Abstract
A simplified insulin pump allows diabetics to identify routine patterns in their daily lifestyle that provide a generally accurate typical pattern of activity and meals. An infusion regimen can be programmed into the pump that generally correlates with this typical pattern to provide a viable treatment option for a diabetic without the need for specific and precise matching of insulin to carbohydrate consumption or activity level.
Core Innovation
The invention is an ambulatory infusion pump system that determines that a user will be eating a meal and then causes a delivery mechanism to deliver a meal bolus of insulin of a single fixed amount. The meal bolus is delivered in a single continuous delivery operation in response to the determination that the user will be eating the meal, and the single fixed amount is predetermined without precisely matching the amount of the meal bolus with a number of carbohydrates to be consumed in the meal.
In the described configuration, the processor and associated system components store and manage a recurring meal bolus schedule that provides single fixed insulin amounts at fixed delivery times and/or time windows that correlate with routine lifestyle patterns. The system supports delivering meal boluses for different meal categories, such as breakfast, lunch, and dinner, and can vary the fixed schedules by day type or conditions, such as weekday/weekend or sick/athletic activity, while continuing to avoid precise carbohydrate matching.
The described architecture further includes user interface functionality for meal bolus alerting or announcement and optional user confirmation, confirmation-to-cancel, or modify actions prior to delivery. The system supports delivery of multiple boluses per day and may provide an extended bolus delivery across a time range with in-delivery edit or cancel capability. An alternative implementation integrates meal bolus delivery into an adjusted basal rate using a temporary rate to further reduce user interaction.
Claims Coverage
The partial content identifies two independent claims: an ambulatory infusion pump system claim and a method claim. Both independent claims share the same core inventive concept, and the identified claim families also include refinements such as storage in memory, meal-detection based on user input, delivery automatically after determination, optional user confirmation and modification, and meal-type categories.
Determine meal intent and deliver a single fixed meal bolus without carbohydrate matching
An ambulatory infusion pump system including a reservoir configured to contain insulin, a delivery mechanism configured to deliver insulin from the reservoir to a user, and at least one processor configured to determine that a user will be eating a meal and cause the delivery mechanism to deliver a meal bolus of insulin of a single fixed amount to the user in a single continuous delivery operation in response to determining that the user will be eating the meal, wherein the single fixed amount of the meal bolus is predetermined without precisely matching the amount of the meal bolus with a number of carbohydrates to be consumed in the meal.
Determine meal intent and cause single continuous fixed-amount meal bolus delivery without carbohydrate matching
A method of providing insulin therapy to a user of an ambulatory infusion pump comprising determining with a processor that a user will be eating a meal and causing, with the processor, the ambulatory infusion pump to deliver a meal bolus of insulin of a single fixed amount to the user in a single continuous delivery operation in response to determining that the user will be eating the meal, wherein the single fixed amount of the meal bolus is predetermined without precisely matching the amount of the meal bolus with a number of carbohydrates to be consumed in the meal.
Both independent claims cover meal-intent determination followed by delivery of a meal bolus as a single continuous operation using a single predetermined fixed amount of insulin that is not precisely matched to meal carbohydrate amounts. The claim families further refine the fixed amount, the determination and delivery trigger, and user interaction options such as confirmation and modification, including meal-type categorization like breakfast, lunch, and dinner.
Stated Advantages
Reduces or eliminates the need to count carbohydrates or match insulin precisely to meal carbohydrates/activity.
Documented Applications
Providing insulin therapy for type II diabetes using an ambulatory infusion pump system that delivers recurring fixed-dose meal boluses based on routine lifestyle patterns.
Delivering different fixed meal bolus schedules for multiple meals per day, such as breakfast, lunch, and dinner, and varying schedules by day type, such as weekday/weekend, or conditions, such as sick/athletic activity.
Using optional user interaction features, including alerting or announcement and optional user confirmation, to support delivering fixed-amount meal boluses.
Integrating meal bolus delivery into an adjusted basal rate using a temporary rate to reduce user interaction.
