Ostomy Wafer Release Layer Segmentation for Precise Adhesive Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ostomy devices face challenges in secure attachment to the body, accurate positioning, and preventing leakage, as the adhesive layer can be damaged during initial attachment, leading to potential disposal of the device.
Innovation Solution
A body attachment wafer with a release layer divided along a line from the stoma opening to the periphery, featuring grip tabs that allow for precise positioning and easy removal of the release sheet without damaging the adhesive, ensuring accurate placement and minimizing skin irritation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the release sheet is removed completely before positioning, then the adhesive layer is exposed for attachment, but the adhesive force is damaged and positioning accuracy is lost
Solution Approach 1:
The release sheet is divided into multiple segments (first release sheet member and second release sheet member) separated by a dividing line. This segmentation allows the release sheet to be peeled back in a controlled manner, exposing only the necessary portion of the adhesive layer for positioning while keeping other portions protected, thus maintaining both positioning accuracy and adhesive force.
2Ease of operation
If the release sheet is made easy to remove, then positioning is facilitated, but the adhesive layer may be damaged during removal
Solution Approach 1:
The release sheet is segmented into multiple members that can be removed sequentially along a dividing line. This allows the user to peel back the release sheet in a controlled manner, making removal easy while preventing sudden or forceful removal that could damage the adhesive layer.
Solution Approach 2:
The dividing line acts as an intermediary element between the release sheet and the adhesive layer. It provides a predetermined separation path that facilitates easy removal of the release sheet while protecting the adhesive layer from damage during the removal process.
3Object-affected harmful factors
If the release sheet covers the entire adhesive layer, then protection is maximized, but positioning accuracy is reduced
Solution Approach 1:
The release sheet is divided into multiple members that can be selectively peeled back. This segmentation allows the user to expose only the specific area of the adhesive layer needed for positioning, maintaining protection over other areas while achieving positioning accuracy.
Solution Approach 2:
The release sheet members are pre-positioned and can be peeled back in advance of final attachment. This preliminary action allows the user to expose and position the adhesive layer accurately before completing the attachment, ensuring both protection and positioning precision.

AI summary
A body attachment wafer for an ostomy device is provided, which body attachment wafer has a stoma opening, and an adhesive layer. The adhesive layer is covered by a release layer, having an opening which corresponds to the stoma opening. The release layer is divided along at least one dividing line from the stoma opening to the periphery of the body attachment wafer, and the release sheet includes a first grip tab extending from the release sheet in the area of the at least one dividing line. The first grip tab is arranged to overlap the release sheet on the other side of the dividing line.
