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. 11,857,714.

Summary of the Inventive Concept

A next-generation fluid balance management system that leverages advanced predictive analytics, machine learning, and real-time sensor data to optimize fluid flow rates and ensure optimal fluid balance during biological fluid procedures.

Background and Problem Solved

The original patent disclosed systems and methods for monitoring and controlling fluid balance in medical procedures, but these systems were limited by their inability to dynamically adjust to changing patient conditions and fluid volume requirements. The new inventive concept addresses this limitation by introducing advanced analytics and automation capabilities to ensure optimal fluid balance and reduce the risk of fluid imbalance-related complications.

Detailed Description of the Inventive Concept

The new inventive concept comprises a predictive analytics module that forecasts fluid volume requirements based on real-time patient data, a fluid management module that adjusts fluid flow rates accordingly, and a control module that dynamically adjusts fluid flow rates and photoactivation intensity based on real-time fluid balance data. The system may also include interchangeable fluid management modules for different biological fluid procedures, each module comprising a dedicated fluid circuit and a controller configured to optimize fluid balance for the specific procedure. Additionally, the system may be integrated with a cloud-based platform for remote monitoring and control of fluid balance during biological fluid procedures.

Novelty and Inventive Step

The new claims introduce a paradigm shift in fluid balance management by leveraging advanced analytics and automation capabilities to optimize fluid flow rates and ensure optimal fluid balance. The predictive analytics module, fluid management module, and control module work in concert to provide a level of precision and adaptability not possible with the original patent's systems and methods.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept may include the use of different types of sensors, such as pressure sensors or flow sensors, to monitor fluid balance. Additionally, the system may be integrated with other medical devices, such as dialysis machines or blood pumps, to provide a comprehensive fluid management solution.

Potential Commercial Applications and Market

The new inventive concept has significant commercial potential in the medical device industry, particularly in the areas of blood processing, dialysis, and extracorporeal photopheresis. The system's ability to optimize fluid balance and reduce the risk of fluid imbalance-related complications makes it an attractive solution for hospitals, clinics, and medical research institutions.
