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.

First claim

What is claimed is:

1. A system, comprising:
a control unit including a memory having stored therein a plurality of closed loop control algorithms for execution and a serializer configured to initiate one or more application programming interface functions associated with one or more operations of a medication delivery device, the medication delivery device configured for communication with the control unit for executing one or more medication delivery functions based on one or more signals received from the control unit;
wherein the control unit is configured to retrieve a first stored closed loop control algorithm for execution from the plurality of stored closed loop control algorithms,
wherein the first closed loop control algorithm is compatible with both the control unit and the medication delivery device without the first closed loop control algorithm being modified, and
wherein the serializer is configured such that the first closed loop control algorithm can be replaced with a second closed loop control algorithm from the plurality of stored closed loop control algorithms without modifying the control unit.

2. The system of claim 1 , wherein the medication delivery device is configured to execute the one or more medication delivery functions.

3. The system of claim 1 , wherein the control unit includes a deserializer.

4. The system of claim 1 , wherein the one or more application programming interface functions are related to one or more of a medication delivery profile, a medication delivery modification, a safety shut off routine, operational status monitoring, and a data processing mode.

5. The system of claim 1 , further comprising an analyte monitoring device configured for communication with the control unit.

6. The system of claim 5 , wherein the one or more application programming interface functions is related to one or more of analyte monitoring, a frequency of analyte data logging, a diagnosis of an analyte sensor operation, at least one failure mode related to an analyte sensor, and an analyte sensor replacement schedule.

7. The system of claim 5 , wherein the analyte monitoring device is configured to monitor real time analyte level over a predetermined time period.

8. The system of claim 1 , further comprising a transport layer between the control unit, the medication delivery device, and a computer terminal.

9. The system of claim 1 , wherein the plurality of closed loop control algorithms are compatible with both the control unit and the medication delivery device without the plurality of closed loop control algorithms being modified.

10. An apparatus, comprising:
a control unit including a memory unit having stored therein a plurality of closed loop control algorithms for execution and a serializer configured to initiate one or more application programming interface functions associated with one or more operations of a medication delivery device configured for communication with the control unit, and the control unit configured to retrieve a first stored closed loop control algorithm for execution from the plurality of stored closed loop control algorithms,
wherein the first closed loop control algorithm is compatible with both the control unit and the medication delivery device without the first closed loop control algorithm being modified, and
wherein the serializer is configured such that the first closed loop control algorithm can be replaced with a second closed loop control algorithm from the plurality of stored closed loop control algorithms without modifying the control unit.

11. The apparatus of claim 10 , wherein the medication delivery device is configured to execute one or more medication delivery functions.

12. The apparatus of claim 10 , wherein the control unit includes a deserializer.

13. The apparatus of claim 10 , wherein the one or more application programming interface functions are related to one or more of a medication delivery profile, a medication delivery modification, a safety shut off routine, operational status monitoring, and a data processing mode.

14. The apparatus of claim 10 , further comprising an analyte monitoring device configured for communication with the control unit.

15. The apparatus of claim 14 , wherein the analyte monitoring device is configured to monitor real time analyte level over a predetermined time period.

16. The apparatus of claim 14 , wherein the one or more application programming interface functions is related to one or more of analyte monitoring, a frequency of analyte data logging, a diagnosis of an analyte sensor operation, at least one failure mode related to an analyte sensor, and an analyte sensor replacement schedule.

17. The apparatus of claim 10 , further comprising a transport layer between the control unit, the medication delivery device, and a computer terminal.

18. The apparatus of claim 10 , wherein the plurality of closed loop control algorithms are compatible with both the control unit and the medication delivery device without the plurality of closed loop control algorithms being modified.
