Elastic Wound Wrap Structure for Joint-Safe Bandage Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adhesive bandages fail to adequately protect wounds from external contaminants, particularly at joints, due to buckling and loosening of the adhesive, and often provide insufficient gauze coverage.
Innovation Solution
A wound/bandage protection system featuring a super-stretch tube made of elastic non-woven material with a strip along its length, and a wrap with catch and final fasteners, allowing secure application and maximizing gauze coverage while accommodating joint movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive bandages use a thin strip of adhesive around the gauze pad to adhere to the skin, then the wound can be sealed, but the adhesive buckles or comes loose particularly at joints
Solution Approach 1:
The bandage incorporates an elastic member that can dynamically stretch and retract, allowing the adhesive to maintain contact with the skin during joint movement. The elastic member transforms the static adhesive application into a dynamic system that adapts to limb movement, preventing buckling and loosening at joints.
Solution Approach 2:
The invention changes the physical parameters of the bandage by introducing an elastic member with specific stretch properties. This allows the adhesive strip to maintain optimal tension and contact pressure on the skin even when the joint moves, preventing the adhesive from buckling or coming loose while maintaining reliable wound sealing.
2Quantity of substance
If the gauze is extended to the edge of the adhesive to maximize wound coverage, then more gauze is available, but the adhesive seal becomes weaker
Solution Approach 1:
The bandage is segmented into distinct functional zones: a central gauze area for wound coverage and peripheral adhesive areas for sealing. The elastic member connects these zones, allowing the gauze to extend maximally while the elastic component maintains the adhesive seal by providing tensile strength and preventing the adhesive from pulling away during movement.
3Adaptability or versatility
If the bandage is made to conform to joint bending, then it can be applied to joints, but the adhesive and gauze buckle significantly
Solution Approach 1:
The elastic member provides dynamic adaptability to joint movement, allowing the bandage to conform to bending without buckling. When the joint bends, the elastic member stretches accordingly, maintaining tension throughout the bandage and preventing the gauze and adhesive from buckling, while still allowing application to joint areas.
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 system effectively prevents buckling and loosening of the adhesive, ensuring consistent wound protection and maximizing gauze coverage, even at joints, thereby enhancing durability and comfort.
Implementation Method 1
The super-stretch tube is preferably made of a super-stretchable elastic non-woven material
