Minimally burdensome blood glucose management for insulin-requiring diabetes
Some embodiments include burden-free insulin delivery systems and methods. In some embodiments, a method may include receiving previous insulin delivery data at a user device from an insulin pump; receiving estimated glucose data at the user device from a continuous glucose monitor; determining an insulin delivery amount based on the previous insulin delivery data and the estimated glucose data to bring the estimated glucose data closer to a target glucose value without using any user-specific behavioral data physically entered by a user through a user interface of the user device within a previous period of time, the previous period of time being less than six hours; and communicating the insulin delivery amount to the insulin pump.

communicating the insulin delivery amount from the user device to the insulin pump.
2. The method according to claim 1 , wherein the previous insulin delivery data includes the amount of insulin delivered to the user over a period of time.
3. The method according to claim 1 , wherein the insulin delivery data is received from the insulin pump via Bluetooth and/or the estimated glucose data is received from the continuous glucose monitor via Bluetooth.
4. The method according to claim 1 , wherein the user-specific behavioral data comprises data selected from the list consisting of one or more of a mealtime announcement, a meal carbohydrate content estimate, an exercise announcement, and a sleep announcement.
5. The method according to claim 1 , wherein the insulin delivery amount comprises an insulin correction to a basal insulin rate.

8. The glucose management system according to claim 7 , wherein the glucose monitoring device and the insulin pump communicate wirelessly with the controller.
9. The glucose management system according to claim 7 , wherein the glucose monitoring device is a class II insulin pump and/or the glucose monitoring device is a class II integrated continuous glucose monitoring system.
10. The glucose management system according to claim 7 , wherein the controller comprises a mobile device.
11. The glucose management system according to claim 7 , wherein the controller and the insulin pump are part of a single device.
12. The glucose management system according to claim 7 , wherein the user-specific data comprises either user-specific behavioral data or user specific physiological data.
13. The glucose management system according to claim 7 , wherein the user-specific data comprises data selected from the list consisting of one or more of a mealtime announcement, a meal carbohydrate content estimate, an exercise announcement, a sleep announcement; a glucose value, an estimated glucose value, a ketone measurement, an insulin delivery trend, physical activity data, movement data, and exertion data.
14. The glucose management system according to claim 7 ,
wherein the controller wirelessly connects with either or both the glucose monitoring device or the insulin pump;
wherein the controller determines connectivity information regarding the connection between either or both the glucose monitoring device or the insulin pump; and
wherein the controller instructs the user interface to output connectivity information.
15. The glucose management system according to claim 7 ,
wherein the controller determines a fault in the glucose management system; and
wherein the controller instructs the user interface to output a fault indication;
wherein the fault comprises a fault selected from the list consisting of a glucose monitoring device end-of-life fault, a transient fault, a permanent fault, a battery end-of-life fault, a pump fault, an occlusion, a glucose sensor pull-out fault, a controller fault, and a system operation fault.
16. The glucose management system according to claim 7 , wherein the insulin delivery amount comprises an insulin correction to a basal insulin rate.
