Abstract

It is an object of certain embodiments of the present invention to suppress variance in measurement results from a biological information measurement device and enhance measurement accuracy. A biological information measurement device comprises a main case having a sensor mounting component for mounting a sensor that senses biological information, a measurement component that connects to the sensor mounting component, a controller that connects to the measurement component, a first timer that connects to the controller, and a second timer that connects to the controller. The controller has a measurement mode in which a measurement operation is performed through the measurement component. In the measurement mode, the controller executes the measurement operation based on a preset measurement timing using the first timer, and determines the suitability of the measurement operation based on the preset measurement timing, using the second timer.

Claims

1. A biological information measurement device, comprising:

a main case including a sensor mounting component configured to mount a sensor that senses biological information;

a measurement component that connects to the sensor mounting component;

a controller that connects to the measurement component;

a first timer that connects to the controller; and

a second timer that connects to the controller,

wherein the controller has a measurement mode in which a measurement operation is performed through the measurement component, and

in the measurement mode, the controller executes the measurement operation based on a preset measurement timing using the first timer, and uses the second timer to determine a suitability of the measurement operation based on the preset measurement timing.

2. The biological information measurement device according to claim 1,

wherein in the measurement mode the controller determines whether or not there is a discrepancy between the preset measurement timing and an actual measurement timing of the measurement component.

3. The biological information measurement device according to claim 2,

further comprising a display component that connects to the controller,

wherein the controller causes the display component to display information indicating whether or not there is a discrepancy between the preset measurement timing and the actual measurement timing.

4. The biological information measurement device according to claim 1,

wherein the second timer is actuated by the controller before the measurement operation is performed through the measurement component.

5. The biological information measurement device according to claim 1,

wherein the second timer is constituted by a ceramic oscillator.

6. The biological information measurement device according to claim 5,

wherein the second timer is provided integrally inside the controller.

7. The biological information measurement device according to claim 1,

wherein the controller:

executes the measurement operation at a plurality of preset measurement timings in the measurement mode, and

uses the second timer to determine the suitability of each measurement operation based on the plurality of preset measurement timings.

8. The biological information measurement device according to claim 7,

wherein in the measurement mode the controller determines whether or not there is a discrepancy between one or more preset measurement timings out of the plurality of preset measurement timings and a corresponding actual measurement timing when the measurement operation is executed on the basis of said one or more preset measurement timings.

9. A biological information measurement device, comprising:

a main case;

a sensor mounting component configured to mount a sensor that senses biological information;

a measurement component that connects to the sensor mounting component and measures the biological information;

a controller that connects to the measurement component and causes the measurement component to measure the biological information;

a first timer that connects to the controller and acquires at least one preset first measurement timing at which the measurement component measures the biological information; and

a second timer that connects to the controller and acquires a second measurement timing at which the measurement component measures the biological information on the basis of the first measurement timing,

wherein the controller;

determines a discrepancy between the preset first measurement timing and the second measurement timing, and

completes the measurement of the biological information by the measurement component only when the discrepancy is within a specific range.

10. The biological information measurement device according to claim 9, wherein the first timer and the second timer operate independently.

11. The biological information measurement device according to claim 9,

wherein the controller executes a measurement mode for causing the measurement component to measure, and

the second timer is actuated after the measurement mode is started.

12. The biological information measurement device according to claim 9, wherein the controller outputs error information when the discrepancy exceeds the specific range.

13. The biological information measurement device according to claim 9,

wherein the preset first measurement timing and the second measurement timing each consist of a plurality of measurement timings, and

the controller determines the discrepancy between each preset first measurement timing and each corresponding second measurement timing, and completes the measurement of the biological information by the measurement component only when all of the discrepancies are within the specific range.

14. The biological information measurement device according to claim 9, wherein the controller outputs a result of the biological information measurement only when the discrepancy is within the specific range.
