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. 11,857,734.

Summary of the Inventive Concept

An advanced catheter system that integrates real-time occlusion detection, automated flushing, and machine learning algorithms to reduce catheter-related complications and improve patient safety.

Background and Problem Solved

The original patent, 'Catheter system clamp, systems, and methods', addressed the need for efficient flushing of catheter assemblies to prevent occlusion. However, it had limitations in detecting potential occlusion and relied on manual flushing protocols. The new inventive concept addresses these limitations by incorporating real-time occlusion detection, automated flushing, and machine learning algorithms to optimize catheter performance and patient safety.

Detailed Description of the Inventive Concept

The enhanced catheter system comprises a catheter assembly with a built-in pressure sensor, an onboard computing system with machine learning algorithms, and an automated flushing module. The pressure sensor detects potential occlusion and alerts clinicians in real-time, while the machine learning algorithms analyze sensor data to predict occlusion risk. The automated flushing module optimizes flushing protocols based on patient-specific data and catheter type, ensuring efficient and safe infusion therapy. The system also includes a catheter adapter with an integrated valve that automatically closes upon detection of blood flashback, minimizing the risk of catheter-related complications.

Novelty and Inventive Step

The new inventive concept introduces real-time occlusion detection, automated flushing, and machine learning algorithms, which are not present in the original patent. These advancements provide a significant improvement in catheter performance, patient safety, and overall efficiency.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept may include variations in sensor types, machine learning algorithms, and automated flushing protocols. For example, the system could be adapted for use with different types of catheters, or integrated with electronic health records to provide a more comprehensive patient care platform.

Potential Commercial Applications and Market

The enhanced catheter system has significant commercial potential in the medical device industry, particularly in the areas of infusion therapy, patient safety, and healthcare technology. The system's ability to reduce catheter-related complications and improve patient outcomes makes it an attractive solution for hospitals, clinics, and healthcare providers.
