Disposable EEG Cap with Pre-Gelled Electrodes for Rapid Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electroencephalography (EEG) is underutilized due to the need for specially trained technicians to apply electrodes, high costs of existing devices, and time-consuming cleaning processes, making it difficult to perform in emergency situations and other settings where immediate diagnosis of conditions like non-convulsive status epilepticus, seizures, and strokes is critical.
Innovation Solution
A disposable EEG device with a self-adhesive backing and integrated, pre-gelled electrodes following a modified 10-20 electrode positioning system, designed for easy application by minimally trained personnel, featuring a sagittal and coronal portion with embedded electrodes and electrical connectors for connecting to an electroencephalograph.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditionally trained technicians apply electrodes using conductive gel, then measurement precision is improved, but device complexity and ease of operation deteriorate due to requiring specialized training and multiple components
Solution Approach 1:
The patent combines multiple electrode components into a single integrated cap structure with pre-positioned electrodes that follow the 10-20 system. The cap integrates electrode holders, conductive elements, and positioning features into one unit, eliminating the need for technicians to manually place multiple separate electrodes and reducing application complexity while maintaining measurement precision.
Solution Approach 2:
The electrodes are pre-positioned and pre-configured in the cap according to the 10-20 system before use. This preliminary arrangement of electrodes in their final positions eliminates the need for complex manual placement during application, allowing even minimally trained personnel to achieve accurate electrode positioning.
2Measurement precision
If expensive reusable EEG devices are used, then measurement precision is improved, but productivity deteriorates due to time-consuming cleaning and disinfecting processes
Solution Approach 1:
The patent employs disposable EEG caps that are discarded after a single use, eliminating the need for cleaning and disinfecting reusable devices. Each cap is designed to be used once and then discarded, which removes the time-consuming sterilization process entirely while maintaining signal quality through proper electrode design and materials.
3Measurement precision
If multiple separate electrodes are used following the 10-20 system, then measurement precision is improved, but device complexity deteriorates due to numerous components and wires
Solution Approach 1:
The patent merges multiple individual electrode components into a single integrated cap structure. The cap contains multiple electrode holders and conductive elements pre-arranged according to the 10-20 system, reducing the number of separate components and wires that must be handled while maintaining accurate electrode positioning across the scalp.
