Summary of the Inventive Concept

A wearable, non-invasive, and real-time fluid sensor system for detecting air bubbles in fluid delivery conduits, predicting potential health risks, and enabling smart fluid management in medical environments.

Background and Problem Solved

The original fluid sensor patent, while effective, has limitations in terms of size, invasiveness, and real-time monitoring capabilities. The new inventive concept addresses these limitations by introducing a wearable, miniature, and non-invasive fluid sensor system that enables real-time air bubble detection and smart fluid management.

Detailed Description of the Inventive Concept

The new inventive concept comprises a wearable device having an integrated fluid sensor, a data analytics module, and a communication module. The fluid sensor detects air bubbles in a fluid delivery conduit using a nanoscale ultrasonic transmitter and a pressure sensor integrated on a single chip. The data analytics module predicts potential health risks based on the detected air bubbles and sends alerts to a medical professional through the communication module. The system enables real-time monitoring of fluid delivery, automatic adjustment of fluid flow rate, and smart fluid management in medical environments.

Novelty and Inventive Step

The new inventive concept introduces a wearable, non-invasive, and real-time fluid sensor system that enables smart fluid management, which is a significant departure from the original patent's invasive and size-limited design. The use of nanoscale ultrasonic transmitters and machine learning algorithms for real-time air bubble detection and prediction of potential health risks is a novel and non-obvious advancement.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept include a fluid sensor patch with a flexible ultrasonic transmitter and a pressure sensor, a system for smart fluid management in a hospital using a network of fluid sensors and a central server, and a method for real-time monitoring of fluid delivery using machine learning algorithms.

Potential Commercial Applications and Market

The new inventive concept has significant commercial potential in the medical industry, particularly in hospitals and healthcare facilities, for smart fluid management and real-time air bubble detection. The target market includes medical device manufacturers, hospitals, and healthcare providers.
