Active CPR Backboard for Rapid Chest Compression Alignment

Solution Overview

Problem

The correct positioning of mechanical CPR devices on a patient's chest is challenging during emergencies, leading to ineffective chest compressions and increased time without proper treatment, which can cause irreversible organ damage.

Innovation Solution

The development of an active backboard that can adjust its position relative to the patient or the patient relative to the backboard, using mechanisms such as sliding layers, roller bars, wheels, projections, and adjustable connectors, to ensure precise alignment with the CPR device without the need for manual repositioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual positioning of mechanical CPR device backboard is used, then device structure is simple, but alignment time increases and positioning accuracy deteriorates

Engineering Contradiction:

Improvealignment accuracyVSAvoidalignment time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The backboard incorporates movable components including a sliding mechanism that allows the backboard to move along the longitudinal axis, and adjustable support legs with telescopic structures. These dynamic elements enable rapid adjustment of backboard position and angle to achieve precise alignment with the patient's chest without manual repositioning, directly resolving the contradiction between alignment accuracy and alignment time.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The backboard includes self-adjusting features such as automatic leveling mechanisms and self-aligning connectors that automatically position the backboard correctly when placed on the patient. The support legs automatically adjust their length and angle to achieve proper alignment, eliminating the need for manual intervention and reducing alignment time while maintaining high positioning accuracy.

Inventive Principle:

Principle #25Self-service

2Reliability

If manual repositioning of backboard is required, then device complexity is low, but CPR effectiveness deteriorates due to delays

Engineering Contradiction:

ImproveCPR effectivenessVSAvoidbackboard structure

Core Design Contradiction:

3Adaptability or versatility

If fixed backboard position is used, then device structure is simple, but adaptability to different patients deteriorates

Engineering Contradiction:

Improvepatient size accommodationVSAvoidadjustment mechanism

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The backboard incorporates movable components including a sliding mechanism that allows the backboard to move along the longitudinal axis, and adjustable support legs with telescopic structures. These dynamic elements enable rapid adjustment of backboard position and angle to achieve precise alignment with the patient's chest without manual repositioning, directly resolving the contradiction between alignment accuracy and alignment time.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The backboard is divided into multiple independent adjustment components: the main backboard platform, adjustable support legs, and positioning mechanisms. Each component can be independently adjusted to accommodate different patient sizes and anatomical variations. The support legs can be adjusted in length and angle, while the backboard itself can slide to fine-tune the position, providing versatile adaptability without requiring a completely different device for each patient type.

AI summary

A backboard for a mechanical cardiopulmonary resuscitation (CPR) device having a first connector, a second connector, an elongated portion, and a position adjustment mechanism. The first connector is structured to couple to a first leg of the mechanical CPR device. The second connector structured to couple to a second leg of the mechanical CPR device. The elongated portion extends along an axis between the first connector and the second connector. The position adjustment mechanism is structured to adjust a patient position on the elongated portion in an adjustment direction that is perpendicular to the axis between the first connector and the second connector.
