1. A method comprising:
- determining available insulin delivery segments for a back-fill time based on a correction bolus;
determining a cumulative insulin on board (IOB) based on all the available insulin delivery segments being back-filled;
back-filling a number of the available insulin delivery segments;
adjusting the number of the available insulin delivery segments that are back-filled until one of the cumulative IOB based on the number of back-filled insulin delivery segments is equal to or less than the correction bolus, or the cumulative insulin of the number of back-filled insulin delivery segments is less than the correction bolus; and
adjusting a baseline basal rate based on the back-filled insulin delivery segments, the baseline basal rate used for a diurnal time block related to at least a portion of the back-fill time.

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. Such personalization may include adjusting user specific dosage parameters in response to one or more back-filled time segments associated with a diurnal time block.

1. A method comprising:
-
determining available insulin delivery segments for a back-fill time based on a correction bolus; determining a cumulative insulin on board (IOB) based on all the available insulin delivery segments being back-filled; back-filling a number of the available insulin delivery segments; adjusting the number of the available insulin delivery segments that are back-filled until one of the cumulative IOB based on the number of back-filled insulin delivery segments is equal to or less than the correction bolus, or the cumulative insulin of the number of back-filled insulin delivery segments is less than the correction bolus; and adjusting a baseline basal rate based on the back-filled insulin delivery segments, the baseline basal rate used for a diurnal time block related to at least a portion of the back-fill time. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9)

10. A system comprising:
-
an insulin delivery device configured to deliver insulin via a plurality of insulin delivery actions over a back-fill time prior to a correction bolus, and deliver the correction bolus; and a control device in communication with the insulin delivery device, the control device configured to; obtain an amount of insulin delivered in the correction bolus; determine available insulin delivery segments for the back-fill time based on which of the plurality of insulin delivery actions delivered less than a maximum amount of insulin relative to a baseline basal rate; back-fill a number of the available insulin delivery segments based on an amount of insulin in the correction bolus; and adjust a baseline basal rate based on the back-filled insulin delivery segments, the baseline basal rate used for a diurnal time block related to at least a portion of the back-fill time. - View Dependent Claims (11, 12, 13, 14, 15)
