Abstract

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.

First claim

What is claimed is:

1. An apparatus, comprising:
an insulin delivery device; and
a controller in communication with the insulin delivery device to control provision of insulin to a person with diabetes via the insulin delivery device,
wherein the controller is configured to:
determine a shelf-life risk score for insulin within the insulin delivery device; and
at least partially responsive to the determined 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 detection of new insulin within the insulin delivery device.

2. The apparatus of claim 1 , wherein the shelf-life risk score is at least partially based on an age of the undelivered insulin.

3. The apparatus of claim 1 , wherein the shelf-life risk score is at least partially based on blood glucose data following a delivery of the insulin in the insulin delivery device.

4. The apparatus of claim 1 , wherein the controller is configured to control the 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 at least partially based on a number of times insulin is delivered at the rate larger than the baseline basal insulin rate exceeding a threshold.

5. The apparatus of claim 1 , comprising a mobile application of a smartphone in communication with a reusable control unit.

6. The apparatus of claim 5 , wherein the mobile application is configured to display insulin delivery times.

7. The apparatus of claim 5 , wherein the mobile application is configured to track an amount of undelivered insulin within the insulin delivery device.

8. The apparatus of claim 5 , wherein the mobile application is configured to determine a time of each insulin delivery action of each of the insulin delivery device and a further insulin delivery device.

9. A method, comprising:
determining a shelf-life risk score for insulin within an 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 until detection of new insulin within the insulin delivery device.

10. The method of claim 9 , wherein the shelf-life risk score is at least partially based on an age of the undelivered insulin in the insulin delivery device.

11. The method of claim 9 , comprising tracking one or more insulin delivery times for each of the insulin delivery device and a further insulin delivery device.

12. The method of claim 11 , 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 further 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 , 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 insulin rate exceeding a threshold.

15. The method of claim 9 , comprising generating a message that the shelf-life risk score has exceeded the threshold.
