Abstract
Disclosed are a device, system, methods and computer-readable medium products that provide an updated insulin-to-carbohydrate ratio and an updated total daily insulin. The described processes may be used for periodic updating of the insulin-to-carbohydrate ratio and the total daily insulin. The insulin-to-carbohydrate ratio and/or the total may be used in the calculation of new doses of insulin that a drug delivery device may be commanded to deliver to a user.
Claims20
A device, comprising:
- a processor;
- and
- a memory storing programming code, an artificial pancreas application, and operable to store data related to the artificial pancreas application, wherein the programming code and the artificial pancreas application are executable by the processor,
- wherein the processor when executing the artificial pancreas application is operable to control delivery of insulin, and to perform functions, including functions to:
- receive an approximate amount of carbohydrates ingested in a meal;
- determine an amount of insulin onboard in a post prandial time period;
- determine an error factor representing an amount of insulin over or under delivered during the post prandial period;
- determine a difference between the determined amount of insulin onboard and the error factor;
- calculate an updated insulin to carbohydrate ratio based on the determined difference and the approximate amount of carbohydrates ingested;
- and
- modify delivery of insulin based on the updated insulin to carbohydrate ratio.
A non-transient computer readable medium embodied with programming instructions, where the programming instructions when executed by a processor configure the processor to:
- receive an approximate amount of carbohydrates ingested in a meal;
- determine an amount of insulin onboard in a post prandial time period;
- determine an error factor representing an amount of insulin over or under delivered during the post prandial period;
- determine a difference between the determined amount of insulin onboard and the error factor;
- calculate an updated insulin to carbohydrate ratio based on the determined difference and the approximate amount of carbohydrates ingested;
- and
- modify delivery of insulin based on the updated insulin to carbohydrate ratio.
