Wound Barrier Pad with Adhesive Ring for Shear Force Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Patients with mobility issues are at high risk of developing pressure ulcers due to prolonged pressure and shear forces on specific body areas, and existing treatments are inadequate in preventing these forces, leading to ineffective prevention and treatment of pressure ulcers.
Innovation Solution
A wound barrier pad with a housing and padding that absorbs and distributes pressure and shear forces, which can be integrated into a garment or used with an adhesive ring to maintain its position over the wound, reducing friction and pressure on sensitive areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional barrier dressings and repositioning methods are used, then pressure ulcer prevention is attempted, but they fail to effectively protect wounds from pressure and shear forces in difficult-to-reach areas
Solution Approach 1:
The patent introduces a specialized barrier device as an intermediary between the patient's body and the harmful pressure/shear forces. This device includes a low-friction liner layer that directly contacts the wound, absorbing and redistributing forces before they reach the vulnerable tissue, thereby effectively protecting the wound in areas difficult to reach with conventional dressings
Solution Approach 2:
The barrier device employs a composite structure with multiple functional layers: a low-friction liner layer for force distribution, an adhesive layer for secure positioning, and a breathable outer layer. This composite design combines materials with different properties to simultaneously achieve force absorption, stable attachment, and wound healing conditions
2Stress or pressure
If patients are repositioned frequently to prevent pressure ulcers, then pressure distribution is improved, but patient comfort decreases and nursing care complexity increases
Solution Approach 1:
The barrier device is applied in advance to high-risk areas before pressure ulcers develop. Once in place, it provides continuous protection during normal positioning activities, eliminating the need for frequent repositioning interventions while maintaining pressure distribution, thereby simplifying nursing care routines
3Stability of the object's composition
If adhesive dressings are used to secure barrier dressings, then positioning stability is improved, but skin irritation and discomfort increase
Solution Approach 1:
The adhesive is applied locally only at the periphery of the barrier device, away from the wound area. This localized application strategy provides sufficient positioning stability through edge anchoring while leaving the central wound-contact area free of adhesive, thereby preventing skin irritation and discomfort at the sensitive wound site
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 wound barrier pad effectively isolates wounds from pressure and shear forces, enhancing the prevention and treatment of pressure ulcers by maintaining even load distribution and reducing friction, thereby promoting healing and preventing further injury.
Implementation Method 1
The padding is a resilient padding, foam

AI summary
A wound barrier pad is provided having a housing with a housing opening. The housing has a truncated conical shape. A base plate with an opening is disposed in the housing, and the housing is filled with a fluid or padding. The wound barrier pad may also be embodied to have a cylindrical shape, a rectangular shape or other shape. The wound barrier pad may be incorporated into a garment. In another embodiment the wound barrier pad includes a ring and an adhesive such that the wound barrier pad may be directly adhered to the patient, thus eliminating the need for the garment. In another embodiment there is a wound barrier device having a pad assembly and an anti-sheer member. The anti-shear member reduces frictional forces on the skin of a patient. In another embodiment a wound barrier assembly is provided for applying a negative pressure to a wound.
