Solution Overview

Problem

Single rescuers experience muscle fatigue and performance degradation during prolonged chest compressions due to their inherently mechanically disadvantaged position, necessitating multiple rescuers for sustained CPR, which is inefficient and fatiguing.

Innovation Solution

A chest compression assist glove with a hemispheric projection (power ball) and a stiff palm plate that translates and consolidates force from the rescuer's hand to the victim's chest, providing mechanical advantage through synchronized wrist and elbow movements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of stationary object

If multiple rescuers are used for sustained CPR, then chest compression quality is maintained, but rescuer fatigue is reduced and operational sustainability is improved

Engineering Contradiction:

Improveduration of effective chest compressionsVSAvoidrescuer efficiency

Core Design Contradiction:

Duration of action of stationary objectVSProductivity

Solution Approach 1:

The assist glove acts as an intermediary device between the rescuer's hand and the victim's chest. The rigid palm plate and hemispheric projection transmit and amplify the rescuer's mechanical force more effectively, allowing one rescuer to maintain compression quality equivalent to or better than multiple rescuers would achieve manually.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The glove changes the mechanical parameters of force transmission by introducing a rigid palm plate and hemispheric projection. These structural elements modify the force vector and distribution, increasing the effectiveness of each compression while reducing the metabolic cost to the rescuer, thereby extending sustainable operation time.

Principle #35Parameter changes

2Reliability

If proper chest compression technique is used, then blood flow and perfusion to brain and heart are preserved, but rescuer muscle fatigue increases due to mechanically disadvantaged position

Engineering Contradiction:

Improvequality of chest compressionsVSAvoidduration of rescuer performance

Core Design Contradiction:

ReliabilityVSDuration of action of moving object

Solution Approach 1:

The rigid palm plate serves as a mechanical intermediary that bridges the rescuer's hand and the chest. It maintains proper compression technique and force direction while reducing the mechanical disadvantage of the rescuer's wrist and elbow position, allowing sustained performance.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The glove combines flexible glove material with rigid structural elements (palm plate and hemispheric projection). This composite construction provides the necessary mechanical advantage and force transmission while maintaining comfort and fit, enabling prolonged use without rescuer fatigue.

AI summary

A chest compression assist glove is disclosed herein. The chest compression assist glove solves numerous problems in the performance of CPR by a human and is intended to provide mechanical advantage for a single rescuer performing chest compressions. The chest compression assist glove disclosed herein mitigates the fatigue and degradation of performance experienced by the rescuer due to the high energy demands of performing an intrinsically mechanically disadvantaged action over a sustained period.
