The present invention discloses a stomach tube for preventing aspiration, comprising: a control circuit, an air pump, a PH sensor and a stomach tube provided with an air sack, wherein the air pump is in communication with the air sack, the PH sensor is arranged on an inner wall of the stomach tube at a distance of 40cm away from a foretooth, and the control circuit is connected to the air pump and the PH sensor, respectively. The stomach tube of the present invention uses the PH sensor and the pressure sensor to monitor the PH value of the esophagus and the pressure of the air sack in real time, so as to accurately detect the occurrence of stomach esophagus regurgitation each time in advance, thereby avoiding the possibility of aspiration caused by regurgitation and the recessive pneumonia caused thereby; meanwhile, the present invention adopts a real-time control manner to automatically start the expansion of the air sack, thereby avoiding the damage to the esophageal mucosa caused by the long-time compression of the air sack on the esophagus, and reducing the substernal discomfort of a user. As a stomach tube for preventing aspiration, the present invention can be widely applied to the field of medical instruments. |
