Irrigation Drape Straining Assembly for Fluid Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical irrigation drapes face challenges in effectively managing and collecting irrigation fluid during medical procedures, particularly in surgeries involving heavy irrigation, leading to potential contamination and inefficiencies in fluid management.
Innovation Solution
The irrigation drape assembly includes a drape portion, a collection portion, an evacuation portion, and a straining assembly. The collection portion gathers irrigation fluid, the evacuation portion directs it towards an evacuation port, and the straining assembly filters out solids/semisolids, ensuring clean fluid is evacuated and preventing contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional surgical drapes are used, then the structure is simple and easy to manufacture, but fluid management capability is insufficient leading to spillage and contamination
Solution Approach 1:
The drape is divided into multiple functional segments: a collection portion with pouches for gathering irrigation fluid, an evacuation portion with channels for fluid removal, and a straining assembly with filters. Each segment performs a specific function, allowing the system to manage fluid effectively without requiring a completely redesigned complex structure.
Solution Approach 2:
The drape integrates multiple functions into a single device: fluid collection through adhesive-pouched sections, fluid evacuation through integrated channels and ports, and particle filtration through straining assemblies. This multi-functionality resolves the contradiction by providing comprehensive fluid management while maintaining a unified, manageable structure.
2Object-affected harmful factors
If no straining assembly is used, then the device complexity is reduced, but solids/semisolids enter the evacuation port causing contamination
Solution Approach 1:
A straining assembly with a straining surface acts as an intermediary component between the fluid collection area and the evacuation port. This mediator captures solids and semisolids through adhesion and filtration, preventing them from entering the evacuation system while maintaining a relatively simple overall device structure.
Solution Approach 2:
The straining assembly incorporates porous or mesh-like structures that allow fluid to pass through while blocking solids and semisolids. This use of porous materials provides effective filtration without requiring complex mechanical filtering systems, thus reducing overall device complexity while lowering contamination risk.
3Productivity
If irrigation fluid is not collected, then the system is simpler, but fluid spillage occurs reducing operational efficiency
Solution Approach 1:
The collection portion is merged with the main drape structure through adhesive bonding, creating an integrated fluid management system. The pouches are directly attached to the drape, eliminating the need for separate collection containers or complex piping systems, thus improving operational efficiency without significantly increasing device complexity.
Solution Approach 2:
The adhesive-pouched collection portion automatically captures and contains irrigation fluid as it flows during the procedure, without requiring active intervention or additional collection devices. The fluid is self-contained within the pouches, preventing spillage and maintaining operational efficiency with minimal added complexity.

AI summary
An irrigation drape assembly includes: a drape portion configured to be positioned beneath a body portion on which a medical procedure is being performed; a collection portion configured to collect irrigation fluid produced during the medical procedure on the body portion, thus defining collected irrigation fluid; a evacuation portion coupled to the collection portion and configured to receive the collected irrigation fluid and direct the collected irrigation fluid toward an evacuation port included in the evacuation portion; and a straining assembly configured to strain solids/semisolids from the collected irrigation fluid and prevent the solids/semisolids from entering the evacuation port, thus defining strained irrigation fluid.
