Adhesive Eyelid Closure Patch With Non-Adhesive Tab for Gentle Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adhesive eyelid closure solutions for preventing eye opening during surgery suffer from poor conformability to the human eye's physiological contours, causing skin damage, discomfort, and difficulty in application and removal, while also failing to maintain eye moisture and visibility during procedures.
Innovation Solution
An adhesive eyelid closure article with a support layer and pressure-sensitive adhesive, featuring a non-adhesive tab area defined by recesses in the outer circumferential portion, providing excellent conformability, gentle adhesion, and ease of application and removal, while maintaining eye moisture and visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive tape is applied across upper and lower eyelids to prevent eye opening, then eye protection during surgery is improved, but skin damage and eyelash plucking occur due to excessive adhesion
Solution Approach 1:
The adhesive patch incorporates a non-adhesive tab area that extends beyond the eyelid margins, creating a local distinction between adhesive and non-adhesive zones. This allows the adhesive portion to secure the patch in place while the non-adhesive tab prevents excessive adhesion to skin and eyelashes, resolving the contradiction between reliable eye protection and skin damage prevention
Solution Approach 2:
The adhesive patch is segmented into distinct functional zones: an adhesive coated area for securing the patch, a non-adhesive tab area for gentle removal, and a central eye coverage area. This segmentation allows each zone to perform its specific function without interfering with other zones, preventing both skin damage and ensuring reliable protection
2Ease of operation
If opaque and transparent eye patches are used to reduce patient discomfort, then patient comfort is improved, but conformability to physiological contours and gentleness to skin are insufficient
Solution Approach 1:
The adhesive patch utilizes a flexible, thin film support layer that can conform to the curved physiological contours of the eye and surrounding skin. This flexible structure maintains patient comfort while adapting to the unique anatomy of each eye, resolving the contradiction between comfort and conformability
Solution Approach 2:
The adhesive patch is designed with a curved, contoured shape that matches the spherical geometry of the eye. This curvature enables the patch to conform naturally to the eye's surface and surrounding contours, improving both conformability and patient comfort simultaneously
3Reliability
If adhesive tape is used to secure eyelids, then eye closure is maintained, but application and removal operations become difficult due to excessive adhesion
Solution Approach 1:
The adhesive patch creates a local distinction between the adhesive coated area for secure attachment and the non-adhesive tab area for easy handling. This allows the patch to maintain reliable eye closure while enabling simple application and removal operations through the non-adhesive tab

AI summary
The disclosed adhesive eyelid closure article has a support layer and a pressure sensitive adhesive on the support layer. The support layer defines a main body and a non-adhesive tab area. The support layer has a central portion and an outer circumferential portion. The non-adhesive tab area is delimited by two recesses located in the outer circumferential portion of the support layer. The support layer has a first major surface and a second major surface opposite to the first major surface. The pressure sensitive adhesive is on at least part of the outer circumferential portion of the first major surface of the support layer, forming an adhesive coated area of the support layer.
