Interactive Control Panel for Medical Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
External defibrillators pose challenges in providing user-friendly interfaces for different skill levels due to limited space, making it difficult to automate functions for both inexperienced and experienced users during critical treatment situations, especially in emergency cardiac arrests like Ventricular Fibrillation.
Innovation Solution
A medical device with a control panel that can be positioned in multiple modes, exposing different sets of user controls to accommodate various skill levels, allowing interaction with a patient module for treatment and monitoring, and incorporating features like ECG monitoring, automated shock determination, and CPR guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the control panel provides comprehensive controls for experienced users, then the device functionality is complete, but the interface becomes complex and difficult for novice users to operate
Solution Approach 1:
The control panel is segmented into multiple operational modes (automated mode and manual mode) that divide the interface into different functional sets. Novice users interact with the automated mode which presents a simplified interface, while experienced users can switch to manual mode for comprehensive control. This segmentation allows the single control panel to adapt to different user skill levels without requiring multiple physical devices.
2Ease of operation
If the control panel is simplified for novice users, then ease of operation improves, but advanced functions become inaccessible
Solution Approach 1:
The control panel dynamically adapts its interface based on the selected operational mode. When in automated mode, the interface presents simplified controls suitable for novice users. When switched to manual mode, the interface dynamically reveals advanced controls and functions for experienced users. This dynamic reconfiguration allows the same physical control panel to provide appropriate complexity levels for different user needs without permanently limiting any functionality.
3Adaptability or versatility
If multiple control interfaces are provided for different skill levels, then adaptability to user skill levels improves, but device complexity increases due to limited space
Solution Approach 1:
The control panel is designed as a universal interface that performs multiple functions depending on the operational mode selected. The same physical controls serve different purposes in automated mode versus manual mode. This multi-functionality eliminates the need for separate control panels for different skill levels, accommodating novice and experienced users within a single unified device structure despite space constraints.

AI summary
Medical devices and methods in which a user can treat a patient or monitor a parameter of the patient or both may include a housing, a patient module located within the housing that is used for treating the patient, monitoring the patient or both, and a control panel. The control panel is attached to the housing and has a first surface and a second surface and is positionable between a first position and a second position with respect to the housing. The first position exposes a user to a first surface of the control panel and the second position exposes the user to a second surface of the control panel. A first set of user controls are located on one or the other of the first surface and the second surface and are structured to allow the user to interact with the patient module.
