Abstract

Systems, devices and methods are provided that allow for enhanced performance, power efficiency, interoperability, data security and user privacy for in vivo analyte monitoring systems that utilize wireless communications. The in vivo analyte monitoring systems can include a Bluetooth or Bluetooth Low Energy enabled handheld relay device for wirelessly relaying analyte data between a sensor unit device and one or more reader devices. The in vivo analyte monitoring systems can employ advertisement and encryption schemes for wirelessly transmitting data in a manner that allows for improved security, efficiency and privacy.

First claim

What is claimed is:

1 . An in vivo glucose monitoring system comprising:
a sensor control device comprising:
a glucose sensor, wherein at least a portion of the glucose sensor is configured to be in fluid contact with a bodily fluid of a subject;
wireless communication circuitry comprising a transceiver adapted to wirelessly transmit and receive data according to a Bluetooth or Bluetooth Low Energy protocol;
one or more processors;
memory on which one or more instructions are stored that, when executed by the one or more processors of the sensor control device, cause the sensor control device to:
establish a paired connection according to the Bluetooth or Bluetooth Low Energy protocol with a reader device; and
transmit periodically to the reader device, one or more advertisement packets according to the Bluetooth or Bluetooth Low Energy protocol without being concurrently paired with the reader device according to the Bluetooth or Bluetooth Low Energy communication protocol, wherein the one or more advertisement packets comprise an advertising payload section, wherein the advertising payload section comprises data indicative of a glucose level of the subject from the sensor control device; and

the reader device comprising;
one or more processors;
wireless communication circuitry adapted to communicate with the sensor control device; and
memory on which one or more instructions are stored that, when executed, cause the one or more processors of the reader device to read the data indicative of the glucose level of the subject from the advertising payload section of the one or more advertisement packets,
wherein the sensor control device is adapted to stop periodic transmission of the one or more advertisement packets after receipt of a confirmation from the reader device and wherein the sensor control device is adapted to restart periodic transmission of the one or more advertisement packets after a new glucose level of the user is sensed, wherein data indicative of the sensed new glucose level is contained within the one or more advertisement packets of the restarted periodic transmission.

2 . The in vivo glucose monitoring system of claim 1 , wherein the data indicative of the glucose level of the subject is encrypted.

3 . The in vivo glucose monitoring system of claim 1 , wherein the one or more advertisement packets further comprise an advertising header section.

4 . The in vivo glucose monitoring system of claim 3 , wherein the advertising header section comprises an address associated with the sensor control device.

5 . The in vivo glucose monitoring system of claim 1 , wherein the one or more advertisement packets are transmitted at a predetermined interval.

6 . The in vivo glucose monitoring system of claim 1 , wherein the instructions, when executed by the one or more processors, further cause the one or more processors to transmit an identifier prior to transmitting the one or more advertising packets.

7 . The in vivo glucose monitoring system of claim 1 , wherein the one or more reader devices comprise a smartphone.

8 . The in vivo glucose monitoring system of claim 1 , wherein the advertising payload section comprises two or more most recent glucose level measurements of the subject from the sensor control device.

9 . The in vivo glucose monitoring system of claim 8 , wherein the memory of the reader device on which one or more instructions are stored that, when executed by the one or more processors of the reader device, further cause the one or more processors of the reader device to reconstruct recent glucose level trends of the subject based on the two or more most recent glucose level measurements of the subject.

10 . The in vivo glucose monitoring system of claim 1 , wherein the one or more advertising packets are connectable undirected advertising packets.

11 . The in vivo glucose monitoring system of claim 1 , wherein the one or more advertising packets are connectable directed advertising packets.

12 . The in vivo glucose monitoring system of claim 1 , wherein the one or more advertising packets are non-connectable undirected advertising packets.

13 . The in vivo glucose monitoring system of claim 1 , wherein the one or more advertising packets are scannable undirected advertising packets.

14 . The in vivo glucose monitoring system of claim 1 , wherein the one or more advertisement packets are transmitted at a variable interval to conserve battery life.

15 . A method of communicating in an in vivo glucose monitoring system, the method comprising:
establishing a paired connection between a sensor control device and a reader device using a Bluetooth or Bluetooth Low Energy protocol; transmitting periodically, by the sensor control device to the reader device, one or more advertisement packets using the Bluetooth or Bluetooth Low Energy protocol without being concurrently paired with the reader device according to the Bluetooth or Bluetooth Low Energy communication protocol, wherein the one or more advertisement packets comprise an advertising payload section, wherein the advertising payload section comprises data indicative of a glucose level of the subject from the sensor control device; reading, by the reader device, the data indicative of the glucose level of the subject from the advertising payload section of the one or more advertisement packets; stopping periodic transmission of the one or more advertisement packets after receipt of a confirmation from the reader device; and restarting periodic transmission of the one or more advertisement packets after sensing a new glucose level of the user, wherein data indicative of the sensed new glucose level is contained within the one or more advertisement packets of the restarted periodic transmission.

16 . The method of claim 15 , wherein the data indicative of the glucose level of the subject is encrypted.

17 . The method of claim 15 , wherein the one or more advertisement packets further comprise an advertising header section.

18 . The method of claim 17 , wherein the advertising header section comprises an address associated with the sensor control device.

19 . The method of claim 15 , wherein the one or more advertisement packets are transmitted at a predetermined interval.

20 . The method of claim 15 , further comprising: transmitting an identifier prior to transmitting the one or more advertising packets.

21 . The method of claim 15 , wherein the one or more reader devices comprise a smartphone.
