Expandable Strap Compression Sleeve with Visual Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current compression devices for treating venous and lymphatic disorders, such as compression stockings and bandages, often lack ease of use and require trained professionals for application, and fail to provide consistent compression, especially as limb volume changes during treatment.
Innovation Solution
A compression device featuring a sleeve with expandable straps or gussets and mechanical fastening tabs that provide visual feedback on proper fit and tension, allowing for easy application and adjustment by non-trained personnel, ensuring uniform compression and indicating when re-tightening is needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If compression bandages are used to provide effective compression therapy, then compression efficacy is improved, but application difficulty increases and requires trained professionals
Solution Approach 1:
The compression device is divided into a sleeve portion and a fastening tab portion that can be separately handled. The fastening tab is detachably connected to the sleeve, allowing the user to first position the sleeve on the limb and then separately secure it with the tab, simplifying the application process while maintaining compression effectiveness
Solution Approach 2:
The fastening tab acts as an intermediary component between the sleeve and the fastening mechanism (rings/eyelets). This intermediary element transfers the fastening force to the sleeve, enabling secure compression without requiring the user to directly manipulate the sleeve material, thus reducing application difficulty
2Reliability
If compression bandages are used to maintain compression pressure, then compression consistency is improved, but device complexity increases due to frequent reapplication
Solution Approach 1:
The expandable portion of the strap allows the device to dynamically adapt to changes in limb volume. As the limb swells or shrinks during treatment, the expandable strap adjusts accordingly, maintaining consistent compression pressure without requiring manual reapplication or adjustment by healthcare professionals
Solution Approach 2:
The expandable portion automatically adjusts to limb volume changes without external intervention. The elastic or expandable material self-regulates the compression force based on the current limb dimensions, eliminating the need for frequent professional reapplication and reducing device complexity
3Ease of operation
If compression stockings are used to provide ease of use, then ease of operation is improved, but compression efficacy deteriorates
Solution Approach 1:
The device separates the ease-of-use sleeve from the secure fastening mechanism. The sleeve can be easily positioned on the limb like a stocking, while the detachable fastening tab provides the secure, effective compression of a bandage, combining the advantages of both approaches
Solution Approach 2:
The ring or eyelet fastening points are positioned at specific locations on the sleeve to optimize the distribution of compression force around the limb's curved surface, ensuring effective compression while maintaining ease of application
4Ease of operation
If expandable straps with visual indicators are added to indicate proper fit, then ease of operation is improved through visual feedback, but device complexity increases
Solution Approach 1:
The expandable portion incorporates visual indicators such as color changes or visible expansion patterns that change state when proper tension is achieved. This allows users to immediately verify correct application without requiring training or complex measurement tools, while the visual indicator itself is integrated into the strap structure
Solution Approach 2:
The visual indicator system replaces complex mechanical measurement or adjustment mechanisms. Instead of requiring users to calculate or measure compression forces, the visual feedback system provides intuitive, immediate information about proper fit, simplifying the user interface while maintaining compression effectiveness

Implementation Method 1
at least a portion of said strap being expandable in at least the transverse direction, wherein said expandable portion comprises a material having elasticity in at least the transverse direction of the sleeve and is configured and arranged, such that when the expandable portion is in its non-expanded state there is exteriorly a loop of material rising outwardly and when, in use under the provision of tension in the transverse direction of the sleeve, the expandable portion expands in the transverse direction and the loop flattens

AI summary
The disclosed compression device comprises a sleeve with straps for applying compression to a limb. The sleeve is provided with a plurality of rings in series releasably or fixedly attached by a strap. At least a portion of said strap is expandable. When the expandable portion is in its non- expanded state there is exteriorly a loop of material rising outwardly and when, in use under the provision of tension in the transverse direction of the sleeve, the expandable portion expands in the transverse direction and the loop flattens. The device further comprises a plurality of strip- shaped mechanical fastening tabs, wherein a single tab is provided for each ring. The tabs and rings are configured and arranged such that, in use, the tabs are passed through the rings, turned back on themselves such that the first lateral side edge of the sleeve is drawn towards the rings and then fastened so that the sleeve is tightened and restrained about the limb of the user.
