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. 11,857,715.

Summary of the Inventive Concept

This invention improves the original extracorporeal blood treatment apparatus by integrating real-time temperature and pressure control, ensuring safer and more efficient patient treatment.

Background and Problem Solved

The original patent's extracorporeal blood treatment apparatus had limitations in maintaining optimal blood temperature and pressure during treatment. This new concept addresses these limitations by incorporating advanced sensors and control systems.

Detailed Description of the Inventive Concept

The enhanced apparatus features a blood treatment device, a blood warmer, and an extracorporeal blood circuit with a blood withdrawal line and a blood return line. The blood return line includes a heating zone with a temperature sensor and a controller for adjusting the temperature based on the sensed temperature. Additionally, the apparatus includes a pressure sensor and a controller for adjusting the pressure of the blood return line based on the sensed pressure. The system also comprises a flow sensor and a controller for adjusting the flow rate of the blood return line based on the sensed flow rate.

Novelty and Inventive Step

The new claims introduce real-time temperature and pressure control, which is not present in the original patent. This innovation enables more precise and efficient treatment, improving patient safety and outcomes.

Alternative Embodiments and Variations

Alternative embodiments could include integrating the temperature and pressure control systems into a single unit, or using different types of sensors and controllers. Variations could also include adapting the apparatus for use in different medical settings or for treating specific blood disorders.

Potential Commercial Applications and Market

The enhanced extracorporeal blood treatment apparatus has significant commercial potential in the medical device industry, particularly in hospitals and clinics performing blood treatments. The improved safety and efficiency of the apparatus could lead to increased adoption and market share.
