Abstract
A neonatal apnea rescue device is to collect blood oxygen signals of the newborn through a blood oxygen monitoring module, and obtain the blood oxygen saturation according to the blood oxygen signals. At the same time, the device adopts a respiratory monitoring module to collect the newborn's respiration signal according to which the rate of respiration is acquired. A main control module receives the newborn's blood oxygen signals, blood oxygen saturation, respiratory signal and rate of respiration, and identifies whether the received blood oxygen saturation or the rate of respiration is beyond the scope of threshold value or not. If the scope of threshold value is exceeded, the main control module is to control a lapping and stimulating module to lap the foot sole of the newborn or control a thermal stimulation module to perform thermal stimulation on the foot sole of the newborn, so as to enable the newborn to restore spontaneous breathing. The rescue process is monitored automatically by the neonatal apnea rescue device, and the control signal of the main control module is implemented; and the whole process requires no human intervention.
