[0018] See also Figures 1 to 8 As shown, a tracheal cannula and ventilator connecting device comprises a reducing connecting pipe 1, a connecting seat 2 and a fixing belt 3, wherein the reducing connecting pipe 1 is detachably connected to the connecting seat 2, and both ends of the fixing belt 3 are detachably connected to both sides of the connecting seat 2, and one end of the reducing connecting pipe 1 is a ventilator tracheal connecting pipe 11 and the other end is a tracheal cannula connecting pipe 12;

[0019] Specifically, the diameter of the ventilator tracheal connecting tube 11 matches the ventilator trachea, the diameter of the tracheal cannula connecting tube 12 matches the diameter of the tracheal cannula, the ventilator tracheal connecting tube 11 can be inserted into the ventilator trachea, the tracheal cannula connecting tube 12 is sleeved on the outside of the tracheal cannula, the connecting seat 2 is used to install the reducing connecting tube 1, and the fixing belt 3 is used to fix the entire device at the patient's neck. The device connects the ventilator trachea with the tracheal cannula through the ventilator tracheal connecting tube 11 on the reducing connecting tube 1 and the tracheal cannula connecting tube 12;

[0020] The outer wall of the ventilator trachea connecting tube 11 is evenly provided with first annular protrusions 111, and the inner wall of the tracheal tube connecting tube 12 is evenly provided with second annular protrusions 121;

[0021] Specifically, the first annular protrusion 111 on the outer wall of the ventilator trachea connecting tube 11 is used to increase the stability of the connection between the reducing connecting tube 1 and the ventilator trachea and the air-guiding sealing performance, and the second annular protrusion 121 on the inner wall of the tracheal tube connecting tube 12 is used to increase the stability of the connection between the reducing connecting tube 1 and the tracheal tube and the air-guiding sealing performance;

[0022] The reducing connecting pipe 1 is symmetrically provided with a limit block 13, the connecting seat 2 is provided with an annular slide groove 22, and the annular slide groove 22 is symmetrically provided with a mounting groove 23, the size of the mounting groove 23 matches the limit block 13, and the limit block 13 can slide in the annular slide groove 22;

[0023] Specifically, the limit block 13 on the reducer connecting tube 1 can be installed in the annular slide groove 22 through the installation groove 23, and the limit block 13 can slide in the annular slide groove 22, so that the connecting seat 2 can not only axially position the reducer connecting tube 1, but also rotate on the connecting seat 2, so that the reducer connecting tube 1 is convenient to connect with the ventilator trachea and tracheal cannula;
