Impedance-Monitored Defibrillation Insulation for Rescuer Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing defibrillation systems pose a safety risk to rescuers due to inadequate insulation and potential electrical shocks during cardiopulmonary resuscitation, as conventional barriers are ineffective in dynamic and fluid-rich environments, leading to interruptions in chest compressions and reduced resuscitation efficacy.
Innovation Solution
An electrical safety system with an impedance measurement device that monitors insulation integrity by measuring impedance across a range of frequencies, providing real-time feedback to prevent electrical shocks by detecting low impedance conditions and preventing shock delivery when unsafe conditions are detected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional insulated barriers are used during defibrillation, then rescuer protection is provided, but the barriers become ineffective due to fluids, body movement, and rescuer shifting
Solution Approach 1:
The system continuously monitors impedance between the patient and ground to detect changes in insulation effectiveness. When impedance drops below a threshold indicating compromised insulation, the system provides feedback by preventing shock delivery or alerting the operator, thereby maintaining rescuer safety despite barrier movement or fluid contamination
Solution Approach 2:
The patent replaces reliance on mechanical physical barriers with an electrical monitoring system that uses impedance measurement to detect insulation failures. This substitution allows the system to sense and respond to insulation degradation without requiring perfect physical barrier maintenance
2Reliability
If rescuers avoid contact with the patient during shock delivery, then rescuer safety is ensured, but chest compressions are interrupted for long periods
Solution Approach 1:
The impedance monitoring system provides real-time feedback on insulation status, allowing the system to determine when it is safe to deliver shocks during continuous compressions. This feedback mechanism enables uninterrupted CPR by dynamically assessing safety conditions rather than requiring fixed safety intervals
Solution Approach 2:
The system transitions from static safety protocols (fixed interruptions) to dynamic safety assessment by continuously measuring impedance. This allows the shock delivery timing to adapt to real-time insulation conditions, enabling compressions to proceed without predetermined interruptions
3Reliability
If fixed, semi-permanent barriers are installed, then protection against electrical power is provided, but installation is not feasible for power line workers with varying locations
Solution Approach 1:
The patent replaces fixed physical barriers with a portable electrical monitoring system that measures impedance to assess insulation effectiveness. This system can be deployed at any location without installation, providing adaptable electrical protection for power line workers in varying work environments
Solution Approach 2:
The monitoring system automatically assesses insulation conditions without requiring manual inspection or setup. The worker simply needs to be in proximity to the power lines, and the system self-evaluates the insulation status, providing protection that adapts to any location without pre-installation
4Measurement precision
If impedance measurement is performed at multiple frequencies, then detection accuracy is improved, but device complexity increases
Solution Approach 1:
The system measures impedance at multiple frequencies to detect different aspects of insulation degradation. By varying the frequency parameter, the system can distinguish between different types of insulation failures and environmental conditions, improving detection accuracy without requiring complex hardware modifications

AI summary
Technologies are disclosed herein for a low impedance detection system. The detection system includes an electrical insulation and an impedance measurement device. The impedance measurement device can be used to test the impedance of the system when the barrier is placed between the user of the barrier and a source of electrical power. In a defibrillation system, a rescuer can place the barrier over the patient. An electrical power source can deliver electrical shocks to the patient. The impedance measurement device can monitor impedances of the system across various frequencies to detect electrical conditions that might be harmful to the rescuer.
