CPR Stabilizing Member Prevents Tilting During Chest Compressions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual cardiopulmonary resuscitation (CPR) can be ineffective due to human error and fatigue, leading to suboptimal chest compressions that may not maintain necessary blood circulation to prevent organ damage and death, especially in emergency situations where trained rescuers may not perform compressions frequently or deeply enough.
Innovation Solution
A CPR system comprising a retention structure, compression mechanism, backboard, and stabilizing member that forms a closed loop around the patient's torso, with a modular stretcher design allowing for assembly and disassembly for easy storage and transportation, and a coupler to secure the stabilizing member to the backboard, preventing tilting and ensuring consistent compression delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual CPR is performed by trained rescuers, then the patient receives chest compressions, but the compressions may be ineffective due to human error and fatigue
Solution Approach 1:
The CPR system performs chest compressions automatically without requiring continuous human intervention. The mechanical compression device self-regulates the compression rhythm and depth, eliminating human error and fatigue while maintaining consistent compression delivery throughout the resuscitation process
Solution Approach 2:
The patent replaces the manual mechanical system of human rescuers with an automated mechanical compression device. This substitution ensures reliable, consistent chest compressions by using mechanical precision rather than human physical capability, directly addressing the unreliability of manual CPR
2Manufacturing precision
If the retention structure is held stable during CPR, then consistent compression delivery is achieved, but the structure may tilt without proper stabilization
Solution Approach 1:
The stabilizing member acts as an intermediary element between the retention structure and the external environment. It provides the necessary stabilization and support to prevent tilting of the retention structure, thereby enabling precise and consistent compression delivery without compromising structural stability
3Adaptability or versatility
If the CPR system is designed as a complete assembly, then it provides full functionality, but it is difficult to store and transport
Solution Approach 1:
The CPR system is divided into separable components including the retention structure, compression mechanism, stabilizing member, and modular stretcher. This segmentation allows the system to be disassembled for compact storage and easy transportation, while maintaining full functionality when assembled and deployed

AI summary
In embodiments, a Cardio-Pulmonary Resuscitation (CPR) system includes a retention structure, a compression mechanism coupled to the retention structure and a backboard. The retention structure and the backboard can be assembled together so as to form a closed loop that surrounds the patient's torso, and a piston of the compression mechanism is movable towards and away from a chest of a patient. In addition, the CPR system has a stabilizing member, and a coupler configured to couple the stabilizing member to the backboard. The stabilizing member can prevent the retention structure from tilting while the CPR system delivers chest compressions to the patient.
