Non-contact neonatal respiratory monitoring system, equipment and storage medium

Abstract

The invention discloses a non-contact neonatal breathing monitoring system, equipment and a storage medium. The system includes a signal acquisition module; real-time acquisition of breathing and heartbeat signals of multiple objects based on MIMO-FMCW radar; a feature extraction module; Carry out signal processing with the heartbeat signal, extract characteristic parameters that reflect the breathing condition and heartbeat condition; abnormal information identification module; determine whether there is abnormal information based on the combination of one or more characteristic parameters and the mapping of the value range of the characteristic parameter corresponding to the abnormal information, and clarify Specific abnormal information; abnormal information processing module; select information feedback and / or alarm according to the type of abnormal information. Based on the 24GHz MIMO-FMCW system, the present invention monitors the breathing condition of the newborn in real time by extracting the instantaneous indicators of the breathing and heartbeat signals of the newborn, and can provide abnormal breathing evaluation and alarm functions, which are effective, feasible, and reliable.

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] There are about 16 million babies born in China every year, of which about 2 million are premature babies. Premature infants are prone to abnormal breathing due to the incomplete development of body organs, mainly manifested as apnea, which is a relatively serious complication with a high incidence rate, manifested as respiratory arrest for more than 20s, or respiratory arrest. Less than 20s but accompanied by bradycardia and hypoxemia. If it is not treated in time, it will cause damage to the central nervous system due to hypoxia, and even lead to 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, thor...

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
