Mistaken aspiration prevention early warning system and implementation method thereof

The invention discloses a mistaken aspiration prevention early warning system and an implementation method thereof. The system comprises a PH sensor, a receiver, APP software and an early warning module. The output end of the PH sensor is connected with the input end of the receiver through a sensor circuit. The receiver is connected with the APP software. The output end of the APP software is connected with the input end of the early warning module. The PH sensor is installed on a stomach tube at the lower segment of the esophagus or the outer side wall of a detection guide pipe. The receiver is located outside the body of the patient. Both the APP software and the early warning module are installed on a mobile terminal of a medical worker. Micro esophageal acid reflux at the lower segment of the esophagus is accurately sensed in real time through the PH sensor, alarm signals are triggered by the APP software to activate the early warning module when the PH value is smaller than 4, and the system is more con
