Abstract

Methods and devices to detect analyte in body fluid are provided. Embodiments include enhanced analyte monitoring devices and systems.

Claims

1. An glucose monitoring system, comprising:

an analyte sensor having a portion in fluid contact with an interstitial fluid under a skin layer;

an on body unit operatively coupled to the analyte sensor, the on body unit receiving analyte related signals from the analyte sensor and storing the analyte related signals in a memory until a data transfer request is received, the on body unit transmitting the analyte related signals in response to the data transfer request; and

a glucose meter including a processor, the glucose meter providing the data transfer request, and further receiving the analyte related data on demand from the on body unit.

2. The system of claim 1 wherein the on body unit stores the analyte related signals in the memory without a data transmission attempt until the data transfer request is received from the glucose meter.

3. The system of claim 1 wherein the on body unit receives the data transfer request when the on body unit is in signal communication with the glucose meter.

4. The system of claim 1 wherein the on body unit transmits the analyte related signals only in response to the data transfer request.

5. The system of claim 1 wherein the glucose meter includes a memory for storing the analyte related signals received from the on body unit in response to the data transfer request.

6. The system of claim 1 wherein the analyte sensor is a glucose sensor.

7. The system of claim 1 wherein the on body unit receives the data transfer request based on radio frequency (RF) communication protocol.

8. The system of claim 1 wherein the glucose meter includes an output unit to output the received analyte related signals under the control of the processor.

9. The system of claim 8 wherein the output unit outputs an audible indicator, a visual indicator, a vibratory indicator, or one or more combinations thereof.

10. The system of claim 1 wherein the on body unit does not continuously broadcast the analyte related signals.

11. The system of claim 1 wherein the on body unit transmits a current glucose data and one or more prior glucose data in response to the data transfer request.

12. The system of claim 1 wherein the glucose meter includes a strip port to receive an in vitro test strip.

13. The system of claim 12 wherein the glucose meter outputs an indication based on a glucose measurement from a blood sample received from the in vitro test strip.

14. The system of claim 1 wherein the analyte sensor requires no system calibration.

15. The system of claim 1 wherein the analyte sensor requires no user calibration.

16. The system of claim 1 wherein the analyte sensor is automatically calibrated.

17. The system of claim 1 wherein the processor of the glucose meter performs data analysis of the analyte related signals received from the on body unit.

18. The system of claim 17 wherein processor of the glucose meter performs data analysis of the received analyte related signals based a blood glucose measurement.

19. The system of claim 17 wherein the glucose meter displays a trend based on the received analyte related signals.
