This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,580.

Summary of the Inventive Concept

This inventive concept integrates the patented Lactobacillus paracasei MG4272 strain-based composition with distinct technologies such as AI, IoT, blockchain, and new materials to create a more powerful system for detecting, treating, and preventing vaginal infections.

Background and Problem Solved

The original patent disclosed a composition comprising a cell-free supernatant of Lactobacillus paracasei MG4272 strain, which has antifungal and antimicrobial activity against Gardnerella vaginalis and Candida albicans. However, the original patent did not address the limitations of diagnosis, treatment, and prevention of vaginal infections. The new inventive concept solves this problem by combining the Lactobacillus paracasei MG4272 strain-based composition with distinct technologies to create a more comprehensive system.

Detailed Description of the Inventive Concept

The new inventive concept comprises four synergistic combinations: (1) an AI-powered diagnostic tool integrated with the Lactobacillus paracasei MG4272 strain-based composition for accurate detection of Gardnerella vaginalis and Candida albicans infections; (2) an IoT-enabled wearable device that monitors vaginal pH levels and temperature, alerting the user to take the composition when an infection is detected; (3) a blockchain-based system for tracking and verifying the origin and quality of the Lactobacillus paracasei MG4272 strain-based composition; and (4) a novel material comprising a matrix of nanofibers and the Lactobacillus paracasei MG4272 strain-based composition, which improves bioavailability and stability of the composition.

Novelty and Inventive Step

The new inventive concept is novel and non-obvious because it integrates the patented Lactobacillus paracasei MG4272 strain-based composition with distinct technologies, creating a more comprehensive system for detecting, treating, and preventing vaginal infections. The synergistic combinations of the new claims provide an unexpected advantage over the original patent, which did not address the limitations of diagnosis, treatment, and prevention of vaginal infections.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include integrating the Lactobacillus paracasei MG4272 strain-based composition with other distinct technologies such as machine learning algorithms, robotics, or nanotechnology. Variations of the inventive concept could include using different strains of Lactobacillus or combining the composition with other antimicrobial agents.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in the healthcare industry, particularly in the fields of women's health, infectious diseases, and medical diagnostics. The target market includes pharmaceutical companies, medical device manufacturers, and healthcare providers.
