Inflatable Chamber Pressure Control for Pressure Injury Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional alternating pressure technologies fail to effectively control the spatial relationship between individuals and support surfaces, leading to pressure injuries and related complications in mobility-impaired or immobilized individuals.
Innovation Solution
Inflatable perfusion enhancement apparatuses with selectively inflatable chambers, controlled by a controller device, dynamically vary pressure distribution across the body by inflating or deflating chambers to relocate pressure points, mimicking natural micro-adjustments and preventing ischemia.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional alternating pressure technologies are used, then pressure distribution is varied over time, but the spatial relationship between the individual and support surface cannot be controlled, leading to pressure injuries
Solution Approach 1:
The support surface is divided into multiple independently controllable zones or regions, each capable of being inflated or deflated separately. This segmentation allows precise control over the spatial relationship between the individual and support surface, enabling targeted pressure relief at specific anatomical locations while maintaining overall support, thereby preventing pressure injuries effectively
2Reliability
If inflatable chambers are used to relocate pressure points, then tissue perfusion is enhanced and pressure injuries are prevented, but device complexity increases
Solution Approach 1:
Multiple inflatable chambers are merged into an integrated system with centralized control, where chambers work cooperatively to relocate pressure points. The control system coordinates chamber inflation and deflation sequences to achieve effective pressure redistribution while managing complexity through systematic integration rather than independent operation of each chamber
3Reliability
If pressure points are continuously relocated to prevent ischemia, then tissue perfusion is enhanced, but energy consumption increases
Solution Approach 1:
The inflatable chambers operate in periodic cycles of inflation and deflation, creating rhythmic pressure variations that relocate pressure points over time. This periodic action prevents continuous ischemia by ensuring no single area remains under pressure indefinitely, while the cyclic nature allows energy recovery and reduces overall energy consumption compared to continuous operation

AI summary
Introduced here are methods, apparatuses, and systems for mitigating the contact pressure applied to a human body by the surface of an object, such as a chair, bed, or table. A pressure-mitigation apparatus can include a series of chambers whose pressure can be individually varied. When placed between a patient and a contact surface, a controller can vary the contact pressure on the human body by controllably inflating one or more chambers, deflating one or more chambers, or any combination thereof. By monitoring the pressure in each chamber over time, the controller can also gain an enhanced understanding of movement(s) performed by the human body when positioned on the pressure-mitigation apparatus.
