Pivoting CPR Support Arm for Consistent Chest Compressions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mechanical CPR devices are limited by their sensitivity to patient size and require significant physical effort, leading to inconsistent compressions and reduced effectiveness over time, while also diverting medical personnel's attention from other critical tasks.
Innovation Solution
A CPR device with a pivoting support arm that delivers compressions by pivoting over the patient's head and shoulders, allowing for use on a wider range of patient sizes and reducing the need for manual effort, featuring a pivot actuator and controller for consistent compression delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual CPR is performed by medical personnel, then compressions can be delivered to the patient, but the personnel must exert considerable physical effort leading to fatigue and inconsistent compressions
Solution Approach 1:
The patent replaces the manual mechanical system with an automated mechanical CPR device that uses a motor-driven compression mechanism. The device incorporates a compression member actuated by a motor through a transmission mechanism, eliminating the need for manual physical effort while maintaining consistent compression force and depth throughout the procedure.
Solution Approach 2:
The CPR device is designed to perform compressions autonomously without requiring continuous human intervention. The motorized system self-regulates compression timing, depth, and rate according to programmed parameters, allowing the device to service itself and maintain reliable performance without operator fatigue.
2Productivity
If medical personnel perform manual CPR, then compressions are delivered, but attention is diverted from other critical tasks
Solution Approach 1:
By replacing manual CPR with an automated mechanical device, medical personnel are freed from the continuous physical task of compression delivery. The device operates autonomously according to programmed protocols, allowing personnel to allocate their attention and time to other critical patient care tasks such as airway management, monitoring, and preparing for defibrillation.
3Adaptability or versatility
If existing mechanical CPR devices pass over the patient's torso and arms, then compressions can be delivered, but the device is sensitive to patient size and cannot accommodate all patients
Solution Approach 1:
The patent changes the spatial arrangement by positioning the compression member to approach the patient's chest from above rather than from the side. This vertical approach allows the compression member to pivot down onto the sternum, accommodating patients of various sizes including those with larger torso or arm dimensions that would interfere with side-approach devices.
Solution Approach 2:
The device incorporates a pivotable support arm that can dynamically adjust its position and angle. This dynamic configuration allows the compression member to be positioned optimally for different patient anatomies, improving adaptability across various patient sizes and body types without requiring multiple fixed-configuration devices.
