Active Backboard Alignment for Mechanical CPR Compression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual CPR can be ineffective, and mechanical CPR devices require precise alignment on the patient's chest, which is challenging during emergencies, leading to wasted time and potential organ damage due to incorrect positioning.
Innovation Solution
The development of a backboard that can adjust itself or the patient relative to the mechanical CPR device, using mechanisms like sliding layers, roller bars, wheels, projections, and adjustable connectors to ensure proper alignment without repositioning the backboard.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the backboard is positioned first before attaching the upper portion, then the device can be assembled systematically, but it wastes valuable time having to readjust the backboard with respect to the patient if incorrectly positioned
Solution Approach 1:
The backboard incorporates alignment features such as alignment pins, alignment grooves, or alignment markers that are pre-configured to guide the upper portion into correct alignment with the patient's chest. This preliminary alignment configuration eliminates the need for time-consuming readjustment after initial placement, as the alignment features automatically ensure proper positioning when the upper portion is attached.
Solution Approach 2:
Alignment features act as intermediary elements between the backboard and the upper portion, facilitating automatic alignment during assembly. These intermediary alignment mechanisms (such as alignment pins fitting into alignment grooves or alignment markers providing visual guidance) serve as mediators that ensure correct positioning without requiring manual measurement or adjustment, thus resolving the contradiction between systematic assembly and time efficiency.
2Ease of operation
If the upper portion is not aligned correctly with the patient, then the backboard can be repositioned, but this results in additional time that CPR compressions are not performed
Solution Approach 1:
The backboard includes pre-configured alignment features such as alignment pins, alignment grooves, or alignment markers that automatically guide the upper portion into correct alignment with the patient's chest during initial placement. This preliminary alignment configuration prevents misalignment issues before they occur, eliminating the need for repositioning and ensuring that CPR compressions can begin immediately without time loss.
Solution Approach 2:
Alignment features serve as intermediary elements that mediate between the backboard placement and upper portion attachment, ensuring automatic correct alignment. These intermediary mechanisms (alignment pins, grooves, or markers) prevent misalignment by providing physical or visual guidance during assembly, thus preventing the need to stop CPR for repositioning and maintaining continuous compression performance.
3Device complexity
If manual CPR is performed, then no special equipment is needed, but it may be ineffective and lead to irreversible damage to the patient's vital organs
Solution Approach 1:
The mechanical CPR device is divided into two main segments: the backboard that can be positioned on the patient's chest, and the upper portion containing the compression mechanism. This segmentation allows the device to remain simple and easy to deploy (like manual CPR) while incorporating mechanical automation in the upper portion to ensure effective, consistent compressions that prevent organ damage, thus resolving the contradiction between simplicity and reliability.
Solution Approach 2:
The mechanical CPR device performs the compression function automatically once positioned, eliminating the need for continuous manual intervention. The device self-regulates the compression rhythm, depth, and rate, ensuring consistent effective compressions without requiring the rescuer to maintain manual effort, thus improving reliability while keeping the overall system relatively simple to deploy.

AI summary
An active backboard that can assist with adjusting a patient on the backboard to ensure that the backboard is correctly aligned for a compression mechanism of an upper portion of a mechanical cardiopulmonary resuscitation (CPR) device to perform compressions. The active backboard can also include multiple layers that can slide or move relative to each other to move the patient relative to the backboard. The active backboard can include roller bars, a wheel, and/or projections to assist with moving a patient relative to the backboard.
