Non-contact neonatal respiration monitoring system and device and storage medium

Abstract

The invention discloses a non-contact neonatal respiration monitoring system and device and a storage medium. The system comprises a signal acquisition module, wherein respiration and heartbeat signals of a plurality of objects are collected in real time based on the MIMO-FMCW radar; a feature extraction module which performs signal processing on the breathing and heartbeat signals, and extracts characteristic parameters reflecting breathing conditions and heartbeat conditions; an abnormal information identification module which judges whether abnormal information exists or not based on the combination of one or more feature parameters and mapping of the feature parameter numerical range corresponding to the abnormal information, and determines specific abnormal information; an abnormal information processing module which selects information feedback and / or alarm according to the abnormal information type. Based on the 24 GHz MIMO-FMCW system, the breathing condition of the neonates is monitored in real time by extracting instantaneous indexes of breathing and heartbeat signals of the neonates, the breathing abnormity evaluation and alarm functions can be provided, and the system is effective, feasible and reliable in performance.

Description

technical field [0001] The invention relates to the field of vital sign monitoring, in particular to a non-contact neonatal respiratory monitoring system, equipment and storage medium. Background technique [0002] About 16 million newborns are born in China every year, of which about 2 million are premature. Due to the immature development of body organs, premature infants are prone to abnormal breathing, mainly manifested as apnea, which is a relatively serious complication with a high incidence rate, manifested as respiratory arrest for more than 20 seconds, or respiratory arrest Less than 20s but accompanied by bradycardia, hypoxemia, etc. If it is not treated in time, it will cause damage to the central nervous system due to hypoxia, and even cause respiratory and circulatory failure and death in severe cases. [0003] Real-time monitoring of neonatal respiratory status is very important. At present, the main methods include thermal method, pressure method, chest impe...

AI Technical Summary

Problems solved by technology

Among them, the heat-sensitive method and the pressure method monitor the breathing through the temperature and air pressure changes at the mouth and nose when the patient breathes, but need to wear equipment such as a gas mask; the chest impedance method obtains real-time breathing by sticking electrodes on the chest, but the skin of the newborn is extremely fragile , the contact method is very easy to cause damage to newborns; while the operation of ultrasound and X-ray inspection is relatively cumbersome, and real-time monitoring cannot be achieved
