Abstract

An analytical magazine is proposed, which comprises a plurality of analytical aids accommodated in chambers. The analytical magazine is arranged to be accommodated in at least two orientations in an analytical system. The analytical magazine is furthermore arranged to provide the analytical system, in the orientations, in each case with a plurality of analytical aids. At least one sampling movement can be executed by means of the analytical aids. The analytical magazine is arranged to make a remagazining of the analytical aids possible.

Claims

1. An analytical magazine, wherein the analytical magazine has at least two chambers, in which analytical aids can be accommodated, wherein the analytical aids are accommodated in at least one of the chambers, wherein the analytical aids in each case comprise at least one microsampler including a lancet for making at least one opening in a test subject'"'"'s skin and at least one capillary element for transferring a body fluid having an analyte from the lancet to at least one test element, and the at least one test element with at least one test chemistry comprising an enzyme and a stable coenzyme, which are stored together, for detecting at least one analyte in a body fluid or other liquid sample, wherein the test chemistry is at least largely stable against moisture, wherein the stability is such that when stored at 32°

C., a relative humidity of the air of 85% at normal pressure for a period of three weeks an activity of the test chemistry of the analytical aid decreases by less than 50%, wherein the analytical magazine has a packing density of the analytical aids of from 5 analytical aids per cm³ to 32.3 analytical aids per cm³ and wherein humidity can be exchanged between the at least two chambers.

2. The analytical magazine according to claim 1, wherein the analytical magazine has a housing, wherein the housing has a wall thickness of not more than 1.2 mm.

3. The analytical magazine according to claim 1, wherein the analytical magazine is of drying agent-free design.

4. The analytical magazine according to claim 1, wherein the analytical magazine has a housing with at least two parts, wherein the at least two parts are joined together by a laser welding process, wherein at least one weld seam is provided with a weld seam width of max. 0.5 mm.

5. The analytical magazine according to claim 1, wherein the analytical magazine has a housing, wherein the housing has a material selected from the following materials:

a polycarbonate;

an acrylonitrile-butadiene-styrene;

a cyclo-olefin copolymer;

a polymethylmethacrylate;

a polystyrene; and

a polyethylene terephthalate.

6. The analytical magazine according to claim 1, wherein the analytical magazine is arranged to be accommodated in at least two orientations in an analytical system, wherein the analytical magazine is arranged to supply, in the orientations, in each case a plurality of analytical aids to the analytical system, wherein by means of the analytical aids at least one sampling movement can be executed, wherein the analytical aids comprise at least one transfer element for one or both of receiving a sample of a body fluid and transferring the sample, wherein the analytical magazine is arranged to make a remagazining of the analytical aids possible, wherein the analytical magazine is arranged to hold the analytical aids in place in the chambers after remagazining, wherein the analytical magazine comprises at least two essentially identical partial magazines, wherein each of the partial magazines comprises a plurality of similar analytical aids.

7. The analytical magazine according to claim 6, wherein the analytical system is provided at least partially with a symmetry.

8. The analytical magazine according to claim 6, wherein the analytical magazine comprises at least one indicating element, wherein the indicating element is designed to be detected by the analytical system and to supply at least one piece of information about a current orientation to the analytical system.

9. The analytical magazine according to claim 6, wherein the analytical magazine has a shape of a round disk, wherein the analytical aids are aligned in a radial arrangement in the analytical magazine, wherein the analytical aids are arranged in different levels of aids with an angular offset relative to one another.

10. The analytical magazine according to claim 6, wherein the analytical magazine is arranged to permit access in all orientations to one or both of a chamber located in an application position of the analytical system and at least one analytical aid accommodated in said chamber from at least two directions.

11. The analytical magazine according to claim 6, wherein the analytical aids are arranged at least partially to collect a sample of a body fluid during the sampling movement and transfer it to a test element, wherein sample transfer takes place during remagazining of the analytical aid.

12. The analytical magazine according to claim 6, wherein the analytical aids in each case comprise at least one test element with at least one test chemistry, wherein the test chemistry is arranged to change at least one detectable property when the at least one analyte is present, wherein the test chemistry is integrated at least partially in a housing of the analytical magazine.

13. The analytical magazine according to claim 8, wherein the analytical magazine comprises a number of indicating elements corresponding to the number of possible orientations.

14. The analytical magazine according to claim 10, wherein the magazine is arranged to permit the access in directions opposite to one another.

15. The analytical magazine according to claim 12, wherein the test chemistry is integrated at least partially in a wall of the chambers.

16. The analytical magazine according to claim 1, wherein the analytical magazine has a packing density of the analytical aids of from 16 analytical aids per cm³ to 32.3 analytical aids per cm³.
