A-CPR Backboard with Adjustable Stops for Patient Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automated cardio pulmonary resuscitation (A-CPR) systems face challenges in stabilizing patients due to force-induced movement caused by mechanical stimulation, leading to potential injuries and prolonged setup times due to insufficient fixation and positioning issues.
Innovation Solution
A backboard with adjustable shoulder stops and extendable connectors, along with a neck rest and head rest, provides enhanced stabilization and fixation, allowing for precise and gentle positioning of the A-CPR unit, reducing the risk of injury and facilitating quick setup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If mechanical heart-stimulator provides forceful mechanical stimulation, then resuscitation effectiveness is improved, but patient stability deteriorates due to force-induced movement
Solution Approach 1:
The backboard provides preliminary stabilization of the patient before mechanical heart-stimulation begins. The shoulder stops and head rest are positioned in advance to prevent force-induced movement during the high-power mechanical stimulation phase.
2Stability of the object's composition
If patient positioning is adjusted to prevent movement, then patient stability is improved, but setup time increases
Solution Approach 1:
The backboard is pre-configured with shoulder stops and head rest in fixed positions that automatically stabilize the patient once they are placed on the board, eliminating the need for time-consuming adjustments during the resuscitation process.
3Stability of the object's composition
If backboard provides rigid fixation, then patient stability is improved, but adaptability to different patient sizes deteriorates
Solution Approach 1:
The shoulder stops are designed to be adjustable in position along the backboard, allowing rescue personnel to adapt the fixation points to different patient sizes and anatomical variations while maintaining stable patient positioning during mechanical heart-stimulation.
