Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional kits for containing and draining biological fluids face issues with contamination risks and the use of sharp elements during fluid separation and drainage processes.
Innovation Solution
A kit comprising a barrel, piston assembly with a shut-off valve, removable elements, drainage elements, and interacting elements that allow for safe aspiration, separation, and drainage of biological fluids without using needles or sharp elements, utilizing a sealing mechanism to prevent contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional kits use sharp elements like needles for fluid separation and drainage, then fluid separation can be achieved, but contamination risk increases and safety decreases
Solution Approach 1:
The patent removes sharp elements (needles) from the system entirely. The drainage element uses a blunt tip with a lateral opening that engages with the shut-off valve without requiring penetration, thereby extracting the harmful sharp component while maintaining fluid access capability
Solution Approach 2:
The shut-off valve acts as an intermediary mechanism between the external drainage element and the biological fluid. Instead of direct needle-to-fluid contact, the valve mediates fluid release through a controlled opening, eliminating the need for sharp penetration while maintaining separation functionality
2Productivity
If conventional kits enable fluid drainage, then constituent separation is achieved, but contamination of the biological fluid occurs
Solution Approach 1:
The system segments the fluid access pathways into distinct functions: the first opening (with sealing element) for fluid intake and the second opening (via shut-off valve) for controlled drainage. This segmentation allows independent control of each pathway, enabling drainage without compromising the integrity of the main fluid container
Solution Approach 2:
The shut-off valve is pre-configured in a closed position that seals the second opening before drainage begins. This preliminary sealing action prevents any potential contamination before the drainage process starts, and the valve remains sealed until intentionally opened through proper engagement with the drainage element

AI summary
For containing a biological fluid and draining a constituent of the biological fluid, a kit includes a barrel, a piston assembly, a removable element, which is configured to move the piston assembly, a drainage element, which interacts with the piston assembly, and an interacting element, which interacts with the piston assembly. The kit allows for fluid separation without risk of contamination from the biological fluid itself or contamination of the biological fluid itself. Further, the kit offers the advantage of involving no needles or other sharp elements.
