Universal Defibrillator Electrode Dual Graphics Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Automated External Defibrillators (AEDs) are primarily designed for adult use and lack effective guidance for electrode placement on pediatric patients, leading to potential confusion and delays in emergency situations, as they often feature graphics that restrict placement guidance to either adult or pediatric patients, causing issues when a universal electrode is used across different age groups.
Innovation Solution
The development of universal electrodes with dual graphics for both adult and pediatric patients, featuring intuitive and distinct sizing, orientation, and coloring to guide correct placement without causing confusion, along with a mode switch for energy adjustments, ensures accurate placement and energy delivery for all ages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If AEDs are designed with graphics for adult patients only, then the device is simple and intuitive for adult use, but it lacks guidance for pediatric patients causing confusion and delays
Solution Approach 1:
The electrode pad graphics are designed to serve multiple functions by including both adult and pediatric body images on the same pad. The graphic display shows different body images for different patient types, allowing the same electrode pad to provide appropriate guidance for both adult and pediatric patients without requiring separate pads or complex switching mechanisms.
2Measurement precision
If AEDs include controls for energy adjustments based on body mass, then pediatric treatment accuracy is improved, but device complexity and cost increase
Solution Approach 1:
The AED system performs self-service by automatically detecting patient type (adult or pediatric) and selecting the appropriate energy level and treatment protocol without requiring manual input from the operator. The device autonomously adjusts treatment parameters based on the detected patient category, eliminating the need for complex controls while maintaining pediatric treatment accuracy.
3Manufacturing precision
If separate electrode pads are provided for adult and pediatric patients, then placement guidance is accurate for each age group, but device complexity and operator decision-making increase during emergencies
Solution Approach 1:
A single universal electrode pad design incorporates graphics suitable for both adult and pediatric patients. The pad includes multiple body images and placement indicators that can guide correct electrode placement for different patient types, eliminating the need for separate adult and pediatric pads while maintaining placement accuracy for both age groups.
4Reliability
If the AED provides detailed energy adjustments for pediatric patients, then treatment effectiveness is improved, but the number of decisions the operator must make increases during time-critical situations
Solution Approach 1:
The AED automatically determines the appropriate energy level and treatment protocol by detecting patient type and selecting pre-programmed pediatric protocols. This self-service capability eliminates the need for operators to manually adjust energy settings or make complex decisions about pediatric treatment parameters, reducing the decision-making burden while maintaining treatment effectiveness through automated selection of evidence-based protocols.

AI summary
An electrode pad (110, 210) for a defibrillator has an improved graphic indication for placement of the pad on a patient during a rescue. The graphic indication may include both of an adult figure and a pediatric figure showing the placement of the electrode pad. Thus, the graphic figures assist the rescuer in placing the electrode pad for both adult and pediatric patients.
