Insulin Pump Database Segmentation for Carbohydrate Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current insulin delivery systems for diabetic patients are not user-friendly and often result in suboptimal insulin dosages due to the complexity and inaccuracy of inputting nutritional intake data, leading to potential delays in glucose level adjustments.
Innovation Solution
A system that includes a subsystem for controlled insulin delivery, a user input subsystem for nutritional data processing, and a database to calculate and adjust insulin dosages based on specific food items, allowing for precise modification of insulin delivery programs through a mobile device or dedicated device with touch screen and voice input capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the system requires manual calculation and input of total carbohydrate consumption, then the system can process nutritional data, but the process becomes complex and time-consuming for users
Solution Approach 1:
The patent segments the carbohydrate intake tracking into individual food items with pre-defined carbohydrate values stored in a database. Instead of requiring users to manually calculate totals, the system breaks down the process into selecting individual items from a list, automatically summing their carbohydrate content. This segmentation simplifies user interaction while maintaining accurate tracking of nutritional data.
2Measurement precision
If the system requires research and calculation of carbohydrate content for multiple food products, then accurate nutritional data can be obtained, but the time required for input increases significantly
Solution Approach 1:
The patent implements preliminary action by pre-storing carbohydrate content values for numerous food items in a database before use. When a user selects a food item, the system has already have the carbohydrate data ready for immediate retrieval and processing. This eliminates the time-consuming research and calculation steps that would otherwise be required, while ensuring accurate nutritional data is captured.
3Ease of operation
If the system uses rough estimates for carbohydrate content, then data input becomes simpler, but the accuracy of insulin dosage calculations deteriorates
Solution Approach 1:
The patent implements self-service by having the system automatically retrieve and sum carbohydrate values from its database based on user selections. The system serves itself by performing the data aggregation and calculation functions that would otherwise require manual user input. This maintains simplicity for the user while ensuring accurate, precise data is used for insulin dosage calculations.
4Loss of information
If the system requires identification of all food products before meal consumption, then complete nutritional tracking is achieved, but the complexity of the system increases
Solution Approach 1:
The patent uses copying by providing users with a pre-prepared list of food items and their carbohydrate values. Instead of requiring users to create new entries or perform complex lookups, the system offers copies of established food database entries that can be easily selected. This maintains complete nutritional tracking while significantly reducing system complexity and user burden.
Data Source
AI summary
A system for managing administration of insulin to a user includes an infusion pump to effect controlled delivery of insulin A user interface device displays representations of user intake items. A database stores a catalog of intake items. A programmed processing system is programmed with a baseline user insulin delivery program to make a calculation of insulin to be delivered according to the baseline insulin delivery program or according to a modified baseline insulin delivery program based upon user input data. The user provides user input using the user interface application to identify representations of any of the plurality of intake items and the processing system automatically effects delivery of insulin to the user according to the modified baseline insulin delivery program, instead of the baseline insulin delivery program.
