Medical Device Interface Segmentation for Infusion Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medical devices, particularly infusion pumps, often present clinicians with overwhelming information, making them difficult to navigate and program, which can lead to clinical errors and inefficiencies in patient care.
Innovation Solution
A medical device with a touch screen graphical user interface that allows for easy navigation and programming, enabling clinicians to configure infusion data, change clinical care areas without interrupting ongoing infusions, and add additional volume to infusions without stopping them, featuring quick titration buttons and customizable alarm features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If comprehensive patient and treatment information is displayed on the graphical user interface, then clinician efficiency is improved, but the interface becomes overwhelming and difficult to navigate
Solution Approach 1:
The graphical user interface is segmented into multiple navigable screens or views, each displaying specific subsets of patient and treatment information. This allows comprehensive information to be organized into manageable sections that can be accessed sequentially or simultaneously without overwhelming the clinician.
Solution Approach 2:
The interface utilizes multiple dimensions of display organization including hierarchical menus, tabbed interfaces, or layered information panels that allow clinicians to navigate through information vertically and horizontally rather than presenting all data in a single flat view.
2Productivity
If the medical device allows flexible programming of infusion parameters, then clinician efficiency is improved, but the device complexity increases
Solution Approach 1:
The device includes pre-configured infusion protocols and parameter sets that can be selected and modified as needed. Common infusion scenarios are prepared in advance with default settings, allowing clinicians to quickly program infusions by making minimal adjustments rather than configuring every parameter from scratch.
Solution Approach 2:
The programming interface dynamically adapts to the clinician's needs by displaying only relevant parameters based on the selected infusion type and current device state. Optional parameters are hidden or grayed out unless needed, reducing the apparent complexity while maintaining full functionality.
3Reliability
If the device requires cassette in place for programming, then device reliability is improved, but the ease of operation is reduced
Solution Approach 1:
The device allows partial programming operations to be performed without a cassette installed, enabling clinicians to configure basic parameters, select protocols, or prepare infusion settings in advance. The system validates and completes the programming process when the cassette is installed, ensuring reliability while providing operational flexibility.
