Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of lung detectors, and in particular to an intelligent lung function detector with multi-modal sensor fusion. Background Art
[0002] At the detection function level, current traditional pulmonary function testing technology mostly relies on a single or a few sensors for detection.
[0003] For example, common simple pulmonary function testers are only equipped with simple flow sensors and can only measure a single indicator, namely respiratory flow. They are unable to monitor key parameters such as exhaled gas composition and respiratory pressure, and it is difficult to fully reflect the ventilation and gas exchange functions of the lungs. Even some more complex traditional equipment simply combines different types of sensors, and each sensor works independently and lacks coordination. For example, traditional testers used in some hospitals have flow sensors and gas detection sensors that operate independently and are unable to comprehensively analyze data, resulting in deviations in the assessment of lung gas exchange efficiency, making it difficult to accurately judge the health of the lungs.
[0004] At the same time, traditional equipment generally lacks the ability to detect blood oxygen content, which is an important indicator of the lung's oxygen uptake and delivery capacity. The lack of this key data further limits the comprehensive assessment of lung function, leaving much room for improvement in the comprehensiveness and accuracy of testing. Summary of the invention
