This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,768.

Summary of the Inventive Concept

A versatile filtering needle assembly with a seal plug and filter, adapted for various industries, including agricultural irrigation, aerospace, industrial manufacturing, medical research, and environmental monitoring.

Background and Problem Solved

The original patent for a filtering needle assembly with a seal plug primarily focused on administering liquid payloads in medical settings. However, this limited the technology's potential applications. The new inventive concept addresses this limitation by expanding the filtering needle assembly's use cases to tackle distinct challenges in various industries.

Detailed Description of the Inventive Concept

The filtering needle assembly, comprising a needle and connector portion, a filter needle cap body, a seal plug, and a filter, is adapted for diverse applications. In agricultural irrigation systems, the assembly removes impurities from irrigation water. In aerospace, it filters fuel for aircraft engines. In industrial manufacturing, it purifies chemicals. In medical research, it filters biological samples. In environmental monitoring, it removes pollutants from air. The seal plug's design, including its dome shape, hollow interior, and rib rings, ensures a secure and efficient filtering process.

Novelty and Inventive Step

The new inventive concept's novelty lies in its application of the filtering needle assembly to entirely different industries, solving unique problems and overcoming distinct challenges. The inventive step is the recognition of the assembly's versatility and its adaptation to address various industrial needs.

Alternative Embodiments and Variations

Alternative embodiments may include modifying the filter needle cap body's material or design to accommodate specific industry requirements. Variations could involve integrating additional components, such as sensors or valves, to enhance the filtering process or provide real-time monitoring.

Potential Commercial Applications and Market

The diversified filtering needle assembly has significant commercial potential across multiple industries, including agricultural technology, aerospace, industrial manufacturing, medical research, and environmental monitoring. The market for such a versatile technology is substantial, with potential customers including companies, research institutions, and government agencies.

Field of Art

Medical device engineering, specifically needle assemblies and filtration systems for medical and industrial applications, requiring expertise in mechanical design, fluid dynamics, and materials science

Person of Ordinary Skill (PHOSITA) Profile
