CPR Back Plate Tower Attachment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual cardiopulmonary resuscitation (CPR) is labor-intensive and inefficient, leading to fatigue and reduced effectiveness over time, as well as diverting medical personnel's attention from other critical tasks, while traditional mechanical CPR devices can be cumbersome and prone to displacement when patients are moved.
Innovation Solution
A mechanical CPR device with a back plate and two towers that securely attach to each other and a beam, allowing for adjustable and stable chest compression, featuring a motorized system with control units for precise compression control and wireless connectivity to facilitate efficient and consistent CPR performance across various patient positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual CPR is performed, then circulatory and respiratory functions can be maintained, but considerable physical effort is required leading to fatigue and reduced effectiveness over time
Solution Approach 1:
The patent replaces the manual mechanical compression system with an automated mechanical compression device. The device uses a motorized mechanism to perform chest compressions, eliminating the need for continuous manual physical effort while maintaining consistent compression depth and rate. This substitution resolves the contradiction by providing reliable CPR effectiveness without the deteriorating physical effort requirement.
Solution Approach 2:
The mechanical compression device operates autonomously to perform CPR compressions without requiring continuous human intervention. Once positioned, the device self-regulates the compression cycle, maintaining proper timing and depth without operator fatigue. This self-service capability ensures sustained CPR effectiveness independent of operator physical condition.
2Productivity
If manual CPR is performed, then chest compressions can be delivered, but mental attention must be diverted from other critical tasks
Solution Approach 1:
By replacing manual compression delivery with an automated mechanical system, the patent frees the operator's mental attention. The device independently manages the compression function, allowing medical personnel to focus on other critical tasks such as monitoring patient vitals, preparing defibrillators, or communicating with the care team, thereby eliminating the attention diversion problem.
3Extent of automation
If traditional mechanical CPR devices are used, then compressions can be automated, but the devices are cumbersome and prone to displacement when patients are moved
Solution Approach 1:
The patent divides the mechanical compression device into separate modular components: a compression mechanism that can be positioned over the sternum and a back plate that attaches to the patient's back. This segmentation allows independent optimization of each component's stability and positioning, reducing the cumulative complexity and displacement risk associated with traditional integrated designs.
Solution Approach 2:
The patent introduces a vertical dimension to device stability by using a back plate anchored to the patient's back as a foundation. This creates a stable base that prevents horizontal displacement, while the compression mechanism operates vertically above the sternum. This dimensional separation of stabilization and compression functions resolves the contradiction between automation and stability.

AI summary
A mechanical CPR device can include a back plate, a first tower, and a second tower. The back plate can have a first side and a second side. The first tower can include a first foot and the second tower can include a second foot. The first and second towers can be configured to securely hold a beam above the back plate. The first side of the back plate can be configured to be held to the first foot of the first tower and the second side of the back plate can be configured to be held to the second foot of the second tower when a distributed weight is placed on the back plate.
