Abstract

Method and apparatus including calling, retrieving and/or initiating a programmed function in conjunction with execution of one or more commands related to a closed loop control algorithm, receiving one or more data in response to the one or more commands over a data interface, and executing the one or more commands related to the closed loop control algorithm based on the received one or more data are provided.

Claims

1. A method, comprising:

initiating a programmed function in conjunction with execution of one or more commands related to a closed loop control algorithm;

receiving one or more data in response to the one or more commands over a data interface; and

executing the one or more commands related to the closed loop control algorithm based on the received one or more data.

2. The method of claim 1 wherein the programmed function is initiated based on an application programming interface (API) function.

3. The method of claim 1 wherein the closed loop control algorithm includes closed loop diabetes management algorithm.

4. The method of claim 1 wherein the closed loop control algorithm is configured to modify a delivery profile of a medication.

5. The method of claim 1 wherein the closed loop control algorithm is configured to request a blood glucose value.

6. The method of claim 1 wherein the one or more commands includes one or more serial commands.

7. The method of claim 6 wherein the received one or more data over the interface are serialized.

8. The method of claim 1 wherein the one or more commands includes a command to retrieve one or more of the current or prior monitored analyte level.

9. The method of claim 8 wherein the analyte level includes glucose level.

10. An apparatus, comprising:

a storage unit; and

one or more processors coupled to the storage unit, the one or more processors configured to initiate a programmed function in conjunction with execution of one or more commands related to a closed loop control algorithm, to receive one or more data in response to the one or more commands over a data interface, and to execute the one or more commands related to the closed loop control algorithm based on the received one or more data.

11. The apparatus of claim 10 wherein the programmed function is initiated based on an application programming interface function.

12. The apparatus of claim 10 wherein the one or more processors executing the closed loop control algorithm is configured to provide closed loop diabetes management algorithm.

13. The apparatus of claim 10 wherein the one or more processors executing the closed loop control algorithm is configured to modify a delivery profile of a medication.

14. The apparatus of claim 10 wherein the one or more processors executing the closed loop control algorithm is configured to request a blood glucose value.

15. The apparatus of claim 10 wherein the one or more commands includes one or more serial commands.

16. The apparatus of claim 15 wherein the received one or more data over the interface are serialized.

17. The apparatus of claim 10 wherein the one or more commands includes a command to retrieve one or more of the current or prior monitored analyte level.
