The invention discloses an automatically-controlled double-balloon cannula tracheostomy tube. The key point of the technical scheme adopted by the invention is as follows: the automatically-controlled double-balloon cannula tracheostomy tube comprises a double-balloon cannula tracheostomy tube; air filling tubes used for filling balloons with air are arranged on the double-balloon cannula tracheostomy tube; the double-balloon cannula tracheostomy tube is connected with an electric control box used for controlling air filling and air discharging of the balloons; the electric control box comprises air filling openings connected with the air filling tubes, an air filling device used for filling air into the balloons, a switch assembly used for controlling operation of the air filling device and a monitoring device used for monitoring pressure state of the balloons. The automatically-controlled double-balloon cannula tracheostomy tube is capable of automatically controlling air filling and air discharging of the balloons and alternately using the balloons; the stability of the balloons in the using process can be improved; the case of the burst of the balloons is avoided; the structural stability of the double-balloon cannula tracheostomy tube is improved; the case of the scratch is avoided.
