Defibrillator Electrode Orientation Detection for Energy Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing external defibrillators require rescuers to adjust settings for different patient types, such as pediatric or geriatric patients, which increases the delay in administering appropriate electrical shocks due to the need for parameter input and orientation adjustments, potentially leading to inappropriate energy levels being administered.
Innovation Solution
An external defibrillator with a defibrillation port that can accommodate multiple orientations for electrode connections, including adult and pediatric settings, equipped with an orientation detection device to automatically adjust the energy level and provide user feedback, allowing the same set of electrodes to be used across different patient types without requiring manual adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual adjustment of defibrillator settings is required for different patient types, then appropriate energy levels can be delivered, but the time to administer defibrillation increases
Solution Approach 1:
The defibrillator automatically detects patient type through the orientation of the electrode pad connector and self-adjusts the energy level without requiring manual intervention from the rescuer. The system serves itself by using the physical orientation information to automatically configure the appropriate defibrillation parameters.
Solution Approach 2:
The defibrillator changes the energy level parameter automatically based on the detected patient type. When the electrode pad connector is oriented in a first direction indicating a pediatric patient, the system changes the energy level to a lower value appropriate for children, whereas a second direction indicates an adult patient and triggers a higher energy level.
2Adaptability or versatility
If multiple electrode sets are provided for different patient types, then appropriate treatment can be given to all patient types, but device complexity and preparation time increase
Solution Approach 1:
A single set of electrodes with a multi-position connector can be used for both pediatric and adult patients. The connector can be oriented in different directions to indicate the patient type, allowing one electrode set to serve multiple functions across different patient populations without requiring separate electrode sets for each type.
3Reliability
If rescuers must manually input patient parameters, then accurate energy level selection is possible, but the complexity of operation increases
Solution Approach 1:
The defibrillator automatically determines the patient type and selects the appropriate energy level without requiring the rescuer to manually input any parameters. The system uses the orientation of the electrode pad connector as the input signal and automatically processes this information to configure the correct defibrillation parameters.
Solution Approach 2:
The manual mechanical process of selecting and inputting patient parameters is replaced by an automatic detection system that reads the orientation of the electrode pad connector and electronically adjusts the energy level. This substitution eliminates the need for manual parameter entry while maintaining accurate energy level selection.

AI summary
Embodiments of the present concept are directed to external defibrillators that include an electrode connection port having multiple connection options, and include a detection device to determine an electrode connection configuration so as to provide an appropriate electrical shock to a patient. The detection device detects the electrode connection configuration of a plug connector for connected electrodes to determine if the plug connector is in an adult orientation or a pediatric orientation. The external defibrillator is configured to a deliver an electrical shock with less energy when the pediatric orientation is detected rather than the adult orientation.
