Summary of the Inventive Concept

An improved system for monitoring the life of a physiological sensor, providing real-time sensor life information, self-testing, and calibration adjustments to ensure accurate measurements and extend sensor lifespan.

Background and Problem Solved

The original patent for monitoring the life of a physiological sensor has limitations in accurately tracking sensor usage and detecting degradation. The present inventive concept addresses these limitations by introducing an integrated timer, self-test feature, and calibration adjustments to provide a more reliable and efficient sensor monitoring system.

Detailed Description of the Inventive Concept

The enhanced system comprises a reusable noninvasive physiological sensor with an integrated timer to track usage time. The sensor is connected to a monitor that receives and displays sensor life information. The system also includes a self-test feature to detect sensor degradation and alert the user to replace the sensor. Furthermore, the system calibrates the sensor based on usage time and sensor performance data, ensuring accurate measurements. The inventive concept provides real-time sensor life information, enabling healthcare professionals to make informed decisions about sensor replacement.

Novelty and Inventive Step

The new claims introduce an integrated timer, self-test feature, and calibration adjustments, which are not present in the original patent. These novel features provide a more reliable and efficient sensor monitoring system, enabling accurate measurements and extending sensor lifespan.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include a wireless sensor that transmits usage data to a remote monitor or a cloud-based platform for data analysis and sensor life tracking. Variations of the self-test feature could include automatic sensor calibration or sensor replacement alerts based on usage patterns.

Potential Commercial Applications and Market

The enhanced physiological sensor monitoring system has significant commercial potential in the medical device industry, particularly in critical care and surgical applications where accurate oxygen monitoring is crucial. The system could be marketed to hospitals, clinics, and medical device manufacturers, offering a reliable and efficient solution for physiological sensor monitoring.
