Wearable CPR Support Device for Rescuer Fatigue Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current CPR devices do not provide adequate support or relief from anatomical strain and fatigue during chest compressions, particularly for individuals with smaller stature or those suffering from hand and wrist disorders, leading to reduced effectiveness and increased risk of injury.
Innovation Solution
A wearable support device that provides compressive support to the wrist, hand, forearm, and arm, incorporating sensors and feedback components to enhance CPR performance by maintaining proper angle and reducing fatigue, while alleviating symptoms of wrist and hand ailments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If CPR is performed without interruption over a three minute period, then continuous chest compressions are maintained, but rescuer fatigue adversely affects the quality of chest compressions
Solution Approach 1:
The device segments the support function by providing a wrist-specific support mechanism that can be independently adjusted. The wrist support is a separate component that can be worn independently or with other CPR equipment, allowing targeted support to the wrist joint without requiring full-body support equipment.
Solution Approach 2:
The wrist support device acts as an intermediary between the rescuer's wrist and the CPR compression force. It provides a mechanical interface that distributes and supports the load on the wrist joint, reducing the direct stress on wrist structures during prolonged compression sequences.
2Ease of operation
If wrist or hand support is provided during CPR, then anatomical strain and fatigue are reduced, but device complexity increases
Solution Approach 1:
The invention extracts the wrist support function from complex full-body support systems or advanced exoskeletons. By focusing solely on wrist support with a simple wearable device, it provides targeted assistance without the complexity of comprehensive mechanical support systems.
Solution Approach 2:
The wrist support device is designed to be self-adjusting and passive, requiring no active control systems, power sources, or complex adjustments by the user. The support structure automatically adapts to wrist movements and provides consistent support through its mechanical design alone.
3Measurement precision
If compression depth and rate are monitored, then feedback on CPR quality is provided, but device complexity increases
Solution Approach 1:
The wrist support device serves multiple functions simultaneously: it provides mechanical wrist support to reduce fatigue while also incorporating sensors for monitoring compression depth and rate. This multi-functionality is achieved in a single integrated device rather than requiring separate support and monitoring equipment.
Solution Approach 2:
The device incorporates feedback mechanisms through sensors that measure compression parameters and provide information about CPR quality. This feedback loop allows real-time monitoring without requiring complex analysis systems, as the sensors directly measure physical parameters of interest.
4Strength
If wrist support is provided through compression, then structural support and fatigue reduction are achieved, but comfort may be compromised
Solution Approach 1:
The wrist support device applies compression and support locally to specific areas of the wrist that require stabilization during CPR. Rather than uniformly compressing the entire wrist, the device targets key structural points to provide support while minimizing discomfort in other areas.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device enhances the ability to perform CPR with reduced fatigue and discomfort, allowing for longer durations and improved technique, particularly benefiting individuals with smaller stature or wrist-related issues, by providing structural support and monitoring feedback.
Implementation Method 1
