Detailed Description
The utility model will be described in detail below with reference to the drawings in connection with embodiments.
An extraglottic airway tube, as shown in figures 1 and 2, comprises a tube main body, wherein a tracheal passage 1 and an esophageal passage 2 are arranged in the tube main body side by side, and the positional relationship of the tracheal passage 1 and the esophageal passage 2 accords with the anatomical relationship of human trachea and esophagus.
The tube main body is provided with a throat part blocking air bag 3 corresponding to the position between the tongue root and the epiglottis of the human body, the throat part blocking air bag 3 is preferably circular, or other shapes can be selected, so long as the tube main body can support the position between the tongue root and the epiglottis of the human body after being inflated, and the mouth cavity and the nasal cavity can be blocked at the position. The tube main body is internally provided with a first air charging passage 7 communicated with the throat blocking air bag 3, the first air charging passage 7 is independently externally connected with an air charging tube 5, the air charging tube 5 is provided with an air inlet valve 6, and the esophagus blocking air bag 4 is inflated or deflated through the air charging tube 5.
The lower ends of the tracheal passage 1 and the esophageal passage 2 extend out of the throat part blocking air bag 3 respectively, and the extension length of the esophageal passage 2 is larger than that of the tracheal passage 1, so that the lower port of the esophageal passage 2 is positioned below the lower port of the tracheal passage 1, and the intubation operation is facilitated. The pipe wall of the tracheal passage 1 is provided with an epiglottis supporting part 11 for lifting the human epiglottis after being inserted at the position close to the lower port of the tracheal passage, so as to prevent the phenomenon of unsmooth ventilation of the airway caused by the blockage of the airway by 'epiglottis return fold'. The lower extension end of the pipe wall of the esophagus channel 2 is provided with an esophagus blocking air bag 4 for blocking the esophagus, the esophagus blocking air bag 4 is positioned below the lower port of the tracheal channel 1, a second air charging channel 8 communicated with the esophagus blocking air bag 4 is arranged in the pipe main body, the second air charging channel 8 is independently externally connected with an air charging pipe 5, the air charging pipe 5 is provided with an air inlet valve 6, and the esophagus blocking air bag 4 is inflated or deflated through the corresponding air charging pipe 5.
According to the ventilation catheter, the throat blocking air bag 3 is inserted into the position (the position above the glottis) of the throat of a human body near the throat when the intubation operation is carried out, the oral cavity and the nasal cavity are blocked through the position of the recess between the tongue root and the epiglottis after the inflation, the esophagus blocking air bag 4 is inserted into the esophagus, the esophagus is blocked after the inflation, and the epiglottis supporting part 11 lifts the epiglottis, so that a ventilation passage is established, and smooth ventilation is ensured. The pharyngeal blocking air bag 3 is supported and sealed on the pharyngeal portion (upper position of the glottis) of a human body during intubation, but is not designed to wrap the epiglottis and the glottis, so that the glottis is prevented from being damaged during intubation.
In the utility model, the epiglottis supporting part 11 is provided with a plurality of vent holes 12, the vent holes 12 are communicated with the air pipe channel 1, the epiglottis is abutted against the epiglottis supporting part 11 after the intubation, and the air flowing in the air pipe channel 1 can generate lifting acting force on the epiglottis through the vent holes 12, so that the epiglottis supporting part 11 stably lifts the epiglottis, and the smooth ventilation effect of the air passage is further improved.
