Abstract

Methods and devices to monitor an analyte in body fluid are provided. Embodiments include continuous or discrete acquisition of analyte related data from a transcutaneously positioned in vivo analyte sensor automatically or upon request from a user.

Claims

1. An apparatus for bi-directional communication in an analyte monitoring system, comprising:

a storage device having stored therein one or more routines;

a processing unit operatively coupled to the storage device and configured to retrieve the stored one or more routines for execution;

a data transmission component operatively coupled to the processing unit and configured to transmit data based at least in part on the one or more routines executed by the processing unit; and

a data reception component operatively coupled to the processing unit and configured to receive analyte related data from a remote location and to store the received analyte related data in the storage device for retransmission;

wherein the data transmission component is programmed to transmit a query to a remote location; and

further

wherein the data reception component receives the analyte related data from the remote location in response to the transmitted query when one or more electronics in the remote location transitions from an inactive state to an active state upon detection of the query from the data transmission component.

2. The apparatus of claim 1 wherein the data transmission component transmits the query at a predetermined time interval.

3. The apparatus of claim 2 wherein the predetermined time interval is programmable.

4. The apparatus of claim 1 wherein the data transmission component transmits data wirelessly.

5. The apparatus of claim 1 wherein the data reception component receives data wirelessly.

6. The apparatus of claim 1 wherein the remote location includes an analyte sensor.

7. The apparatus of claim 6 wherein the data received includes sensor related data.

8. The apparatus of claim 6 wherein the analyte sensor includes a glucose sensor.

9. The apparatus of claim 1 wherein the data reception component is coupled to the storage unit and further, wherein the received data is stored in the storage unit.

10. The apparatus of claim 1 wherein the data transmission component is further configured to transmit the received data to a remote device.

11. The apparatus of claim 10 wherein the remote device includes one or more of an analyte monitoring device, a blood glucose meter, a remote terminal, or a communication device.

12. The apparatus of claim 1 wherein the data reception component is configured to receive one or more instructions to update the processing unit.

13. The apparatus of claim 12 wherein the received one or more instructions updates the one or more routines for execution by the processing unit.

14. The apparatus of claim 1 wherein the data reception component is configured to receive a plurality of data points concurrently from the remote location.

15. The apparatus of claim 14 wherein the plurality of data points includes one or more of the current glucose data and a prior glucose data.

16. The apparatus of claim 1 wherein the storage unit includes a random access memory (RAM), an erasable programmable read only memory (EPROM), an electrically erasable programmable read only memory (EEPROM) or a flash memory.

17. The apparatus of claim 1 wherein the storage unit includes a non-volatile memory.

18. The apparatus of claim 1 wherein the storage unit is integrated in the processing unit.

19. The apparatus of claim 1 wherein the data processing unit and the storage unit comprises an application specific integrated circuit (ASIC).

20. The apparatus of claim 1 wherein the data transmission component and the data reception component include a data transceiver.

21. The apparatus of claim 1 wherein the data transmission component or the data reception component or both are configured for data communication using one or more of an RF communication protocol, a Bluetooth communication protocol, a Zigbee communication protocol, or a 802.11 wireless Local Area Network (LAN) communication protocol.
