Periocular Air Control for Dry Eye Diagnostics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for diagnosing and grading dry eye and other ophthalmic conditions are inconvenient and costly, as they are highly dependent on variable environmental humidity and temperature, leading to inconsistent diagnostic outcomes.
Innovation Solution
A headset with integrated humidity and temperature monitoring and control systems, including sensors, a processor, and adjustable air conditioning components (humidifier, dehumidifier, heater, and cooling element) to maintain standardized conditions for accurate ophthalmic testing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional ophthalmic testing methods are used, then diagnostic procedures can be performed, but the results are highly variable and inconsistent due to uncontrolled environmental humidity and temperature
Solution Approach 1:
The system actively changes and controls the environmental parameters (humidity and temperature) within the testing chamber to standardized values, transforming the uncontrolled variable environment into a controlled one. This allows consistent diagnostic results by ensuring testing always occurs under identical environmental conditions.
Solution Approach 2:
The invention introduces an intermediary testing chamber that separates the patient from the uncontrolled external environment. This intermediate space with controlled climate acts as a mediator, allowing accurate measurements without the interfering effects of ambient environmental variations.
2Measurement precision
If comprehensive ophthalmic testing is performed, then accurate diagnosis can be achieved, but the process is time-consuming and costly
Solution Approach 1:
The system performs self-characterization by automatically measuring and controlling the environmental conditions within the testing chamber. The climate control system self-regulates humidity and temperature without requiring manual intervention, enabling rapid setup and consistent reproduction of testing conditions.
Solution Approach 2:
The system performs preliminary characterization of the testing environment before actual ophthalmic measurements are taken. By pre-establishing and verifying controlled conditions (humidity, temperature, airflow) in advance, the system ensures measurement accuracy while reducing the time needed during the actual diagnostic procedure.
3Adaptability or versatility
If environmental conditions are not controlled, then testing can be performed in any location, but diagnostic results vary significantly with changes in humidity and temperature
Solution Approach 1:
The testing chamber serves as an intermediary device that can be transported to different locations while maintaining controlled environmental conditions. This allows the system to adapt to various testing locations (clinics, labs, mobile units) without sacrificing measurement precision, as the chamber creates its own controlled environment regardless of external surroundings.
