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:
receiving sensor data generated by a continuous glucose monitoring device, wherein the sensor data is indicative of glucose concentration;
calculating an insulin therapy instruction based on the sensor data, using a controller module of a processor;
comparing the determined insulin therapy instruction to one or more criteria;
constraining the determined insulin therapy instruction if the insulin therapy instruction fails the one or more criteria; and
providing the constrained insulin therapy instruction if the insulin therapy instruction fails the one or more criteria wherein the one or more criteria comprises a predetermined basal profile comprising a schedule of one or more time blocks, wherein each time block is associated with a maximum insulin delivery rate.
2. The method of claim 1 , further comprising delivering the constrained insulin therapy instruction using an insulin delivery device.
3. The method of claim 1 , further comprising prompting a user to validate the determined insulin therapy instruction or the constrained insulin therapy instruction.
4. The method of claim 1 , wherein the determined insulin therapy instruction fails the one or more criteria if the insulin therapy instruction exceeds the maximum insulin delivery rate for the current time block.
5. The method of claim 4 , wherein the constraining comprises adjusting the insulin delivery rate of the determined insulin therapy to no more than the maximum delivery rate associated with a time block of the basal profile, whereby the constrained insulin therapy instruction is obtained.
6. The method of claim 1 , wherein the one or more criteria comprises a predetermined bolus constraint.
7. The method of claim 6 , wherein one or more criteria comprises two or more bolus constraints.
8. The method of claim 7 , wherein the two or more constraints are associated with different types of meals and/or with different events.
9. The method of claim 6 , wherein the bolus constraint is engaged by at least one of pressing a button or key, actuating a switch or selecting from a menu.
10. A system for diabetes management, the system comprising:
a processor comprising a controller module configured to calculate an insulin therapy instruction based on the sensor data generated by a continuous glucose monitoring device, wherein the sensor data is indicative of glucose concentration, wherein the controller module is configured to compare the determined insulin therapy instruction to one or more criteria, constrain the determined insulin therapy instruction if the insulin therapy instruction fails the one or more criteria, and provide the constrained insulin therapy instruction if the insulin therapy instruction fails the one or more criteria wherein the one or more criteria comprises a predetermined basal profile comprising a schedule of one or more time blocks, wherein each time block is associated with a maximum insulin delivery rate.
11. The system of claim 10 , further comprising an insulin delivery device for delivering the constrained insulin therapy instruction.
12. The system of claim 10 , wherein the processor is configured to prompt a user to validate the determined insulin therapy instruction or the constrained therapy instruction.
13. The system of claim 10 , wherein the determined insulin therapy instruction fails the one or more criteria if the insulin therapy instruction exceeds the maximum insulin delivery rate for the current time block.
14. The system of claim 13 , wherein the processor module is configured to constrain by adjusting the insulin delivery rate of the determined insulin therapy to no more than the maximum delivery rate associated with a time block of the basal profile, whereby the constrained insulin therapy instruction is obtained.
15. The system of claim 10 , wherein the one or more criteria comprises a predetermined bolus constraint.
16. The system of claim 15 , wherein one or more criteria comprises two or more bolus constraints.
17. The system of claim 16 , wherein the two or more constraints are associated with different types of meals and/or with different events.
18. The system of claim 15 , wherein the bolus constraint is configured to be engaged by at least one of pressing a button or key, actuating a switch or selecting from a menu.
