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. 11,857,761.

Summary of the Inventive Concept

The present disclosure relates to a novel system integrating a check valve with advanced technologies such as sensors, machine learning, blockchain, and IoT to optimize fluid flow and minimize particulate accumulation in medical devices, thereby reducing contamination risks and improving patient safety.

Background and Problem Solved

The original check valve patent (FIELD OF THE INVENTION) addressed the need for a reliable check valve in IV sets. However, it did not provide a comprehensive solution for monitoring and controlling fluid flow, particulate accumulation, and contamination risks. The present inventive concept solves this problem by synergistically combining the check valve with distinct technologies to create a more powerful system.

Detailed Description of the Inventive Concept

The inventive concept comprises a check valve with a wiping extension, which is integrated with various advanced technologies such as sensors, machine learning algorithms, blockchain-based tracking systems, and IoT-enabled sensors. These components work together to detect particulate accumulation, analyze fluid flow data, predict optimal wiping extension actuation times, and provide real-time insights on fluid flow optimization and contamination risk reduction. The system can be implemented in various medical devices, including IV sets, to minimize contamination risks and improve patient safety.

Novelty and Inventive Step

The new claims introduce a synergistic combination of the check valve with advanced technologies, which is not obvious from the original patent. The integration of these distinct technologies enables real-time monitoring and control of fluid flow, particulate accumulation, and contamination risks, thereby providing a novel and non-obvious solution.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include the use of different types of sensors, machine learning algorithms, or blockchain-based systems. Additionally, the system could be adapted for use in other medical devices or industries, such as dialysis machines or industrial fluid handling systems.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in the medical device industry, particularly in the IV set market. The system's ability to minimize contamination risks and improve patient safety could lead to widespread adoption and generate substantial revenue. Additionally, the technology could be licensed to other industries, further expanding its market potential.
