CPR Support Pillow Geometry for Hands-Free Airway Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for maintaining proper head and neck positioning during cardiopulmonary resuscitation are unreliable and require manual effort, often failing to maintain the necessary alignment for effective airway management.
Innovation Solution
A medical support pillow with inclined surfaces for the neck and head, designed to position a patient's airway at specific angles, allowing for safe and accurate alignment, and constructed from durable, lightweight materials for easy transport and use by emergency responders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual head positioning techniques are used during CPR, then the responder can maintain proper head-tilt chin-lift position, but the responder's hands are occupied and cannot be used for effective CPR compression
Solution Approach 1:
The pillow is designed with pre-configured inclined surfaces that automatically position the victim's head and neck in the correct anatomical alignment when the victim is placed upon it. The geometry of the pillow (45-degree head support surface and 60-degree neck support surface) self-adjusts to achieve proper head-tilt chin-lift positioning without requiring manual intervention, thereby freeing the responder's hands for CPR compression while maintaining reliable head positioning
2Adaptability or versatility
If a device is designed to accommodate all patient sizes from small children to large adults, then the device becomes more complex and harder to manufacture
Solution Approach 1:
The pillow employs universally scalable geometric principles with inclined surfaces designed at specific angles (45 degrees for head, 60 degrees for neck) that provide proper anatomical alignment regardless of patient size. The pillow's overall dimensions can be scaled while maintaining the critical angular relationships, allowing a single design to serve infants, children, and adults without requiring multiple specialized devices or complex adjustable mechanisms

AI summary
A medical support pillow comprising of a pair of oppositely positioned sidewalls, a bottom portion having a bottom surface, and an upper portion. The support pillow includes a head support and neck support, which are dimensioned to automatically align the airways to facilitate CPR when head and neck are positioned thereupon. The upper portion has two opposing inclined surfaces. The first inclined surface for receiving and supporting the individual's neck, the second oppositely positioned inclined surface for supporting the individual's head. In a further embodiment, the medical support pillow has a circular indentation, which curves inwardly on the upper portion which hold and support and individual's neck to prevent substantial movement of the individual's head. In a further embodiment, the medical support pillow includes a hollowed out section on both right and left side of base creating handles making the medical support pillow easy to carry and transport.
