Integrated insulin delivery system with continuous glucose sensor
Systems and methods for integrating a continuous glucose sensor 12 , including a receiver 14 , a medicament delivery device 16 , a controller module, and optionally a single point glucose monitor 18 are provided. Integration may be manual, semi-automated and/or fully automated.
1. A method for diabetes management, the method comprising:
controlling insulin delivery to a host, using a processor comprising a controller module;
iteratively evaluating internally derived data relative to a predetermined glucose boundary; and
selectively turning the controller on or off responsive to the iterative evaluation,
wherein the internally derived data comprise processed glucose data and insulin on-board information, and wherein the interatively evaluating comprises interatively evaluating the insulin on board information.
2. The method of claim 1 , wherein the selectively turning the controller on or off comprises selectively turning the insulin delivery off when the processed glucose sensor data meets a predetermined criterion relative to the predetermined glucose boundary.
3. The method of claim 2 , wherein the predetermined criterion for selectively turning the controller module off comprises the host's glucose falling below the glucose boundary.
4. The method of claim 1 , wherein the selectively turning the controller on or off comprises selectively turning the insulin delivery on when the processed glucose sensor data meets a predetermined criterion relative to the predetermined glucose boundary.
5. The method of claim 4 , wherein the predetermined criterion for selectively turning the controller module on comprises the host's glucose surpassing the glucose boundary.
6. The method of claim 1 , wherein the predetermined glucose boundary comprises a set point.
7. The method of claim 6 , wherein the predetermined glucose boundary comprises more than one set point.
8. The method of claim 7 , wherein the more than one set point comprises a first set point to select the on instruction and a second set point to select the off instruction.
9. The method of claim 1 , wherein the processed glucose sensor data is generated by a continuous analyte sensor.
10. The method of claim 1 , wherein the processed glucose sensor data is generated by one or more auxiliary sensors.
11. The method of claim 1 , further comprising adaptively adjusting the glucose boundary.
12. The method of claim 11 , further comprising requesting validation from a user prior to applying an adaptive adjustment to the glucose boundary.
13. The method of claim 1 , wherein the controlling comprises controlling insulin delivery at a faster rate or a slower rate based on the processed glucose sensor data.
14. A diabetes management system, the system comprising:
a processor comprising a controller module configured to control insulin delivery to a host based on an iterative evaluation of internally derived data relative to a predetermined glucose boundary, wherein the controller module is further configured to selectively turn the controller on or off responsive to the iterative evaluation,
wherein the internally derived data comprise processed glucose data and insulin on-board information, and wherein the interatively evaluating comprises interatively evaluating the insulin on board information.
15. The system of claim 14 , further comprising an insulin delivery device.
16. The system of claim 15 , further comprising a continuous glucose monitor.
17. The system of claim 15 , wherein the controller module comprises a basal controller module.
18. The system of claim 15 , wherein the controller module comprises a bolus controller module.
