Disposable Irrigation Basin with Suction Trough for Fluid Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current extremity irrigation trays are unstable, leading to poor containment of fluid, contamination, and exposure to blood-borne pathogens, which increases cleanup costs, time management issues, and resource consumption.
Innovation Solution
A disposable irrigation basin with an internal extremity resting slope and a built-in step-off groove that anchors to the edge of an examination platform, allowing fluids to drain into a series of troughs and be safely evacuated via an integrated suction portal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current extremity irrigation trays are used, then fluid containment is poor, but stability is insufficient
Solution Approach 1:
The basin is divided into multiple functional zones: an extremity support surface for patient comfort, a fluid collection region with sloped surfaces, and a suction interface. This segmentation allows each zone to perform its specific function optimally, improving overall fluid containment while maintaining stability.
Solution Approach 2:
The basin utilizes three-dimensional sloped surfaces and depth variations to direct fluid flow toward the suction portal. By creating a gradient from the extremity support area to the collection region, the design improves fluid containment through gravitational flow paths without compromising basin stability.
2Loss of time
If unstable basins are used, then setup time is reduced, but contamination risk increases
Solution Approach 1:
The basin is designed as a disposable single-use device that can be quickly set up and then discarded after one procedure. This eliminates the need for complex stabilization mechanisms while ensuring that each new procedure uses a clean, stable basin, thereby reducing pathogen exposure without increasing room turnover time.
Solution Approach 2:
The integrated suction portal and self-draining sloped design allow the basin to automatically manage fluid removal without requiring additional manual intervention or complex stabilization systems. This self-managing capability reduces both setup time and contamination risk.
3Quantity of substance
If large amounts of irrigation fluid are used, then wound cleaning effectiveness is improved, but spillage increases
Solution Approach 1:
The basin integrates a suction portal that uses negative pressure (suction) to actively remove irrigation fluid, debris, and contaminants from the procedure area. This hydraulic control system allows large volumes of irrigation fluid to be used for effective wound cleaning while preventing spillage by continuously evacuating fluid through the suction interface.
Solution Approach 2:
The sloped three-dimensional surface design creates natural fluid flow paths that direct irrigation fluid toward the suction portal. This geometric configuration ensures that even large volumes of irrigation fluid remain contained and directed, preventing spillage while maintaining effective wound irrigation.
4Reliability
If modified trays are used to improve stability, then fluid containment improves, but device complexity increases
Solution Approach 1:
The basin combines multiple functions into a single integrated structure: extremity support, fluid collection, and suction interface are all incorporated into one molded piece. This merging eliminates the need for multiple separate components or modifications while achieving superior fluid containment through the unified design with sloped surfaces and integrated suction portal.
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 basin effectively contains fluids and reduces exposure to pathogens and contamination, decreasing cleanup costs and allowing for quick and thorough disposal, while ensuring safe and efficient execution of extremity procedures.
Implementation Method 1
The contaminated fluid may then travel via suction into Food and Drug Administration (FDA) approved suction canister(s)
Implementation Method 2
the distal portion of the basin declines (by design) and is held in place by the body weight of the extremity

AI summary
A disposable basin for extremity procedures, irrigation and lavage in the operating room, treatment clinic or ward allows the extremity to rest comfortably, safely, and securely inside the basin, allowing the surgeon, physician, clinician, and or provider ease of access within a contained protective barrier. Contaminated fluid safely and efficiently drains into an integrated suction trough via the intrinsic design of the basin, resulting in decreased exposure to pathogens, containment of contamination, ease of execution and disposal, and cost savings.
