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. 11,857,454.

Summary of the Inventive Concept

The present inventive concept discloses novel ostomy faceplates designed to provide enhanced comfort, reduced skin irritation, and improved compatibility with skin creases, rolls, or folds. The inventive concept addresses the limitations of existing ostomy appliances by introducing adjustable flanges, tapered edges, and modular designs that cater to individual patient needs.

Background and Problem Solved

The original patent disclosed ostomy faceplates configured for use in close proximity with creases, rolls, or folds. However, these faceplates may not provide optimal comfort and skin compatibility for all patients. The present inventive concept solves this problem by introducing direct improvements and enhancements to the original design, enabling a more comfortable and efficient ostomy care experience.

Detailed Description of the Inventive Concept

The inventive concept comprises a system for ostomy care featuring an adjustable flange with a straight edge, designed to adapt to various skin creases, rolls, or folds. Additionally, the concept includes a method for providing an ostomy appliance in close proximity with a skin crease, roll, or fold, by aligning a substantially straight edge of the appliance with the skin crease, roll, or fold. The ostomy faceplate is further enhanced with a tapered edge, reducing skin irritation and discomfort. A modular ostomy appliance system is also disclosed, comprising interchangeable flanges with different edge geometries, allowing for customization to individual patient needs. Furthermore, a self-adhering ostomy faceplate with a straight edge is designed, featuring an adhesive specifically formulated for use on skin creases, rolls, or folds.

Novelty and Inventive Step

The present inventive concept introduces novel features that distinguish it from the original patent. The adjustable flange, tapered edge, modular design, and self-adhering faceplate with a straight edge provide a non-obvious solution to the problem of skin compatibility and comfort in ostomy care. These features collectively contribute to a more efficient, comfortable, and patient-centric ostomy care experience.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept may include ostomy faceplates with curved or angled edges, or those featuring a combination of adjustable and tapered edges. The modular design could be extended to incorporate different materials, shapes, or sizes of flanges, catering to diverse patient needs. Additionally, the self-adhering faceplate could be adapted for use with various types of ostomy appliances or pouches.

Potential Commercial Applications and Market

The enhanced ostomy faceplates disclosed in the present inventive concept have significant commercial potential in the medical device industry, particularly in the ostomy care market. The target market includes patients with ileostomies, colostomies, or urostomies, as well as healthcare professionals and caregivers involved in ostomy care. The inventive concept's focus on comfort, skin compatibility, and customization is expected to resonate with patients and healthcare providers, driving adoption and market growth.
