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

The present inventive concept relates to a next-generation filtering needle assembly that incorporates adaptive filtering capabilities, real-time sensor feedback, and artificial intelligence to optimize the removal of contaminants from liquid payloads, providing a significant improvement over existing filtering technologies.

Background and Problem Solved

The original patent for the Filtering Needle Assembly with Seal Plug addressed the need for a reliable and efficient filtering system for administering liquid payloads. However, the original design had limitations in terms of filter replaceability, adaptability to different liquid payloads, and real-time monitoring and adjustment of the filtering process. The new inventive concept addresses these limitations by introducing an adaptive filtering system that can be integrated with sensors, microcontrollers, and artificial intelligence to provide a more efficient, effective, and intelligent filtering solution.

Detailed Description of the Inventive Concept

The adaptive filtering needle assembly comprises a replaceable filter cartridge, a sensor to detect contaminants in the liquid payload, a microcontroller to process sensor data and adjust the filtering process, and a communication module to enable real-time monitoring and control. The filter cartridge can be swapped with different filter types or sizes based on the specific liquid payload being administered, ensuring optimal filtering performance. The sensor and microcontroller work together to detect contaminants and adjust the filtering process in real-time, while the artificial intelligence analyzes data from the sensor and adjusts the filtering process to optimize the removal of contaminants. The modular design of the filtering needle assembly allows for easy replacement of filter cartridges and integration with different sensors and microcontrollers.

Novelty and Inventive Step

The new claims introduce several novel and non-obvious features, including the adaptive filtering capability, real-time sensor feedback, and artificial intelligence integration. These features provide a significant improvement over existing filtering technologies and address the limitations of the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include different sensor types, microcontroller architectures, and artificial intelligence algorithms. Additionally, the filtering needle assembly could be integrated with other medical devices, such as syringes or infusion pumps, to provide a more comprehensive solution for liquid payload administration.

Potential Commercial Applications and Market

The adaptive filtering needle assembly has significant commercial potential in the medical industry, particularly in the areas of vaccine administration, pharmaceutical delivery, and biotechnology research. The target market includes hospitals, clinics, and research institutions, as well as pharmaceutical and biotechnology companies.
