Enhanced Respiratory Monitoring System with Multi-Frequency Bioimpedance and Feedback

An advanced respiratory monitoring system that leverages multi-frequency bioimpedance signals and incorporates real-time feedback to improve the accuracy and efficiency of respiratory monitoring, addressing the limitations of existing systems.

The original patent disclosed a system for respiratory monitoring based on bioimpedance signals. However, it had limitations in terms of signal accuracy and the lack of real-time feedback. The present inventive concept addresses these limitations by introducing multi-frequency bioimpedance measurement and incorporating a feedback unit to provide real-time feedback to the subject, enabling more accurate and efficient respiratory monitoring.

The enhanced respiratory monitoring system comprises a bioimpedance measurement sensor configured to acquire bioimpedance signals at multiple frequency bands, a processing unit to receive and process the signals, and a feedback unit to provide real-time feedback to the subject. The system can also incorporate a reference measurement sensor to acquire a reference signal representing the amount of respiratory airflow of the subject. The processing unit determines a respiratory flow signal component based on the bioimpedance signal at each frequency band, and an estimation of the effort signal component based on the acquired bioimpedance signal and the reference signal. The feedback unit provides feedback to the subject based on the determined respiratory flow signal component.

The new inventive concept introduces the use of multi-frequency bioimpedance signals, which enables more accurate and efficient respiratory monitoring. The incorporation of a feedback unit provides real-time feedback to the subject, which is not present in the original patent. These features constitute a novel and non-obvious improvement over the existing system.

Alternative embodiments of the inventive concept may include using different types of sensors, such as electrocardiogram (ECG) or electromyogram (EMG) sensors, to acquire the reference signal. The system may also be adapted for use in different applications, such as in intensive care units or for home-based monitoring.

The enhanced respiratory monitoring system has significant commercial potential in the healthcare industry, particularly in the areas of respiratory care, critical care, and home healthcare. The system's ability to provide accurate and efficient respiratory monitoring, combined with its real-time feedback capabilities, make it an attractive solution for healthcare providers and patients alike.
