AED Pad Placement Guidance via Progressive State Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Automatic External Defibrillators (AEDs) lack the ability to sense intermediate steps during pad deployment and attachment, leading to operator errors due to lack of specific guidance, especially under stressful conditions, resulting in inconsistent and inaccurate pad placement.
Innovation Solution
An AED that senses progressive states of pad deployment and attachment, providing specific operator prompts to ensure accurate and consistent pad placement, including visual guidance through picture prompts and error correction mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If existing AEDs provide only initial voice prompts without sensing intermediate steps, then the device complexity is reduced, but pad placement accuracy and operator guidance deteriorate
Solution Approach 1:
The AED senses intermediate steps during pad deployment and attachment, providing real-time feedback to the operator through specific guidance prompts. The system detects when pads are removed from packaging, when they are attached to the patient, and provides corrective guidance if placement is incorrect, thereby improving pad placement accuracy without requiring complex manual intervention.
Solution Approach 2:
The AED automatically senses the state of pad deployment and attachment, eliminating the need for operators to manually report each step. The system self-monitors the deployment process and autonomously provides guidance prompts, reducing the burden on operators while maintaining high placement accuracy.
2Productivity
If operators perform detailed skilled operations without specific guidance, then the ease of operation is reduced, but the AED can proceed to ECG analysis, resulting in inconsistent pad placement and variable time intervals
Solution Approach 1:
The AED divides the pad deployment process into distinct sequential phases, sensing each intermediate step and providing targeted guidance for each phase. This segmentation allows operators to complete each step with confidence while maintaining consistent overall timing, as the system tracks progress through discrete milestones rather than requiring continuous skilled judgment.
Solution Approach 2:
The system provides real-time feedback prompts at each phase of pad deployment, guiding operators through the process and ensuring consistent time intervals. The feedback mechanism ensures that operators know exactly what to do next, eliminating variability in completion time while maintaining ease of operation under stress.
3Reliability
If untrained operators perform tasks under extreme stress without step-by-step guidance, then the reliability is reduced due to operator error, but providing continuous guidance would increase device complexity
Solution Approach 1:
The AED automatically monitors the pad deployment process and provides guidance without requiring operator input or manual reporting. The system self-assesses the state of pad attachment and autonomously provides corrective guidance, significantly improving reliability for untrained operators under stress without requiring complex interaction protocols.
Solution Approach 2:
The system provides continuous feedback prompts that guide operators through each step of pad deployment, improving reliability by preventing common errors. The feedback mechanism is automatically triggered by sensed intermediate steps, providing timely guidance without requiring complex user input or increasing operational complexity.

AI summary
A method for operating an automatic external defibrillator (AED) prompts an operator about proper operation of the automatic external defibrillator and placement of the electrodes to ensure rapid and proper operation. Depending upon a state of a pad storage compartment, upon activation the AED issues an initial prompt, pauses after the initial prompt and then issues a second prompt. The AED also determines whether the pads have been removed from a liner and if so, issues a pad application prompt. The AED next determines whether both pads have been placed and if so, analyzes an impedance signal and if the impedance signal is erratic, issues a pad correction prompt. The AED also issues the pad correction prompt if the pads are removed from the liner but never go on the patient.
