Machine learning in an artificial pancreas

A system comprising:

• an artificial pancreas controller to:
• establish a first wireless connection to a wearable glucose monitoring device worn by a user and a second wireless connection to an insulin delivery system worn by the user;
• receive, via the first wireless connection, an initial glucose measurement provided by the wearable glucose monitoring device worn by the user;
• receive, via a user interface, user input describing an amount of carbohydrates to be consumed by the user as part of a meal;
• monitor glucose measurements provided by the wearable glucose monitoring device worn by the user after the meal to detect a peak glucose measurement;
• and
• determine a carbohydrate-to-glucose ratio for the user based on the initial glucose measurement, the peak glucose measurement, and the amount of carbohydrates consumed by the user;
• and
• a pump control manager to control the insulin delivery system to deliver bolus insulin doses to the user based at least in part on the carbohydrate-to-glucose ratio.

One or more computer-readable storage media having instructions stored thereon that are executable by one or more processors to perform operations comprising:

• establishing a first wireless connection to a wearable glucose monitoring device worn by a user and a second wireless connection to an insulin delivery system worn by the user;
• receiving, via the first wireless connection, an initial glucose measurement provided by the wearable glucose monitoring device worn by the user;
• receiving, via a user interface, user input describing an amount of carbohydrates to be consumed by the user as part of a meal;
• monitoring glucose measurements provided by the wearable glucose monitoring device worn by the user after the meal to detect a peak glucose measurement;
• determining a carbohydrate-to-glucose ratio for the user based on the initial glucose measurement, the peak glucose measurement, and the amount of carbohydrates consumed by the user;
• and
• controlling the insulin delivery system to deliver bolus insulin doses to the user based at least in part on the carbohydrate-to-glucose ratio.

An apparatus comprising:

• an establishing means for establishing a first wireless connection to a wearable glucose monitoring device worn by a user and a second wireless connection to an insulin delivery system worn by the user;
• a first receiving means for receiving, via the first wireless connection, an initial glucose measurement provided by the wearable glucose monitoring device worn by the user;
• a second receiving means for receiving, via a user interface, user input describing an amount of carbohydrates to be consumed by the user as part of a meal;
• a monitoring means for monitoring glucose measurements provided by the wearable glucose monitoring device worn by the user after the meal to detect a peak glucose measurement;
• a determining means for determining a carbohydrate-to-glucose ratio for the user based on the initial glucose measurement, the peak glucose measurement, and the amount of carbohydrates consumed by the user;
• and
• a controlling means for controlling the insulin delivery system to deliver bolus insulin doses to the user based at least in part on the carbohydrate-to-glucose ratio.
