Abstract

Systems, devices, and methods are provided for the management of multiple sensor control devices and/or multiple reader devices in an in vivo analyte monitoring environment, and also for resolving conflicts when merging data collected by different reader devices.

Claims

1. A method of pairing devices in an in vivo analyte monitoring environment, the method comprising:

sending, by a second reader device, a first communication comprising a token to a sensor control device that has already communicated with a first reader device, wherein the sensor control device is adapted for in vivo analyte sensing;

if the token is valid for the sensor control device, then sending, by the sensor control device, data indicative of a sensed analyte level to the second reader device; and

if the token is not valid for the sensor control device, then sending, by the sensor control device, a communication to the second reader device that indicates that the token is not valid.

2. The method of claim 1, wherein the second reader device is a smartphone.

3. The method of claim 1, wherein the first communication further comprises a request for data indicative of the analyte level of the user.

4. The method of claim 1, further comprising:

communicating the token to the second reader device prior to sending the token to the sensor control device.

5. The method of claim 4, wherein the token is communicated to the second reader device by manually typing the token into the second reader device.

6. The method of claim 5, wherein the token is printed on packaging for the sensor control device.

7. The method of claim 5, wherein the token is displayed by the first reader device.

8. The method of claim 4, wherein the token is communicated to the second reader device automatically.

9. The method of claim 8, wherein the token is in the form of a bar-code and is communicated automatically to the second reader device using an optical scanner of the second reader device.

10. The method of claim 8, wherein the token is communicated wirelessly to the reader device using a Near Field Communication or Bluetooth protocol.

11. The method of claim 1, further comprising:

activating the sensor control device with the first reader device;

entering the token into the first reader device; and

sending the token from the first reader device to the sensor control device such that the sensor control device can store the token for later use.

12. The method of claim 11, further comprising:

sending, from the first reader device, a request for data indicative of the analyte level of the user to the sensor control device, wherein the request includes the token.

13. The method of claim 12, further comprising:

determining, by the sensor control device, whether the token contained in the request from the first reader device is valid; and

if the token is valid, then sending the data indicative of the analyte level of the user to the first reader device.

14. The method of claim 13, further comprising:

communicating the token to the second reader device prior to sending, by the second reader device, the first communication comprising the token to the sensor control device.

15. The method of claim 13, wherein the sensor control device is programmed to respond to a request for data indicative of the analyte level from any one of a plurality of three or more reader devices provided that the reader device that sends the request also communicates the token to the sensor control device, and the sensor control device determines that the token is valid.

16. The method of claim 11, further comprising:

estimating, by the second reader device, either a time at which the sensor control device was activated by the first reader device or a duration of time during which the sensor control device has been active.

17. The method of claim 11, further comprising:

receiving, by the second reader device, a communication from the first reader device comprising either a time at which the sensor control device was activated by the first reader device or a duration of time during which the sensor control device has been active.

18. The method of claim 1, wherein the sensor control device is programmed to allow pairing at any time during an operating life of the sensor control device.

19. The method of claim 1, wherein the sensor control device is a first sensor control device, the method further comprising pairing the second reader device with a second sensor control device while the first sensor control device remains active.

20. The method of claim 19, wherein the first sensor control device and the second sensor control device are to sense analyte levels of the same user.
