Abstract

An integrated analyte measurement system includes a housing and a disposable configured to be positioned in the housing. A plurality of penetrating members are positioned in the disposable. A penetrating member driver is configured to be coupled to each of a penetrating member. A plurality of analyte sensors are positioned in the disposable. The disposable houses both used and unused penetrating members and analyte sensors.

First claim

What is claimed is:

1. An integrated analyte measurement system, comprising:
a housing;
a disposable configured to be positioned in the housing;
a plurality of penetrating members positioned in the disposable;
a driver configured to be coupled to the penetrating member, the driver coupled to a processor and having position and velocity sensing capabilities to advance a penetrating member into a target tissue to create a wound from which body fluid will flow, the processor and driver providing control of drive power to a penetrating member and velocity of the penetrating member to account for variations in a skin thickness during advance of the penetrating member to create the wound; and
a plurality of analyte sensors positioned in the disposable, the disposable housing used and unused penetrating members as well as analyte sensors.

2. The system of claim 1 , wherein the driver is an electromechanical driver.

3. The system of claim 1 , wherein the system provides for electronic control of penetrating member trajectory during skin cutting.

4. The system of claim 1 , further comprising:
a display; and
a user interface.

5. The system of claim 1 , further comprising:
a shutter that covers at least a portion of a front end of the housing.

6. The system of claim 5 , wherein a testing mode of the system is initiated by opening the shutter.

7. The system of claim 1 , further comprising:
resources that include a microprocessor which provides at least one of, data processing, calibration curves and look-up tables.

8. The system of claim 1 , further comprising:
at least one indexer for indexing the plurality of analyte sensors and penetrating members.

9. The system of claim 1 , wherein the housing includes a front end with a skin stabilizer.

10. The system of claim 1 , wherein the plurality of penetrating members are coupled to a support, the support being coupled to a frame that includes the plurality of analyte sensors.

11. The system of claim 1 , further comprising:
at least one sterility seal and at least one humidity seal.

12. The system of claim 11 , further comprising:
an opening member for opening at least one of, the at least one sterility seal and the humidity seal.

13. The system of claim 1 , further comprising:
a desiccant positioned in an interior of at least one of the housing and the disposable.

14. The system of claim 3 , wherein the electronic control provides for control of penetrating member position and velocity profile during an entire lancing process of the penetrating member.

15. The system of claim 3 , wherein the system has an electronic brake for each of a penetrating member.

16. The system of claim 3 , wherein the system provides for control of drive power to a penetrating member and a lancing speed to account for variations in skin thickness.

17. The system of claim 1 , wherein each of an analyte sensor includes three electrodes positioned in a sample chamber.

18. The system of claim 1 , wherein each analyte sensor is a glucose sensor with three electrodes positioned in a sample chamber.

19. The system of claim 18 , wherein a mediator is included as part of a working electrode.

20. The system of claim 19 , wherein the mediator is not a separate element from the working electrode.

21. The system of claim 18 , wherein each glucose sensor includes a conductive layer, insulating layer, a reference electrode, a counter electrode and a working electrode.

22. The system of claim 21 , wherein each glucose sensor includes a hydrophilic membrane, spacer layer and adhesive layer.

23. The system of claim 18 , wherein the analyte sensors are screen-printed.

24. The system of claim 23 , wherein a carbon paste is provided on top of a substrate to form conducting layers for a screen-printed three-electrode system.

25. The system of claim 1 , wherein during sample acquisition and measurement a tip of a penetrating member remains within an associated analyte sensor.
