Abstract

The invention concerns a packaging cassette for reagent carriers, which is characterized by a base housing containing connected adjacent compartments for reagent carriers, wherein the compartments are separated from one another by partitions and are opened individually, each compartment having its own sealing cover which enables the compartment to be re-sealed.

First claim

What is claimed is:

1. Combination of a packaging cassette and reagent carriers contained therein, said reagent carriers comprising a test area with reactants immobilized thereon, and said packaging cassette comprising a one-piece base housing, the base housing having longitudinal sides, each of the longitudinal sides having a continuous guide groove extending in a longitudinal direction substantially the entire length of the base, the guide grooves are directly opposing each other and have the same structural shape, and the base is moveable via guide rails via automated loaders or automated analyzers, the base housing comprising connected adjacent side by side compartments each of which is configured to completely accommodate therein, sealingly against environmental influences, at least one reagent carrier, the compartments are separated from one another by partitions and are configured to be opened individually, each of the compartments having a respective sealing cover pivotably connected to said base housing by an individually associated hinge and configured to be separately and repeatedly resealable; said packaging cassette further comprising at least one separate desiccant reservoir adjacent said respective compartments and in communication via respective connecting holes with said compartments, said desiccant reservoir being provided in a depression impressed into a bottom of the base of the housing under said respective compartments; and wherein the desiccant reservoir is entirely formed by the impression.

2. Combination according to claim 1 , wherein said packaging cassette further comprises said desiccant reservoir containing a desiccant.

3. Combination according to claim 2 , wherein the separate desiccant reservoir is trough-shaped and sealed by a sealing foil.

4. Combination according to claim 3 , wherein the sealing covers extend into the compartments when the sealing covers are sealing the compartments.

5. Combination according to claim 1 , wherein the separate desiccant reservoir is trough-shaped and sealed by a sealing foil.

6. Combination according to claim 1 , wherein the respective sealing cover of each of the compartments and the base housing have closure elements that are assigned and complementary to one another and sealingly engage one another when each of the compartments are closed by their respective sealing cover.

7. Combination according to claim 1 , wherein each sealing cover and the base housing are manufactured interconnected as one piece.

8. Combination according to claim 1 , wherein each sealing cover and the base housing are manufactured interconnected as a one piece injection-molded product.

9. Combination according to claim 1 , wherein each sealing cover is provided with an operating tab, and wherein operating tabs of the sealing covers assigned to one row of compartments are next to one another or above one another in sequence and project beyond one edge of the base housing towards the outside in the closed state.

10. Combination according to claim 1 , further comprising a base plate in which all the compartments are in the form of depressions that are aligned relative to one another in a row.

11. Combination according to claim 1 , wherein each of the compartments is dimensioned to hold only one single reagent.

12. Combination according to claim 1 , wherein the packaging cassette is a plastic.

13. Combination according to claim 1 , wherein each of the reagent carriers comprises a trough-like depression the bottom of which forms the test area coated with the reactants.

14. Combination of a packaging cassette and reagent carriers contained therein, said reagent carriers comprising a test area with reactants immobilized thereon, and said packaging cassette comprising a one-piece base housing, the base housing having longitudinal sides, each of the longitudinal sides having a continuous guide groove extending in a longitudinal direction substantially the entire length of the base, the guide grooves are directly opposing each other and have the same structural shape, and the base is moveable via guide rails via automated loaders or automated analyzers, the base housing comprising connected adjacent side by side compartments each of which is configured to completely accommodate therein, sealingly against environmental influences, at least one reagent carrier, the compartments are separated from one another by partitions and are configured to be opened individually, each of the compartments having a respective sealing cover pivotably connected to said base housing by an individually associated hinge and configured to be separately and repeatedly resealable, said packaging cassette further comprising at least one reagent reservoir adjacent said respective compartments and being separated by a separation wall including a pre-prepared initially closed communication opening, said reagent reservoir containing a reagent; said packaging cassette further comprising at least one separate desiccant reservoir adjacent said respective compartments and in communication via respective connecting holes with said compartments, said desiccant reservoir being provided in a depression impressed into a bottom of the base of the housing under said respective compartments; and wherein the desiccant reservoir is entirely formed by the impression.

15. Combination according to claim 14 , wherein the sealing cover extends into one of the side by side compartments when the sealing cover is sealing one of the compartments.

16. Combination according to claim 15 , wherein the separate desiccant reservoir is trough-shaped and sealed by a sealing foil.

17. Combination according to claim 14 , wherein each sealing cover and the base housing are manufactured interconnected as a one piece injection-molded product.

18. Combination according to claim 14 , further comprising a base plate in which all the compartments are in the form of depressions that are aligned relative to one another in a row.

19. Combination according to claim 14 , wherein each of the compartments is dimensioned to hold only one single reagent.

20. Combination according to claim 1 , wherein each of the compartments is dimensioned to hold only one single reagent carrier and a small store of desiccant.

21. Combination according to claim 14 , wherein each of the compartments is dimensioned to hold only one single reagent carrier and a small store of desiccant.
