Adjustable Compression Sleeve for Amputated Limbs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compression therapy devices for amputated limbs are cumbersome to customize and cannot be easily adjusted for varying lengths, limiting their use under different conditions such as standing or walking.
Innovation Solution
An adjustable inflatable compression sleeve with a customizable pocket that can be inflated or deflated to fit different amputation lengths, combined with a harness for secure attachment, allowing for personalized and versatile compression therapy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a custom compression device is made for each amputation, then the compression therapy effectiveness is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The compression device is designed with an adjustable compression pocket that can be modified to fit various amputation lengths and positions, allowing a single device design to serve multiple patients with different amputation characteristics, thereby maintaining therapy effectiveness while reducing customization complexity
2Ease of manufacture
If a fixed-length compression device is used, then the manufacturing process is simplified, but the adaptability to different amputation lengths is reduced
Solution Approach 1:
The compression pocket is designed with adjustable features including extendable sections and repositionable closures that allow the device to be dynamically adapted to different amputation lengths, maintaining manufacturing simplicity while achieving versatility
3Adaptability or versatility
If the compression device is made adjustable for various amputation lengths, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The compression pocket is divided into multiple sections that can be independently adjusted or reconfigured, allowing the device to adapt to different amputation lengths through simple modular adjustments rather than complex mechanisms
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 device provides effective and adjustable compression therapy for a wide range of amputated limb lengths, enabling use during various activities like standing or walking, enhancing blood circulation, reducing edema, and promoting wound healing.
Implementation Method 1
an inflatable bladder, configured to be surroundingly engageable around the amputated limb (in particular on the circumference of the limb)
Implementation Method 2
an associated adjustable compression pocket which is configured to adjust in height/length and to engage the face of the stump, to provide compression therapy thereto
