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 synergistic combination of a check valve with advanced technologies, such as artificial intelligence, blockchain, IoT, and nanomaterials, to create a more reliable, efficient, and secure medical fluid administration system.

Background and Problem Solved

The original check valve patent, while effective in preventing backflow, had limitations in detecting and addressing particulate accumulation, contamination, and fluid flow anomalies. The new inventive concept addresses these limitations by integrating the check valve with distinct technologies to enhance fluid flow, detect potential issues, and ensure authenticity and security of medical fluids.

Detailed Description of the Inventive Concept

The new system comprises a check valve incorporating a wiping extension, which can be triggered automatically by an artificial intelligence module to unclog the valve. The system can also integrate a blockchain-based authentication system to verify the authenticity of medical fluid and detect potential contamination. Additionally, a sensor module connected to an IoT network can monitor fluid flow and detect anomalies, generating real-time alerts. Furthermore, the valve member can be coated with nanomaterials to reduce particulate accumulation and enhance fluid flow. The system can also be integrated with machine learning algorithms to predict and prevent particulate accumulation based on historical usage patterns and environmental factors.

Novelty and Inventive Step

The new claims introduce a synergistic combination of the check valve with advanced technologies, providing a more comprehensive and effective solution for medical fluid administration. The inventive step lies in the integration of these distinct technologies to create a more reliable, efficient, and secure system.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include varying the type of artificial intelligence module, blockchain-based authentication system, or IoT network used. Additionally, the system could be adapted for use in other medical fluid administration applications, such as dialysis or chemotherapy.

Potential Commercial Applications and Market

The intelligent check valve system has significant commercial potential in the medical device industry, particularly in the IV set market. The system's enhanced reliability, efficiency, and security features make it an attractive solution for hospitals, clinics, and other healthcare providers.
