Integrated Negative-Pressure Wound Dressing Electronics for Exudate Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing negative pressure wound therapy systems face challenges with remote negative pressure sources that are cumbersome, difficult to position comfortably, and prone to wound exudate absorption, making it hard to incorporate electronic components effectively.
Innovation Solution
Incorporating a negative pressure source and electronic components into a wound dressing as an integral structure, with a flexible film enclosure and porous windows, allowing for fluid communication and protection against exudate entry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a remote negative pressure source is used, then the wound dressing can be simpler, but the system becomes cumbersome and difficult to position comfortably
Solution Approach 1:
The patent combines the negative pressure source with the wound dressing into an integrated unit. The pump is positioned within the dressing structure itself, eliminating the need for separate remote pumping equipment and tubing connections. This merging resolves the contradiction by maintaining dressing simplicity while improving positioning convenience through a self-contained design.
2Adaptability or versatility
If electronic components are incorporated into the wound dressing, then the system becomes more functional, but wound exudate may damage the electronics
Solution Approach 1:
The patent uses a flexible impermeable membrane to enclose the electronic components within the wound dressing. This membrane acts as a protective barrier that prevents wound exudate from reaching and damaging the electronics while allowing the dressing to maintain its flexibility and conformability to the wound site.
3Ease of operation
If the negative pressure source is integrated into the wound dressing, then positioning is easier, but the dressing structure becomes more complex
Solution Approach 1:
The patent nests the negative pressure source within the existing wound dressing structure. The pump is positioned in a recess or cavity formed by the dressing layers, with the impermeable membrane integrating into the dressing architecture. This nesting approach minimizes structural complexity while achieving integrated positioning.
4Reliability
If an impermeable cover is used to protect electronics, then electronics are protected from exudate, but fluid communication with the wound is blocked
Solution Approach 1:
The patent applies local quality by making the cover impermeable only in the regions where electronics are located, while maintaining permeability in other areas of the dressing that require fluid communication with the wound. This selective permeability allows the system to protect electronics while preserving wound exudate collection functionality.
