Summary of the Inventive Concept

An enhanced pulse oximetry system that proactively monitors sensor degradation and optimizes sensor performance, ensuring accurate and reliable physiological measurements.

Background and Problem Solved

The original patent, 'System and method for monitoring the life of a physiological sensor,' provides a foundation for pulse oximetry sensor monitoring. However, the existing system has limitations, including the need for manual sensor replacement, sensor signal degradation, and inadequate diagnostic capabilities. The new inventive concept addresses these limitations by introducing advanced sensor monitoring and optimization features.

Detailed Description of the Inventive Concept

The Advanced Pulse Oximetry Sensor Monitoring System comprises a sensor assembly, a monitor, and an optional self-cleaning mechanism. The sensor assembly is configured to detect sensor degradation and transmit a signal to the monitor. The monitor receives the signal and displays a warning indicator when the degradation exceeds a predetermined threshold. Additionally, the system can adjust the sensor's operating parameters to optimize signal quality and reduce degradation. The self-cleaning mechanism can be activated to maintain sensor performance. The system also includes a replaceable optical component that can be swapped out when its optical signal quality degrades below a predetermined level.

Novelty and Inventive Step

The new inventive concept introduces several novel features, including the integration of a self-cleaning mechanism, a replaceable optical component, and a built-in diagnostic module. These advancements provide a significant improvement over the original patent, enabling proactive sensor monitoring, optimization, and maintenance.

Alternative Embodiments and Variations

Alternative embodiments of the Advanced Pulse Oximetry Sensor Monitoring System could include variations in sensor design, such as using different wavelengths or emitter configurations. The system could also be adapted for use with other types of physiological sensors or integrated with other medical devices.

Potential Commercial Applications and Market

The Advanced Pulse Oximetry Sensor Monitoring System has significant commercial potential in the medical device industry, particularly in critical care and surgical applications. The system's ability to ensure accurate and reliable physiological measurements can improve patient outcomes and reduce healthcare costs.
