Neurological Screening Device Using Retinal Scanning for Frontal Lobe Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for diagnosing and monitoring brain dysfunction, particularly after traumatic brain injuries, are invasive, time-consuming, and not readily available in high-risk environments, leading to delayed identification and increased risk of further injury.
Innovation Solution
A non-invasive neurological screening device that uses retinal scanning and oculomotor function measurements to assess frontal lobe function, incorporating cognitive tasks to stress the frontal lobe and measure eye fixation, binocularity, and saccadic movements for rapid and accurate evaluation of brain dysfunction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional clinical assessment methods are used to diagnose brain dysfunction, then diagnostic accuracy can be achieved, but the assessment process becomes lengthy and time-consuming
Solution Approach 1:
The patent extracts and isolates specific oculomotor functions (fixation stability, saccadic movements, binocularity) that serve as reliable indicators of frontal lobe function. By focusing measurement on these specific extracted parameters rather than进行全面 clinical assessment, the system achieves rapid screening while maintaining diagnostic relevance for identifying patients requiring further evaluation
Solution Approach 2:
The patent replaces traditional mechanical/neuropsychological testing methods with optical measurement systems that track eye movements using imaging technology. This substitution enables automated, objective measurement of oculomotor parameters without requiring lengthy clinical observation or patient performance of complex cognitive tasks
2Measurement precision
If comprehensive clinical assessment is performed to identify brain dysfunction, then accurate diagnosis can be made, but the assessment is not readily available in high-risk environments
Solution Approach 1:
The patent describes a self-contained screening device that performs all necessary functions autonomously - the system automatically captures images, tracks oculomotor parameters, compares results against normative data, and generates screening outcomes without requiring external clinical infrastructure or specialized personnel, enabling deployment in resource-limited high-risk environments
Solution Approach 2:
The patent creates a universal screening tool that can be deployed across multiple settings (sports facilities, military operations, clinical environments) and populations. The device integrates multiple functions - imaging, tracking, analysis, and reporting - into a single platform that adapts to different high-risk environments without requiring location-specific customization
3Loss of time
If rapid screening is implemented to quickly identify patients, then time loss is reduced, but measurement precision may be compromised
Solution Approach 1:
The patent establishes normative databases of oculomotor parameters obtained from healthy individuals before injury or illness. This preliminary action creates reference standards that enable rapid comparison and interpretation of screening results, allowing the system to provide accurate diagnostic information quickly without requiring lengthy assessment protocols

AI summary
A neurological screening device and method for assessing brain dysfunction of a subject including a projection apparatus configured to project an image onto retinas of a subject, detectors configured to capture light reflected from the retinas, the reflected light indicating a fixation of the eyes, a controller configured to generate baseline cognitive performance data based at least in part on a presence or absence of fixation, cause output of a plurality of assessment images on displays of the neurological screening device, the plurality of assessment images corresponding to a cognitive assessment configured to stress the frontal lobe of the subject, generate stressed cognitive performance data based at least in part on a presence or absence of fixation during the cognitive assessment, and determine brain dysfunction of the subject based at least in part on the baseline cognitive performance data and the stressed cognitive performance data.
