Adhesive Wound Closure Device for Negative Pressure Therapy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wound closure devices often cause tissue breakdown due to the use of sharp hooks or barbs and are not compatible with reduced pressure therapy, and they may not be effective for larger wounds lacking sufficient dermal, epidermal, and subcutaneous tissue coverage.
Innovation Solution
A wound treatment device comprising a first body with adjustable elongated sections that can be mechanically coupled to tissue around a wound using an adhesive, allowing for controlled mechanical forces to approximate wound margins while being compatible with reduced pressure therapy systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If sharp hooks or barbs are used for wound closure, then mechanical attachment to tissue is achieved, but tissue breakdown occurs
Solution Approach 1:
The patent replaces the mechanical hook or barb system with an adhesive bonding system. The adhesive is applied to the skin surface and bonds the closure device to the tissue without penetrating or mechanically piercing the tissue, thereby eliminating tissue damage while maintaining attachment strength.
Solution Approach 2:
The adhesive acts as an intermediary substance between the closure device and the tissue. Instead of direct mechanical contact that causes damage, the adhesive mediates the attachment process, bonding the device to the skin surface without causing tissue breakdown.
2Shape
If traditional wound closure devices are used, then wound approximation is achieved, but compatibility with reduced pressure therapy is lost
Solution Approach 1:
The closure device is designed with universal compatibility, allowing it to function both for wound approximation and in conjunction with reduced pressure therapy. The device can be attached to the skin surface with adhesive and then covered by the reduced pressure therapy drape, enabling simultaneous use of both treatments without interference.
3Area of stationary object
If traditional closure devices are used for larger wounds, then wound closure is attempted, but effectiveness is reduced due to insufficient tissue coverage
Solution Approach 1:
The closure device can be segmented into multiple sections or components that can be distributed across larger wound areas. This allows the device to effectively approximate wound margins even when the wound is large and surrounding tissue coverage is limited, by distributing the closure function across multiple attachment points.
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 device effectively approximates wound margins without tissue damage and can be used with reduced pressure therapy, facilitating wound closure without the need for skin grafts or reconstructive procedures, suitable for various wound shapes and sizes.
Implementation Method 1
an adhesive for mechanically coupling two or more connectors, each attached to one of the two or more elongated sections, to tissue surrounding a wound
Implementation Method 2
at least one first opening configured for attachment to a reduced pressure source
