Abstract

The invention relates to a magazine for a device of a measuring system for determining an analyte concentration in a body fluid sample, wherein the magazine contains consumable analytical elements in a plurality of chambers. According to the invention, a data carrier, on which information is stored, is fastened to the magazine, the information indicating which magazine chambers are not intended for removal of a consumable element due to manufacturing defects. The invention further relates to a device, the control unit of which suppresses access by the removal unit to predefined magazine chambers, to a measuring system comprising such a device and a magazine, and to a method for controlling the removal unit of the device.

Claims

1-15. -15. (canceled)

16. A magazine for a device of a measuring system for determining an analyte concentration in a body fluid sample, the magazine containing consumable analytical elements in a plurality of chambers, wherein the consumable elements are lancets and/or test elements wherein a data carrier, on which information is stored, is fastened to the magazine, the information indicating which magazine chambers are not intended for removal of a consumable element due to manufacturing defects.

17. The magazine according to claim 16, wherein the data carrier is an electronic memory.

18. The magazine according to claim 16, wherein the data carrier is an RFID chip.

19. The magazine according to claim 16, wherein the magazine chambers that are not intended for removal of a consumable element due to manufacturing defects are closed by a film as are the magazine chambers that are intended for removal of a consumable element.

20. The magazine according to claim 16, wherein each of the magazine chambers contains no more than one consumable analytical element.

28. A method for controlling a removal unit of a device of a measuring system, the unit being used to remove consumable analytical elements from chambers of a magazine that is inserted in the device, the magazine being moved incrementally in the device so that the magazine chambers consecutively arrive in a removal position in which the removal unit can access the respective chamber and remove an consumable element, wherein

a data carrier is read, which is fastened to a magazine containing consumable analytical elements in magazine chambers,

information stored on the data carrier is evaluated, the information indicating which magazine chambers are not intended for removal of an consumable element due to manufacturing defects, and

the magazine is advanced by one increment and the next chamber is brought into the removal position before the removal unit gains access, as soon as a magazine chamber that is not intended for removal of an consumable element due to manufacturing defects is in the removal position.

29. A measuring system for determining an analyte concentration of a body fluid sample, comprising

a magazine containing consumable analytical elements in a plurality of chambers and

a device in which the magazine can be inserted and which comprises a removal unit for removing the consumable elements from the magazine chambers and a control unit,

wherein the control unit suppresses access by the removal unit to chambers of a magazine as soon as a predefined maximum number of consumable elements has been removed from the magazine, said predefined maximum number being a variable, which is reset to a default value after a new magazine is inserted.
