System and method for adjusting insulin delivery
The embodiments described herein may relate to methods and systems for adjusting insulin delivery. Some methods and systems may be configured to adjust insulin delivery to personalize automated insulin delivery for a person with diabetes. Some methods and systems may be configured to adjust insulin delivery to a person with diabetes according to one or more conditions of an insulin delivery device. Some methods and systems may be configured to enable a lock-out mode where adjustment to insulin delivery to personalize automated insulin delivery is restricted.
1. A diabetes management system, comprising:
a first disposable insulin delivery device configured to deliver insulin to a user having diabetes; and
a reusable control unit adapted to be reversibly connected to the first disposable insulin delivery device,
wherein the system is configured to:
determine a shelf-life risk score for undelivered insulin within the first disposable insulin delivery device; and
responsive to the shelf-life risk score exceeding a threshold, enabling a lock-out mode for locking out a personalization of one or more user-specific dosage parameters until the reusable control unit is reversibly connected to a second disposable insulin delivery device containing fresh insulin.
2. The diabetes management system of claim 1 , wherein the shelf-life risk score is at least based on an age of the undelivered insulin.
3. The diabetes management system of claim 1 , wherein the shelf-life risk score is based at least in part on blood glucose data following a delivery of the insulin in the first disposable insulin delivery device.
4. The diabetes management system of claim 1 , wherein the reusable control unit controls the first disposable insulin delivery device or the second disposable insulin delivery device to:
deliver insulin at a first point in time according to a first insulin delivery action of a first series of insulin delivery actions of a first insulin delivery profile, the first series of insulin delivery actions including at least one action that includes delivering insulin at a rate larger than a baseline basal insulin rate; and
deliver insulin at a second point in time according to a first insulin delivery action of a second series of insulin delivery actions of a second insulin delivery profile, the second series of insulin delivery actions including delivering insulin at the rate larger than the baseline basal insulin rate,
wherein the shelf-life risk score is further based on a number of times insulin is delivered at the rate larger than the baseline basal insulin rate exceeding a threshold.
5. The diabetes management system of claim 1 , further comprising a mobile application of a smartphone in communication with the reusable control unit.
6. The diabetes management system of claim 5 , wherein the mobile application is configured to display insulin delivery times.
7. The diabetes management system of claim 5 , wherein the mobile application is configured to track an amount of undelivered insulin within the first disposable insulin delivery device.
8. The diabetes management system of claim 5 , wherein the mobile application is configured to determine a time of each insulin delivery action of each of the first disposable insulin delivery device and the second disposable insulin delivery device.
9. A method comprising:
determining a shelf-life risk score for undelivered insulin within a first disposable insulin delivery device; and
locking-out a personalization of one or more user-specific dosage parameters for a user responsive to the shelf-life risk score exceeding a threshold,
wherein the locking-out the personalization of at least one of the one or more user-specific dosage parameters enables a second disposable insulin delivery device to deliver fresh insulin.
10. The method of claim 9 , wherein the shelf-life risk score is at least based on an age of the undelivered insulin in the first disposable insulin delivery device.
11. The method of claim 9 , further comprising tracking one or more insulin delivery times for each of the first insulin delivery device and the second insulin delivery device.
12. The method of claim 11 , further comprising displaying the insulin delivery times on a mobile application in wireless communication with a reusable control unit, the reusable control unit being reversibly connectable to each of the first and the second disposable insulin delivery devices.
13. The method of claim 12 , wherein the mobile application determines the shelf-life risk score based at least in part on blood glucose data that the mobile application receives from a blood glucose sensor for time periods after a delivery of insulin.
14. The method of claim 9 , further comprising:
delivering insulin at a first point in time according to a first insulin delivery action of a first series of insulin delivery actions of a first insulin delivery profile, the first series of insulin delivery actions including at least one action that includes delivering insulin at a rate larger than a baseline basal insulin rate; and
delivering insulin at a second point in time according to a first insulin delivery action of a second series of insulin delivery actions of a second insulin delivery profile, the second series of insulin delivery actions including delivering insulin at the rate larger than the baseline basal insulin rate;
wherein the shelf-life risk score is further based on a number of times insulin is delivered at the rate larger than the baseline basal rate exceeding a threshold.
15. The method of claim 9 , further comprising generating a message that the shelf-life risk score has exceeded the threshold.
