Solution Overview
Problem
Current healthcare lacks sophisticated tools to objectively assess brain function, particularly in emergency situations like acute brain injury or stroke, with existing imaging modalities being costly, not universally available, and providing limited immediate information for timely intervention.
Innovation Solution
A portable apparatus using a reduced electrode set and advanced signal processing algorithms to assess brain activity, including spontaneous and evoked responses, for immediate functional brain state assessment, capable of distinguishing between normal and abnormal brain function, and identifying specific conditions such as seizures or organic abnormalities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If CT or MRI imaging studies are used to assess brain function, then structural/anatomical information is obtained, but functional information is not available and the tests are costly and not universally available
Solution Approach 1:
The patent replaces complex mechanical imaging systems (CT, MRI) with a simplified electrical measurement system that uses EEG electrodes to detect brain electrical activity. This substitution provides functional brain assessment capability without requiring expensive, complex imaging equipment, directly resolving the contradiction between measurement precision and device complexity.
2Measurement precision
If CT or MRI imaging studies are performed on emergency patients, then structural information is obtained, but the tests are time-consuming and patients' conditions deteriorate during waiting
Solution Approach 1:
The patent performs preliminary brain function assessment using portable EEG equipment at the point of care before patients are transferred to imaging facilities. This preliminary action provides immediate diagnostic information about brain function, allowing clinicians to make timely decisions without waiting for imaging studies, thus reducing time loss while maintaining detection accuracy.
Solution Approach 2:
The patent enables rapid EEG-based brain function assessment that can be completed in minutes, allowing clinicians to skip or delay time-consuming imaging studies for certain conditions. The quick functional assessment provides sufficient information for immediate triage and treatment decisions, rushing through the diagnostic process for time-critical cases.
3Measurement precision
If comprehensive brain imaging studies are conducted, then detailed structural information is obtained, but the cost increases and availability decreases
Solution Approach 1:
The patent uses inexpensive, disposable EEG electrodes and portable assessment equipment instead of expensive, fixed imaging infrastructure. This approach provides adequate brain function assessment capability at a fraction of the cost of CT or MRI, improving cost-effectiveness while maintaining necessary detection precision for emergency triage.
Solution Approach 2:
The patent substitutes expensive mechanical imaging systems with affordable electrical measurement technology. The EEG-based system provides functional brain assessment capability comparable to imaging for certain conditions, dramatically reducing costs while improving availability and ease of deployment in resource-limited settings.
4Ease of operation
If traditional clinical examination methods are used, then the assessment is simple and quick, but the objectivity and sophistication of brain function assessment is insufficient
Solution Approach 1:
The patent employs automated EEG signal processing and analysis algorithms that objectively interpret brain electrical activity without requiring expert manual interpretation. The system self-analyzes the recorded signals to provide quantitative measures of brain function, maintaining simplicity of operation while dramatically improving objectivity and measurement precision compared to traditional clinical exams.
