Enhanced Ostomy Faceplates for Improved Skin Compatibility
Legal Citation
Summary of the Inventive Concept
This inventive concept introduces advanced ostomy faceplates designed to accommodate various skin creases, rolls, and folds, ensuring a secure seal and reducing irritation. The novel designs and materials improve user comfort, minimize leakage, and provide a more personalized fit.
Background and Problem Solved
The original patent, 'Ostomy faceplates configured for use in close proximity with creases, rolls, or folds', addressed the need for ostomy appliances to be used near skin creases. However, the existing design had limitations in terms of adaptability to different skin types and crease patterns. The new inventive concept solves this problem by introducing adjustable, modular, and self-healing features that cater to diverse skin geometries.
Detailed Description of the Inventive Concept
The enhanced ostomy faceplates comprise an adjustable flange edge that conforms to a patient's skin crease, roll, or fold, ensuring a secure seal and reducing irritation. The modular design allows for interchangeable faceplates with different edge geometries, accommodating various skin types and crease patterns. The self-healing adhesive flange repairs minor damage, maintaining a secure seal even in the presence of skin creases, rolls, or folds. Furthermore, the personalized ostomy system enables customization of faceplates with patient-specific edge geometries, determined by scanning the patient's skin crease, roll, or fold.
Novelty and Inventive Step
The new claims introduce novel features that improve upon the original patent's design, including adjustable flanges, modular interchangeability, self-healing adhesives, and personalized customization. These advancements provide a more comfortable, efficient, and effective ostomy solution.
Alternative Embodiments and Variations
Alternative embodiments may include ostomy faceplates with dynamic edge adjustment, smart sensors for real-time skin monitoring, or biocompatible materials with enhanced skin compatibility. Variations may also include different faceplate shapes, sizes, or materials to accommodate diverse user needs.
Potential Commercial Applications and Market
The enhanced ostomy faceplates have significant commercial potential in the medical device industry, particularly in the areas of wound care, ostomy management, and patient comfort. The target market includes healthcare providers, medical device manufacturers, and patients requiring ostomy appliances.
