Adjustable Back Plate Segmentation for Mechanical CPR Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mechanical CPR devices are designed for a specific patient size range, excluding smaller or larger patients who may not fit within these specifications, leading to potential injury from improper compression depth and ad-hoc solutions that are not precise or safe.
Innovation Solution
Adjustable back plates or backboards that accommodate various patient sizes through telescoping, folding, or modular designs, allowing for customizable fit and secure attachment to mechanical compression devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If mechanical compression devices are designed for a specific patient size range, then device complexity is reduced and ease of manufacture is improved, but adaptability to different patient sizes deteriorates
Solution Approach 1:
The back plate is divided into multiple segments or sections that can be adjusted relative to each other. This segmentation allows the back plate to be configured in different lengths and shapes to accommodate various patient sizes while maintaining a standardized base design for manufacturing efficiency.
Solution Approach 2:
The back plate incorporates adjustable or movable components that allow it to be reconfigured for different patient sizes. This dynamic adaptability enables a single device design to serve multiple patient populations without requiring completely different devices for each size category.
2Adaptability or versatility
If ad-hoc solutions like towels are used to accommodate smaller patients, then adaptability is improved, but measurement precision and reliability deteriorate
Solution Approach 1:
The back plate features adjustable components that allow precise positioning and configuration tailored to each patient's size. This controlled adjustability provides both adaptability to different patients and measurement precision through defined adjustment increments and positioning mechanisms.
Solution Approach 2:
The back plate allows for controlled changes in geometric parameters such as length, width, and curvature through standardized adjustment mechanisms. This ensures that adaptations to different patient sizes are made with precision rather than through imprecise ad-hoc modifications.
3Adaptability or versatility
If compression depth is not controlled correctly in ad-hoc approaches, then adaptability to different patient sizes is improved, but harmful factors increase
Solution Approach 1:
The adjustable back plate enables proper positioning of the compression device relative to the patient's anatomy for different body sizes. This dynamic adjustment ensures that compression depth is controlled and appropriate for each patient, preventing both insufficient and excessive compression that could cause harm.
Solution Approach 2:
The back plate is configured in advance to provide proper anatomical positioning and support before compression begins. This pre-positioning ensures that the compression force is applied at the correct depth and location, preventing harmful effects from improper compression depth while maintaining adaptability to different patient sizes.
