Adjustable CPR Backboard for Variable Patient Size Support
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 the inability to perform effective mechanical CPR.
Innovation Solution
The development of adjustable back plates or backboards that accommodate various patient sizes through telescoping, folding, or modular designs, allowing for precise and consistent mechanical compressions by varying the distance between connectors and using different patient-specific configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mechanical CPR devices are designed for a specific patient size range, then the device can provide consistent compression for patients within the acceptable range, but patients outside this range (smaller or larger) cannot receive effective mechanical CPR
Solution Approach 1:
The backboard incorporates an adjustable elongated portion that can be configured in multiple lengths to accommodate different patient sizes. The telescoping mechanism allows the backboard to dynamically adapt its dimensions while maintaining structural stability during compression, ensuring reliable CPR delivery across various patient populations.
Solution Approach 2:
The backboard is divided into multiple segments including a first portion, second portion, and third portion that can be independently adjusted. This segmentation allows each section to be optimized for different patient body types and sizes, maintaining compression effectiveness while improving overall adaptability.
2Adaptability or versatility
If ad-hoc solutions such as placing towels or adjusting piston position are used for pediatric patients, then smaller patients can be accommodated, but significant injury to the patient may occur if not performed correctly
Solution Approach 1:
The mechanical CPR device incorporates sensors that detect the patient's size and provide feedback to the control system. This feedback mechanism automatically adjusts compression parameters such as depth and speed to match the patient's specific requirements, eliminating the need for manual ad-hoc adjustments and reducing the risk of injury.
Solution Approach 2:
The device performs self-adjustment based on detected patient characteristics. The control system automatically modifies compression settings without requiring manual intervention, ensuring that the correct compression parameters are applied to minimize injury risk while maintaining effectiveness.
3Adaptability or versatility
If the backboard uses a fixed rigid structure, then manufacturing is simple and cost-effective, but it cannot accommodate patients of various sizes
Solution Approach 1:
The backboard employs a telescoping design where the second portion nests within the first portion, and the third portion nests within the second portion. This nested structure allows the backboard to compact when not in use and expand to various lengths during operation, achieving adaptability without excessive structural complexity.

AI summary
An adjustable-size backboard for a chest compressions device having a first connector, a second connector, and an adjustable elongated portion extending between the first connector and the second connector. The first connector is structured to attach to a first leg of a chest compression device. The second connector is structured to attach to a second leg of the chest compression device. The adjustable elongated portion includes a first portion that extends from the first connector and a second portion. The second portion is between the first connector and the second connector and is structured to slide relative to the first portion.
