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 system for continuous measurement of an analyte in a host, the system comprising:

a continuous analyte sensor configured to measure a concentration of an analyte in a host; and

a sensor electronics module physically connected to the continuous analyte sensor during operation of the continuous analyte sensor, wherein the sensor electronics module is configured to process a data stream associated with an analyte concentration measured by the continuous analyte sensor and to generate displayable sensor information based on at least some sensor data of the data stream, wherein the sensor electronics module comprises;

a storage device configured to store at least some of the displayable sensor information; and

a telemetry module configured to wirelessly transmit a first portion of the displayable sensor information to a first display device, wherein the first portion of displayable sensor information is formatted for display on the first display device, and to wirelessly transmit a second portion of the displayable sensor information to a second display device, wherein the second portion of displayable sensor information is formatted for display on the second display device.

2. The system of claim 1, wherein the first and second portions of the displayable sensor information each comprise a common subset of the displayable sensor information and the first portion also includes an additional subset of the displayable sensor information that is not included in the second portion.

3. The system of claim 1, wherein the telemetry module is further configured to wirelessly transmit a third portion of the displayable sensor information to a third display device, wherein the third portion of displayable sensor information is formatted for display on the third display device.

4. The system of claim 1, wherein the sensor electronics module is configured to communicate simultaneously with the first and second display devices.

5. The system of claim 1, wherein the first portion of the displayable sensor information is transmitted via at least the internet and the second portion of the displayable sensor information is transmitted via at least a cellular telephone network.

6. The system of claim 5, wherein the second portion of the displayable sensor information comprises at least one short messaging service message.

7. The system of claim 1, wherein the first portion of displayable sensor information is selected based at least on a type of the first display device.

8. The system of claim 3, wherein display devices types include one or more of portable dumb devices, hand-held display devices, mobile devices, mobile phones, single point analyte monitor, drug delivery device, medical device, smart phones, laptop computer, desktop computers, and electronic medical records systems.

9. The system of claim 1, wherein the sensor electronics module is further configured to determine if one or more sets of alert conditions are satisfied by the sensor data.

10. The system of claim 9, wherein each set of alert conditions is associated with one or more delivery actions, wherein each delivery action indicates at least one display device to at least a portion of the displayable sensor information is to be transmitted.

11. The system of claim 10, wherein the telemetry module transmits the first portion of the displayable sensor information in response to the sensor electronics module determining that a first set of alert conditions are satisfied by the sensor data.

12. The system of claim 10, wherein a first set of alert conditions are associated with a hypoglycemic alert, wherein satisfaction of the alert conditions of the first set indicates that the host is in a hypoglycemic state.

13. The system of claim 12, wherein a second set of alert conditions are associated with a hyperglycemic alert, wherein satisfaction of the alert conditions of the second set indicates that the host is in a hyperglycemic state.

14. The system of claim 1, further comprising another sensor that senses one or more characteristics associated with the host.

15. The system of claim 14, wherein the another sensor is selected from the group comprising a temperature sensor, a heart rate sensor, an altimeter, a pedometer, and an accelerometer.

16. The system of claim 1, wherein the displayable sensor information further comprises one or more calibrated analyte concentration values, rate of change information, trend information, alarm information, sensor diagnostic information and/or calibration information.

17. The system of claim 1, wherein the sensor electronics module is configured to determine the first portion of displayable sensor information to transmit to the first display device based at least on a query received from the first display device.
