Rigid Winged Wound Dressing for Local Bleeding Pressure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wound closure methods face challenges in applying consistent pressure to wounds, leading to discomfort, inadequate bleeding control, and increased risk of wound reopening, especially in non-extremity locations, and require manual adjustment by caregivers with experience.
Innovation Solution
A wound closure treatment system featuring a rigid or hard dressing member with upwardly extending wings that can be positioned to apply pressure directly to the wound site, providing consistent pressure through adjustable wing deformation, and later flipped for protection during healing, using a base portion and wings to secure the dressing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an elastic wrap is applied around an entire extremity to stop bleeding, then bleeding control is improved, but discomfort and circulation restriction occur
Solution Approach 1:
The dressing member is designed to apply pressure locally at the wound site rather than distributing pressure around the entire extremity. The base portion makes direct contact with the wound area to concentrate pressure where needed, while the wings extend outward to distribute the force application points, enabling localized hemorrhage control without restricting circulation to healthy tissue.
2Object-affected harmful factors
If adhesive tape is applied over gauze to wounds on head or torso, then the wound is protected, but sufficient pressure cannot be applied to stop bleeding
Solution Approach 1:
The wings are designed to be deformable under compression, allowing the caregiver to apply force dynamically during application. When the wings are compressed together, they transmit force to the base portion at the wound site, enabling the caregiver to apply adequate pressure to stop bleeding while maintaining wound protection through the rigid base structure.
3Ease of operation
If the wrap tightness is approximated by pressing on finger tips to gauge color return, then the method is simple to perform, but the pressure application is inconsistent and time-consuming
Solution Approach 1:
The dressing member is designed to be self-adjusting through its deformable wings. When the caregiver applies compression force to the wings, the structure automatically transmits and distributes this force to the wound site through the base portion. The design eliminates the need for complex gauging procedures by providing intuitive mechanical feedback through the deformable wings, allowing consistent pressure application based on simple compression of the wing structure.
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 controls bleeding and protects the wound site from reopening by ensuring consistent pressure application and minimizing discomfort, allowing for automatic pressure application and reduced manual intervention, while also offering protection during the healing process.
Implementation Method 1
one or more wings extending upwardly from the base portion... the wings are bendable relative to the base portion to a second angle to cause the base portion to apply pressure to the wound

AI summary
A wound closure treatment system includes a dressing member having an at least partially hard or rigid body, the body having a base portion and one or more wings extending upwardly from the base portion. The base portion has a top surface and a bottom surface. The dressing member is positionable atop a wound to be closed in a pressure application configuration where the bottom surface is adapted to apply pressure to the wound to help stop bleeding of the wound. The dressing member is also positionable atop the wound to be closed in a protection configuration where the top surface faces the wound in a manner where the dressing member protects the wound during healing. In one version, the wings are bendable relative to the base portion to cause the base portion to apply pressure to the wound. A method of using the wound closure treatment system is also disclosed.
