Abstract

The present invention relates to a measurement error correction device of a bio-measurer and, more specifically, provides a measurement correction device which: enables a device for measuring a measurement error to be arranged inside a bio-measurer such that a measurement error can be corrected after the bio-measurer is manufactured; and enables a user to directly confirm, automatically or by the user'"'"'s selection, whether the bio-measurer is normally operated at an early stage of the operation of the bio-measurer, thereby reducing the time and the cost for correcting a measurement error during a manufacturing process of the bio-measurer.

Claims

1. A measurement error correction device of a bio-measurer, the device comprising:

a first simulator having a first resistance value;

a second simulator having a second resistance value;

a measurement section measuring a first current value by applying electric power to the first simulator and measuring a second current value by applying electric power to the second simulator; and

a correction section correcting a measurement error of the bio-measurer using the first current value and the second current value.

2. The measurement error correction device according to claim 1, wherein the correction section corrects the measurement error of the bio-measurer by measuring the first current value and the second current value in an error correction mode in which an error of the bio-measurer is corrected.

3. The measurement error correction device according to claim 2, wherein the correction section calculates a correction slope and a correction size from the measured first current value, the measured second current value, a first theoretical current value corresponding to the first resistance value and applied electric power, and a second theoretical current value corresponding to the second resistance value and applied electric power.

4. The measurement error correction device according to claim 3, further comprising:

a third simulator having a third resistance value; and

an operation inspection section measuring a third current value by applying electric power to the third simulator and inspecting whether or not the bio-measurer ordinarily operates based on the third current value in a user mode in which it is inspected whether or not the bio-measurer ordinarily operate.

5. The measurement error correction device according to claim 4, wherein the first simulator, the second simulator, the measurement section, the correction section, and the third simulator of the measurement error correction device are disposed within the bio-measurer.

6. The measurement error correction device according to claim 5, wherein the operation inspection section determines whether or not the bio-measurer ordinarily operates based on whether or not the third current value is in a threshold current range.

7. The measurement error correction device according to claim 5, wherein the third resistance value of the third simulator is greater than the first resistance value and smaller than the second resistance value.

8. The measurement error correction device according to claim 5, further comprising a mode control section selecting the error correction mode and the user mode, wherein the correction section operates in the error correction mode and the operation inspection section operates in the user mode.

9. The measurement error correction device according to claim 8, wherein the mode control section performs operation control in the error correction mode when electric power is initially applied to the bio-measurer after the bio-measurer is fabricated and performs operation control in the user mode when the bio-measurer is turned on after the measurement error of the bio-measurer is corrected in the error correction mode.

10. The measurement error correction device according to claim 9, wherein the operation inspection section outputs an abnormality message to a user when the bio-measurer abnormally operates in the user mode.
