Abstract

Disclosed herein are an apparatus and method for measuring biomedical data and a measurement strip. The apparatus includes a plurality of detection units arranged within a strip reception area on a plane and spaced apart from each other, a measurement type determination unit for determining whether reactive portions are present in areas of the measurement strip corresponding to the plurality of detection units based on detection results obtained by the detection units and determining a type of measurement based on results of the determination, a biomedical data measurement unit for activating part or all of the detection units according to the type of measurement determined by the measurement type determination unit, and measuring the biomedical data using the activated detection units, and an output unit for outputting the measured biomedical data to an outside.

Claims

1. An apparatus for measuring biomedical data, comprising:

a plurality of detection units configured to respectively correspond to predetermined areas of a measurement strip;

a measurement type determination unit for determining whether reactive portions are present in each of the predetermined areas of the measurement strip corresponding to the plurality of detection units based on detection results obtained by the detection units and determining a type of measurement based on the presence of the reactive portion in each of the predetermined areas of the measurement strip;

a biomedical data measurement unit for activating at least one detection unit corresponding to the type of measurement determined by the measurement type determination unit among the plurality of detection units, and measuring the biomedical data using the activated detection units; and

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

2. The apparatus as set forth in claim 1, further comprising a strip insertion determination unit for determining whether the measurement strip has been inserted based on the detection results obtained by the plurality of detection units.

3. The apparatus as set forth in claim 1, wherein the output unit is a display unit for displaying the biomedical data on a screen.

4. The apparatus as set forth in claim 1, wherein each of the plurality of detection units comprises:

a light-emitting unit for emitting light toward a reactive portion of the measurement strip; and

a light-receiving unit for detecting a reflectance of the reactive portion of the measurement strip.

5. The apparatus as set forth in claim 1, wherein the type of measurement comprises measurement of an amount of total cholesterol, measurement of an amount of High Density Lipoprotein (HDL) cholesterol, and/or measurement of an amount of triglyceride.

6. A method of measuring biomedical data from the measurement strip inserted in the apparatus of claim 1, comprising:

determining whether the reactive portions are present in the predetermined areas of the measurement strip corresponding to the plurality of respective detection units of the apparatus, based on the detection results obtained by the detection units;

determining the type of measurement based on results of the determination; and

measuring the biomedical data based on the type of measurement.

7. The method as set forth in claim 6, further comprising, before determining the type of measurement, determining whether the measurement strip has been inserted based on the detection results obtained by the detection units.

8. The apparatus as set forth in claim 1, wherein the activating of at least one detection unit among the plurality of detection unit is determined by amount of light received from each detection unit.
