Foldable Adhesive Dressing With Hinged Drug Reservoir
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current transdermal and topical drug delivery methods face limitations due to the barrier properties of the skin, and existing devices are often complex or limited in their ability to effectively deliver active ingredients, either by integrating multiple functions or requiring separate steps for skin treatment and drug delivery.
Innovation Solution
An adhesive composite dressing comprising an anchor member, a target member, and a folding member with a drug reservoir, where the folding member is attached to the anchor portion through a hinge, ensuring accurate alignment with treated skin areas, and can be used in conjunction with skin treatment devices like microneedle arrays or RF ablation devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single integrated device performs both skin treatment and drug delivery, then the administration process is simplified, but the device complexity increases and the amount of drug delivery is limited
Solution Approach 1:
The system is divided into two separate components: a skin treatment device and a drug reservoir dressing. The skin treatment device is used first to create pores or increase permeability, then the drug reservoir dressing is applied separately to deliver the active ingredient. This segmentation allows each device to be optimized for its specific function while maintaining overall simplicity in the administration process.
2Ease of operation
If a single integrated device performs both skin treatment and drug delivery, then the administration process is simplified, but the amount of drug delivery is limited
Solution Approach 1:
By separating the skin treatment function from the drug delivery function, the system allows for optimized performance in each area. The drug reservoir can be designed with sufficient capacity to deliver the required amount of active ingredient without being constrained by the limitations of integrated device designs.
3Device complexity
If skin treatment and drug delivery are performed in separate steps, then the device design is simplified and flexibility is improved, but an additional user step is required
Solution Approach 1:
The skin treatment is performed as a preliminary action before drug delivery. The pores or increased permeability are created in advance using the skin treatment device, and then the drug reservoir dressing is applied to take advantage of the pre-prepared skin surface. This sequencing allows for simplified device design while maintaining ease of operation through a logical progression of steps.
4Ease of operation
If the drug reservoir is placed on treated skin without alignment features, then the application is simpler, but the alignment precision with the treated area deteriorates
Solution Approach 1:
The dressing incorporates visual alignment features such as colored markers, patterns, or contrasting elements that correspond to the treated area. These visual cues enable the user to accurately position and align the drug reservoir with the treated skin area, ensuring precise delivery without complicating the application process.

Function Achieved in This Case
The adhesive composite dressing ensures precise delivery of active ingredients to treated skin areas, enhancing drug permeability and flexibility in drug delivery, while simplifying the administration process and device design.
Implementation Method 1
the folding member is attached to the anchor portion through a hinge defined by a line of attachment that is not contiguous with an edge of the anchor member
