Insulin Pen Dose Guidance With Glucose-Linked Therapy Recommendations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
PWDs face challenges in accurately determining insulin doses due to cognitive burden, human error, and improper dosing with existing insulin delivery systems, which can lead to hyperglycemia or hypoglycemia.
Innovation Solution
A diabetes management system with a user interface that simplifies data entry and provides therapy recommendations using a pen cap accessory or smart insulin delivery devices, incorporating blood glucose data, meal size estimation, and user-specific parameters to minimize manual calculations and errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If PWDs manually calculate and self-administer insulin doses using traditional insulin pens and blood glucose meters, then they maintain independence in self-care, but they face cognitive burden and human error leading to improper dosing
Solution Approach 1:
The system enables self-service by allowing the insulin pen itself to automatically calculate and guide dosing decisions. The pen integrates sensors that detect blood glucose levels and automatically compute the required insulin dose based on stored algorithms and patient-specific parameters, eliminating the need for manual calculation while maintaining patient independence in self-administration
Solution Approach 2:
The patent replaces the mechanical calculation process (manual math and decision-making) with an electronic system embedded in the insulin pen. The device uses electronic sensors, processors, and memory to automatically determine dosing parameters, substituting the human cognitive process with an automated electronic decision-support system that reduces errors and cognitive burden
2Reliability
If PWDs plan insulin injections in advance based on basal requirements and external factors, then they can prepare for daily therapy, but they still experience dosing errors such as skipping doses, double dosing, or wrong amounts
Solution Approach 1:
The system implements feedback by continuously monitoring blood glucose levels through integrated sensors and using this real-time data to adjust and verify insulin dosing decisions. The device provides feedback to the patient about detected dosing events, glucose levels, and recommended actions, creating a closed-loop system that reduces dosing errors by constantly comparing actual conditions against therapy goals
Solution Approach 2:
The insulin pen is designed as a multi-functional device that combines insulin delivery with glucose sensing, dose calculation, memory storage for therapy parameters, and user interface capabilities. This universal device replaces multiple separate tools (glucose meter, calculator, therapy planner) with a single integrated system that manages the entire therapy process, reducing complexity rather than increasing it
3Reliability
If bolus calculators require manual entry of meal data and mental evaluation of meal constituents, then they can provide insulin dosage recommendations, but they burden the user with additional mental tasks and data entry
Solution Approach 1:
The system enables the insulin pen to automatically detect and process meal-related information through integrated sensors and algorithms. The device self-determines dosing parameters by analyzing glucose data patterns and stored patient parameters without requiring the user to manually evaluate meal constituents or perform mental calculations, thereby reducing user burden while maintaining accurate dosage recommendations
