Intravaginal Carbon Mesh Insert for Localized Infection and Odor Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional treatments for vaginal infections like bacterial vaginosis (BV), herpes simplex virus (HSV), and toxic shock syndrome (TSS) often disrupt the vaginal microbiome and contribute to antimicrobial resistance, necessitating a localized, biocompatible, and multifunctional device that addresses odor, infection, and microbial imbalance without compromising mucosal health.
Innovation Solution
An intravaginal apparatus with a multi-layered structure containing porous carbonaceous materials for odor adsorption and therapeutic delivery, featuring a flexible body with mesh openings for fluid exchange, and optional therapeutic agents encapsulated within a carbon matrix for controlled release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional systemic antibiotics or antivirals are used to treat vaginal infections, then infection treatment effectiveness is improved, but vaginal microbiome balance deteriorates and antimicrobial resistance increases
Solution Approach 1:
The patent extracts the therapeutic function from systemic administration and localizes it to the vaginal site through a tampon device. The device extracts only the necessary antimicrobial action at the local level, avoiding systemic side effects and microbiome disruption while maintaining treatment effectiveness for vaginal infections.
Solution Approach 2:
The patent applies local quality by delivering therapeutic agents directly to the vaginal site through a locally inserted tampon device. This localized delivery ensures high concentration of treatment at the infection site while minimizing exposure to the rest of the body, thereby preserving overall microbiome balance and reducing antimicrobial resistance development.
2Object-generated harmful factors
If porous carbonaceous materials are used for odor adsorption, then odor compound removal is improved, but device structural complexity increases
Solution Approach 1:
The patent directly applies porous carbonaceous materials as the core functional component of the tampon device. These porous structures provide high surface area for adsorbing odor-causing compounds and pathogens. The complexity is managed by integrating these materials into a simple tampon form factor, combining multiple functions (adsorption, drug delivery, structural support) into a single unified device rather than separate components.
Solution Approach 2:
The patent merges multiple functions into a single tampon device: odor adsorption through porous carbonaceous materials, therapeutic agent delivery through encapsulation in the carbon matrix, and structural support through the tampon body. This consolidation simplifies the overall device architecture while achieving multiple therapeutic goals simultaneously.
3Manufacturing precision
If therapeutic agents are encapsulated within carbon matrix for controlled release, then treatment precision is improved, but manufacturing complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-encapsulating therapeutic agents within the carbon matrix during the manufacturing process. This pre-encapsulation establishes controlled release characteristics before the device is used, allowing the drug to be released in a controlled manner upon contact with vaginal fluids or specific pH conditions, thereby achieving treatment precision without requiring complex active control mechanisms during use.
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
The apparatus effectively adsorbs vaginal odor compounds and pathogens while preserving mucosal integrity and microbiota balance, providing localized treatment and prevention of infections.
Implementation Method 1
The device includes one or more openings, optionally fitted with mesh guards, to facilitate fluid exchange and enable adsorption of odor-causing compounds and pathogens. In some embodiments, the insertable material comprises a porous carbonaceous substance, which may be unbound, freely associating, or embedded within a matrix. These materials may be configured to selectively adsorb volatile amines, sulfur compounds, and microbial toxins.
