Abstract

A blood glucose level measurement apparatus is a non-invasive measurement apparatus mounted on a wrist or the like of a user and using light, and intermittently measures a blood glucose level of the user. A measurement interval is set according to a measured blood glucose level. For example, in a case where the measured blood glucose level is low, the measurement interval is set to be short.

Claims

1. A blood glucose level measurement apparatus comprising:

a measurement unit that repeatedly measures a blood glucose level of a user; and

a measurement interval setting unit that sets a measurement interval between the measurements performed by the measurement unit on the basis of a measurement result from the measurement unit.

2. The blood glucose level measurement apparatus according to claim 1, wherein the measurement interval setting unit sets a first measurement interval when the measurement result is in a first range, and sets a second measurement interval shorter than the first measurement interval when the measurement result is in a second range shorter than the first range.

3. The blood glucose level measurement apparatus according to claim 1, further comprising:

a storage unit that stores the measurement result,

wherein the measurement interval setting unit includes a prediction portion that predicts a blood glucose level by using the measurement result stored in the storage unit, and sets the measurement interval by using a prediction result.

4. The blood glucose level measurement apparatus according to claim 3, wherein the measurement interval setting unit includes a determination portion that determines a point of time at which the prediction result satisfies a predetermined condition, and sets the measurement interval so that the measurement unit performs the next measurement at the point of time.

5. The blood glucose level measurement apparatus according to claim 3, further comprising:

an acquisition unit that acquires a scheduled action of the user,

wherein the measurement interval setting unit includes a prediction result adjustment portion that adjusts the prediction result on the basis of the scheduled action.

6. The blood glucose level measurement apparatus according to claim 5, wherein the prediction result adjustment portion adjusts and reduces a predicted value of a blood glucose level included in the prediction result when the scheduled action is an action related to exercise or insulin administration.

7. The blood glucose level measurement apparatus according to claim 5, wherein the prediction result adjustment portion adjusts and increases a predicted value of a blood glucose level included in the prediction result when the scheduled action is an action related to a meal.

8. A blood glucose level measurement method comprising:

repeatedly performing measurements of a blood glucose level of a user; and

setting an interval between the measurements on the basis of a result of the measurement.

9. A blood glucose level measurement apparatus comprising:

a measurement unit that repeatedly measures a blood glucose level of a user;

an acquisition unit that acquires a scheduled action of the user; and

a measurement interval setting unit that sets a measurement interval between the measurements performed by the measurement unit on the basis of a measurement result from the measurement unit and a type of the scheduled action of the user.
