[0041] The three-way pipe 1 is internally provided with three air ducts 101 which are interconnected.

[0042] One end of each of the three corrugated pipes 2 is sealingly fixed in the three air ducts 101, and the corrugated pipe 2 is a flexible connecting pipe which has the characteristics of being stretchable and bendable.

[0043] The gas cutting inner pipe 3 is used for being inserted and fixed in a gas cutting outer pipe which is fixed in the trachea of a patient, one end of the gas cutting inner pipe 3 is sealingly fixed at the end of one of the corrugated pipes 2 which is away from the three-way pipe 1, so that the trachea of the patient is connected with one of the air ducts 101 in the three-way pipe 1; as shown in Figure 1 Since the gas cutting inner pipe 3 is connected with the three-way pipe 1 through the corrugated pipe 2, the positions of the gas cutting inner pipe 3 and the three-way pipe 1 can be changed, so that the connection and adhesion of the gas cutting inner pipe 3 and the three-way pipe 1 are not affected when the patient changes the body position, and the sealing performance of the oxygen pipeline is improved.

[0044] The check valve 4 is used for controlling the airflow to flow in one direction only, and the two check valves 4 are fixedly arranged in the two air ducts 101 which are connected with the other two corrugated pipes 2, and the installation directions of the two check valves 4 are opposite, that is, the two check valves 4 are fixedly arranged in the two air ducts 101 which are not directly connected with the gas cutting inner pipe 3; as shown in Figure 6As shown, the left airway 101 is in communication with the tracheostomy tube 3, the upper right airway 101 and the lower right airway 101 are both provided with one-way valves 4 and are in communication with the exhaust device and the oxygen supply device respectively, and the directions of the two one-way valves 4 are opposite. When the patient inhales, oxygen enters the patient's trachea from the oxygen supply device through the corrugated tube 2 connected with the lower right airway 101, the lower right airway 101, the one-way valve 4 in the lower right airway 101, the corrugated tube 2 connected with the left airway 101 and the tracheostomy tube 3. When the patient exhales, the gas is discharged into the exhaust device through the tracheostomy tube 3, the corrugated tube 2 connected with the left airway 101, the one-way valve 4 in the upper right airway 101, the upper right airway 101 and the corrugated tube 2 connected with the upper right airway 101, thereby ensuring the breathing needs of the patient and avoiding the mixing of the two gases. The one-way principle and structure of the one-way valve 4 are prior art.

The sealing sleeve 53 is sealingly fixed in the pipe body 51 away from the corrugated tube 2, and one end of the tracheostomy tube 3 is sealingly fixed in the sealing sleeve 53. The sealing sleeve 53 is made of flexible rubber material. After the end of the tracheostomy tube 3 is inserted into the sealing sleeve 53, the one end of the opening and closing groove 501 of the pipe body 51 is contracted by locking the throat clamp 52, thereby improving the connection sealing and firmness of the sealing sleeve 53 and the tracheostomy tube 3. In addition, when the outer diameter of the end of the tracheostomy tube 3 is slightly smaller than the inner diameter of the sealing sleeve 53, the tracheostomy tube 3 and the sealing sleeve 53 can be sealingly connected by locking the throat clamp 52, thereby further improving the adaptability of the adapter pipe 5.

When the air cutting inner pipe 3 is inserted into the sealing sleeve 53, the abutting of the end of the sealing sleeve 53 and the top groove 503 can avoid the axial movement of the sealing sleeve 53, thereby improving the connection convenience of the air cutting inner pipe 3.

[0051] As shown, Figure 3 and Figure 4 The opening and closing groove 501 is arranged in multiple, and the multiple opening and closing grooves 501 are arranged in the circumferential array around the center line of the pipe body 51, thereby improving the contraction efficiency and contraction stability of the end of the pipe body 51.

[0052] As shown, Figure 2 and Figure 7 The outer side of the end of the air cutting inner pipe 3 is provided with a ring groove 301, and the sealing sleeve 53 is deformed by extrusion when the end of the pipe body 51 is contracted, so that the sealing sleeve 53 fills the ring groove 301, thereby improving the fixing firmness of the air cutting inner pipe 3 and the sealing sleeve 53.

[0053] As shown, Figure 1 The tee pipe 1 is preferably a Y-shaped tee pipe, which is convenient for connecting one end of the tee pipe 1 with the air cutting inner pipe 3, and the other end with the oxygen supply equipment and the exhaust equipment.
