Compression Garment Baseline Pressure Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vascular compression garments tend to loosen or misalign during ambulation, leading to ineffective compression therapy and discomfort due to the inability to maintain the inflatable bladders in position over the target compression zones.
Innovation Solution
A compression garment apparatus with inflatable therapeutic bladders and a pressurizer system that includes sensors to adjust baseline pressure based on physical characteristics such as orientation, motion, and acceleration, ensuring the bladders remain aligned with the target zones and providing intermittent compression therapy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the compression garment is made loose-fitting for comfort during ambulation, then the wearer's mobility and comfort are improved, but the inflatable bladders cannot maintain position over the target compression zones, reducing therapy effectiveness
Solution Approach 1:
The system dynamically adjusts baseline pressure in response to detected motion or orientation changes. The controller receives signals from motion sensors and modifies the baseline pressure accordingly to maintain bladder positioning during ambulation, transforming a static positioning problem into a dynamic control solution.
Solution Approach 2:
The system incorporates motion sensors that detect wearer movement and feed this information back to the controller. The controller then adjusts baseline pressure based on the sensed motion, creating a closed-loop feedback system that maintains therapeutic effectiveness during ambulation.
2Reliability
If the compression garment is made tight-fitting to maintain bladder position, then the bladders remain aligned with target zones, but the garment loosens or slides down during ambulation, causing misalignment and discomfort
Solution Approach 1:
Rather than using a static tight fit, the system employs dynamic baseline pressure adjustment. The baseline pressure is modulated in real-time based on motion detection, providing just enough force to maintain positioning during movement while avoiding the discomfort of constant tightness.
Solution Approach 2:
The system changes the pressure parameter dynamically during ambulation. By adjusting baseline pressure in response to motion, the system adapts the mechanical properties of the garment to maintain positioning without requiring a permanently tight fit.
3Reliability
If baseline pressure is increased to prevent garment slippage during movement, then the bladders maintain position, but the compression therapy becomes excessively tight and uncomfortable when stationary
Solution Approach 1:
The system applies baseline pressure periodically or intermittently based on motion detection. When motion is detected, baseline pressure is applied to maintain positioning; when stationary, the pressure is reduced or released, avoiding continuous discomfort while maintaining positioning only when needed.
Solution Approach 2:
The baseline pressure is made dynamic rather than static. The controller adjusts pressure levels in real-time based on motion state, applying higher pressure during movement to prevent slippage and lower pressure when stationary to ensure comfort.
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 system effectively maintains the bladders in position, enhancing the effectiveness and comfort of compression therapy by adjusting baseline pressure in response to the wearer's movements and orientations, preventing slippage and maintaining therapeutic compression.
Implementation Method 1
The pressurizer includes a sensor for sensing and generating signals representative of at least one physical characteristic selected from a group of characteristics consisting of an orientation of the body part, a motion of the body part, an acceleration of the body part
Implementation Method 2
The pressurizer operatively connectable to the therapeutic bladder for selectively pressurizing the therapeutic bladder by increasing gas pressure within the therapeutic bladder to provide therapeutic compression therapy
Implementation Method 3
The controller maintains a baseline pressure in the therapeutic bladder to maintain the therapeutic bladder in position with respect to the target compression zone

AI summary
A compression garment apparatus including a compression garment and a pressurizer. The pressurizer intermittently pressurizes a therapeutic bladder on the compression garment and maintains a baseline pressure in the therapeutic bladder to maintain the therapeutic bladder in position with respect to a target compression zone on a body part on which the garment is worn. The baseline pressure is adjusted in response to sensed physical characteristics.
