Enhanced Extracorporeal Blood Treatment Apparatus with Advanced Temperature and Pressure Control
Legal Citation
Summary of the Inventive Concept
An improved extracorporeal blood treatment apparatus that incorporates advanced temperature and pressure control features, ensuring safer and more efficient patient treatment.
Background and Problem Solved
The original patent, 'Extracorporeal blood treatment apparatus', addresses the need for an apparatus that combines blood treatment with blood warming. However, it has limitations in terms of temperature and pressure control, which can lead to inadequate blood treatment and patient safety risks. The new inventive concept addresses these limitations by introducing advanced temperature and pressure control features.
Detailed Description of the Inventive Concept
The enhanced extracorporeal blood treatment apparatus comprises a blood treatment device, a blood warmer, and an extracorporeal blood circuit with a heating zone, temperature sensor, and control unit for regulating the temperature of the blood during treatment. Additionally, the apparatus includes a variable flow rate controller for adjusting the flow rate of the blood and a pressure sensor for monitoring the pressure of the blood. The control unit and blood pump are designed to maintain a predetermined temperature range and pressure range, ensuring optimal blood treatment conditions.
Novelty and Inventive Step
The new claims introduce the novel features of advanced temperature and pressure control, which are not present in the original patent. The inventive step lies in the integration of these features to create a more efficient, safer, and patient-centric extracorporeal blood treatment apparatus.
Alternative Embodiments and Variations
Alternative embodiments may include the use of different types of temperature sensors, pressure sensors, or control units. Variations may also involve the integration of additional features, such as air trapping devices or secondary post-infusion lines, to further enhance the apparatus's functionality.
Potential Commercial Applications and Market
The enhanced extracorporeal blood treatment apparatus has significant commercial potential in the medical device industry, particularly in the fields of hemodialysis, blood transfusion, and cardiovascular surgery. The target market includes hospitals, clinics, and medical research institutions.
