Abstract

The invention concerns a magazine for storing test elements (1) with one or several test zones (3) which are attached adjacent to one another on a rectangular support, wherein the magazine has at least one pair of guide grooves (18a, b) located opposite to one another into which the test elements are inserted in such a way that they lie directly adjacent to one another and the edges of adjacent supports abut one another. A further subject matter of the invention is a system which comprises a slide (14, 31) in addition to the magazine according to the invention which is used to push a layer of test elements along the guide grooves towards the opposite end of the layer to remove test elements from the magazine.

Claims

1. A system for dispensing test elements, the system comprising:

(a) a magazine comprising at least two opposing guide grooves in which the test elements can be inserted such that they lie next to one another in one plane and the edges of adjacent test elements abut one another; and

(b) a slide which at one end can engage the plane formed by the test elements and move the test elements along the guide grooves towards the opposite end of the guide grooves.

2. The system of claim 1 wherein the magazine comprises a wall with at least one cut-out through which the slide can be inserted into the magazine.

3. The system of claim 1 further comprising a drive unit which can drive the slide.

4. The system of claim 3 wherein the drive unit can move the slide in one direction by an incremental distance related to the width of the test elements.

5. The system of claim 3 wherein the drive unit can control the depth of penetration of the slide into the magazine.

6. The system of claim 1 further comprising a second slide which can transport a test element which is located in a removal position from the magazine by sliding the test element in the longitudinal direction of the test element.

7. The system of claim 6 wherein the magazine comprises first and second openings in the removal position and the second slide can enter into the first opening and push a test element located in the removal position through the second opening.

8. The system of claim 1 further comprising a pivoted roller which comprises at least one groove for holding a test element.

9. The system of claim 8 wherein the roller is arranged relative to the magazine such that a test element which is pushed out of the magazine by the slide is pushed into the at least one groove of the roller.

10. The system of claim 8 wherein the magazine is located in an essentially moisture-tight housing with a cut-out and the cut-out is closed by the roller in such a way that at least one groove of the roller is located in a first position for receiving a test element within the housing and can be transported out of the housing by rotating the roller about its axis.

11. The system of claim 10 wherein the housing has a protecting part which is arranged relative to a part of the exterior peripheral surface of the roller such that a gap is formed between the roller and the protecting part which enables a test element which is located in the at least one groove and which juts out above the exterior contour of the roller to be guided through the gap by turning the roller and which forms a leakage path that limits the penetration of moisture into the housing.

12. The system of claim 8 wherein the roller comprises at least one notch which is essentially perpendicular to the longitudinal axis of the roller in the area of the at least one groove and which is deeper than the at least one groove so that a region is formed in the notch behind the groove for gripping from behind a test element located in the groove.

13. The system of claim 12 further comprising a rake which can be located outside of the housing and moved into a first position in which it engages in the notch and grips behind a test element located in the groove and which can be moved into a second position to remove the test element from the groove.

14. The system of claim 1 wherein the slide is attached via a spindle to a sliding carriage and in its resting position is in an angled position relative thereto from which it is turned away when the sliding carriage is moved and the layer of test elements offers a resistance to the slide.

15. The system of claim 14 further comprising a detection unit which can detect a rotation of the slide from its resting position.

16. The system of claim 1 further comprising a holder for an additional magazine and a lifting mechanism to lift an at least partially empty said magazine from a position for removing test elements.
