Modular Pressure Chambers for Dynamic Pressure Injury Relief
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pressure-relief technologies fail to effectively manage the spatial relationship between the human body and support surfaces, leading to pressure injuries and complications, particularly in immobile individuals, due to inadequate control over pressure distribution and coordination across multiple surfaces.
Innovation Solution
A modular pressure-mitigation device with individually controllable chambers, controlled by a controller, that dynamically adjusts pressure distribution to alleviate pressure on specific anatomical regions by inflating or deflating chambers, allowing for intelligent and autonomous fluid circulation to prevent ischemia and promote blood flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional pressure-relief technologies are used, then pressure distribution is provided, but the spatial relationship between the human body and support surfaces cannot be controlled, leading to pressure injuries
Solution Approach 1:
The support surface is divided into multiple independently controllable chambers or zones. Each chamber can be individually inflated or deflated to create specific pressure patterns, allowing precise control over the spatial relationship between the support surface and the human body. This segmentation enables targeted pressure application to prevent injuries in specific anatomical regions.
Solution Approach 2:
The system dynamically adjusts the inflation/deflation state of individual chambers in real-time based on detected body position and pressure distribution. This dynamic control allows the support surface to adapt continuously to changing body contours and pressure points, maintaining optimal spatial relationships and preventing pressure injuries throughout the support period.
2Adaptability or versatility
If multiple surfaces that apply pressure to various parts of the human body are used, then pressure relief is provided, but coordination between multiple surfaces is insufficient
Solution Approach 1:
Multiple pressure application surfaces are merged into a single integrated system with centralized control. The controller coordinates all chambers across different surfaces, allowing them to operate independently or in unison as needed. This merging reduces the complexity of managing multiple separate devices while maintaining comprehensive pressure relief coverage across various anatomical regions.
Solution Approach 2:
The integrated control system provides universal functionality across all pressure application surfaces. A single controller manages the inflation/deflation of chambers throughout the entire support surface, enabling coordinated operation for different therapeutic goals such as pressure redistribution, body positioning, and injury prevention across multiple anatomical areas.
3Ease of operation
If individuals operate multiple devices that control multiple surfaces, then pressure distribution is achieved, but the outcome is still pressure injuries or related complications
Solution Approach 1:
The system incorporates sensors and controllers that automatically detect body position, pressure distribution, and chamber inflation/deflation states. The controller autonomously adjusts chamber states based on real-time feedback, eliminating the need for manual operation by the user. This self-service capability ensures consistent, error-free pressure distribution control that reliably prevents pressure injuries without requiring user intervention.
Solution Approach 2:
The system continuously monitors pressure distribution, chamber inflation states, and body position through integrated sensors, feeding this information back to the controller. Based on this feedback, the controller dynamically adjusts the inflation/deflation of individual chambers to maintain optimal pressure patterns, ensuring reliable pressure injury prevention through closed-loop control that adapts to changing conditions in real-time.

AI summary
Introduced here are pressure-mitigation devices having improved adaptability or customizability to specific patients. An example pressure-mitigation device features modularity and dynamic usage of a number of individual chamber devices that can be assembled for a given body size, a given environment or substrate, and/or the like. Each modular chamber device includes at least one inflatable chamber and is configured for independent inflation and/or deflation of its at least one inflatable chamber. A set of modular chamber devices arranged (and attached) together can be operated in concert to provide a pressure-mitigation treatment for a body disposed atop and across the set of modular chamber devices.
