Segmented Compression Dressing With Bridge Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current reduced-pressure therapy systems for treating tissue sites, such as wounds, face challenges in efficiently managing fluid and pressure distribution, leading to suboptimal healing times and increased risk of infection due to fluid accumulation and uneven pressure application.
Innovation Solution
A bridge assembly with a storage bridge that includes a bridge envelope, absorbent, and sealing member, which defines an internal volume and passageway for fluid communication, coupled with a dressing and conduit interface, allows for efficient fluid management and pressure distribution, enhancing tissue healing by facilitating the migration of epithelial and subcutaneous tissues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If compression is applied to the dressing to reduce swelling and improve venous return, then therapeutic effect is improved, but the dressing may become dislodged or cause discomfort to the patient
Solution Approach 1:
The dressing is divided into multiple segments including a distal end portion, a proximal end portion, and intermediate portions with bridges. These segments can move independently relative to each other, allowing the dressing to accommodate swelling and body movements without becoming dislodged, while still maintaining compression therapy effectiveness.
Solution Approach 2:
The dressing incorporates dynamic elements such as bridges that can deform and move with body movements and swelling. The intermediate portions are configured to move relative to each other, creating a dynamic system that adapts to changing conditions while maintaining therapeutic compression.
2Stability of the object's composition
If the dressing is made rigid to maintain structural integrity and compression, then compression stability is improved, but comfort and adaptability to body movements deteriorate
Solution Approach 1:
The dressing is segmented into multiple portions connected by bridges, allowing each segment to maintain structural integrity for stable compression while the connections between segments provide flexibility for body movements.
Solution Approach 2:
The intermediate portions and bridges are designed as flexible elements that can deform and move with body contours and movements, while the overall dressing structure maintains sufficient rigidity to provide stable compression therapy.
3Object-affected harmful factors
If the dressing is made loose to prevent dislodgement and improve comfort, then patient comfort is improved, but compression effectiveness deteriorates
Solution Approach 1:
The dynamic configuration of intermediate portions that can move relative to each other allows the dressing to remain comfortable during body movements while automatically maintaining appropriate compression levels through the elastic properties of the material.
4Stability of the object's composition
If bridges are added to connect intermediate portions, then structural stability is improved, but device complexity increases
Solution Approach 1:
The dressing is segmented into manageable portions connected by simple bridge structures. This segmentation provides structural stability while keeping each individual component relatively simple, balancing overall structural integrity with manufacturing feasibility.
