Abstract

An injection amount measuring apparatus for a syringe indicated with injection amount absolute value information is provided. The injection amount measuring apparatus includes an injection amount absolute value information extracting unit configured to extract the injection amount absolute value information; a control unit configured to analyze the extracted injection amount absolute value information to determine injection amount information for an injection amount to be injected from the syringe; and a storage unit configured to store the injection amount information.

Claims

1. An injection amount measuring apparatus for a syringe indicated with injection amount absolute value information, the apparatus comprising:

an injection amount absolute value information extracting unit configured to extract the injection amount absolute value information;

a control unit configured to analyze the extracted injection amount absolute value information to determine injection amount information for an injection amount to be injected from the syringe; and

a storage unit configured to store the injection amount information,

wherein the injection amount absolute value information extracting unit captures an image of the injection amount absolute value information, and the control unit recognizes the injection amount based on the captured injection amount absolute value information using Optical Character Recognition (OCR) technology.

2. The apparatus of claim 1, wherein the injection amount absolute value information includes at least one of a number corresponding to the injection amount and a pattern preset to correspond to the injection amount.

3. The apparatus of claim 2, wherein when the control unit recognizes the number corresponding to the injection amount, the number is segmented, and the segmented number is normalized and recognized, according to the OCR technology.

4. The apparatus of claim 2, wherein the pattern includes at least one grid.

5. The apparatus of claim 4, wherein when the control unit recognizes the pattern corresponding to the injection amount, the control unit differentiates indicated grids and non-indicated grids among grids in the pattern, and analyzes the coordinates of the indicated grids to recognize the injection amount absolute value.

6. The apparatus of claim 1, wherein the control unit performs a control such that the time of injection by the syringe is stored in the storage unit.

7. The apparatus of claim 1, wherein the control unit performs a control such that the injection amount information is measured plural times, and cumulative injection amount information is calculated and stored in the storage unit.

8. The apparatus of claim 1, further comprising:

a display unit for displaying the injection amount information.

9. The apparatus of claim 1, further comprising:

an opening, into which the syringe is introduced, such that the syringe is attached to the injection amount measuring apparatus.
