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. 11,857,455.

Summary of the Inventive Concept

A reusable menstrual discharge collection device with improved features, including antimicrobial coating, real-time fluid detection, modular design, and optimized manufacturing, enhancing user experience, safety, and efficiency.

Background and Problem Solved

The original patent disclosed a reusable menstrual disc-shaped device with dual durometer materials. However, it lacked features that addressed bacterial growth, fluid monitoring, and ease of maintenance. The new inventive concept builds upon the original patent's foundation, addressing these limitations and providing a more comprehensive solution for users.

Detailed Description of the Inventive Concept

The advanced reusable menstrual discharge collection device features a dual-durometer rim and catch, with the catch coated with an antimicrobial material to reduce bacterial growth. The device is manufactured using a mold with a temperature control system to optimize the curing process of the polymeric material. Additionally, the device includes a built-in sensor to detect the amount of menstrual fluid collected, providing real-time feedback to the user. The device's modular design allows users to replace worn-out components, extending the lifespan of the device. A combination of ultrasonic cleaning and UV light disinfection ensures effective sanitization of the device.

Novelty and Inventive Step

The new inventive concept introduces several novel features that distinguish it from the original patent. The antimicrobial coating, real-time fluid detection, and modular design are non-obvious improvements that enhance the device's functionality and user experience. The optimized manufacturing process and combination of ultrasonic cleaning and UV light disinfection further differentiate the new inventive concept from the prior art.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include varying the type of antimicrobial material used, incorporating different sensor technologies, or modifying the modular design to accommodate different user preferences. Additionally, the device could be adapted for use in various applications beyond menstrual discharge collection, such as incontinence management or wound care.

Potential Commercial Applications and Market

The advanced reusable menstrual discharge collection device has significant commercial potential in the feminine hygiene market, with potential applications in the healthcare industry. The device's enhanced features and improved user experience position it for success in a market seeking innovative, safe, and efficient solutions for menstrual management.
