Dual Therapy Unit Manifold for Continuous Negative Pressure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current negative-pressure wound therapy systems face challenges in managing large wounds that require high fluid removal rates and redundancy to prevent loss of negative pressure during canister emptying, often leading to discomfort, noise, and increased energy consumption.
Innovation Solution
A system comprising two therapy units fluidly coupled to a single dressing, with synchronized operation to alternately apply negative pressure and fluids, ensuring continuous treatment and fluid management, even when one canister is emptied.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple therapy units are used to increase fluid removal capacity, then productivity is improved, but device complexity increases
Solution Approach 1:
The system divides the fluid removal function into multiple independent therapy units, each with its own pump and canister. This segmentation allows parallel operation to increase fluid removal capacity while keeping each unit relatively simple and modular.
Solution Approach 2:
Multiple therapy units are combined and synchronized through a control system that coordinates their operation. The manifold merges the fluid pathways from multiple units into a single dressing interface, enabling collective fluid removal while maintaining individual unit independence.
2Reliability
If therapy units operate continuously to maintain negative pressure, then reliability is improved, but energy consumption increases
Solution Approach 1:
The system uses periodic cycling of multiple therapy units where units alternate between active and inactive states. While one unit operates, another can be emptied or serviced, ensuring continuous negative pressure without requiring all units to run continuously, thus reducing overall energy consumption.
Solution Approach 2:
The synchronized operation of multiple units ensures that negative pressure is continuously maintained at the dressing interface even when individual units cycle off. The overlap in operation cycles guarantees no interruption in therapeutic effect while allowing energy-saving idle periods for each unit.
3Reliability
If canisters are emptied sequentially to manage fluid volume, then loss of negative pressure is prevented, but treatment time is lost
Solution Approach 1:
The fluid collection system is segmented into multiple independent canisters associated with different therapy units. This allows one canister to be emptied while another continues collecting fluid, eliminating the need to stop therapy for canister emptying and maintaining continuous negative pressure.
Solution Approach 2:
The system is configured in advance with multiple canisters and synchronized cycling so that a second canister is ready to take over before the first is emptied. This preliminary arrangement ensures seamless transition without therapy interruption.

Function Achieved in This Case
This configuration enhances fluid removal capacity, maintains constant negative pressure, reduces patient discomfort, and prevents therapy disruptions, while using standard therapy units to treat severe wounds effectively.
Implementation Method 1
reducing pressure in proximity to a tissue site can augment and accelerate growth of new tissue at the tissue site
Implementation Method 2
instillation of topical treatment solutions over a wound bed can be combined with negative-pressure therapy to further promote wound healing by loosening soluble contaminants in a wound bed and removing infectious material
