Enhanced Catheter System for Efficient and Safe Dialysis
Legal Citation
Summary of the Inventive Concept
An improved catheter system for dialysis, featuring advanced fixing means and sensors to ensure secure and efficient blood purification processes, while minimizing potential complications.
Background and Problem Solved
The original catheter patent has limitations in terms of fixing the catheter securely on the patient and ensuring proper placement. The new inventive concept addresses these limitations by introducing additional fixing means, adjustable fixing means, and sensors to monitor the catheter's position and detect potential complications.
Detailed Description of the Inventive Concept
The enhanced catheter system comprises a proximal end for introducing into a blood vessel, a distal end for extracting blood and introducing purified blood, and at least two fixing means. The first fixing means is configured to fix the catheter on a patient, while the second fixing means secures the catheter to a medical device. Additionally, the system includes an adjustable fixing means to adapt to different patient anatomies and at least one sensor to monitor the catheter's position and detect potential complications. The system also features a method for securing the catheter, comprising the steps of introducing the catheter into a blood vessel, extracting blood and introducing purified blood, and fixing the catheter on a patient using the advanced fixing means.
Novelty and Inventive Step
The new claims introduce the concept of multiple fixing means, adjustable fixing means, and sensors to ensure secure and efficient dialysis. These features are novel and non-obvious compared to the original patent, as they provide a more comprehensive and adaptive solution for catheter fixation and placement.
Alternative Embodiments and Variations
Alternative embodiments of the inventive concept could include different types of sensors, such as pressure sensors or optical sensors, to monitor the catheter's position and detect complications. Additionally, the adjustable fixing means could be implemented using different materials or mechanisms, such as shape-memory alloys or inflatable balloons.
Potential Commercial Applications and Market
The enhanced catheter system has significant commercial potential in the medical device industry, particularly in the field of dialysis. The system's advanced features and improved safety profile make it an attractive solution for healthcare providers and patients alike.
