Pierceable Septum Container Assembly for Leak-Proof Fluid Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid container devices for wet chemistry instruments are costly, inefficient, and environmentally impactful, with a need for precise fluid distribution and reduced leakage, particularly in high-pressure applications like HPLC instruments.
Innovation Solution
A fluid container device with a septum member that allows repeated piercing by a needle, using a polymer septum to seal and compress, ensuring leak-proof delivery and compatibility with pressurized environments, combined with a reusable second container for efficient fluid transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional fluid container device is used, then fluid storage is provided, but fluid leakage and drips occur during storage and delivery
Solution Approach 1:
A septum member is introduced as an intermediary component between the vessel opening and the external environment. The septum member includes a needle-penetrable septum portion that seals the opening while allowing controlled access, preventing leakage and drips during fluid storage and delivery operations.
2Ease of operation
If a needle-penetrable septum is used, then repeated piercing is enabled, but sealing reliability may be compromised
Solution Approach 1:
The septum member is designed with specific material properties and structural parameters that allow it to maintain seal integrity despite repeated piercing. The needle-penetrable septum portion is made from materials and constructed in a manner that enables it to be repeatedly pierced by a needle while maintaining its sealing function throughout multiple access cycles.
3Productivity
If existing fluid container devices are used, then fluid delivery is achieved, but costs are high and environmental impact is increased
Solution Approach 1:
The fluid container device is segmented into distinct functional components: a vessel for fluid storage, a container assembly housing, and a septum member for sealed access. This segmentation allows each component to be optimized independently for its specific function, improving overall fluid delivery efficiency while enabling cost-effective manufacturing through specialized production of individual parts.
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 device provides precise and leak-proof fluid delivery, reduces waste, and lowers costs by using a reusable second container, while maintaining compatibility with complex wet chemistry instruments.
Implementation Method 1
The septum may be at least partially compressed to facilitate closure of passages formed by puncturing the septum with such an access mechanism.
Implementation Method 2
a polymer septum to seal and compress, ensuring leak-proof delivery
