Abstract

A method for producing an analytical magazine is proposed. The analytical magazine is designed to receive a plurality of analytical aids in a plurality of chambers. The method comprises the following steps: providing at least one first component of the analytical magazine, wherein the first component comprises a plurality of receptacles; providing a plurality of analytical aids, wherein the analytical aids are connected to one another and preferably oriented with respect to one another by at least one holding element; introducing the analytical aids into the receptacles; and separating the analytical aids from the holding element.

First claim

What is claimed is:

1. An analytical magazine comprising a plurality of analytical aids received in chambers, wherein the analytical magazine has at least one test chemical which is designed to change at least one measurable property in the presence of at least one analyte to be detected, wherein the at least one test chemical is applied to a continuous carrier and forms at least one test chemical field, wherein the test chemical field is an area coated with test chemical throughout and is provided jointly for a plurality of the chambers, wherein in each case at least one region of the test chemical field faces the interiors of the chambers and is accessible from inside the chambers, wherein the analytical magazine is made by a method comprising;
providing at least one first component of the analytical magazine, wherein the first component comprises a plurality of receptacles,
providing a plurality of analytical aids, wherein the analytical aids are connected to one another by means of at least one holding element,
introducing the analytical aids into the receptacles, wherein a plurality of the chambers are loaded simultaneously; and
separating the analytical aids from the holding element, and wherein the analytical aids are produced at least in part integrally with the holding element, wherein the analytical aids comprise lancets, micro-samplers, or lancets and micro-samplers,
wherein the analytical aids are worked from a basic material of the holding element, such that the holding element and the analytical aids or parts thereof are produced, wherein the basic material is a metallic basic material,
wherein the analytical magazine further comprises a housing with at least two components, wherein a first of the at least two components and a second of the at least two components have a different transparency, and wherein the at least two components have different absorptions in a spectral range of 700 to 1100 nm.

2. The analytical magazine according to claim 1 wherein the test chemical field is part of the housing.

3. The analytical magazine according to claim 1 , wherein the housing comprises a material selected from the following materials: a polycarbonate; an acrylonitrile-butadiene-styrene; a cycloolefin copolymer; a polymethyl methacrylate; a polystyrene; and a polyethylene terephthalate.

4. The analytical magazine according to claim 1 , wherein the analytical aids furthermore have at least one lancet with at least one capillary channel for receiving body fluid, which is conducted to the test chemical via the lancet.

5. The analytical magazine according to claim 4 , wherein the capillary channel of the lancet is coated in order to enable improved transport of the body fluid.

6. The analytical magazine according to claim 2 , wherein the test chemical field is part of an outer magazine housing wall.

7. The analytical magazine according to claim 1 , wherein the analytical aids are arranged in a circular pattern such that tips of the analytical aids point radially outward from a center of the circular pattern.

8. The analytical magazine according to claim 1 , wherein the analytical aids are mounted such that they are movable for a sampling movement.

9. An analytical magazine comprising a plurality of analytical aids received in chambers, wherein the analytical magazine has at least one test chemical which is designed to change at least one measurable property in the presence of at least one analyte to be detected, wherein the at least one test chemical is applied to a continuous carrier and forms at least one test chemical field, wherein the test chemical field is an area coated with test chemical throughout and is provided jointly for a plurality of the chambers, wherein in each case at least one region of the test chemical field faces the interiors of the chambers and is accessible from inside the chambers, wherein the analytical magazine has a housing with at least two components which are connected to one another by at laser welding seams having, widths of at most 0.3 mm.

10. The analytical magazine according to claim 9 , wherein the test chemical field is part of the housing.

11. The analytical magazine according to claim 10 , wherein the test chemical field is part of an outer magazine housing wall.

12. The analytical magazine according to claim 9 , wherein the analytical aids comprise lancets, micro-samplers, or lancets and micro-samplers.

13. The analytical magazine according to claim 9 , wherein the analytical aids are mounted such that they are movable for a sampling movement.

14. The analytical magazine according to claim 9 , wherein the analytical aids are arranged in a circular pattern such that tips of the analytical aids point radially outward from a center of the circular pattern.
