Multi-layered Dressing for Percutaneous Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dressings for percutaneous tubes and surgical sites are cumbersome, time-consuming to apply, and require multiple layers, making them inefficient and difficult for patients to manage, especially when needing to monitor the site for infection or healing.
Innovation Solution
A single, multi-layered dressing with concentric layers that combine therapeutic functions such as antimicrobial, hemostatic, and absorbent properties, covered by a transparent and impermeable outer layer, allowing for easy viewing and secure attachment to the skin and percutaneous device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple individual layers of dressing material are applied manually layer by layer, then the dressing provides comprehensive coverage and therapeutic functions, but the dressing becomes bulky, time-consuming to apply, and difficult for patients to manage
Solution Approach 1:
The patent combines multiple individual dressing layers into a single integrated multi-layered dressing structure. The layers are pre-assembled with therapeutic materials (antimicrobial, hemostatic, absorbent) integrated into concentric rings, eliminating the need for manual layer-by-layer application while maintaining comprehensive coverage and therapeutic functions.
Solution Approach 2:
The dressing is divided into distinct functional layers with specific therapeutic properties (antimicrobial, hemostatic, absorbent) arranged in concentric rings. Each layer performs a specific function, allowing the complex dressing to be broken down into manageable functional components that are pre-assembled into a single unit.
2Reliability
If the dressing is made of opaque material to provide coverage, then the dressing protects the surgical site, but the dressing cannot be transparent for monitoring the area without complete removal
Solution Approach 1:
The outer layer of the dressing is made transparent or translucent specifically at the area covering the surgical site, while maintaining protective coverage. This allows visual monitoring of the surgical site through the dressing without compromising protection, enabling patients and medical staff to detect signs of infection or complications without complete removal.
3Ease of operation
If the outer layer is made permeable to allow breathing, then the dressing is comfortable for the patient, but the dressing cannot prevent leakage of body secretions or fluids and block microbial entry
Solution Approach 1:
The outer layer is constructed from composite materials that combine impermeability to fluids and microbes with breathability properties. This allows the dressing to prevent leakage of body secretions and block microbial entry while still allowing water vapor transmission for patient comfort during extended wear.
4Reliability
If adhesive tape strips are used to attach each layer, then the dressing can be secured to the skin, but the dressing becomes awkward and time-consuming to apply
Solution Approach 1:
The dressing incorporates adhesive elements integrated into the single multi-layered structure, eliminating the need for separate adhesive tape strips for each layer. The concentric rings are pre-attached with adhesive, allowing the entire dressing to be applied as one unit, significantly reducing application time and simplifying the process for patients.

AI summary
A dressing for use with percutaneous tubes/drains/pins and tracheostomies that is designed to be impermeable to aid in the prevention of leakage of body secretions or fluids and to help prevent microbes from entering the body around the percutaneous device from the outside of the dressing. The dressing includes three layers or more including a layer having antimicrobial, bacteriocidal, or hemostatic agents, a cushioned absorbent layer covered by an outer see through impermeable adhesive layer.
