Bacteria Formulation for Ostomy Odor Neutralization and Skin Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ostomy pouch systems produce odors due to insufficient odor neutralization by filters, leading to user discomfort and potential skin infections, and frequent product replacement causes inefficiency and skin irritation.
Innovation Solution
A bacteria formulation comprising odor-neutralizing bacteria, such as Thiobacillus sp., and probiotic bacteria, like Lactobacillus spp., is integrated into ostomy pouch systems and skin contacting adhesives to oxidize hydrogen sulfide and methyl mercaptan, providing antimicrobial protection and maintaining pH levels for effective odor neutralization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional ostomy pouch filters are used, then the pouch system can be manufactured, but the deodorizing effect is insufficient and costs are high
Solution Approach 1:
The patent changes the chemical composition parameters of the filter by incorporating specific bacteria (Pseudomonas putida, Bacillus subtilis, Streptomyces sp.) and their metabolic byproducts, transforming the filter from a passive physical barrier to an active biological deodorizing system that converts malodorous compounds into less odorous substances through bacterial metabolism
Solution Approach 2:
The patent creates a composite filter material combining bacterial cells, their metabolic byproducts, and traditional filter media, forming a multi-component system that leverages both biological deodorizing mechanisms and physical filtration to achieve superior odor neutralization at lower cost
2Object-affected harmful factors
If frequent cleansing and replacement of skin contacting products is performed, then body odors are minimized, but skin irritation occurs and time is consumed
Solution Approach 1:
The patent incorporates odor-neutralizing bacteria and antimicrobial probiotics into the skin contacting adhesive and pouch system, enabling continuous deodorizing and antimicrobial protection throughout the wear period without requiring frequent removal, cleansing, or replacement of the product
Solution Approach 2:
The bacteria and probiotics embedded in the product perform self-service deodorizing and antimicrobial functions autonomously during product use, neutralizing odors and preventing infections without requiring active user intervention such as frequent cleansing or product replacement
3Reliability
If skin contacting surfaces are frequently replaced, then infection risk is reduced, but product efficiency decreases
Solution Approach 1:
The patent incorporates antimicrobial probiotics (Lactobacillus spp., Lactococcus, Leuconostoc, Bifidobacterium) into the skin contacting adhesive and pouch system, providing long-lasting antimicrobial protection that extends product usability while maintaining infection prevention, thereby reducing the frequency of replacement needed
