Low pH Inhaled Fluid for Respiratory Pathogen Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for respiratory illnesses caused by infectious pathogens, such as viral, bacterial, and fungal pathogens, lack a broad-spectrum antimicrobial therapy that is effective across multiple pathogens, including antibiotic-resistant strains and emerging variants like SARS-CoV-2, and are often costly, require extensive development time, and may have systemic side effects.
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, providing a localized and tolerable antiseptic effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a broad-spectrum antimicrobial therapy is developed to be effective across multiple pathogens including antibiotic-resistant strains and emerging variants, then the efficacy against diverse pathogens is improved, but the development time and cost increase significantly
Solution Approach 1:
The patent applies universality by developing a single inhaled acidic composition that functions as a broad-spectrum antimicrobial agent effective against multiple pathogen types including viruses, bacteria, and fungi. The acidic pH (less than 3.0) provides universal antimicrobial activity across diverse pathogens without requiring pathogen-specific formulations, thereby reducing development time while maintaining broad efficacy.
Solution Approach 2:
The patent utilizes parameter changes by adjusting the pH of the inhaled composition to be less than 3.0, which creates an environment that is effective against a wide range of pathogens. This parameter adjustment (pH level) enables the composition to demonstrate broad-spectrum antimicrobial activity without requiring extensive development for each specific pathogen variant.
2Reliability
If inhaled acidic compositions with pH less than 3.0 are administered to achieve broad-spectrum antimicrobial effect, then the antimicrobial efficacy is improved, but the potential toxicity to respiratory tract tissue worsens
Solution Approach 1:
The patent applies local quality by delivering the acidic composition directly to the site of infection in the respiratory tract through inhalation. The acidic pH (less than 3.0) is maintained locally at the infection site where it exerts antimicrobial effect, while the composition is designed to be transient and non-systemic, minimizing exposure and potential toxicity to healthy respiratory tract tissues.
Solution Approach 2:
The patent converts the potentially harmful acidic pH into a beneficial antimicrobial agent. The acidity that could be toxic is instead utilized as the mechanism of action to kill pathogens. The composition is formulated with pharmaceutically acceptable acids and is designed to be transient, allowing the harmful acidic property to be harnessed for therapeutic benefit while minimizing damage to host tissues through controlled delivery and rapid clearance.
3Object-affected harmful factors
If inhaled compositions are used to provide localized treatment with minimal systemic effects, then the safety profile is improved, but the ability to treat deep respiratory tract infections worsens
Solution Approach 1:
The patent applies dynamics by utilizing the natural respiratory dynamics (breathing patterns, airflow, and mucociliary clearance) to enhance the distribution and penetration of the inhaled acidic composition throughout the respiratory tract. The composition leverages inhalation dynamics to reach deep lung regions while maintaining localized action, and utilizes exhalation and clearance mechanisms to limit systemic absorption, thereby achieving both deep coverage and minimal systemic effects.
