The invention relates to the technical field of
medical instruments, and discloses a
lung rehabilitation breathing exercise device which comprises a
breathing exercise module, a monitoring module, an adjusting module, a central
processing and control module and an abnormity monitoring and
processing module. The monitoring module collects a multi-
modal physiological
signal of a patient in real time. The central
processing and control module processes the signals, calculates a
respiratory effort index reflecting the real-time respiratory state of a patient, and dynamically controls the adjusting module to change the resistance of a respiratory channel by comparing the index with the deviation of the target
training intensity, so that the personalized self-adaptive adjustment of the
training intensity is realized. Meanwhile, the abnormity monitoring and processing module calculates the risk coefficient of the equipment by analyzing the state data of the equipment, thereby achieving the real-time monitoring and grading early warning of the equipment. The problems that an existing
breathing exerciser cannot dynamically adjust training parameters according to the real-time physiological state of a patient and lacks intelligent abnormity monitoring are solved, and the safety and accuracy of
lung rehabilitation training and the equipment reliability are improved.
