AED Non-Clinical Power Adapter for Clinical Battery Readiness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automated external defibrillators (AEDs) face challenges in managing power supply, particularly when non-clinical power adapters are used, which can lead to unintended energy delivery during non-clinical operations, depleting the battery pack and risking clinical readiness.
Innovation Solution
The AED system incorporates a non-clinical power adapter that connects to the AED, allowing it to operate in a non-clinical mode by disabling electrotherapy delivery, charging capacitors to a safe threshold, and discharging energy internally, while maintaining other non-clinical functions without depleting the primary battery pack.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a non-clinical power adapter is used to power the AED during non-clinical operations, then the AED can perform diagnostic testing and training functions, but the battery pack may be depleted and clinical readiness is compromised
Solution Approach 1:
The power supply system is segmented into two independent sources: a battery pack dedicated to clinical operations and a non-clinical power adapter for non-clinical operations. The system includes a power supply selector that allows operators to choose which power source to use, ensuring that non-clinical functions do not deplete the battery pack needed for clinical readiness
Solution Approach 2:
A power supply selector acts as an intermediary component between the battery pack, non-clinical power adapter, and the AED's internal systems. This selector mediates power distribution by routing power from the appropriate source based on the operational mode, preventing unintended depletion of the battery pack during non-clinical operations
2Ease of operation
If the AED allows unrestricted power delivery during non-clinical mode, then non-clinical functions can operate freely, but unintended electrotherapy delivery may occur causing harmful effects
Solution Approach 1:
The system applies preliminary anti-action by implementing preventive measures before unintended electrotherapy can occur. The power supply selector is configured to automatically prevent electrotherapy delivery when non-clinical power adapter is detected, and the system provides warnings or requires confirmation before allowing any energy delivery, thus preventing harmful effects before they can happen
Solution Approach 2:
The system incorporates feedback mechanisms that continuously monitor the operational mode and power source status. When the non-clinical power adapter is connected, the system provides feedback through warnings or status indicators to alert operators that electrotherapy is restricted, and only allows energy delivery after explicit confirmation, thereby preventing unintended harmful delivery

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution ensures the AED's battery pack remains ready for clinical use by preserving energy, preventing inadvertent electrotherapy delivery, and enabling non-clinical operations like diagnostic testing and training without battery depletion.

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.
