Respiratory Virus Detection Mask with Color-Changing Filter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current respiratory viral pathogen testing is inefficient due to high costs, resource utilization, and time delays, particularly in identifying asymptomatic carriers, which contributes to disease spread during pandemics, as most treatments for respiratory viruses do not change with specific identification and existing methods are not effective for screening asymptomatic individuals.
Innovation Solution
A rapid testing mechanism using a face mask with a filter material impregnated with a pathogen binding adsorptive reagent, where exhaled breath particles are captured, and positive or negative test results are indicated through a transparent membrane, allowing for external visualization of results without the need for expensive technology or labor-intensive processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional viral testing methods are used, then specific virus identification is achieved, but cost and resource utilization increase significantly
Solution Approach 1:
The patent extracts only the essential function of virus detection from complex conventional testing methods. By using a simple filter material with pathogen binding adsorptive reagent, it isolates the core detection capability while removing unnecessary complexity, expensive reagents, and elaborate procedures, thereby reducing cost while maintaining detection functionality.
Solution Approach 2:
The invention employs a disposable filter mask as the testing device, which is inexpensive to manufacture and use. The filter material with adsorptive reagent is designed for single-use, eliminating the need for expensive equipment, complex sample processing, and expensive confirmatory testing, thus dramatically reducing the quantity of resources consumed per test.
2Measurement precision
If conventional testing methods are used, then specific virus identification is achieved, but time delay until test result increases
Solution Approach 1:
The pathogen binding adsorptive reagent is pre-loaded onto the filter material during manufacturing. This preliminary preparation eliminates the need for complex sample processing, reagent mixing, and equipment setup at the time of testing. Users simply wear the mask and results are obtained rapidly, dramatically reducing the time delay from sample collection to result.
Solution Approach 2:
The invention replaces complex mechanical testing systems (centrifuges, PCR machines, microtiter plates) with a passive chemical adsorption system. The adsorptive reagent automatically binds pathogens from breath particles as they pass through the filter, eliminating the need for time-consuming mechanical processing steps and enabling rapid results.
3Measurement precision
If conventional testing methods are used, then specific virus identification is achieved, but device complexity increases
Solution Approach 1:
The filter mask serves multiple functions simultaneously: it acts as both a protective mask and a diagnostic testing device. The same filter material that protects the wearer also contains the pathogen binding reagent for virus detection. This multi-functionality eliminates the need for separate testing equipment, sample collection devices, and result analysis systems, thereby reducing overall device complexity.
Solution Approach 2:
The invention uses color-changing indicators embedded in the filter material to provide visual test results. When the pathogen binding reagent reacts with respiratory viral pathogens, the indicator changes color, providing an immediate visual readout. This eliminates the need for complex result analysis equipment, trained technicians, and elaborate reporting systems, dramatically simplifying the overall testing mechanism.
4Measurement precision
If conventional testing methods are used, then specific virus identification is achieved, but ease of operation decreases
Solution Approach 1:
The filter mask performs self-testing through passive adsorption of pathogens from the wearer's breath. The pathogen binding reagent automatically captures viruses as the user breathes normally, and the color-changing indicator automatically signals results. This self-service mechanism eliminates the need for trained technicians, complex sample handling procedures, and elaborate testing protocols, making the test as easy to operate as wearing a mask.

Function Achieved in This Case
This solution provides a low-cost, sensitive, and qualitative method for detecting respiratory viral pathogens, enabling quick identification of carriers, reducing disease spread, and can be deployed in resource-poor settings or for point-of-care testing, with results visible externally for easy interpretation.
Implementation Method 1
At least a portion of the filter material includes a pathogen binding adsorptive reagent positioned between an internal layer and an external layer of the filter material
Data Source
AI summary
A rapid testing mechanism for respiratory viral pathogens includes a filter material, which includes a pathogen binding adsorptive reagent, positioned to capture exhaled breath particles from a respiratory tract. When the exhaled breath particles pass through the filter material, the following occur: when the binding adsorptive reagent reacts, a positive test for respiratory viral pathogens is indicated by the filter material; and when the pathogen binding adsorptive reagent does not react, a negative test is indicated. A transparent membrane makes the positive or negative test indication visible through the external layer of the filter material and, thus, visible to the external environment. For privacy, however, a cover over the transparent membrane may be movable between open and closed positions.
