Abstract

The present invention relates to a method for obtaining information from a medication package. In the method, an image of the medication package is provided, the image is analyzed to determine positions and formats of patterns in the image, a layout, which has similar pattern formats in the same positions as the image, is selected from a set of layouts stored in the medication dispenser, the selected layout defining the type of information for each pattern in the image, and the information contained in at least one of the patterns of the image is interpreted by linking the content of the pattern to the type of information defined in the selected layout. The invention also relates to a medication dispenser.

Claims

1. A method for a medication dispenser to obtain information from a medication package, comprising:

providing an image of the medication package;

wherein the method comprises;

analysing the image to determine positions and formats of patterns in the image,

selecting a layout, which has similar pattern formats in the same positions as the image, from a set of layouts stored in the medication dispenser, the selected layout defining the type of information for each pattern in the image, and

interpreting the information contained in at least one of the patterns of the image by linking the content of the pattern to the type of information defined in the selected layout.

2. The method according to claim 1, wherein the step of providing an image of the medication package comprises:

capturing with a camera at least one image of the medication package, and

combining the at least one image into a single image.

3. The method according to claim 2, wherein the method comprises moving the medication package across an imaging area of the camera between the capturing of the images.

4. The method according to claim 2, wherein the method comprises illuminating with at least one light source the medication package.

5. The method according to claim 4, wherein the method comprises changing the intensity and/or the direction and/or the wavelength of the lighting.

6. The method according to 2, wherein the method comprises changing the position of the camera.

7. The method according to claim 1, wherein the step of providing an image of the medication package comprises receiving the image from a server over a communications network.

8. The method according to claim 1, wherein, if an error occurs in the step of selecting a layout, the method comprises:

sending the image to a server over a communications network,

generating, at the server, a new layout based on the image, and

sending the new layout to the medication dispenser over a communications network.

9. The method according to claim 1, wherein one or more of the steps of analysing the image, selecting a layout and interpreting the information are carried out at a server that is communicatively connected to the medication dispenser over a communications network.

10. A medication dispenser, comprising:

a container for holding a medication package containing medications to be taken at a predetermined taking time,

means for transferring the medication package from the container to an outlet of the medication dispenser, and

means for providing an image of the medication package;

wherein the medication dispenser comprises a control unit that comprises;

means for analysing the image to determine positions and formats of patterns in the image,

means for maintaining a set of layouts in the medication dispenser,

means for selecting a layout, which has similar pattern formats in the same positions as the image, from the set of layouts, the selected layout defining the type of information for each pattern in the image, and

means for interpreting the information contained in at least one of the patterns of the image by linking the content of the pattern to the type of information defined in the selected layout.

11. The medication dispenser according to claim 10, wherein the means for providing an image of the medication package comprises a camera.

12. The medication dispenser according to claim 11, wherein the medication dispenser comprises at least one light source arranged to illuminate the medication package.

13. The medication dispenser according to claim 10, wherein the means for providing an image of the medication package comprises a communications unit for receiving the image from a server over a communications network.

14. The medication dispenser according to claim 10, wherein the medication dispenser comprises a detector arranged to detect the presence of the medication package in the container.

15. A method for a medication dispenser to obtain information from a medication package, comprising:

obtaining an image of the medication package, the image of the medication package including at least two different patterns;

analyzing the image of the medication package to determine both a format of each of the two patterns in the image of the medication package and a position of each pattern in the image of the medication package, the format of one of the patterns in the image of the medication package being a barcode and the format of the other pattern in the image of the medication package being text;

selecting a layout from a set of layouts stored in the medication dispenser based on the image of the medication package, the selected layout having similar formats in the same corresponding positions as the formats in the image of the medication package, the selected layout defining the type of information for each pattern in the image of the medication package; and

interpreting the information contained in at least one of the patterns of the image of the medication package by linking the content of the pattern to the type of information defined in the selected layout.

16. The method according to claim 15, wherein the barcode and the text are horizontally spaced apart from one another in a width direction of the image of the medication package.

17. The method according to claim 15, wherein the medication package includes perforations at a top edge and a bottom edge of the medication package, and one of the at least two patterns is positioned adjacent the top edge of the medication package and the other of the at least two patterns is positioned adjacent the bottom edge of the medication package.
