Saphenous Vein Compression Garment for Stable Thigh Pressure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current compression therapies for conditions like CVI, lymphedema, and DVT are cumbersome, require skilled application, slip down the leg, and fail to provide consistent, localized compression, especially on the thigh, posing risks and complications.
Innovation Solution
A saphenous vein compression system with a bolster wound dressing and compression garment, featuring adjustable bladders and stabilization means, allowing self-administration and consistent pressure application along the saphenous vein, including a pre-filled air bladder and elastic liner, to prevent slipping and enhance venous circulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If compression bandages are applied with constant tension to produce graduated compression, then venous circulation is improved, but the application technique is difficult and requires highly skilled caregivers
Solution Approach 1:
The compression system enables patients to self-apply compression garments without requiring skilled caregivers. The system includes instructional materials and design features that allow patients to properly position and adjust the compression garment themselves, eliminating the need for specialized application skills while maintaining therapeutic effectiveness.
Solution Approach 2:
The compression system transitions from static bandaging to dynamic compression through inflatable chambers that can be adjusted and re-inflated. The system includes a pump mechanism that allows patients to adjust compression levels dynamically, providing graduated compression without requiring skilled application techniques.
2Reliability
If compression stockings are used to decrease chronic swelling, then venous circulation is improved, but the stockings slip down the leg and fail to provide consistent compression
Solution Approach 1:
The compression system divides the leg into multiple compression zones using separate inflatable chambers for the thigh, calf, and foot areas. This segmentation allows independent adjustment of compression in each zone and prevents the garment from slipping as a unified structure, maintaining consistent compression throughout the leg.
Solution Approach 2:
The system includes pressure sensors that monitor compression levels in real-time and provide feedback to the pump mechanism. When compression drops below therapeutic thresholds or the garment shifts position, the system automatically adjusts inflation to restore proper compression levels, ensuring consistent therapeutic effect.
3Reliability
If manual inflatable air bladder devices are used for localized compression, then venous ulcer healing is improved, but the devices are not configured to apply localized compression to the thigh
Solution Approach 1:
The compression system is designed as a multi-functional device that can apply localized compression to multiple locations including the thigh, calf, and foot. The system includes multiple inflatable chambers that can be independently activated to treat different areas, making it universally applicable to various venous disease locations without requiring separate devices.
Solution Approach 2:
The system applies different compression levels and patterns to different locations along the leg based on specific therapeutic needs. Each inflatable chamber can be independently controlled to provide optimized compression for its specific location, whether for ulcer healing on the thigh or circulation improvement in the calf.
4Reliability
If compression bandaging is applied to treat lymphedema, then edema reduction is achieved, but the bandaging is time-consuming and effectiveness is limited by provider skill
Solution Approach 1:
The compression system allows patients to self-apply and adjust compression therapy without requiring time-consuming professional bandaging. Patients can quickly inflate or deflate chambers as needed, making the therapy accessible without scheduling appointments with skilled providers and eliminating the time investment required for manual bandaging application.
