The conversion joint 2 is used to conduct the first channel 3 and the gas inhalation pipe, and the outer side wall of the conversion joint 2 can be in sealed contact with the inner side wall of the first channel 3. Preferably, the conversion joint 2 achieves sealed contact with the inner side wall of the first channel 3 through elastic deformation. In this way, the first channel 3 can not only be directly connected to the gas inhalation pipe, but also the first channel 3 and the gas inhalation pipe can be connected through the conversion joint 2; the number of conversion joints 2 is at least two, and the sizes of each conversion joint 2 are respectively adapted to different specifications of gas inhalation pipes, that is, the sizes of the gas through holes in each conversion joint 2 can be respectively adapted to different specifications of gas inhalation pipes; in this way, the side wall of the gas through hole in the conversion joint 2 can be sleeved on the outside of the corresponding specification of the gas inhalation pipe. The conversion joint 2 is arranged on the outer side wall of the three-way pipe 1 through a joint support. The joint support specifically includes a base, the base is arranged on the side wall of the three-way pipe 1, and any one conversion joint 2 is arranged on the base. Through the joint support, the conversion joint 2 can be effectively supported.

[0038] Working principle: According to the different ages of patients, the specifications of the gas inhalation tubes configured on the patients are also different. A variety of conversion joints 2 are arranged on the tee 1 through joint supports. The tee 1, the joint support, and the conversion joint 2 are of an integral structure. Select a conversion joint 2 that matches a specific gas inhalation tube. The size of the gas through-hole of the selected conversion joint 2 matches the outer diameter of the gas inhalation tube, so that the conversion joint 2 can be tightly sleeved on the outer side wall of the gas inhalation tube through the gas through-hole. During specific operation, place the specific conversion joint 2 into the first channel 3 of the tee 1. Preferably, the outer side wall of the conversion joint 2 can be in sealing contact with the inner side wall of the first channel 3. Then, place the corresponding gas inhalation tube into the gas through-hole of the conversion joint 2, so that the outer side wall of the gas inhalation tube can be in sealing contact with the side wall of the gas through-hole of the conversion joint 2. Thus, the first channel 3 can be connected to different specifications of gas inhalation tubes through the conversion joint 2.

When the conversion joint 2 does not need to be connected to the first channel 3, the conversion joint 2 can be supported by the elastic arm 6. When it is necessary to connect the conversion joint 2 to the first channel 3, the operator controls the movement of the specific conversion joint 2 to cause the elastic arm 6 to undergo elastic deformation until the conversion joint 2 is placed into the first channel 3 to connect the conversion joint 2 to the first channel 3. After the operator removes the conversion joint 2 from the first channel 3, the elastic arm 6 can recover its deformation and effectively support the conversion joint 2.

[0047] S2, as Figure 7As shown, the third channel 5 is communicated with the atomizing device 16, the second channel 4 is connected to the gas delivery pipe, the first joint 11 is inserted into the first channel 3, the first joint 11 is connected to the first channel 3, the outer side wall of the first joint 11 is in sealing abutment with the inner side wall of the first channel 3, the second joint 12 is inserted into the gas through hole of the first joint 11, and the outer side wall of the second joint 12 is in sealing abutment with the side wall of the gas through hole of the first joint 11; the first inhalation tube 17 is inserted into the gas through hole of the second joint 12, the second joint 12 is sleeved with the first inhalation tube 17, and the side wall of the gas through hole of the second joint 12 is in sealing abutment with the outer side wall of the first inhalation tube 17; at this time, the first inhalation tube 17 is communicated with both the atomizing device 16 and the gas delivery pipe at the same time, realizing the sharing of the atomizing device 16, the ventilator and the 10mm standard breathing tube, and synchronous ventilation and atomization treatment.

[0049] Preferably, the gas delivery pipe communicated with the second channel 4 is a 22mm standard gas delivery pipe.

