Abstract

The present invention is a method and apparatus for drug sample identification, including a scale for weighing a drug sample and an imaging module for capturing digital images of the drug sample, from at least two different visual perspectives simultaneously, and an transmitting the collected data and images, via an interface, to a computer for storage and association with an image database.

Claims

1. A drug sample identification system, comprising:

an imaging staging module to enable substantially simultaneous image capturing of a first perspective view of a drug sample, a second perspective view of the drug sample, and a third perspective view of the drug sample, the first perspective view of the drug sample being different from the second perspective view of the drug sample, the first perspective view of the drug sample being different from the third perspective view of the drug sample, the second perspective view of the drug sample being different from the third perspective view of the drug sample, the first perspective view of the drug sample being orthogonal to the third perspective view of the drug sample, the second perspective view of the drug sample being orthogonal to the third perspective view of the drug sample.

2. The drug sample identification system as claimed in claim 1, further comprising:

a digital imaging device to generate a digital image of the drug sample located in said imaging staging module, said digital image representing an image of the drug sample from the first, second, and third perspective views of the drug sample.

3. The drug sample identification system as claimed in claim 1, further comprising:

a scale to weigh a drug sample.

4. The drug sample identification system as claimed in claim 2, further comprising:

an interface to enable a transmission of drug sample data including said digital image of the drug sample located in said imaging staging module to another electronic device for storage and association with a database.

5. The drug sample identification system as claimed in claim 3, further comprising:

an interface to enable a transmission of drug sample data including the weight of the drug sample and said digital image of the drug sample located in said imaging staging module to another electronic device for storage and association with a database.

6. The drug sample identification system as claimed in claim 1, further comprising:

a digital imaging mounting device to enable an external digital imaging device to be mounted so as to generate images from drug samples located in said imaging staging module.

7. The drug sample identification system as claimed in claim 1, wherein said imaging staging module comprises:

a staging device to position the drug sample for imaging;

a first reflective surface to provide the first perspective view of the drug sample positioned in said imaging staging module; and

a second reflective surface to provide the second perspective view of the drug sample positioned in said imaging staging module;

said first and second reflective surfaces being positioned to enable image capturing of the drug sample from the first, second, and third perspective views substantially simultaneously.

8. The drug sample identification system as claimed in claim 2, wherein said imaging staging module comprises:

a staging device to position the drug sample for imaging;

a first reflective surface to provide the first perspective view of the drug sample positioned in said imaging staging module; and

a second reflective surface to provide the second perspective view of the drug sample positioned in said imaging staging module;

said first and second reflective surfaces being positioned to enable image capturing of the drug sample from the first, second, and third perspective views substantially simultaneously.

9. The drug sample identification system as claimed in claim 7, wherein said staging device comprises:

a planar member to position the drug sample thereupon;

first and second backing members oriented at an angle therebetween to contact the drug sample at least two points; and

a movable member, opposed to said first and second backing members, to provide a third contact point to hold the drug sample in a fixed position on said planar member.

10. The drug sample identification system as claimed in claim 8, wherein said staging device comprises:

a planar member to position the drug sample thereupon;

first and second backing members oriented at an angle therebetween to contact the drug sample at least two points; and

a movable member, opposed to said first and second backing members, to provide a third contact point to hold the drug sample in a fixed position on said planar member.

11. The drug sample identification system as claimed in claim 7, wherein said imaging staging module further comprising:

a sliding mechanism to move said staging device from an imaging position to a loading position.

12. The drug sample identification system as claimed in claim 8, wherein said imaging staging module further comprising:

a sliding mechanism to move said staging device from an imaging position to a loading position.

13. The drug sample identification system as claimed in claim 7, wherein said staging device is rotatable such that an orientation of the drug sample may be altered by a user when the drug sample is in an imaging position.

14. The drug sample identification system as claimed in claim 8, wherein said staging device is rotatable such that an orientation of the drug sample may be altered by a user when the drug sample is in an imaging position.

15. The drug sample identification system as claimed in claim 4, wherein said interface provides hardwire communication of the drug sample data including the weight of the drug sample and said digital image of the drug sample located in said imaging staging module to another electronic device for storage and association with a database.

16. The drug sample identification system as claimed in claim 2, further comprising:

a display to provide a visualization of the imaged drug sample and to provide a visualization of known drugs from a database;

said display displaying information for a user; and

an input device to enable a user to control a functionality for the drug sample identification system and to input information related to the drug sample.

17. The drug sample identification system as claimed in claim 9, wherein said planar member including a scale device to weigh the drug sample.

18. The drug sample identification system as claimed in claim 10, wherein said planar member including a scale device to weigh the drug sample.
