Abstract

The invention relates to an analysis appliance for analysis of blood samples, and to a user identification method integrated in the analysis appliance. The analysis appliance comprises a sampling device for taking blood samples, and an analysis device. A delivery device is also provided for transferring the blood samples from the sampling device to the analysis device, wherein the operating parameters concerning sampling, transfer of the sample to the analysis device, and analysis of the sample, can be adapted to the respective user. The operating parameters can be adapted by automatic, spontaneous execution of an automatically determined number of test measurements.

Claims

1. An analysis appliance for analysis of blood samples, comprising:

a sampling device for taking blood samples;

an analysis device;

a delivery device for transferring the blood samples from the sampling device to the analysis device; and

at least one pressure sensor for sensing and recording a pressure profile of a particular user, the analysis appliance being configured to compare the recorded pressure profile with a predetermined pressure profile stored in a database for the particular user.

2. The analysis appliance of claim 1, wherein the analysis appliance is configured to identify a particular user from the comparing of the recorded pressure profile to the predetermined pressure profile and at least partially permit use of the analysis appliance by the particular user, the analysis appliance being further configured to adapt operating parameters concerning sampling, transfer of the sample to the analysis device or analysis of the sample to the particular user.

3. The analysis appliance of claim 1, wherein the appliance is configured to adjust one or more of the operating parameters by automatic execution of one or more test measurements, the test measurements being determinable by a software control and stored in a database and retrieved.

4. The analysis appliance of claim 1, wherein the pressure sensor comprises a trigger.

5. The analysis appliance of claim 1, wherein the pressure sensor comprises a pressure-sensitive actuating member.

6. The analysis appliance of claim 5, wherein the actuating member comprises an appliance opening or cone configured for automatic blood collection.

7. The analysis appliance of claim 5, wherein the actuating member is connected to one or more mechanical switches which close one or more contacts when pressure is applied to the actuating member.

8. The analysis device of claim 5, wherein the actuating member rests on a yielding or spring-cushioned abutment.

9. The analysis appliance of claim 5, wherein the actuating member is operatively connected to the sampling device, whereby the sampling device can be activated by applying pressure to the actuating member.

10. The analysis appliance of claim 1, wherein the sampling device comprises a lancet for puncturing skin.

11. The analysis appliance of claim 1, wherein the sampling device comprises a capillary.

12. The analysis appliance of claim 10, wherein the depth of insertion of the lancet is regulated by data recorded by the sampling device.

13. The analysis appliance of claim 1, wherein the operating parameters of the analysis appliance automatically adapt to a particular user prior to a measurement operation.

14. The analysis appliance of claim 13, wherein the adaptation of the operating parameters is executed by software which communicates with hardware and which is controlled via user interfaces.

15. The analysis appliance of claim 14, wherein the software accesses databases in which the operating parameters are stored.

16. The analysis appliance of claim 14, wherein the software executes control functions concerning the operating parameters.

17. The analysis appliance of claim 14, wherein the software is activated by a user identification.

18. The analysis appliance of claim 17, wherein the user identification is executed through body contact with the analysis appliance.

19. The analysis appliance of claim 17, wherein the user identification is executed by

activation of a keyboard, a touch screen or a mouse, or by transferring data from a smart card.

20. The analysis appliance of claim 17, wherein the sampling device is controlled by the software.

21. The analysis appliance of claim 1, wherein the sampling device comprises at least one exchangeable lancet.

22. The analysis appliance of claim 21, wherein the lancet is replaceable.

23. The analysis appliance of claim 1, wherein the sampling device comprises a removable lancet magazine which contains several lancets.

24. The analysis appliance of claim 1, further comprising software that controls the analysis device.

25. The analysis appliance of claim 24, wherein the analysis device comprises optical or electrochemical measurement instruments.

26. The analysis appliance of claim 1, wherein the delivery device is controllable by software.

27. The analysis appliance of claim 1, wherein the analysis appliance determines glucose concentration.

28. The analysis appliance of claim 27, wherein the analysis appliance comprises a portable glucose meter.

29. A method of analyzing blood samples using an appliance comprising a sampling device for taking blood samples, an analysis device, and a delivery device for transferring the blood samples from the sampling device to the analysis device, the method comprising:

(a) operating the appliance in a learning mode in which user-specific parameters are obtained by exerting pressure on the appliance by the user;

(b) storing the user-specific parameters in a database; and

(c) operating the appliance in an operational mode using the user-specific parameters.

30. The method of claim 29, further comprising switching on the appliance and reading a user identification from the database.

31. The method of claim 30, wherein the user identification comprises a query concerning a user-specific pressure profile.

32. The method of claim 30, further comprising entering a password and making a query concerning the correlation between password and user.

33. The method of claim 29, wherein step (a) comprises the user contacting a body part with a pressure sensor disposed on the appliance.

34. An analysis appliance for analysis of blood samples, comprising:

a sampling device for taking blood samples;

an analysis device;

a delivery device for transferring the blood samples from the sampling device to the analysis device;

an actuating member comprising a pressure sensor; and

software configured to correlate a signal from the pressure sensor to the identity of the user operating the analysis appliance or to the identity of the body part contacting the pressure sensor.

35. The analysis appliance of claim 34, wherein the actuating member comprises a switch.

36. The analysis appliance of claim 34, wherein the actuating member comprises an opening configured to receive a blood sample.

37. The analysis appliance of claim 36, wherein the actuating member comprises a spring.

38. The analysis appliance of claim 34, wherein the software is configured to correlate the signal from the pressure sensor to the identity of the user.
