Wound Closure Release Liner Tape for Controlled Adhesive Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
New users may improperly handle medical devices for closing wounds or incisions, causing the adhesive-backed anchoring members to stick to each other or to the patient's skin at undesired positions, rendering the device unusable.
Innovation Solution
The medical device includes first and second adhesive-backed anchoring members with release liners and a release liner tape that maintains the relative position of the components, allowing for proper removal of the release liners and preventing inadvertent sticking, while also featuring indicia for user guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the release liner is removed from the adhesive-backed anchoring members, then the anchoring members can be manipulated and positioned freely, but the adhesive-backed surfaces may inadvertently stick to each other or to the patient's skin at undesired positions
Solution Approach 1:
The release liner is divided into multiple segments: a first release liner portion and a second release liner portion that can be separately removed. This segmentation allows the user to remove one portion at a time, maintaining control over the adhesive exposure and preventing inadvertent sticking while enabling gradual manipulation and positioning of the anchoring members.
Solution Approach 2:
The medical device is pre-configured with the release liner segments and holding indicia in specific positions before use. The holding indicia are preliminarily positioned to guide the user's fingers for proper grasping and manipulation. This preliminary arrangement ensures that even inexperienced users can correctly manipulate the anchoring members without causing inadvertent adhesion.
2Ease of operation
If the release liner is completely removed before application, then the anchoring members can be freely manipulated, but inexperienced users may lose track of the correct positioning and rendering the device unusable
Solution Approach 1:
The holding indicia serve as an intermediary element between the release liner and the user's fingers. These indicia provide visual and tactile guidance, mediating the interaction between the user and the medical device. By grasping the holding indicia, users are guided to hold the device in the correct orientation, simplifying the handling process and preventing errors even for inexperienced users.
Solution Approach 2:
The medical device is designed to be self-guiding through the holding indicia and segmented release liner structure. The device itself provides the guidance mechanisms needed for proper manipulation, eliminating the need for external instructions or complex handling procedures. The holding indicia automatically guide the user's fingers to the correct positions, making the device self-explanatory and easy to use.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution ensures proper application and closure of wounds or incisions by maintaining component positioning and preventing unintended adhesion, making the device usable even for inexperienced users.
Implementation Method 1
a first release liner removably adhered to a first adhesive-backed surface of the first component
Implementation Method 2
The release liner tape may be removably coupled to the release liners and/or the pulling element
