Enhanced Ostomy Appliance Attachment System
Legal Citation
Summary of the Inventive Concept
A novel ostomy appliance attachment system that improves compatibility, security, and customization for patients with ostomies, addressing limitations of existing ostomy appliances.
Background and Problem Solved
The original ostomy appliance patent provides a non-circular flange for mechanical attachment of a bag or pouch. However, it lacks features to ensure precise cutting of drape material, secure attachment, and stoma protection. The new inventive concept solves these limitations by introducing a drape-cutting channel, straight edge alignment, tapered edge protection, modular faceplates, and customizable attachment methods.
Detailed Description of the Inventive Concept
The enhanced ostomy appliance attachment system comprises a drape-cutting channel integrated into the ostomy faceplate, allowing for precise cutting of drape material. The faceplate features a non-circular flange with at least one substantially straight edge, enabling secure attachment to NPWDs. Additionally, the system includes a tapered edge to facilitate overlapping by a drape material or other protective covering, reducing irritation and promoting healing. The modular design allows for interchangeable faceplates with varying channel configurations, ensuring optimal interaction with specific NPWDs. The system also enables customization through the selection of an ostomy faceplate with a non-circular flange having at least one substantially straight edge, and attaching it to an NPWD using a securement mechanism.
Novelty and Inventive Step
The new claims introduce a drape-cutting channel, straight edge alignment, tapered edge protection, modular faceplates, and customizable attachment methods, which are not present in the original patent. These features provide a non-obvious solution to the limitations of existing ostomy appliances, enhancing compatibility, security, and customization for patients with ostomies.
Alternative Embodiments and Variations
Alternative embodiments may include adjustable drape-cutting channels, interchangeable securement mechanisms, or integrated sensors to monitor stoma health. Variations of the modular faceplate design could include different channel configurations, materials, or sizes to accommodate various NPWDs and patient needs.
Potential Commercial Applications and Market
The enhanced ostomy appliance attachment system has significant commercial potential in the medical device industry, particularly in the ostomy care market. The system's improved compatibility, security, and customization features address the needs of patients with ostomies, offering a competitive advantage in the market. Potential target industries include healthcare providers, medical device manufacturers, and ostomy care suppliers.
