Adjustable CPR Device Telescopic Legs Patient Size Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional CPR devices are designed for average-sized adults and often fail to effectively accommodate patients of different sizes, leading to inefficiencies or harm during CPR.
Innovation Solution
An adjustable mechanical CPR device with telescopic support legs and a motorized chest compression mechanism that can be adjusted to fit various patient sizes by locking in different positions relative to the chest compression mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional CPR devices are designed for average-sized adults, then the device structure is simplified and manufacturing cost is reduced, but the device cannot effectively accommodate patients of different sizes
Solution Approach 1:
The support legs are designed as telescopic structures with adjustable lengths, allowing the device to dynamically adapt its configuration to match different patient sizes. The legs can be extended or retracted and locked at various positions, transforming a static device into one with dynamic adaptability.
Solution Approach 2:
The adjustable support legs enable a single CPR device to serve multiple patient size categories (pediatric, adult, and large adult), making the device universal. This eliminates the need for multiple specialized devices while maintaining effectiveness across different patient populations.
2Adaptability or versatility
If CPR devices are built specifically for smaller or larger patients, then the device can effectively accommodate that specific patient size, but multiple devices are required which increase storage space
Solution Approach 1:
The CPR device with adjustable support legs functions as a universal device that can be configured for pediatric, adult, and large adult patients. This single multi-functional device replaces the need to carry multiple size-specific devices, reducing the quantity of equipment required.
Solution Approach 2:
The telescopic support legs utilize a nested structure where inner leg portions are housed within outer leg portions. When not in use, the legs can be retracted into a compact configuration, reducing the storage space required compared to carrying multiple separate devices.
3Adaptability or versatility
If the chest compression mechanism is moved closer to the patient's chest for smaller patients, then the device can be used on smaller patients, but the device becomes off-balance and performs compressions less effectively
Solution Approach 1:
The support legs provide dynamic balance adjustment through their telescopic mechanism. As the compression mechanism position changes to accommodate different patient sizes, the legs can be extended or retracted to maintain the device's center of gravity and structural balance, ensuring reliable compression delivery.
Solution Approach 2:
The adjustable support legs act as counterbalancing elements. When the compression mechanism is repositioned for smaller patients, the legs can be adjusted to compensate for the shifted weight distribution, maintaining device balance and preventing the off-balance condition that would compromise compression effectiveness.

AI summary
An adjustable chest compression device that can adjust to accommodate a variety of patient sizes. The chest compression device can include adjustable support legs structured to support the chest compression mechanism at a distance from the base member and adjust to accommodate a patient size. Another adjustable chest compression device can include adjustable legs that can adjust to accommodate different patient sizes, as well as perform the chest compressions using the adjustable legs. An extension, such as a back plate and/or leg extension can be added to a chest compression device to make the chest compression device taller and/or wider to accommodate larger patients.
