Medical Device Interface Segmentation for Guided Treatment Steps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Untrained users face challenges in accurately and efficiently operating complex medical devices, such as AEDs, in high-stress environments due to confusing user interfaces, leading to delayed care for medical emergencies.
Innovation Solution
Enhanced graphical user interfaces for medical devices that selectively activate and deactivate icons based on the operation stage, providing clear instructions through a display with a background color for hidden icons and audio guidance, simplifying the operation for untrained users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If complex medical devices provide comprehensive operation instructions through traditional user interfaces, then the completeness of information is improved, but the ease of operation deteriorates due to interface complexity
Solution Approach 1:
The user interface is segmented into multiple display pages, each showing only the operation instructions relevant to the current stage. The system divides comprehensive instructions into staged segments, preventing information overload while maintaining completeness through sequential presentation.
Solution Approach 2:
The user interface dynamically adapts its content based on the current operation stage. Instructions are activated or deactivated in real-time according to the device's operational state, ensuring users see only relevant information at each moment rather than static comprehensive guides.
2Adaptability or versatility
If medical devices display all available operation icons simultaneously, then the adaptability to different operations is improved, but the device complexity increases leading to user confusion
Solution Approach 1:
Multiple operation icons are segmented across different display pages rather than shown simultaneously. Each page presents a subset of icons relevant to the current operation stage, reducing visual complexity while maintaining access to all functions through sequential navigation.
Solution Approach 2:
Relevant operation icons are extracted and displayed based on the current operational context. Icons unrelated to the current stage are temporarily removed from view, reducing interface complexity while preserving adaptability through context-aware selection.
3Ease of manufacture
If traditional user interfaces provide static operation instructions, then the manufacturing simplicity is improved, but the loss of time increases due to user errors and delays
Solution Approach 1:
The user interface transitions from static to dynamic, automatically updating displayed instructions based on real-time operational state. This dynamic adaptation reduces user errors and delays without requiring complex manual reconfiguration, achieving time savings through automated context-aware display management.

AI summary
An example method includes illuminating, by a screen, a first treatment icon and a pause icon. The first treatment icon corresponds to a command to administer a first treatment to a subject. The pause icon corresponds to an instruction to refrain from administering a second treatment to the subject. The example method further includes de-illuminating, at the screen, a second treatment icon corresponding to an instruction to administer the second treatment to the subject; determining that a physiological parameter of the subject is indicative of a condition by analyzing the physiological parameter; and in response to determining that the physiological parameter of the subject is indicative of the condition: illuminating, at the screen, the first treatment icon; and de-illuminating the pause icon and the second treatment icon. A treatment is administered to the subject in response to detecting a touch signal.
