Advanced Filtering Needle Assembly with Nanoseal Plug
Legal Citation
Summary of the Inventive Concept
A next-generation filtering needle assembly that incorporates a nanoseal plug for enhanced safety and convenience, enabling more efficient and reliable liquid payload administration.
Background and Problem Solved
The original patent disclosed a filtering needle assembly with a seal plug, which, while effective, has limitations in terms of needle tip sealing and filter maintenance. The new inventive concept addresses these limitations by introducing a nanoseal plug, which provides a more secure and reliable seal, and enables self-cleaning capabilities.
Detailed Description of the Inventive Concept
The advanced filtering needle assembly comprises a self-cleaning needle and connector portion, a filter needle cap body, a nanoseal plug, and a filter. The nanoseal plug is adapted to seal the needle tip upon removal of the filter needle cap body, ensuring a secure and reliable connection. The self-cleaning feature of the needle and connector portion enables efficient filter maintenance, reducing the risk of contamination and clogging. The filter is designed to filter the liquid payload in both forward and reverse directions, providing enhanced flexibility and convenience.
Novelty and Inventive Step
The new claims introduce the nanoseal plug, which is a novel and non-obvious feature compared to the original patent. The nanoseal plug's ability to seal the needle tip and enable self-cleaning capabilities provides a significant improvement over the original design.
Alternative Embodiments and Variations
Alternative embodiments of the inventive concept could include different nanoseal plug materials, shapes, or sizes, as well as varying filter designs and configurations. Additionally, the self-cleaning feature could be implemented using different mechanisms, such as ultrasonic cleaning or mechanical scrubbing.
Potential Commercial Applications and Market
The advanced filtering needle assembly has significant commercial potential in the medical device industry, particularly in the areas of vaccine administration, pharmaceutical delivery, and biotechnology research. The enhanced safety, convenience, and reliability of the new design make it an attractive solution for healthcare professionals and researchers.
