Segmented CPR Protection Device for Defibrillation Shock Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing CPR practices face challenges in preventing electrical shock to rescuers during defibrillation while maintaining access to essential patient contact points for advanced cardiac life support tasks, as conventional barriers like gloves and polyethylene sheets fail to meet safety standards and obstruct access to vital areas.
Innovation Solution
A CPR protection device with a chest portion and wing portions, constructed of materials with high electrical resistance, provides a patient-based electrical barrier that allows defibrillation while ensuring access to the neck, arms, and abdomen, reducing the risk of electrical leakage to rescuers and facilitating seamless rescuer transitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional barriers like gloves or polyethylene sheets are used to protect rescuers during defibrillation, then electrical shock protection is provided, but access to essential patient contact points (neck, arms, abdomen) is obstructed
Solution Approach 1:
The barrier is divided into distinct functional zones: a chest portion for electrical protection during defibrillation and separate wing portions that extend to cover the neck, arms, and abdomen. This segmentation allows each zone to serve its specific purpose - the chest portion provides electrical isolation while the wing portions maintain access to vital areas for ACLS procedures
Solution Approach 2:
Different portions of the barrier have different functional properties. The chest portion is designed primarily for electrical protection during defibrillation, while the wing portions are designed to provide both protection and access to specific body regions. This local differentiation of function resolves the contradiction by allowing the barrier to protect where needed while maintaining access where required
2Productivity
If rescuers perform chest compressions continuously without pauses, then CPR effectiveness is improved, but electrical shock safety during defibrillation cannot be maintained
Solution Approach 1:
The barrier is applied to the patient before defibrillation occurs, establishing electrical protection in advance. This preliminary action ensures that when defibrillation is needed, the rescuer is already protected, allowing continuous CPR without interruption while maintaining safety during the shock delivery
3Object-affected harmful factors
If a full-body barrier is used to ensure electrical protection, then rescuer safety is improved, but access to critical areas for ACLS tasks is blocked
Solution Approach 1:
The barrier is segmented into a chest portion and wing portions that can be independently positioned. The wing portions extend laterally to cover the neck, arms, and abdomen, providing electrical protection in those areas while leaving the chest accessible for defibrillation and CPR. This segmentation enables the barrier to adapt to different operational requirements

Function Achieved in This Case
The device effectively limits electrical leakage to rescuers, maintains access to critical patient areas for ACLS tasks, and enables efficient chest compressions without pauses, thereby improving patient survival rates by minimizing peri-shock pauses.

AI summary
Cardiopulmonary Protection Devices may be provided by a device comprising: a chest portion having at least a first electrical resistance; a first and second wing portion, each having at least a second electrical resistance, wherein the chest portion is joined to the first wing portion and second wing portion via a first joinery section and a second joinery section, respectively; wherein the chest portion, when deployed, covers a chest area of a patient sufficient to simultaneously accommodate a rescuers hands and defibrillator pads, while at least a windpipe and neck area, a forearm area, and a subxiphoid area of the patient are unobscured by the CPR protection device; wherein the first electrical resistance is sufficient to limit a leakage current resulting from a defibrillation shock though the chest portion to a predetermined amperage.
