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. 11,857,402.

Summary of the Inventive Concept

A reusable osmotic sanitary collection bag system with improved absorbency, durability, antimicrobial properties, modularity, and integrated sensors to address the limitations of existing sanitary pads and provide users with a more efficient, safe, and hygienic experience.

Background and Problem Solved

The original osmotic sanitary collection bag patent, while providing a reusable solution for absorbing menstrual fluid, still has limitations in terms of absorbency, durability, and antimicrobial properties. The new inventive concept addresses these limitations by introducing enhancements that improve the overall performance and user experience of the osmotic sanitary collection bag.

Detailed Description of the Inventive Concept

The enhanced osmotic sanitary collection bag system comprises a porous membrane integrated into the absorbent sponge to increase fluid absorption capacity, a water-repellent coating to reduce wear and tear, an absorbent sponge infused with a combination of isopropyl alcohol and silver nanoparticles to kill bacteria and yeast cells, interchangeable absorbent sponge modules with varying absorption capacities for adapting to different user needs, and integrated moisture and temperature sensors to detect fluid leakage and alert the user to replace the bag. These enhancements work together to provide a more efficient, safe, and hygienic experience for users.

Novelty and Inventive Step

The new claims introduce novel and non-obvious improvements to the original osmotic sanitary collection bag patent, including the integration of a porous membrane, water-repellent coating, antimicrobial properties, modularity, and integrated sensors. These enhancements provide a significant advancement in the field of sanitary pads, offering users a more efficient, safe, and hygienic experience.

Alternative Embodiments and Variations

Alternative embodiments of the enhanced osmotic sanitary collection bag system could include different materials and designs for the porous membrane, water-repellent coating, and antimicrobial properties. Additionally, the system could be adapted for use in other applications, such as incontinence or wound care.

Potential Commercial Applications and Market

The enhanced osmotic sanitary collection bag system has significant commercial potential in the feminine hygiene and healthcare industries, offering a more efficient, safe, and hygienic solution for users. The system could be marketed as a premium product, targeting users who value convenience, safety, and hygiene.
