Compression Garment System for Lymphedema Treatment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current compression garments for lymphedema treatment lack effective mechanisms to dynamically apply pressure sequences to move lymph from the head and neck to the torso, limiting their therapeutic efficacy.
Innovation Solution
A compression garment system comprising a head and torso garment with controllable pressure regions, a controller, and a pump that applies sequential and non-sequential pressure sequences to prepare the body for lymph drainage, moving lymph from the head to the neck and then to the torso, utilizing inflatable chambers and actuatable elements for dynamic pressure application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If compression garments use static pressure application, then the garment structure is simple, but the therapeutic efficacy is limited due to inability to dynamically move lymph
Solution Approach 1:
The compression garment is divided into multiple independently controllable pressure zones (e.g., first, second, and third pressure zones along the limb) that can be inflated and deflated in specific sequences. This segmentation allows dynamic pressure application to effectively move lymph through different regions, enhancing therapeutic efficacy while maintaining a modular structure that can be controlled by a pump system.
Solution Approach 2:
The garment transitions from static pressure application to dynamic pressure application through a pump system that can inflate and deflate different pressure zones in controlled sequences. The dynamic pressure changes create pressure gradients that actively move lymph from distal to proximal regions, significantly improving therapeutic effectiveness despite increased system complexity.
2Reliability
If compression garments apply uniform pressure, then the garment design is simple, but the ability to prepare body for lymph drainage is insufficient
Solution Approach 1:
Different pressure zones within the garment are designed to apply different pressure levels and inflation sequences to specific regions. For example, distal zones may be inflated first to prepare those areas for drainage, followed by proximal zones. This localized pressure control optimizes lymph movement through each region while maintaining overall system coordination.
Solution Approach 2:
The pump system inflates pressure zones in a predetermined sequence before actual lymph drainage begins. Distal pressure zones are inflated first to prepare those regions by compressing tissues and positioning lymph for subsequent drainage when proximal zones are inflated. This preliminary action enhances the overall drainage effectiveness.
3Productivity
If compression garments lack sequential pressure application, then the operation is simple, but the productivity of lymph drainage is reduced
Solution Approach 1:
The pump system implements periodic inflation and deflation cycles of different pressure zones in a specific sequence. This periodic action creates rhythmic pressure changes that actively propel lymph through the limb, significantly increasing drainage rate compared to static compression. The controller coordinates these periodic cycles across multiple zones to maintain continuous lymph flow.

Function Achieved in This Case
The system enhances lymph drainage by applying controlled pressure sequences, effectively moving lymph from the head and neck to the torso, thereby improving treatment outcomes for lymphedema.
Implementation Method 1
A compression garment system includes a pump and a controller. The compression garment includes a head and torso garment including a plurality of head pressure applying regions controllable to apply pressure to a plurality of portions of a head of a body and a plurality of torso pressure applying regions controllable to apply pressure to a plurality of portions of a torso of the body.
Implementation Method 2
When in the preparation phase, the controller is configured to apply pressure to the plurality of portions of the torso and the plurality of portions of the head using the plurality of torso pressure applying regions and the plurality of head pressure applying regions to prepare the torso of the body for lymph to be drained from the head and neck of the body.

AI summary
Compression garments and methods may include a head garment configured to be positioned around both sides of a head of a body from a posterior of the head to an anterior of the head and a torso garment. Such garment portions may include one or more controllable pressure applying regions to move lymph from the head downward to the torso.
