Peripheral Display CPR Patch for Unobstructed Visual Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing CPR assistance devices face challenges in providing unobstructed visual feedback during chest compressions, as the display is often obscured by the rescuer's hands and can be difficult to read from an awkward angle, leading to potential distractions and technique deviations.
Innovation Solution
A CPR assistance device with a self-adhesive, flexible patch featuring a visual display arrayed around the periphery, incorporating LEDs and a dual-use release liner that acts as a ventilation barrier, providing tactile feedback and automatic activation, ensuring feedback is always visible and accessible.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the display is positioned on the face of the CPR assistance device, then the feedback information is provided to the user, but the display is obscured by the rescuer's hands and difficult to read from awkward angles
Solution Approach 1:
The display is repositioned from the face of the device to the periphery edge, utilizing a different spatial dimension. This peripheral positioning allows the display to remain visible while the rescuer's hands are on the device face, eliminating the obscuration problem while maintaining feedback visibility.
Solution Approach 2:
The device is divided into distinct functional zones: the face area for hand placement and compression, and the peripheral edge area for display output. This segmentation separates the interaction surface from the information display surface, allowing both functions to operate simultaneously without interference.
2Ease of manufacture
If the CPR assistance device is made disposable and flexible, then the device is easier to deploy and cost-effective, but the structural complexity increases
Solution Approach 1:
The CPR assistance device utilizes a flexible patch structure with multiple thin layers including adhesive layer, barrier layer, and display layer. This flexible multi-layer construction enables easy deployment and disposal while maintaining the necessary functional complexity through layered integration rather than rigid complex mechanisms.
Solution Approach 2:
The release liner serves multiple functions: it protects the adhesive layer during storage and transport, acts as a barrier layer during CPR, and provides structural support. This multi-functionality reduces the need for separate components, simplifying the overall device structure despite the flexible disposable nature.
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 ensures continuous, unobstructed visual feedback and improved usability by positioning the display peripherally, allowing rescuers to maintain proper technique without distraction, even during handovers and varying positions, while being cost-effective and disposable for easy deployment.
Implementation Method 1
The CPR assistance device may be attached to the patient by an adhesive layer present on a lower portion of the housing
Implementation Method 2
featuring a visual display arrayed around the periphery, incorporating LEDs

AI summary
A cardiopulmonary resuscitation (CPR) assistance device (400) is described for use by a rescuer providing manual CPR. The device has a visual indicator (430, 418, 420, 422) arranged about its periphery, such that visual assistance to the rescuer can be provided regardless of the rescuer' s hand position. The CPR assistance device also includes a staged method of providing visual assistance, such that increasingly urgent information is provided if the sensed CPR accuracy fails to improve.
