Ostomy Pressing Ring for Uniform Adhesive Seal Around the Stoma
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Achieving a consistent and uniform seal between ostomy pouches and the skin is challenging due to inconsistent manual finger pressure, leading to premature detachment, leakage, and frequent pouch replacements, affecting both patients and healthcare providers.
Innovation Solution
A handheld tool with a contoured pressing ring and ergonomic handle applies uniform pressure to the adhesive surface surrounding the stoma, accommodating various stoma dimensions and adhesive configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual finger pressure is used to apply adhesive, then the application process is simple and requires no additional tools, but the pressure is inconsistent leading to weak or uneven adhesion
Solution Approach 1:
The patent introduces a pressing tool as an intermediary device between the user's hand and the adhesive barrier. This tool mediates the pressure application process by providing a structured interface (pressing surface) that distributes force uniformly across the adhesive area, eliminating the inconsistency of direct finger pressure while maintaining ease of use through simple manual operation.
Solution Approach 2:
The pressing tool changes the pressure distribution parameter from concentrated and variable (manual finger pressure) to uniform and controlled (through the pressing surface). The tool's design ensures that pressure is evenly distributed across the adhesive barrier, transforming the pressure application from an inconsistent manual process to a standardized mechanical action.
2Reliability
If uniform pressure is applied to the adhesive barrier, then seal reliability and wear time are improved, but the application process requires additional tools and steps
Solution Approach 1:
The pressing tool is designed with a pressing surface that matches the specific geometry of the adhesive barrier and stoma area. This local customization ensures that pressure is applied precisely where needed (on the adhesive barrier surrounding the stoma) without requiring complex multi-component systems. The tool's shape is tailored to the application site, providing effective pressure distribution while maintaining simplicity.
Solution Approach 2:
The pressing tool can be implemented as a disposable or single-use component, eliminating the need for complex sterilization and maintenance systems. This approach trades the longevity of reusable tools for the simplicity and reliability of disposable ones, reducing device complexity while ensuring consistent performance for each application.
3Manufacturing precision
If the pressing tool is designed to fit specific stoma dimensions, then adhesion uniformity is improved, but the device loses versatility across different patient anatomies
Solution Approach 1:
The pressing tool is designed with universal features that allow it to adapt to different stoma sizes and adhesive barrier configurations. The pressing surface geometry is configured to work effectively across a range of dimensions, and the tool can be used with various ostomy appliance types (convex, flat, contoured), making it a multi-functional solution that maintains precision while ensuring broad applicability.
Applied Scientific Principles
