A-CPR Backboard Structure for Stable Patient Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automated cardio pulmonary resuscitation (A-CPR) systems cause patient movement and injuries due to insufficient fixation and forceful mechanical stimulation, leading to long setup times and potential fractures, punctured organs, and other trauma-related injuries.
Innovation Solution
A backboard with adjustable shoulder stops and extendable connectors to stabilize patients, featuring a neck rest and head support for improved positioning and fixation, allowing for quick and precise attachment of the A-CPR unit, even with large or obese patients, while preventing movement and facilitating easy cleaning and scanning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If forceful mechanical stimulation is applied to the patient's sternum during automated CPR, then effective resuscitation is achieved, but patient movement relative to the backboard occurs causing injuries
Solution Approach 1:
The backboard incorporates shoulder stops and side stops that preemptively counteract the forward movement of the patient's upper body during chest compressions. These stops create preliminary opposing forces that prevent the patient from moving relative to the backboard, thereby eliminating the harmful effect of movement-induced injuries while allowing full-force mechanical stimulation to proceed
2Loss of time
If the backboard design is simplified for quick setup, then setup time is reduced, but patient positioning accuracy and stabilization are compromised
Solution Approach 1:
The backboard features pre-configured shoulder stops and side stops that are automatically positioned when the backboard is placed under the patient. This preliminary arrangement of stabilization elements eliminates the need for manual adjustment during setup, achieving both quick setup and accurate patient positioning simultaneously
Solution Approach 2:
The stop mechanisms are designed to self-adjust to the patient's body contours upon placement, automatically achieving proper positioning without requiring external intervention or complex adjustment procedures by rescue personnel
3Reliability
If the backboard provides extensive stabilization features for all patient sizes, then patient fixation is improved, but device complexity increases
Solution Approach 1:
The shoulder stops and side stops are designed with adjustable positioning capabilities that allow a single backboard structure to effectively stabilize patients of various sizes. The stops can be positioned at multiple locations along the backboard edges, providing universal applicability across different patient anatomies without requiring multiple specialized backboard designs
Solution Approach 2:
The stop mechanisms incorporate movable or adjustable components that can be repositioned along the backboard edges to accommodate different patient sizes and body types. This dynamic adjustability allows the same structural elements to serve multiple stabilization functions rather than requiring fixed, size-specific designs
