Summary of the Inventive Concept
An advanced fluid sensor system that integrates a non-invasive ultrasonic transmitter, a pressure sensor, and a temperature sensor to provide real-time monitoring of fluid properties, enabling accurate detection of air bubbles, occlusions, and other anomalies in fluid delivery conduits.
Background and Problem Solved
The original fluid sensor patent, while effective in certain applications, has limitations in accurately detecting fluid properties, particularly in the presence of air bubbles or occlusions. The new inventive concept addresses these limitations by incorporating a temperature sensor and advanced signal processing, enabling real-time monitoring of fluid properties and ensuring safer, more efficient fluid delivery.
Detailed Description of the Inventive Concept
The enhanced fluid sensor system comprises a compact, low-power ultrasonic transmitter that emits signals through the fluid delivery conduit, a pressure sensor that detects pressure changes, and a temperature sensor that detects temperature changes within the conduit. The system further includes a microcontroller that processes the pressure sensor output signal and generates an alert signal in response to detecting an occlusion or air bubble. The system can be integrated with a pump and a controller, featuring a user interface that displays real-time fluid properties and alerts the user to potential issues.
Novelty and Inventive Step
The new inventive concept introduces a temperature sensor to detect temperature changes, enabling accurate monitoring of fluid properties. Additionally, the system's advanced signal processing and microcontroller-based alert generation provide a non-obvious solution to the limitations of the original patent.
Alternative Embodiments and Variations
Alternative embodiments of the inventive concept could include the use of different types of sensors, such as optical or acoustic sensors, or the integration of machine learning algorithms to improve the accuracy of fluid property detection. Variations of the system could be designed for specific industries, such as medical or industrial applications.
Potential Commercial Applications and Market
The enhanced fluid sensor system has significant commercial potential in the medical and industrial industries, where accurate fluid property monitoring is critical. The system could be integrated into infusion pumps, dialysis machines, and other medical devices, as well as industrial processes, such as chemical processing and oil refining.
