Turmeric-Treated Filter Paper for Respiratory Pathogen Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical testing systems are costly, require laboratory analysis, and are not suitable for home use, lacking a simple, economical, drug-free method to detect respiratory pathogens that may induce illness.
Innovation Solution
A tissue tester system using a filter paper sheet treated with a solution of turmeric and alcohol, which changes color when exposed to respiratory secretions, providing a rapid indication of illness through a color change from yellow to brown.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If laboratory analysis and expensive equipment are used, then detection accuracy is improved, but cost and accessibility deteriorate
Solution Approach 1:
The patent extracts the detection function from complex laboratory equipment and implements it using simple filter paper treated with turmeric and alcohol. The color-changing indicator on the filter paper performs the detection function that previously required expensive instruments, making the test portable and accessible for home use while maintaining adequate detection accuracy for respiratory pathogen identification.
Solution Approach 2:
The invention uses disposable filter paper strips treated with inexpensive natural indicators (turmeric and alcohol) instead of expensive, complex, and potentially reusable laboratory equipment. This approach reduces cost significantly while providing sufficient detection capability for the intended purpose of identifying respiratory illnesses at home.
2Reliability
If laboratory testing is used, then diagnostic reliability is improved, but time and cost increase
Solution Approach 1:
The filter paper is pre-treated with turmeric and alcohol solution before use, creating a ready-to-test device that can be applied immediately to respiratory secretions. This preliminary preparation eliminates the need for complex in-lab processing and allows for rapid on-site testing, reducing time loss while maintaining diagnostic reliability through the color-change indication.
3Adaptability or versatility
If complex testing systems are used, then detection capability is improved, but ease of operation deteriorates
Solution Approach 1:
The test device is designed to be self-sufficient and self-interpreting. The filter paper with turmeric-alcohol treatment automatically detects respiratory pathogens through color change without requiring external laboratory equipment or complex procedures. Users can self-administer the test by simply applying the indicator to respiratory secretions and observing the color change, making it easy to operate while maintaining adequate detection capability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables a self-administered, immediate, and cost-effective method for individuals to determine the presence of respiratory pathogens, facilitating early detection of illness without the need for expensive equipment or laboratory analysis.
Implementation Method 1
the at least a portion of the tester changes color when exposed to respiratory secretions containing a pathogen. In another aspect the color change is from a yellow hue to a brown hue.
Data Source
AI summary
A tissue tester for providing an indication of the presence of disease including a first paper tissue sheet; and a filter patch treated with a color changing indicator affixed to the first paper tissue sheet. The tester may also consist of a single sheet of filter paper treated with a solution of turmeric and alcohol. The color indicator changes from yellow to brown when disease is indicated in respiratory secretions.
