Wound Closure Strip Handling With Release Liner Mediation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wound closure devices with multiple release liners are difficult to handle, leading to adhesive contamination and compromised sterility due to the need to grasp the adhesive surface, requiring high dexterity and often causing misalignment during application.
Innovation Solution
A wound closure device with adhesive extending through open areas in the closure layer, allowing a substrate layer to contact the adhesive on the non-wound facing surface, enabling easy handling and reducing the need to touch the adhesive surface, with a release liner serving as a handle to facilitate application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user grasps the edge regions of the strip to position and apply it, then the strip can be manually positioned and applied to the skin, but the adhesive on the wound facing surface is inadvertently touched and contaminated, compromising sterility and bonding strength
Solution Approach 1:
A release liner is introduced as an intermediary element between the user's fingers and the adhesive surface. The release liner serves as a protective barrier that prevents direct contact between the user's hands and the adhesive on the wound facing surface, thereby maintaining sterility and bonding strength while still allowing manual positioning and application of the strip
2Ease of operation
If the user grasps the edge regions of the strip to apply it, then the strip can be positioned, but a high level of dexterity is required, especially for smaller sized wounds and closure strips
Solution Approach 1:
The release liner acts as a mediator that provides a larger, more accessible surface for the user to grasp and manipulate. Instead of requiring precise finger placement on small edge regions of the strip, the user can comfortably hold and position the release liner, which then translates this control to the underlying closure strip, reducing the dexterity requirement
3Ease of operation
If multiple sections of release liners are incorporated onto the adhesive, then handling issues are overcome and the strip can be controlled during use, but the device complexity increases
Solution Approach 1:
Instead of incorporating multiple sections of release liners onto the adhesive as in prior art, this invention extracts the release liner function to a separate, removable component. The release liner is applied to the wound facing surface and then removed before application, leaving only the necessary adhesive exposed. This simplifies the device structure while maintaining ease of handling
