Abstract

In a biological information processing apparatus, a body motion detection unit detects a body motion of a subject. A measurement method selection unit selects one measurement method on the basis of a detection result from the body motion detection unit, from among a plurality of measurement methods of measuring a blood glucose level by applying irradiation waves toward a living body of the subject. A measurement result display control unit performs control for displaying a measurement result which is obtained by performing a measurement according to the one measurement method.

Claims

1. A biological information processing apparatus comprising:

a body motion detection unit that detects a motion of a body of a subject;

a selection unit that selects one measurement method based upon a result of the detection by the body motion detection unit, the one measurement method being selected from among a plurality of measurement methods of measuring a blood component by applying irradiation waves toward the body of the subject; and

a display control unit that performs control for displaying a measurement result obtained by performing a measurement according to the one measurement method.

2. The biological information processing apparatus according to claim 1, further comprising:

a parameter setting unit that sets a measurement parameter related to the one measurement method based upon the detection result.

3. The biological information processing apparatus according to claim 2, wherein the parameter setting unit sets (1) at least one of a number of measurement points, and (2) a measurement time corresponding to a duration in which the irradiation waves are applied, as the measurement parameter.

4. The biological information processing apparatus according to claim 1, wherein the plurality of measurement methods are different from each other and depend on measurement object sites.

5. The biological information processing apparatus according to claim 4, wherein, when the detection result satisfies a condition indicating that a level of the body motion is low, the selection unit selects one measurement method in which a blood vessel portion is set as the measurement object site.

6. The biological information processing apparatus according to claim 4, wherein, when the detection result satisfies a condition indicating that a level of the body motion is high, the selection unit selects one measurement method in which a non-blood vessel portion other than a blood vessel is set as the measurement object site.

7. The biological information processing apparatus according to claim 1, further comprising:

a measurement unit that measures the blood component by using the plurality of measurement methods together,

wherein the display control unit displays a measurement result that is obtained by performing a measurement according to the one measurement method among measurement results from the measurement unit.

8. The biological information processing apparatus according to claim 1, wherein the measurement methods are a plurality of methods for measuring a blood glucose level.

9. A biological information processing method comprising:

detecting a motion of a body of a subject;

selecting one measurement method based upon a result of the detection, the one measurement method being selected from among a plurality of measurement methods of measuring a blood component by applying irradiation waves toward the body of the subject; and

performing control for displaying a measurement result obtained by performing a measurement according to the one measurement method.

10. A biological information processing apparatus comprising:

a wearable sensor adapted to detect a characteristic of a subject;

a processor configured to execute a step of selecting a measurement method for measuring a blood component based upon the detected characteristic, and a step of measuring the blood component using the selected measurement method,

wherein the measurement method is selected from among a plurality of measurement methods that measure the blood component by using irradiation waves; and

a display that displays a result of a measurement obtained by the processor.
