Abstract

Systems and methods for continuous measurement of an analyte in a host are provided. The system generally includes a continuous analyte sensor configured to continuously measure a concentration of analyte in a host and a sensor electronics module physically connected to the continuous analyte sensor during sensor use, wherein the sensor electronics module is further configured to directly wirelessly communicate displayable sensor information to a plurality of different types of display devices.

Claims

1. A method for transmitting glucose data generated by a continuous glucose sensor to a display device, comprising:

providing a plurality of predefined delivery options stored in memory of a sensor electronics module, each of the plurality of predefined delivery options including a transmission protocol by which to transmit sensor data;

storing glucose sensor data in memory at a sensor electronics module, the glucose sensor data generated by a continuous glucose sensor coupled to the sensor electronics;

receiving, by the sensor electronics module, a request for particular sensor data of the stored sensor data from a display device; and

transmitting, using the sensor electronics module, the requested sensor data to the display device,

wherein the requested sensor data is transmitted according to a first, default delivery option of the plurality of predefined delivery options when no request for particular delivery options is indicated in the request, and

wherein the requested data is transmitted according to a second delivery option of the plurality of predefined delivery options when the request includes an indication of the second delivery option, the second delivery option using a different transmission protocol than the default delivery option.

2. The method of claim 1, wherein the request for sensor data includes a timeframe of requested sensor data.

3. The method of claim 1, wherein the first delivery option uses a different data delivery format for transmitting the sensor data than the second delivery option.

4. The method of claim 1, wherein the plurality of predefined delivery options are defined in a data structure stored in the memory of the sensor electronics module.

5. The method of claim 1, wherein the plurality of predefined delivery options each define the sensor data to transmit and a data packet format by which the sensor data is to be transmitted.

6. A sensor electronics module for transmitting glucose data generated by a continuous glucose sensor to a display device, comprising:

memory for storing;

(i) a plurality of predefined delivery options, each of the plurality of predefined delivery options including a transmission protocol by which to transmit sensor data, and (ii) the glucose sensor data generated by a continuous glucose sensor coupled to the sensor electronics;

a transceiver for receiving a request for particular sensor data of the stored sensor data from a display device and transmitting the requested sensor data to the display device; and

a processor that causes the transceiver to transmit according to a first, default delivery option of the plurality of predefined delivery options when no request for particular delivery options is indicated in the request and transmit according to a second delivery option of the plurality of predefined delivery options when the request includes an indication of the second delivery option, wherein the second delivery option uses a different transmission protocol than the default delivery option.

7. The system of claim 6, wherein the request for sensor data includes a timeframe of requested sensor data.

8. The system of claim 6, wherein the first delivery option uses a different data delivery format for transmitting the sensor data than the second delivery option.

9. The system of claim 6, wherein the plurality of predefined delivery options are defined in a data structure stored in the memory of the sensor electronics module.

10. The system of claim 6, wherein the plurality of predefined delivery options each define the sensor data to transmit and a data packet format by which the sensor data is to be transmitted.

11. A non-transitory computer-readable medium with instructions stored thereon, that when executed by a processor, perform the steps of:

providing a plurality of predefined delivery options stored in memory of a sensor electronics module, each of the plurality of predefined delivery options including a transmission protocol by which to transmit sensor data;

storing glucose sensor data in memory at a sensor electronics module, the glucose sensor data generated by a continuous glucose sensor coupled to the sensor electronics;

receiving, by the sensor electronics module, a request for particular sensor data of the stored sensor data from a display device; and

transmitting, using the sensor electronics module, the requested sensor data to the display device,

wherein the requested sensor data is transmitted according to a first, default delivery option of the plurality of predefined delivery options when no request for particular delivery options is indicated in the request, and

wherein the requested data is transmitted according to a second delivery option of the plurality of predefined delivery options when the request includes an indication of the second delivery option, the second delivery option using a different transmission protocol than the default delivery option.

12. The computer-readable medium of claim 11, wherein the request for sensor data includes a timeframe of requested sensor data.

13. The computer-readable medium of claim 11, wherein the first delivery option uses a different data delivery format for transmitting the sensor data than the second delivery option.

14. The computer-readable medium of claim 11, wherein the plurality of predefined delivery options are defined in a data structure of the computer-readable medium.

15. The computer-readable medium of claim 11, wherein the plurality of predefined delivery options each define the sensor data to transmit and a data packet format by which the sensor data is to be transmitted.
