Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual CPR can be ineffective due to rescuer fatigue and inability to maintain proper compression frequency and depth, leading to inadequate blood circulation and potential organ damage.
Innovation Solution
A CPR chest compression system with a retention structure and motorized compressor powered by a battery that can be easily replaced, allowing for continuous operation and smart battery management to optimize power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual CPR is performed by rescuers, then human judgment and flexibility can be applied, but rescuer fatigue and inability to maintain proper compression frequency and depth occur
Solution Approach 1:
The patent replaces the manual mechanical system of human rescuers with an automated mechanical CPR device that uses a motor-driven piston to deliver chest compressions. This substitution eliminates rescuer fatigue while maintaining consistent compression quality and frequency throughout the rescue operation.
Solution Approach 2:
The CPR device is designed to operate autonomously once activated, automatically performing compressions and releases at programmed intervals without requiring continuous human intervention. The device monitors and maintains its own operation, only requiring battery replacement when power is depleted.
2Ease of operation
If a battery is integrated close to the motor for compact design, then device structure is simplified, but battery replacement becomes difficult and interrupts treatment
Solution Approach 1:
The patent divides the battery from the motor assembly, creating separate modular components. The battery is housed in a removable battery compartment that can be independently accessed and replaced without disassembling the motor or interrupting the CPR treatment, allowing quick battery swaps while maintaining continuous operation.
Solution Approach 2:
The device includes a battery low-power mode that automatically activates when the battery is depleted, allowing the rescuer to replace the battery without interrupting the CPR treatment. The compressor continues operating in low-power mode during the brief battery replacement process.
3Reliability
If active decompression lifting is applied to assist chest decompression, then air circulation in the patient is improved, but device complexity increases
Solution Approach 1:
The patent combines the active decompression lifting function with the existing piston and suction cup components already used for compression. The same piston that delivers compressions also provides the lifting force for active decompression, eliminating the need for separate mechanical components and reducing overall device complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system ensures consistent and effective chest compressions, reducing the risk of rescuer fatigue and maintaining blood circulation, even during prolonged medical emergencies, while allowing for quick battery replacement without interrupting treatment.
Implementation Method 1
The CPR chest compression system is powered by a battery that can be replaced by the rescuer
Implementation Method 2
a motor and a compressor that can perform CPR compressions to the chest of the patient

AI summary
A CPR chest compression system includes a retention structure that retains the body of a patient, and a motor and a compressor that can perform CPR compressions to the chest of the patient. The motor is powered by a battery that is located on the retention structure but away from the motor, and is electrically connected to the motor via one or more wires. Accordingly the weight and volume of the battery can be located away from a top portion of the retention structure. This renders the CPR system is less heavy at the top, and therefore less likely to tilt and start compressing the chest at a different point. Moreover, this permits X-Rays of a larger footprint to go through the CPR system and reach the patient, in example configurations where the components are transparent to X-Rays.
