Medical Patch Support Liner Segmentation for Adhesion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medical patches face challenges in maintaining structural integrity and proper placement on the skin due to their thin, flexible adhesive films, which affects communication with in-vivo devices, and existing designs may cause discomfort and improper adhesion during application.
Innovation Solution
A medical patch design featuring a thin, flexible adhesive film with a support liner arrangement providing structural integrity, including multiple support liner pieces that reduce tugging forces and facilitate easy application, along with a communication layer and spacing layer to ensure effective signal transmission and adhesion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the adhesive film is made thin and flexible to conform to patient's skin and movements, then patient comfort is improved, but structural integrity deteriorates making it nearly impossible to properly place and adhere the film
Solution Approach 1:
The support liner is divided into multiple pieces (first support liner piece, second support liner piece, third support liner piece) that can be sequentially removed during application. This segmentation allows the adhesive film to maintain structural integrity when supported by the liner pieces during placement, while remaining thin and flexible for patient comfort during wear.
Solution Approach 2:
The support liner pieces are pre-attached to the adhesive film before application to the patient. This preliminary support structure provides the necessary structural integrity during the placement process, allowing the thin adhesive film to be properly positioned without compromising patient comfort once applied.
2Ease of operation
If multiple support liner pieces are used to provide structural integrity during application, then ease of application is improved, but device complexity increases
Solution Approach 1:
The support liner is segmented into multiple removable pieces that can be sequentially taken off during application. This segmentation simplifies the application process by allowing controlled removal of support structures, while the pieces are designed to be integrated components that do not significantly increase overall device complexity.
