Compression Device Axial Band Overlap Spine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compression devices for treating oedema and venous lymphatic disorders often fail to provide consistent therapeutic pressure due to difficulties in applying and maintaining the correct fit, leading to axial gaps and reduced effectiveness.
Innovation Solution
A compression device with a spine element featuring offset guide openings to guide band portions, ensuring axial overlap and preventing entanglement, facilitating easier application and maintaining consistent pressure around the limb.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If bands are made longer to provide compression around a larger portion of the limb circumference, then the compression coverage is improved, but the bands become more easily entangled and harder to position correctly
Solution Approach 1:
The spine element is pre-formed with guide openings positioned at specific locations and orientations before the bands are attached. This preliminary configuration of the spine element with properly spaced guide openings eliminates the entanglement problem that would otherwise occur with long bands, while still providing comprehensive compression coverage around the limb.
Solution Approach 2:
The guide openings in the spine element serve as intermediary structures that control the path and positioning of the bands. These guide openings act as mediators between the long bands and the limb, preventing band entanglement by directing bands through predetermined paths while maintaining the compression coverage benefits of long bands.
2Reliability
If bands are positioned to overlap axially for complete compression coverage, then the compression effectiveness is improved, but the difficulty of achieving proper positioning increases
Solution Approach 1:
The guide openings in the spine element are pre-positioned to ensure that when bands are threaded through them, the bands will automatically achieve the desired axial overlap. This preliminary configuration of the guide openings eliminates the difficulty of manually positioning bands to achieve consistent compression coverage.
Solution Approach 2:
The guide openings act as intermediary structures that control band positioning. By threading bands through these pre-positioned guide openings, the system automatically achieves the required axial overlap for consistent compression, without requiring manual adjustment or complex positioning procedures.
3Ease of operation
If compression devices use simple band structures for ease of application, then the ease of operation is improved, but the ability to maintain consistent therapeutic pressure deteriorates
Solution Approach 1:
The compression device is segmented into a spine element with multiple guide openings and multiple bands that can be independently adjusted. This segmentation allows each band to be positioned through its own guide opening, maintaining simple application procedures while ensuring consistent therapeutic pressure through controlled band positioning and overlap.
Solution Approach 2:
The guide openings in the spine element serve as intermediary structures that maintain consistent band positioning and tension. These guide openings ensure that bands are applied at the correct angles and positions, thereby maintaining consistent therapeutic pressure while keeping the application process simple and straightforward.

AI summary
Compression device (1) for application circumferentially around a patient's limb (10), comprising a) a first band portion (20a) and a second band portion (20b), both band portions (20) being arrangeable along at least a part of the circumference of the limb for creating radial pressure on the limb, b) a spine element (30), extending in axial direction (100) when the compression device is applied around the limb, and comprising a first and a second guide opening (40a, 40b) for guiding the first and the second band portions, respectively. The guide openings (40a, 40b) are arranged offset in axial direction with respect to each other such that, when the first band portion is arranged along at least a part of the circumference of the limb and guided through the first guide opening, and the second band portion is arranged along at least a part of the circumference of the limb, parallel to the first band portion, and guided through the second guide opening, the band portions overlap in an axial direction.
