Auxiliary Adhesive Patch Structure for Stable CGM Skin Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional continuous glucose monitoring systems face issues with adhesive tape size requirements that lead to increased applicator size, manufacturing costs, and reduced adhesive force, which complicates use and design flexibility.
Innovation Solution
An auxiliary adhesive patch with an over patch and separable release paper, allowing for minimized adhesive tape size while enhancing adhesion and facilitating easy application by separating the release paper into multiple pieces for stable fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the adhesive tape size is minimized, then manufacturing cost and applicator size are reduced, but adhesive force is weakened
Solution Approach 1:
The patent combines the adhesive tape with an auxiliary adhesive patch to form a composite adhesive structure. The auxiliary patch is applied over the adhesive tape to provide additional adhesive force, thereby maintaining strong adhesion while keeping the original adhesive tape size minimized for cost-effective manufacturing and compact applicator design.
2Length of stationary object
If the adhesive tape size is minimized, then applicator size is reduced, but adhesive force is weakened
Solution Approach 1:
The adhesive tape is merged with an auxiliary adhesive patch to create a dual-layer adhesive system. This allows the applicator to remain compact with minimized adhesive tape size while the auxiliary patch contributes additional adhesive force to compensate for the reduced tape area.
3Device complexity
If the release paper is attached as a single piece, then protection is simple, but position stability during separation is poor
Solution Approach 1:
The release paper is segmented into multiple separate pieces, each corresponding to a specific adhesive region. This segmentation allows each piece to be independently removed without affecting the position stability of the remaining release paper pieces, thereby improving position stability during the separation process while maintaining relatively simple overall structure.
4Adaptability or versatility
If the adhesive tape size is minimized, then design flexibility is improved, but adhesive force is weakened
Solution Approach 1:
The minimized adhesive tape is merged with an auxiliary adhesive patch to create a composite adhesive system. This enables design flexibility with small adhesive tape size while the auxiliary patch provides the necessary adhesive force, allowing for more adaptable and versatile device designs.

AI summary
The present disclosure relates to an auxiliary adhesive patch of a body attachment unit for a continuous blood glucose monitoring device. The present invention provides an auxiliary adhesive patch of a body attachment unit for a continuous blood glucose monitoring device, which: includes a separate over-patch surrounding an adhesive tape of a body attachment unit and attached to a skin, so that the size of the adhesive tape of the body attachment unit can be kept to be minimum and, in this state, the body attachment unit can be additionally attached and fixed to the skin so as to strengthen the adhesive force thereof; and has a plurality of release sheets attached to an adhesive surface of the over-patch, wherein each of the release sheets is separately formed and has a protection area formed to include an adhesive area and a part of a pressurization area of the over-patch, so that, in the process of detaching the release sheets, the position of the over-patch can be stably held and the over-patch can thus be attached conveniently and rapidly.
