The signal transmission line 3 is provided with scale marks so that medical staff can master the moving distance of the signal transmission line 3.
The specific implementation process is as follows: when the laryngeal mask is inserted into the tube, medical staff pull the signal transmission line 3, so that the pH sensor probe 4 on the signal transmission line 3 retracts into the flow channel I101, and the influence of the pH sensor probe 4 on the insertion tube of the laryngeal mask is avoided. After the laryngeal mask intubation is completed, the medical staff pushes the signal transmission line 3, so that the signal transmission line 3 advances along the flow channel II 201 and the flow channel I101, and the pH sensor probe 4 extends out of the flow channel I101 and enters the esophagus of a patient. In the process, medical staff can control the pH sensor probe 4 to enter the esophagus of the patient by 1-2cm through the scale marks on the signal transmission line 3, so that the depth of the pH sensor probe 4 entering the esophagus of the patient is prevented from being too deep.
Then, when gastric juice refluxes to the patient esophagus in-time, pH value mutation is monitored to pH sensor probe 4 to transmit this mutation signal to controller 5 through signal transmission line 3, controller 5 control alarm sends out the police dispatch newspaper, warns medical personnel patient and takes place the gastric juice reflux, so that medical personnel in time carry out the gastric juice suction measure, avoid gastric juice reflux to the trachea of patient in, thereby avoid patient's trachea and lung impaired.
Example two
