Abstract

A test strip vial for storing and dispensing test strips for measuring a analyte value in a sample of bodily fluid is provided. The test strip vial comprises a hermetically sealed container configured to store a stack of test strips and dispense the test strips from the container one at a time. The test strip vial provides simplified loading of a test strip into a testing device for measuring the analyte level of a sample of bodily fluid. The test strip vial comprises an outer housing comprised of a base container and a partially attached lid for closing the base container. The vial further includes a cassette inserted in the base container for holding a supply of test strips and dispensing the test strips one-by-one from the vial using a dispensing mechanism. Biasing means is also provided for biasing the stack of test strips towards the dispensing mechanism to facilitate one-by-one dispensing. The test strip vial may further include an information chip for providing read and write storage capability to the vial.

Claims

1. A cassette for holding and dispensing test strips for analysing a sample of bodily fluid, the cassette having a dispensing opening and being configured to hold a supply of test strips, the cassette further including:

biasing means for biasing test strips held in the cassette towards the dispensing opening;

retaining means for holding the test strips in the cassette against the bias of the biasing means; and

means for moving test strips, one at a time, out of the cassette through the dispensing opening.

2. A cassette according to claim 1, wherein the biasing means is attached to the cassette.

3. A cassette according to claim 1 or claim 2, wherein the biasing means is a helical spring.

4. A cassette according to any one of the preceding claims, wherein the biasing means is connected to a strip retainer for contacting the supply of test strips.

5. A cassette according to any one of the preceding claims, wherein the retaining means is an enclosing surface at the end of the cassette having the dispensing opening therein.

6. A cassette according to claim 5, wherein the enclosing surface includes a channel in communication with the dispensing opening and configured to hold a single test strip from the supply of test strips.

7. A cassette according to claim 6, wherein the means for moving is a slider and the enclosing surface includes an elongated slot for holding the slider, such that the slider is in communication with the channel and movement of the slider towards the dispensing opening dispenses a single test strip held in the channel through the dispensing opening.

8. A cassette according to claim 7, wherein the slider is biased to return the slider to its starting position after dispensing a test strip through the dispensing opening.

9. A cassette according to any one of claims 5 to 8, further comprising a window formed in the enclosing surface to allow a user to view a number on a surface of a test strip.

10. A cassette according to any one of the preceding claims, further comprising desiccant material disposed in the cassette for preserving the test strips from humidity.

11. A cassette according to any one of the preceding claims, wherein the cassette is formed of desiccant material.

12. A cassette according to any one of the preceding claims, wherein the test strips have a length of one centimetre or less.

13. A cassette according to any one of the preceding claims, wherein the cassette is disposable.

14. A cassette according to any one of the preceding claims, wherein the bodily fluid is blood and the test strips are used for measurement of a glucose level in the blood.

15. A vial comprising a cassette according to any one of the preceding claims and an outer housing containing the cassette.

16. A vial according to claim 15 wherein the biasing means is attached to the outer housing and communicates with test strips in the cassette through a slot in the cassette.

17. A vial according to claim 15 or claim 16, wherein the outer housing is formed of desiccant material.

18. A vial according to any one of claims 15 to 17 wherein the outer housing has an oval-shaped cross-section.

19. A vial according to any one of claims 15 to 18, wherein the outer housing includes a depression to facilitate holding of the vial by a user.

20. A vial according to any one of claims 15 to 19, wherein the cassette includes a protruding portion that protrudes from the outer housing when the cassette is inserted into the outer housing and a hermetic seal is disposed on the protruding portion.

21. A vial according to any one of claims 15 to 20, wherein the outer housing comprises a lid.

22. A vial according to claim 21, wherein the outer housing includes a recessed portion adjacent to an upper rim and the lid includes a protruding portion corresponding to the recessed portion to facilitate opening or removal of the lid.

23. A vial according to any one of claims 15 to 22, further comprising data storage means carried by the vial for storing information.

24. A vial according to claim 23, wherein the data storage means is an electronic chip.

25. A vial according to claim 24, wherein the electronic chip is an EPROM or an EEPROM.

26. A vial according to any one of claims 23 to 25, wherein the information stored by the data storage means relates to information about a supply of test strips stored in the vial.

27. A vial according to claim 26, wherein the information comprises at least one of a calibration code for the supply of test strips, an expiration date of the supply of test strips, the batch code of the supply of test strips, the lot number of the supply of test strips and the number of strips in the supply of test strips.

28. A vial according to claim any one of claims 23 to 27, wherein the data storage means is adapted to store analyte values obtained by a testing device.

29. A vial according to any one of claims 23 to 28, wherein the data storage means contains software which can be transferred to a testing device.

30. A vial according to claim 29, wherein the software includes instructions for operating the testing device to accommodate a set of operating parameters for a supply of test strips stored in the vial.

31. A vial according to any one of claims 15 to 30, further comprising an adapter configured to connect to the contacts of a testing device.

32. A vial for storing and dispensing test strips for analysing a sample of bodily fluid comprising data storage means affixed to the housing for storing information related to the test strips.

33. A vial according to claim 32, wherein the data storage means is an electronic chip.
