Transparent Cutting Aid for Wound Dressing Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing negative pressure wound therapy devices face challenges in precisely adapting wound dressings to individual wound shapes and sizes, leading to issues like cavity formation or irritation of wound edges, and require complex and time-consuming adaptation processes that can compromise sterility.
Innovation Solution
A device featuring a liquid-permeable wound dressing with a transparent cutting aid that allows for precise cutting to match the wound's outline, using a self-adhesive transparent film for easy application and cutting, along with an airtight covering material for maintaining negative pressure, simplifies the adaptation process and ensures a tailored fit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If wound dressings are manually adapted to individual wound shapes and sizes, then the fit precision is improved, but the time required for application and sterility maintenance deteriorates
Solution Approach 1:
The patent applies preliminary action by providing wound dressings that are pre-cut to standard sizes and shapes before use. The transparent cutting aid with self-adhesive coating allows the dressing to be precisely adapted to the individual wound shape during application. This combines pre-preparation benefits with on-site customization, reducing both application time and maintaining sterility while achieving precise fit.
2Area of stationary object
If wound dressings are made larger to cover the wound area, then the coverage is improved, but the irritation of wound edges deteriorates
Solution Approach 1:
The patent applies local quality by enabling precise localization of the wound dressing to match the exact contours of the individual wound. The transparent cutting aid with self-adhesive coating allows the dressing to be cut to the precise shape and size of the wound, ensuring full coverage of the wound area while preventing overlap onto healthy surrounding skin, thereby eliminating edge irritation.
3Manufacturing precision
If wound dressings are made smaller to fit within the wound, then the precision of fit is improved, but the cavity formation deteriorates
Solution Approach 1:
The patent applies local quality by enabling precise adaptation of the wound dressing to the exact three-dimensional shape and size of the individual wound. The transparent cutting aid with self-adhesive coating allows the dressing to be cut to match the wound contours perfectly, ensuring the dressing fills the wound space completely without creating cavities or air pockets, while maintaining precise fit.
4Adaptability or versatility
If multiple types of wound dressings are kept available for different wound shapes, then the adaptability is improved, but the device complexity deteriorates
Solution Approach 1:
The patent applies universality by providing a single transparent cutting aid with self-adhesive coating that can be used with wound dressings of various sizes and shapes. This cutting aid enables one dressing type to be adapted to multiple different wound configurations, eliminating the need to maintain multiple specialized dressing types for different wound shapes while maintaining full adaptability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables quick, precise, and sterile adaptation of wound dressings, reducing the risk of cavities and edge irritation, improving comfort and effectiveness of negative pressure treatment while minimizing the number of dressing types needed.
Implementation Method 1
the transparent film has a self-adhesive coating at least on the second side opposite the first side, so that the cutting aid can be adhesively applied to the side of the wound dressing that is facing away from the wound
Implementation Method 2
an air-impermeable covering material for the airtight sealing of the wound and the area around the wound
Implementation Method 3
a means for functionally connecting the wound space to a negative pressure source located outside of the covering material, so that a negative pressure can be produced in the wound space and liquids can be drawn out of the wound space
