Abstract

A system and method for measuring substance concentrations is provided. The system has a test strip container for receiving a test strip(s). The container has a sealing device, a counter device that counts a number of opening processes of the sealing device, a data carrier that stores batch-specific data of the test strip(s), a data transmission device for wireless transmission of the data and of the number. An analysis module has a device for measuring substance concentrations by the test strip(s), and a data-receiving device for wireless reception of the data from the data transmission device and of the number. The method records the number and stores the number on the data carrier; sends data and the number by wireless transmission to the analysis module, and determines a substance concentration by the test strip(s). Also or instead, the counter device counts a time duration of the opening processes.

Claims

1. A portable analytical measurement system for measuring substance concentrations in a liquid media, the system comprising:

a) a test strip container for receiving at least one test strip, said test strip container including

a sealing device,

a counter device for counting a number of opening processes of the sealing device,

a data carrier for storage of batch-specific data of the at least one test strip,

a data transmission device for wireless transmission of the batch-specific data and of the number of opening processes of the sealing device, and

b) an analysis module, said analysis module including

a device for measuring substance concentrations in the liquid media by the at least one test strip, and

a data-receiving device for wireless reception of the batch-specific data from the data transmission device and of the number of opening processes of the sealing device.

2. The measurement system of claim 1 wherein the data transmission device has at least one transponder.

3. The measurement system of claim 1 wherein the analysis module has a warning device formed to warn a user when a maximum number of opening processes has been exceeded.

4. The measurement system of claim 1 wherein the substance measurement device has an evaluation device for calculating the substance concentration as a function of the batch-specific data of the at least one test strip.

5. The measurement system of claim 1 wherein the test strip container in a closed state, is sealed off hermetically by the sealing device.

6. The measurement system of claim 1 wherein the substance measurement device has a device for measuring blood glucose concentrations.

7. The measurement system of claim 6 wherein the substance measurement device has a device for measuring blood fat concentrations.

8. The measurement system of claim 1 wherein the substance measurement device has a device for measuring blood fat concentrations.

9. The measurement system of claim 1 wherein the counter device is formed for counting a time duration of opening processes of the sealing device.

10. The measurement system of claim 1 wherein the data carrier is formed for storage of a number of opening processes of the sealing device.

11. The measurement system of claim 1 wherein the data carrier is formed for storage of a time duration of opening processes of the sealing device.

12. The measurement system of claim 1 wherein the data transmission device is formed for wireless transmission of the time duration of opening processes to the analysis module.

13. The measurement system of claim 1 wherein the data-receiving device is formed for the wireless reception of a time duration of opening processes.

14. The measurement system of claim 1 wherein the device for measuring blood glucose concentrations is an electrochemical measurement device.

15. The measurement system of claim 1 wherein the device for measuring blood glucose concentrations is an optical measurement device.

16. A portable analytical measurement system for measuring substance concentrations in liquid media, the system comprising:

a) a test strip container for receiving at least one test strip, said test strip container including

a sealing device,

a counter device for counting a time duration of opening processes of the sealing device,

a data carrier for storage of batch-specific data of the test strips and a time duration of opening processes,

a data transmission device for wireless transmission of the time duration of opening processes to an analysis module, and

b) an analysis module, said analysis module comprising

a device for measuring substance concentrations in liquid media by the at least one test strip, and

a data-receiving device for wireless reception of batch-specific data from the data transmission device and of the time duration of opening processes.

17. The measurement system of claim 16 wherein the analysis module has a warning device formed to warn a user when a maximum overall time duration of opening processes of the test strip container has been exceeded.

18. A method for measuring substance concentrations in liquid media, the method comprising the steps of:

providing a measurement system having a test strip container for receiving at least one test strip, said test strip container including a sealing device, a counter device for counting a number of opening processes of the sealing device, a data carrier for storage of batch-specific data of the test strips, a data transmission device for wireless transmission of batch-specific data and of the number of opening processes of the sealing device and an analysis module, said analysis module including a device for measuring substance concentrations in liquid media using the at least one test strip, and a data-receiving device for wireless reception of batch specific data from the data transmission device and of a number of opening processes,

recording a number of opening processes by the counter device and storing the number on the data carrier;

sending batch-specific data and a number of opening processes by wireless transmission to the analysis module, and

determining a substance concentration in the liquid medium by the at least one test strip.

19. The method of claim 18 further comprising the step of outputting a warning with the analysis module to a user when a maximum number of opening processes has been exceeded.

20. The method of claim 18 further comprising the steps of recording a time duration of opening processes by the counter device and storing the time on the data recorder.

21. The method of claim 20 further comprising the step of outputting a warning with the analysis module to a user when a maximum overall time duration of opening processes of the test strip container has been exceeded.
