AED Power Adapter Recognition for Safe Non-Clinical Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automated external defibrillators (AEDs) lack the ability to differentiate between clinical and non-clinical power sources, potentially leading to unsafe or ineffective operation when used outside clinical settings.
Innovation Solution
An automated external defibrillator system that includes a non-clinical power adapter and processor to ensure safe operation in non-clinical settings by disabling external energy delivery, charging to a lower threshold, and enabling internal discharge of stored energy, while maintaining other non-clinical features like diagnostic testing and data transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If AED is designed to deliver therapeutic shock to treat ventricular fibrillation, then life-saving capability is improved, but risk of unsafe operation in non-clinical settings increases
Solution Approach 1:
The system changes the operational parameters of the AED based on the detected power source type. When a non-clinical power source is detected, the system modifies delivery parameters by disabling therapeutic shock delivery while maintaining diagnostic and training functions. This parameter change resolves the contradiction by enabling safe non-clinical operation while preserving life-saving capability when proper clinical power sources are used.
Solution Approach 2:
The power adapter serves as an intermediary component that mediates between the power source and the AED system. It includes a detector that identifies whether the power source is clinical or non-clinical, and communicates this information to the control circuitry. This intermediary enables the system to differentiate between usage contexts and adjust operation accordingly, resolving the safety contradiction.
2Reliability
If AED is configured for clinical use with full functionality, then treatment effectiveness is improved, but device complexity increases
Solution Approach 1:
The system segments functionality based on usage context. Clinical functions (therapeutic shock delivery) are separated from non-clinical functions (diagnostic testing, training). The power adapter detector segments the operational modes, enabling the system to activate only appropriate functions based on the detected power source type. This segmentation reduces unnecessary complexity in non-clinical settings while maintaining full clinical effectiveness when needed.
3Ease of operation
If AED allows operation with any power source, then ease of operation is improved, but safety control deteriorates
Solution Approach 1:
The system performs self-service by automatically detecting the power source type through the power adapter's detector and adjusting its operation accordingly. No manual intervention or user configuration is needed. The system self-regulates to enable or disable specific functions based on the detected power source, maintaining both ease of operation and safety control simultaneously.

AI summary
Some embodiments of the current disclosure are directed toward defibrillation and defibrillation equipment, and more particularly, an automated external defibrillator (AED) and a non-clinical power adapter therefor. In some embodiments, an AED may include an electrical connector to receive a battery pack, at least one capacitor to store energy, an electrotherapy delivery circuit to deliver the energy externally as electrotherapy, at least one discharge circuit to internally discharge energy stored in the capacitor(s), a non-clinical power adapter to be received by the electrical connector, and at least one processor. The processor(s) may determine whether the non-clinical power adapter is electrically coupled to the electrical connector, determine whether the automated external defibrillator recognizes the non-clinical power adapter, and/or enable power to be supplied to the automated external defibrillator from the non-clinical power adapter if the automated external defibrillator recognizes the non-clinical power adapter.
