Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for collecting and draining fluids during medical procedures are inefficient, leading to spills and hazardous situations due to the inability to effectively contain and manage overflowing irrigant fluids, which can contaminate surfaces and pose risks to patients and staff.
Innovation Solution
A drain tray assembly with a fluid impermeable pan and a porous foam layer, featuring a sloping surface that directs fluids to a drainage outlet under gravity, along with a drape system to contain the area and prevent spills, allowing for efficient fluid collection and drainage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If suction tube devices or non-conforming containers are used to collect overflowing fluid, then some fluid collection is achieved, but efficient and safe fluid collection and drainage is insufficient
Solution Approach 1:
The device is divided into distinct functional segments: a collection pan for catching overflow, a porous layer for absorption and filtration, and a drainage system for controlled removal. This segmentation allows each component to perform its specific function optimally, improving overall fluid management efficiency and safety
Solution Approach 2:
A porous intermediate layer is introduced between the collection pan and the drainage outlet. This intermediary layer absorbs excess fluid, filters debris, and regulates flow, transforming the harsh overflow directly into controlled drainage and significantly improving safety and efficiency
2Object-affected harmful factors
If towels, sponges, and buckets are placed near the working site, then fluid containment is attempted, but spilling and contamination hazards remain
Solution Approach 1:
Multiple fluid management functions (collection, absorption, filtration, and drainage) are merged into a single integrated device. The collection pan, porous layer, and drainage system work together as one unit, eliminating the need for multiple separate items and reducing spill hazards while improving operational convenience
Solution Approach 2:
The device is designed to automatically manage fluid overflow through its own integrated structures. The porous layer self-regulates absorption and the drainage system self-drains collected fluid, reducing the need for manual intervention and minimizing contamination risks
3Productivity
If a sloping surface is used to direct fluids to the basin, then fluid drainage efficiency is improved, but the work surface angle must be less than the slope angle
Solution Approach 1:
Different portions of the device have different angular properties: the sloping surface has a steeper angle optimized for fluid drainage, while the work surface has a shallower angle optimized for procedural access. This local differentiation of angular quality allows both drainage efficiency and operational ease to be maximized simultaneously

Function Achieved in This Case
The solution effectively contains and drains fluids during medical procedures, reducing the risk of contamination and improving safety by ensuring efficient fluid management and collection, even when used on extended limbs or other body parts.
Implementation Method 1
The porous foam layer is structured to pass fluids from the top work surface to the sloping surface
Implementation Method 2
the sloping surface of the fluid impermeable pan is structured to convey fluids to the basin under the force of gravity for draining through the drain outlet

AI summary
A surgical drain tray assembly includes a fluid impermeable first layer and a porous second layer positioned on the fluid impermeable first layer. The fluid impermeable first layer includes a drain outlet, a basin, and a sloping surface angled toward the basin, the drain outlet being positioned within the basin. The porous second layer may be formed of a foam material and includes a top work surface. Fluids spilled onto the work surface pass through the porous second layer to the fluid impermeable first layer. The sloping surface of the fluid impermeable first layer conveys the fluids toward the basin for draining through the drainage outlet.
