to perform a process, the process including:
- detecting, using a sensor device at a current point in time, a current measurement of ketone body concentration measuring ketone bodies excreted from a user, wherein the current measurement of ketone body concentration represents a post-meal ketone body concentration after the user ate a meal;
- detecting an elapsed time since the user ate a meal, the elapsed time being a time period from a point in time when the user ate a meal to the current point in time;
- detecting at least one user-specific parameter including at least one of a carbohydrate intake amount, a basal metabolic rate and an active energy expenditure of the user;
- determining a ketone body concentration correction amount using the elapsed time and the at least one user-specific parameter;
- estimating a stable ketone body concentration based on the current measured ketone body concentration and the ketone body concentration correction amount, wherein the stable ketone body concentration represents a pre-meal ketone body concentration of when an amount of change in blood sugar level of the user per given unit of time is stable;
- and
- outputting information corresponding to the stable ketone body concentration.

A detection method comprising:
- detecting, using a sensor device at a current point in time, a current measurement of ketone body concentration measuring ketone bodies excreted from a user, wherein the current measurement of ketone body concentration represents a post-meal ketone body concentration after the user ate a meal;
- detecting an elapsed time since the user ate a meal, the elapsed time being a time period from a point in time when the user ate a meal to the current point in time;

- determining a ketone body concentration correction amount using the elapsed time and the at least one user-specific parameter;
- estimating a stable ketone body concentration based on the current measured ketone body concentration and the ketone body concentration correction amount, wherein the stable ketone body concentration represents a pre-meal ketone body concentration of when an amount of change in blood sugar level of the user per given unit of time is stable;
- and
- outputting information corresponding to the stable ketone body concentration.
