Low pH Acidic Fluid for Respiratory Pathogen Inactivation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for respiratory illnesses caused by viral, bacterial, and fungal pathogens are often pathogen-specific, costly, and may lead to antibiotic resistance, with a need for a broad-spectrum antimicrobial therapy that is safe, effective, and easily accessible, especially for emerging variants like SARS-CoV-2 and antibiotic-resistant strains.
Innovation Solution
A method involving the administration of a pharmaceutically acceptable fluid with a pH less than 3.0, containing inorganic or organic acids, directly into the respiratory tract to treat or prevent respiratory illnesses by reducing pathogen load, which can be administered through inhalation using devices like nebulizers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pathogen-specific therapeutics are used, then treatment effectiveness against specific pathogens is improved, but development time and cost increase, and accessibility to emerging variants is reduced
Solution Approach 1:
The patent applies universality by developing a broad-spectrum antimicrobial composition that can treat multiple types of respiratory pathogens (viral, bacterial, and fungal) simultaneously, rather than creating separate pathogen-specific therapies. This allows a single formulation to address current and emerging variants without requiring separate development cycles for each pathogen type.
Solution Approach 2:
The patent utilizes parameter changes by adjusting the pH of the composition to a highly acidic range (pH 0.5-2.0) to achieve broad-spectrum antimicrobial activity. This parameter modification enables the composition to effectively inactivate diverse pathogens including enveloped and non-enveloped viruses, bacteria, and fungi through a common mechanism of action.
2Adaptability or versatility
If broad-spectrum antimicrobial therapy is used, then coverage against multiple pathogens is improved, but safety and toxicity concerns increase
Solution Approach 1:
The patent applies local quality by designing a composition that exerts its broad-spectrum antimicrobial effect locally at the site of infection in the respiratory tract, rather than systemically throughout the body. The acidic pH composition is administered via inhalation or nasal spray, concentrating the antimicrobial action where pathogens are present while minimizing exposure to healthy tissues and systemic absorption.
Solution Approach 2:
The patent uses an intermediary approach by formulating the acidic pH composition with buffers and stabilizing agents that moderate the acidity to protect host tissues while maintaining pathogen inactivation efficacy. The composition includes ingredients that allow the acidic pH to selectively damage pathogens without causing excessive harm to human respiratory tissues.
3Reliability
If advanced medical treatments are used, then treatment efficacy is improved, but accessibility and cost increase
Solution Approach 1:
The patent applies this principle by developing a simple, stable composition that can be administered through basic delivery devices without requiring complex infrastructure. The formulation is designed to be shelf-stable and easy to store, enabling distribution to remote and resource-limited settings where advanced medical facilities are unavailable.
Solution Approach 2:
The patent utilizes self-service by creating a composition that leverages the body's own immune system and natural respiratory functions to achieve treatment. The acidic pH composition works synergistically with host defenses, requiring minimal medical intervention and enabling patients to self-administer treatment through simple inhalation or nasal spray without needing specialized medical equipment or procedures.
