Abstract

Method and system for providing data monitoring and management including RF communication link over which a transmitter and a receiver is configured to communicate, the transmitter configured to periodically transmit a data packet associated with a detected analyte level received from an analyte sensor, and the receiver configured to identify the transmitter as the correct transmitter for which it is configured to receive the data packets, and to continue to receive the data packets from the transmitter once the transmitter identification has been verified, is provided.

Claims

1. A data monitoring and management system, comprising:

a communication link;

a transmitter operatively coupled to the communication link, the transmitter configured to transmit a data packet; and

a receiver operatively coupled to the communication link, the receiver configured to receive transmitted data packet, the receiver further configured to receive one or more further data packets from the transmitter when the transmitter identification is verified.

2. The system of claim 1 wherein the communication link includes an RF communication link.

3. The system of claim 1 wherein the transmitter is configured to transmit the data packet at each predetermined time interval.

4. The system of claim 3 wherein the predetermined time interval is one minute.

5. The system of claim 1 wherein the receiver is further configured to perform error correction on the received data packet.

6. The system of claim 1 wherein the receiver is configured to verify the transmitter identification based on the transmitter identification information encoded with the data packet.

7. The system of claim 1 further including a sensor configured to detect one or more glucose levels, wherein the sensor is configured to be in signal communication with the transmitter.

8. The system of claim 7 wherein the sensor is disposed substantially in physical contact with the transmitter.

9. The system of claim 7 wherein the transmitter is configured to convert a sensor signal received from the sensor into a corresponding data for transmission to the receiver.

10. The system of claim 7 further including a medication delivery unit operatively coupled to the receiver, the medication delivery unit configured to determine a medication administration protocol based on the signals received from the receiver.

11. The system of claim 10 wherein the medication delivery unit includes an insulin pump, and further wherein the medication administration protocol includes one or more of a bolus calculation, and a basal profile modification.

12. The system of claim 10 wherein the receiver is configured to determine a glucose level corresponding to the sensor signal, and further, wherein the receiver is configured to output the glucose level information.

13. The system of claim 10 wherein the medication delivery unit is configured to wirelessly communicate with the receiver.

14. A continuous glucose monitoring and management system, comprising:

an RF communication link;

a transmitter operatively coupled to the communication link, the transmitter configured to periodically transmit a data packet at each predetermined time interval; and

a receiver operatively coupled to the communication link, the receiver configured to receive a first transmitted data packet, the receiver further configured to receive one or more subsequent data packets from the transmitter when the transmitter identification is verified;

wherein the receiver is configured to verify the transmitter identification based on the transmitter identification information encoded with the first transmitted data packet.

15. The system of claim 14 wherein the data packets received from the transmitter correspond to a respective measured glucose level of a patient.

16. The system of claim 15 further including an insulin pump operatively coupled to the receiver, the insulin pump configured to determine an insulin administration protocol based on the signals received from the receiver.

17. The system of claim 16 wherein the insulin administration protocol includes one or more of a bolus determination, and a basal rate modification determination.

18. The system of claim 16 wherein the insulin pump is disposable.

19. The system of claim 14 wherein the predetermined time interval for transmitter data packet transmission includes one transmission per minute.

20. A method of providing continuous glucose monitoring and management system, comprising the steps of:

providing an RF communication link;

periodically transmitting a data packet at each predetermined time interval over the RF communication link;

receiving a first transmitted data packet over the RD communication link; and

receiving one or more subsequent data packets over the RF communication link when the transmission identification is verified from the first transmitted data packet.
