Abstract

Systems and methods for a continuous monitoring of analyte values received from an analyte sensor system are provided. One method for a wireless data communication between an analyte sensor system and a mobile device involves storing identification information associated with a transceiver of the analyte sensor system, the identification information entered by a user of the mobile device via a custom application running on the mobile device; causing the custom application to enter a background mode; searching for advertisement signals; receiving an advertisement signal from the transceiver; authenticating the transceiver based on the identification information; prompting the user to bring the custom application to a foreground mode; causing the custom application to request a confirmation from the user that a data connection with the transceiver is desired; receiving the confirmation from the user; and completing the data connection with the transceiver.

First claim

What is claimed is:

1. A passive medical system configured for wireless data communication with an analyte sensor system, the passive medical system comprising:
one or more memories for storing instructions and identification information associated with the analyte sensor system;
an insulin pump;
a wireless receiver configured to receive a wireless signal associated with an analyte value, wherein the analyte value is measured by the analyte sensor system; and
a processor operatively coupled to the one or more memories and the wireless receiver, wherein the processor is configured to execute the instructions to:
receive an advertisement signal from the analyte sensor system, wherein the advertisement signal comprises the analyte value measured by the analyte sensor system, and the advertisement signal is encrypted based on the identification information associated with the analyte sensor system so that a device that has the identification information can decrypt the analyte value;
extract the analyte value from the advertisement signal; and
perform a function associated with the insulin pump based on the extracted analyte value.

2. The passive medical system of claim 1 , wherein the analyte value is encoded, and the extracting comprises decoding the encoded analyte value based on the identification information associated with the analyte sensor system.

3. The passive medical system of claim 1 , wherein the analyte value is associated with a glucose value.

4. The passive medical system of claim 1 , wherein the passive medical system is configured to receive data from the analyte sensor system without having a dedicated data communication channel with the analyte sensor system.

5. The passive medical system of claim 1 , wherein the extracted analyte value is used for at least one of calculating an optimal insulin administration rate and suspending insulin administration when a glucose value falls below a threshold value.

6. The passive medical system of claim 1 , further comprising a display device.

7. The passive medical system of claim 6 , wherein the display device is configured to display the extracted analyte value.

8. The passive medical system of claim 1 , wherein the passive medical system is configured to receive input of a serial number associated with the analyte sensor system.

9. The passive medical system of claim 8 , wherein the identification information associated with the analyte sensor system is based on the serial number associated with the analyte sensor system.

10. A method for wireless data communication with an analyte sensor system, the method comprising:
receiving, via a wireless receiver of a passive medical system, an advertisement signal from the analyte sensor system, wherein the advertisement signal comprises an analyte value measured by the analyte sensor system, a memory of the passive medical system storing identification information associated with the analyte sensor system, wherein the advertisement signal is encrypted based on the identification information associated with the analyte sensor system so that a device that has the identification information can decrypt the analyte value;
extracting the analyte value from the advertisement signal; and
performing a function associated with an insulin pump based on the extracted analyte value.

11. The method of claim 10 , further comprising receiving, via the passive medical system, input of a serial number associated with the analyte sensor system.

12. The method of claim 11 , wherein the identification information associated with the analyte sensor system is based on the serial number associated with the analyte sensor system.

13. The method of claim 10 , wherein the analyte value is associated with a glucose value.

14. The method of claim 10 , wherein the passive medical system is configured to receive data from the analyte sensor system without having a dedicated data communication channel with the analyte sensor system.

15. The method of claim 10 , wherein the extracted analyte value is used for at least one of calculating an optimal insulin administration rate and suspending insulin administration when a glucose value falls below a threshold value.

16. The method of claim 10 , further comprising, displaying, via a display device of the passive medical system, the extracted analyte value.

17. The method of claim 10 , wherein the analyte value is encoded, and the extracting comprises decoding the encoded analyte value based on the identification information associated with the analyte sensor system.
