Insulin Bolus Scheduling With Delay and Rescheduling Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automated insulin delivery devices only allow immediate delivery of insulin boluses, which can be inconvenient for users in certain situations, and may lead to improper timing or forgetting of insulin boluses, resulting in hyperglycemia or hypoglycemia.
Innovation Solution
A computing device enables users to schedule medicament bolus deliveries, such as insulin, for future dates and times, allowing delay, rescheduling, or cancellation, and provides reminders and confirmation options through user interfaces on devices like smartphones and smartwatches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If immediate delivery of insulin boluses is implemented, then the device can quickly respond to glucose level changes, but users may forget to deliver insulin or experience improper timing resulting in hyperglycemia or hypoglycemia
Solution Approach 1:
The system allows users to schedule insulin bolus deliveries in advance for future dates and times. Users can pre-arrange multiple bolus deliveries ahead of time, and the system automatically executes them at the scheduled moments, eliminating the need for manual intervention at the moment of delivery and preventing forgotten or mistimed doses.
2Reliability
If automated scheduling of future insulin deliveries is enabled, then users can schedule boluses ahead of time avoiding hyperglycemia or hypoglycemia, but the device complexity increases with additional scheduling functions
Solution Approach 1:
The insulin delivery device is enhanced with multi-functionality to include both immediate bolus delivery and scheduled future bolus delivery capabilities. The same device hardware and user interface handle both immediate and scheduled deliveries, allowing a single device to serve multiple functions without requiring separate specialized systems.
Solution Approach 2:
The system automatically manages scheduled insulin deliveries without requiring continuous user intervention. Once users set up their scheduling preferences and parameters, the system autonomously determines appropriate delivery times and executes boluses automatically, reducing the burden on users while maintaining accurate timing.
3Ease of operation
If users are required to manually determine and execute insulin bolus timing and dosage, then the device operation remains simple, but many diabetic patients experience less than optimal outcomes due to inaccurate timing and execution
Solution Approach 1:
The system incorporates feedback mechanisms where users can review their scheduled bolus deliveries, modify timing and dosage parameters based on glucose monitoring data, and receive notifications about upcoming deliveries. This allows users to verify and adjust the accuracy of scheduled deliveries while maintaining the simplicity of automatic execution.

AI summary
Exemplary embodiments may enable a user to schedule medicament bolus deliveries, such as insulin boluses, for future dates and times. The exemplary embodiments may provide the ability to delay a scheduled medicament bolus delivery by short periods of time. The user may reschedule a scheduled medicament bolus delivery by entering a new date and/or time for the medicament bolus delivery. Still further, a user may cancel a scheduled medicament bolus delivery. In addition, exemplary embodiments may enable multiple medicament bolus deliveries to be viewed and managed.
