Located between the first and second sections as a connecting pipe.

Specifically, when the user inhales, the atomized gas in the atomization chamber can be sent into the third opening 13 under the action of the user's suction or pumping, and enters the trachea from the user's tracheal incision; when the user exhales When the person exhales, the gas exhaled by the person leaves from the third opening 13 and the fourth opening 14; at the same time, when the medicine enters the atomization chamber, the oxygen and the atomized medicine can be mixed in the atomization chamber without leakage.

Referring to the atomization joint shown in Figures 1 and 2, the atomization chamber is a hose, formed between the second opening 12 and the third opening 13 of the delivery pipe 1, and has the function of enabling the first opening 11 to be in a closed state. The preset length can be greater than the distance between the first opening 11 and the second opening 12, or the preset length can be designed according to actual needs. For example, if the medicine entering through the third opening 13 is already in an atomized state, the atomization chamber does not need to be too long to allow oxygen to be mixed with the atomized medicine. At the same time, the length of the atomizer allows a certain safe distance between the air inlet end and the air outlet end to prevent the gas containing the medicine in the atomization chamber from being directly discharged from the fourth opening 14 . Preferably, the first opening 11 is provided at the end of the first end of the delivery pipe 1, and the opening direction of the first opening 11 is parallel to the axis direction, which facilitates processing and molding. At the same time, the axis is linear. The design also makes the check valve easier to install and operate.

Preferably, the fourth opening 14 is provided at the end of the second end of the delivery pipe 1 , and the opening direction of the fourth opening 14 is parallel to the axis direction, which is the same as the design of the first opening 11 . Specifically, as shown in Figures 2 and 3, the second opening 12 has a lower connecting section 121 and an upper connecting section 122. The lower connecting section 121 is used to connect with the first opening 11 to form a first end, and the upper connecting section 122 Connected to the atomization chamber. As shown in Figure 2, the diameter of the lower connecting section 121 and the upper connecting section 122 is smaller than the diameter of the conveying pipe 1, so that the second opening 12 can be inserted into the conveying pipe and forms a part of the conveying pipe 1. At the same time, the second opening 12 is in It can be rotated when it matches the diameter of the delivery pipe 1, so that the orientation of the second opening 12 can be adjusted during use.

Preferably, an oxygen small tube 123 connected in parallel with the first one-way valve 2 can also be provided upstream of the first opening 11 . Thus, air can enter from the first one-way valve 2 as a whole, and oxygen can also be input from the oxygen small tube 123 , to adapt to grid atomizers, ultrasonic atomizers, mesh atomizers, etc., thus matching all atomizer types.

Preferably, the second opening 12 and the third opening 13 are provided on the side wall of the delivery pipe 1, which can avoid obstacles in use caused by the openings being provided on the same side.

Furthermore, the second opening 12 and the third opening 13 are provided on opposite sides of the delivery tube 1 , which can avoid installation and use obstacles caused by excessive connecting tubes on the same side as the tracheal incision.

Preferably, the second opening 12 is disposed adjacent to the first opening 11 so that oxygen and aerosolized medicine can be premixed to avoid a single concentration of gas being too high and causing a stress reaction in the user, and the second opening 12 Continuous supply of medication.

Preferably, the fourth opening 14 is disposed adjacent to the third opening 13 so that the user's exhaled gas can be discharged from the fourth opening 14 .

Preferably, as shown in FIG. 2 , the second opening 12 is arranged at an angle, and the free end of the second opening 12 is directed from the first end of the delivery pipe 1 toward the delivery pipe 1 compared to its connecting end. The second end direction gradually approaches the delivery pipe 1, reducing the lateral extension space of the atomization joint, making it easier for the operator to hold the atomization joint for care and installation. In addition, when the direction of the second opening 12 is close to the direction of the first opening 11, It can make the flow direction of drug feeding and oxygen flow tend to be consistent, thereby making the atomization mixing effect better and more complete.

Preferably, the delivery pipe 1 includes a first joint, an atomization tube detachably connected to the first joint, and a second joint detachably connected to the atomization tube, wherein the third joint is detachably connected to the atomization tube. An opening 11 and the second opening 12 are formed on the first joint, the third opening 13 and the fourth opening 14 are formed on the second joint, and the atomization chamber is formed on the on the atomizer tube.

In Figure 4, the hollow arrow shows the flow direction of the gas in the delivery tube 1 of the atomizing joint when the user inhales. Specifically, when inhaling, the first one-way valve is opened under the action of suction, the second one-way valve is closed under the action of gas flow, and the oxygen in the first opening 11 is opened under the action of suction of the user's trachea. It enters the delivery tube 1 and mixes with the medicinal mist at the second downstream opening 12, flows toward the third opening 13, and enters the user's trachea through the third opening 13.

In Figure 5, the hollow arrow shows the direction of gas flow within the atomizing joint when the user exhales. Specifically, when exhaling, the first one-way valve 2 is closed, the second one-way valve 3 is opened under the flow of exhaled gas, and the user's exhaled gas is output from the third opening 13. Since, the third one-way valve 3 is opened. When a one-way valve 2 is closed, the gas located at the air inlet end of the delivery pipe 1 cannot flow, and the third opening 13 is far away from the air inlet end (abbreviation for the first opening 11 and the second opening 12), so the air inlet end is far from the air inlet end. The air pressure between the three openings 13 is large, and the third opening 13 and the fourth opening 14 are close to each other. The air pressure between the third opening 13 and the fourth opening 14 is small. It is difficult for the gas in the low pressure area to move to the high pressure area. Therefore, the exhaled gas is discharged from the fourth opening 14 preferentially under the thrust of the flow force. The airflow force output by the third opening 13 during exhalation can be divided into two parts. One part is the airflow force that resists the atomization chamber; the other part is the exhaust force that opens the fourth opening 14.

Preferably, the first one-way valve 2 and the second one-way valve 3 are one-way movable flaps, which control air inlet and outlet according to the directions indicated by the hollow arrows shown in Figures 1 and 2. The one-way valve is preferably a membrane structure.