[0050] Further, the gas through hole in the first joint 11 can be named the first intermediate channel 14, the gas through hole in the second joint 12 can be named the second intermediate channel 15, and the aperture of the first intermediate channel 14 is larger than that of the second intermediate channel 15; the first joint 11 can be inserted into the first channel 3, the second joint 12 can be inserted into the first intermediate channel 14, at this time the second intermediate channel 15 is communicated with the first channel 3, the first inhalation tube 17 is inserted into the second intermediate channel 15 to make the first inhalation tube 17 communicated with the first channel 3. The third inhalation tube 19 is adapted to adults, the second inhalation tube 18 is adapted to children, and the first inhalation tube 17 is adapted to neonates.

[0051] In one embodiment, the structure of the second joint 12 can also be changed. The gas through hole in the second joint 12 can be matched with the first inhalation tube 17, and the outer side wall of the second joint 12 can directly abut against the inner side wall of the first channel 3. Thus, without passing through the first joint 11, the second joint 12 can be directly inserted into the first channel 3. At this time, the outer side wall of the second joint 12 is in sealing abutment with the inner side wall of the first channel 3. Then, the corresponding gas inhalation tube is inserted into the gas through hole in the second joint 12. This gas inhalation tube is preferably the first inhalation tube 17, and the outer side wall of the gas inhalation tube is in sealing abutment with the inner side wall of the second joint 12.

[0052] In one embodiment, any one of the adapters 2 is composed of a rubber plug, and the gas through-hole can penetrate the rubber plug. Due to the good flexibility of the rubber plug, it can undergo good elastic deformation. When the rubber plug is inserted into the tee 1, the rubber plug is squeezed, causing a certain degree of elastic deformation of the rubber plug. The outer sidewall of the rubber plug can be stably sealed and abutted against the inner sidewall of the tee 1. When the corresponding gas inhalation pipeline is inserted into the gas through-hole in the rubber plug, the rubber plug is further squeezed, and the rubber plug further undergoes elastic deformation. The outer sidewall of the gas inhalation pipe can be stably sealed and abutted against the inner sidewall of the rubber plug, solving the problem of air leakage during ventilation.

[0053] In one embodiment, it further includes a sealing plug 13. The sealing plug 13 is also fixedly connected to the base through the elastic arm 6. When the base is the ferrule 9, the elastic arm 6 on the sealing plug 13 is also integrally formed with the ferrule 9. The outer diameter of the sealing plug 13 is adapted to the diameter of the third channel 5, and the sealing plug 13 is used to be sealed and abutted against the third channel 5. When nebulization treatment is not required, the nebulization output pipe is pulled out from the third channel 5, and the sealing plug 13 is inserted into the third channel 5. The sealing plug 13 is composed of a rubber plug and has a certain elasticity. The outer sidewall of the sealing plug 13 is sealed and abutted against the inner sidewall of the third channel 5.

[0054] After the nebulization treatment, by inserting the sealing plug 13 into the third channel 5, the sealing plug 13 can seal the third channel 5 without removing the tee 1; when nebulization treatment is performed again, the sealing plug 13 is pulled out to reconnect the third channel 5 to the nebulization device 16, and then nebulization treatment can be carried out, which is simple and convenient.

[0055] In one embodiment, the first channel 3 and the second channel 4 are coaxially connected and axially aligned, so that the first channel 3 and the second channel 4 form a continuous air pipeline, ensuring the continuity and stability of air flow delivery. The third channel 5 is connected to both the first channel 3 and the second channel 4 at the same time; the third channel 5 is inclined; preferably, the axis of the third channel 5 is the third axis, the axis of the first channel 3 is the first axis, and the included angle between the third axis and the first axis is an acute angle. The direction of delivering the nebulized drug in the third channel 5 is the nebulized drug delivery direction, and the direction of delivering gas in the first channel 3 is the gas delivery direction. The horizontal component of the nebulized drug delivery direction coincides with the gas delivery direction and has the same orientation. In this way, the drug delivery direction can be output along the gas delivery direction, which is more conducive to ensuring the stability of the air flow. Of course, the position of the third channel 5 can be adjusted according to the actual situation, and the included angle between the third axis and the first axis can also be set as an obtuse angle or a right angle to appropriately change the mixing degree of the drug and the air flow.
