Abstract
The disclosed examples provide techniques and devices for determining a daily basal profile or an adjusted basal need for a drug based on a collection of data that is filtered and processed. A controller may be configured to evaluate a history of drug delivery in both basal and bolus dosages and generate a daily basal profile or an adjusted basal need that is a time dependent that may be used to schedule basal dosages of a drug that more closely addresses a user's drug needs over the course of a time period, such as a day, week or the like.
Claims20
A drug delivery device comprising:
- a controller;
- a drug delivery mechanism communicatively coupled to the controller;
- and
- a memory configured to store a drug delivery history and instructions that, when executed by the controller, configure the drug delivery device to:
- retrieve the drug delivery history, the drug delivery history comprising a plurality of basal drug delivery dosages of a drug delivered over a period of time, wherein the period of time is partitioned into a plurality of intervals, and the drug delivery history includes, for each basal drug delivery dosage, an amount of drug delivered and a corresponding delivery time within a respective interval;
- evaluate the basal drug delivery dosages within each interval to determine an interval profile for each of the intervals within the period of time;
- determine, from the interval profiles across the plurality of intervals, an average interval profile comprising a series of average basal drug delivery dosages, each having a corresponding average delivery time;
- consolidate average basal delivery dosages meeting a drug amount similarity criterion and a delivery time similarity criterion relative to other average basal drug delivery dosages in the series to generate an updated basal delivery dosage and a corresponding updated delivery time;
- modify a basal drug delivery schedule based on the updated basal delivery dosage and the updated delivery time;
- and
- cause delivery of updated basal delivery dosages according to the modified basal drug delivery schedule via the drug delivery mechanism.

A method comprising:
- retrieving, by a computing component of a drug delivery system from a storage medium communicatively coupled to the computing component, a drug delivery history comprising a plurality of basal drug delivery dosages of a drug delivered over a period of time, wherein the period of time is partitioned into a plurality of intervals, and the drug delivery history includes, for each basal drug delivery dosage, an amount of drug delivered and a corresponding delivery time within a respective interval;
- evaluating the basal drug delivery dosages within each interval to determine an interval profile for each of the intervals within the period of time;
- determining, from the interval profiles across the plurality of intervals, an average interval profile comprising a series of average basal drug delivery dosages, each having a corresponding average delivery time;
- consolidating average basal delivery dosages meeting a drug amount similarity criterion and a delivery time similarity criterion relative to other average basal drug delivery dosages in the series to generate an updated basal delivery dosage and a corresponding updated delivery time;
- modifying a basal drug delivery schedule based on the updated basal delivery dosage and the updated delivery time;
- and
- causing delivery of updated basal delivery dosages according to the modified basal drug delivery schedule via a drug delivery mechanism.
