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. 11,857,774.

Summary of the Inventive Concept

The present inventive concept integrates the original intravenous tubing venting assembly with distinct technologies, such as AI, IoT, blockchain, and novel materials, to create a more powerful system for removing air bubbles from intravenous tubing, ensuring secure, efficient, and transparent fluid delivery to patients.

Background and Problem Solved

The original patent disclosed a venting valve for removing air bubbles from intravenous tubing. However, this invention had limitations, such as the need for manual operation and the potential for airlocks and bacterial growth. The new inventive concept addresses these limitations by leveraging advanced technologies to create a more efficient, secure, and patient-centric system.

Detailed Description of the Inventive Concept

The new inventive concept comprises a venting valve connected to an AI-powered fluid flow sensor, which detects air bubbles in the tubing and triggers the venting valve to open, allowing air bubbles to escape while maintaining fluid flow to a patient. Additionally, the system integrates with a blockchain-based supply chain management system to track fluid flow and air bubble removal, ensuring secure and transparent fluid delivery to patients. Furthermore, the system includes an IoT-enabled sensor that monitors fluid flow and air bubble removal in real-time, transmitting data to a cloud-based platform for analysis and optimization. The system also features a novel material-based air extraction device, comprising a chamber formed of a porous, breathable material that allows air bubbles to escape while maintaining fluid flow, wherein the material is treated with antimicrobial agents to prevent bacterial growth. Finally, the system incorporates a hybrid air extraction device, comprising a mechanical air extraction component integrated with an AI-powered fluid flow prediction algorithm, which predicts fluid flow rates and air bubble formation, optimizing air bubble removal and fluid delivery to patients.

Novelty and Inventive Step

The new inventive concept introduces a synergistic combination of advanced technologies, including AI, IoT, blockchain, and novel materials, which provides a more efficient, secure, and patient-centric system for removing air bubbles from intravenous tubing. The integration of these technologies with the original venting valve creates a new, more powerful system that is not obvious from the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include variations in the AI-powered fluid flow sensor, such as using machine learning algorithms to predict air bubble formation. Another variation could be the use of different blockchain platforms for supply chain management. Additionally, the IoT-enabled sensor could be replaced with other real-time monitoring technologies, such as sensors using radio-frequency identification (RFID) or near-field communication (NFC). The novel material-based air extraction device could also be modified to use different materials or treatments to prevent bacterial growth.

Potential Commercial Applications and Market

The new inventive concept has significant commercial potential in the healthcare industry, particularly in hospitals and clinics where intravenous fluid delivery is a critical component of patient care. The system's ability to ensure secure, efficient, and transparent fluid delivery to patients makes it an attractive solution for healthcare providers. The market for this technology is expected to grow as the need for advanced medical devices and digital healthcare solutions increases.
