Insulin Pump CGM Data Integration on Startup Screen
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ambulatory insulin infusion pumps require users to manually transfer data from continuous glucose monitors (CGM) to the pump, making it cumbersome to determine if insulin adjustments are needed.
Innovation Solution
A portable insulin pump integrates and displays data from a CGM on its startup screen, showing current glucose levels, historical data, and un-metabolized insulin estimates, allowing users to assess if insulin adjustments are necessary without navigating through multiple screens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If CGM data is manually transferred to the pump, then data accuracy is maintained, but user operation complexity increases and time is lost
Solution Approach 1:
The pump system automatically receives and processes CGM data without requiring manual user intervention. The system self-updates its glucose monitoring data through wireless communication with the CGM device, eliminating the need for users to manually transfer data while maintaining data accuracy and reliability.
Solution Approach 2:
The manual mechanical process of data transfer is replaced with an automated wireless communication system. The pump and CGM device establish a wireless data connection that automatically synchronizes glucose monitoring data, replacing the need for physical manual transfer operations.
2Loss of information
If multiple screens are used to display pump and CGM data, then comprehensive information is available, but user time to access information increases
Solution Approach 1:
The pump display integrates and merges both pump operational data and CGM glucose monitoring data into a single unified display interface. This consolidation allows users to access all critical information (insulin delivery status, glucose levels, historical data) without needing to navigate between multiple separate screens or devices.
Solution Approach 2:
The system pre-organizes and pre-displays all critical pump and CGM data on the startup screen before the user needs to access it. By proactively presenting consolidated information immediately upon device activation, the system eliminates the need for users to spend time navigating through multiple menus or screens to find basic data.
3Device complexity
If CGM data is not integrated with the pump, then device simplicity is maintained, but treatment accuracy and timeliness deteriorate
Solution Approach 1:
The pump system is enhanced with multi-functionality to simultaneously serve as both an insulin delivery device and a glucose monitoring integration platform. By incorporating CGM data reception, processing, and display capabilities directly into the pump, the system achieves universal functionality that improves treatment accuracy without requiring separate dedicated monitoring devices.
Data Source
AI summary
A portable insulin pump can integrate and display data from a continuous glucose monitor (CGM) to allow a user to more readily determine whether any interaction with the pump is necessary. Data from the CGM can automatically be transmitted to the pump and can be displayed for user analysis or automatically analyzed to present recommendations to the user based on combined data from the CGM and the pump.
