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. 11,857,711.

Summary of the Inventive Concept

The present inventive concept relates to an improved blood treatment system that incorporates real-time monitoring and adaptive control to optimize treatment efficiency, safety, and outcomes. The system integrates advanced sensors, machine learning algorithms, and automated control mechanisms to ensure precise and responsive adjustments to treatment parameters.

Background and Problem Solved

The original patent disclosed a method for setting a control device or a closed-loop control device of a blood treatment apparatus. However, the existing patent has limitations in terms of real-time monitoring and adaptive control, which can lead to suboptimal treatment outcomes and safety risks. The present inventive concept addresses these limitations by introducing advanced monitoring and control capabilities to ensure optimal treatment parameters and minimize the risk of anomalies.

Detailed Description of the Inventive Concept

The enhanced blood treatment system comprises a blood pump, dialysis liquid inlet and outlet lines, and a dialysis liquid pump. The system is equipped with advanced sensors that monitor the blood treatment process in real-time, providing data on flow rates, pressure, and other critical parameters. This data is fed into a control device that utilizes machine learning algorithms to analyze the data and adjust treatment parameters accordingly. The system can automatically adjust the flow rate of dialysis liquid, blood pump flow rate, and treatment duration to achieve optimal treatment outcomes. Additionally, the system features a safety feature that can automatically shut off the blood pump in response to detected anomalies, ensuring the safety of patients.

Novelty and Inventive Step

The present inventive concept introduces the novel combination of real-time monitoring and adaptive control to optimize blood treatment parameters. The use of machine learning algorithms to analyze real-time data and adjust treatment parameters in real-time is a significant departure from the existing patent, which relied on predetermined correction factors. This inventive step enables the system to respond dynamically to changing treatment conditions, ensuring optimal treatment outcomes and minimizing safety risks.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include the use of different types of sensors, such as optical or acoustic sensors, to monitor the blood treatment process. Additionally, the system could be integrated with other medical devices, such as patient monitoring systems or electronic health records, to provide a more comprehensive treatment platform. Variations of the system could also be designed for specific treatment modalities, such as hemodialysis or hemofiltration.

Potential Commercial Applications and Market

The enhanced blood treatment system has significant commercial potential in the medical device industry, particularly in the markets for hemodialysis and blood treatment equipment. The system's ability to optimize treatment outcomes and minimize safety risks makes it an attractive solution for healthcare providers and patients. The market for blood treatment equipment is expected to grow significantly in the coming years, driven by an increasing demand for effective and efficient treatment options.
