Adjustable Wound Covering With Tear Paths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current reduced-pressure wound therapy systems require cutting tools for sizing the adjustable coverings, which can be cumbersome and inefficient for healthcare providers.
Innovation Solution
The development of an adjustable covering with non-leaking tear paths and tear starters that allow for manual tearing without the need for cutting tools, enabling healthcare providers to size the covering to fit a tissue site without compromising the fluid seal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If cutting tools are used to size the adjustable covering, then the covering can be precisely sized to fit the tissue site, but the procedure becomes cumbersome and inefficient
Solution Approach 1:
The covering is divided into multiple segments along tear paths, allowing it to be manually torn into different sizes. The tear paths create predetermined separation lines that enable the covering to be divided into smaller sections without requiring cutting tools, thus maintaining sizing precision while improving operational simplicity.
Solution Approach 2:
Tear starters are pre-formed at specific locations along the tear paths to facilitate easy initiation of tearing. These pre-prepared features allow healthcare providers to quickly size the covering by simply pulling at the tear starters, eliminating the need for cutting tools and reducing the time and complexity of the sizing process.
2Adaptability or versatility
If the covering is made adjustable to fit different tissue sites, then versatility is improved, but the risk of compromising the fluid seal increases
Solution Approach 1:
The covering has different properties in different regions: the tear paths are designed to be easily torn, while the sealing portions are designed to maintain fluid integrity. The tear paths are positioned away from critical sealing areas, allowing the covering to be sized adaptively while preserving the reliability of the fluid seal at the tissue interface.
Solution Approach 2:
The tear paths act as intermediaries that allow size adjustment without compromising the sealing function. By providing dedicated tearing zones separated from the sealing zones, the design enables independent optimization of both adaptability and seal integrity - the tear paths facilitate size adjustment while the sealing portions maintain fluid barrier properties.

AI summary
Adjustable covers, systems, and methods are presented that include an adjustable cover that may be adjusted to an appropriate size by hand without requiring cutting tools and without substantial leaks. In one instance, the adjustable covering includes a drape member with a plurality of non-leaking tear paths. Each non-leaking tear path includes a weakened path of the drape member that may be torn. The adjustable covering may further include a first plurality of tear starters formed on a first initiation edge of the drape member. Each tear starter of the first plurality of tear starters is aligned with one of the plurality of tear paths. Each of the first plurality of tear starters is adapted to facilitate the initiation of a tear along a tear path. The grains of the drape member, a backing layer, and support layer may also be in the same direction. Other adjustable covers, systems, and methods are presented.
