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. 11,857,453.

Summary of the Inventive Concept

A comprehensive system for ostomy appliances, offering improved security, leakage prevention, and stoma monitoring, while providing modular customization and self-cleaning capabilities.

Background and Problem Solved

The original ostomy appliance patent addresses the need for a non-circular flange for mechanical attachment of a bag or pouch. However, it lacks features to prevent accidental detachment, reduce leakage, and monitor stoma health. The Enhanced Ostomy Appliance System solves these inherent limitations by introducing a safety lock, sealant application, integrated sensor, modular design, and self-cleaning properties.

Detailed Description of the Inventive Concept

The system comprises a mechanical attachment mechanism with a safety lock to prevent accidental detachment, ensuring a secure connection between the ostomy appliance and bag. A sealant application method reduces ostomy appliance leakage, while an integrated sensor detects changes in the stoma or surrounding skin, providing alerts to the patient or caregiver. The modular design allows for interchangeable faceplates and bags with different sizes and shapes to accommodate various stoma types and patient needs. Additionally, the self-cleaning ostomy appliance features a hydrophobic coating and a mechanism for releasing a cleaning solution, maintaining a hygienic environment.

Novelty and Inventive Step

The Enhanced Ostomy Appliance System introduces novel features that are not obvious from the original patent, including the safety lock, sealant application, integrated sensor, modular design, and self-cleaning properties. These features provide a significant improvement over the existing ostomy appliance, addressing the inherent limitations and offering a more comprehensive solution.

Alternative Embodiments and Variations

Alternative embodiments may include variations in the mechanical attachment mechanism, sealant application methods, sensor types, and modular design configurations. Additional features could be integrated, such as wireless connectivity, data analytics, or personalized alerts. The self-cleaning mechanism could be adapted for different ostomy appliance materials or sizes.

Potential Commercial Applications and Market

The Enhanced Ostomy Appliance System has significant commercial potential in the medical device industry, targeting patients with ostomies, caregivers, and healthcare providers. The system's improved security, leakage prevention, and stoma monitoring capabilities make it an attractive solution for those seeking a more comprehensive and convenient ostomy appliance.
