Enhanced Intravenous Tubing Venting Assembly
Legal Citation
Summary of the Inventive Concept
An innovative venting system for intravenous tubing that improves patient safety, reduces airlocks, and enhances fluid delivery efficiency by incorporating advanced features such as pressure-activated valves, air bubble detection, and self-cleaning mechanisms.
Background and Problem Solved
The original patent for the intravenous tubing venting assembly addressed the issue of air bubbles in IV tubing, but had limitations in terms of air removal efficiency, fluid flow turbulence, and potential clogging. The new inventive concept builds upon the original patent by introducing direct improvements and enhancements to overcome these limitations.
Detailed Description of the Inventive Concept
The enhanced intravenous tubing venting assembly comprises a venting valve with a pressure-activated mechanism that opens to allow air bubbles to escape along a venting path while preventing fluid passage through the venting path when a predetermined pressure threshold is exceeded. Additionally, the system includes an air extraction device in-line with the intravenous tubing, which provides a pathway for air removal from the fluid flow through the tubing. The branch is oriented to minimize turbulence and optimize air removal. Furthermore, the venting valve is equipped with a sensor that detects air bubbles in the intravenous tubing and triggers the opening of the venting valve. The system also incorporates a self-cleaning mechanism that removes debris and contaminants from the venting path to ensure consistent air removal and prevent clogging.
Novelty and Inventive Step
The new inventive concept introduces several novel features that differentiate it from the original patent, including the pressure-activated valve, air bubble detection, and self-cleaning mechanism. These advancements provide a significant improvement in air removal efficiency, fluid flow turbulence reduction, and patient safety.
Alternative Embodiments and Variations
Alternative embodiments of the inventive concept could include different valve designs, such as solenoid-activated valves or membrane-based valves. Additionally, the air extraction device could be replaced with other air removal mechanisms, such as ultrasonic or vacuum-based systems. The self-cleaning mechanism could also be modified to use different cleaning agents or frequencies.
Potential Commercial Applications and Market
The enhanced intravenous tubing venting assembly has significant commercial potential in the medical device industry, particularly in the areas of patient safety, fluid delivery efficiency, and healthcare cost reduction. The target market includes hospitals, clinics, and medical research institutions.
