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

An improved osmotic sanitary collection bag with integrated moisture-sensing, antimicrobial, and detachable absorbent sponge features, enhancing user experience, comfort, and hygiene.

Background and Problem Solved

The original osmotic sanitary collection bag patent addressed the issue of unpredictable menstrual flow, but had limitations in terms of reusability, comfort, and antimicrobial properties. The new inventive concept solves these limitations by introducing advanced features that improve the overall user experience.

Detailed Description of the Inventive Concept

The enhanced osmotic sanitary collection bag comprises a moisture-sensing layer integrated into the absorbent sponge, which triggers an alert when the absorbent sponge reaches a predetermined level of saturation. Additionally, the absorbent sponge is treated with a hydrophobic coating to reduce fluid absorption and facilitate cleaning. The collection bag also features an integrated antimicrobial layer to reduce bacterial and fungal growth. Furthermore, the absorbent sponge is detachable and replaceable, allowing for easy cleaning and maintenance of the collection bag. The outer layer of the collection bag is breathable and flexible, conforming to the user's body to reduce irritation and discomfort.

Novelty and Inventive Step

The new claims introduce novel features that are not present in the original patent, including the moisture-sensing layer, hydrophobic coating, antimicrobial layer, detachable absorbent sponge, and breathable outer layer. These features provide a significant improvement over the original patent, making the enhanced osmotic sanitary collection bag more efficient, comfortable, and hygienic.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include variations in the moisture-sensing layer, such as using different materials or sensors. The antimicrobial layer could be replaced with alternative antimicrobial agents or coatings. The detachable absorbent sponge could be designed with different shapes or sizes to accommodate various user needs.

Potential Commercial Applications and Market

The enhanced osmotic sanitary collection bag has significant commercial potential in the feminine hygiene market, particularly among women who value comfort, convenience, and hygiene. The product could be marketed as a premium offering, targeting health-conscious consumers who are willing to pay for advanced features and improved user experience.
