Abstract

Disclosed herein is a method and apparatus for measuring biomedical data. The method of measuring biomedical data using a biochemical reaction includes determining reaction termination time at which the biochemical reaction has been stabilized based on an average variation in a predetermined period in an early stage of measurement, and obtaining a final measured value by adding a correction value to a value measured at the determined reaction termination time.

Claims

1. A method of measuring biomedical data in an apparatus for measuring biomedical data using a biochemical reaction, comprising:

determining reaction termination time at which the biochemical reaction has been stabilized based on an average variation in a predetermined period in an early stage of measurement; and

obtaining a final measured value by adding a correction value to a value measured at the determined reaction termination time.

2. The method as set forth in claim 1, wherein the biochemical reaction is an enzyme reaction.

3. The method as set forth in claim 1, wherein the reaction termination time is a point of time at which a current average variation is a value which is equal to or less than a value obtained by multiplying the average variation in the predetermined interval in the early stage of measurement by a determination constant.

4. The method as set forth in claim 3, wherein the determination constant is in a range from 0.001 to 0.5.

5. The method as set forth in claim 1, wherein the correction value is a difference between a measured value at a start of the predetermined interval in the early stage of measurement and a measured value at an end of the predetermined interval in the early stage of measurement.

6. The method as set forth in claim 1, wherein the predetermined interval in an early stage of measure is determined depending on the type of measurement.

7. An apparatus for receiving a measurement strip and measuring biomedical data using the measurement strip, comprising:

one or more detection units arranged within an strip reception area on one plane;

a correction data generation unit for generating correction data based on data detected by the detection unit;

a reaction termination time determination unit for determining reaction termination time based on the data detected by the detection unit;

a biomedical data measurement unit for measuring biomedical data, based on the data detected by the detection unit at the determined reaction termination time and the generated correction data; and

an output unit for outputting the biomedical data to an outside.

8. The apparatus as set forth in claim 7, wherein the apparatus for measuring biomedical data is an apparatus for measuring cholesterol.

9. The apparatus as set forth in claim 7, wherein the reaction termination time determination unit determines the reaction termination time to be a point of time at which a current average variation is a value which is equal to or less than a value obtained by multiplying an average variation in the predetermined interval in the early stage of measurement by a determination constant.

10. The apparatus as set forth in claim 7, wherein the correction data generation unit determines the correction value to be a difference between a measured value at a start of the predetermined interval in the early stage of measurement and a measured value at an end of the predetermined interval in the early stage of measurement.

11. The apparatus as set forth in claim 9, wherein the predetermined interval in an early stage of measure is determined depending on the type of measurement.

12. The apparatus as set forth in claim 10, wherein the predetermined interval in an early stage of measure is determined depending on the type of measurement.
