As shown in fig. 1-4, the utility model provides a sputum suction connector for a tracheal cannula of a newborn, which comprises a connecting pipe 10. The two ends of the connecting pipe 10 are respectively a trachea connecting port 11 and a sputum suction pipe connecting port 12. A breathing tube connector 13 extending outwards is formed in the middle of the connecting tube 10, and the breathing tube connector 13 is communicated with the inside of the connecting tube 10. The connecting pipe 10 is further provided with an isolation valve 14, and the isolation valve 14 is positioned between the breathing pipe connecting port 13 and the sputum suction pipe connecting port 12 and is used for controlling the opening and closing of the connecting pipe 10.

Under the normal working state, the isolation valve 14 is closed, the first end of the air pipe is connected with the air pipe connecting port 11, and the second end of the air pipe extends into the respiratory tract of the newborn; the first end of the breathing tube is connected with a breathing tube connecting port 13, and the second end of the breathing tube is connected with an invasive respirator; the first end of the sputum suction pipe 25 is connected with the sputum suction pipe connecting port 12, the second end of the sputum suction pipe 25 is connected with the negative pressure device, and the respirator helps the neonate to perform normal breathing action at the moment.

When sputum suction operation is needed, medical personnel open the isolation valve 14 first, then slowly push the first end of the sputum suction tube 25 forward, stop feeding the tube after pushing to a proper position, at the moment, the trachea extends deep into the respiratory tract to suck sputum, preferably, the negative pressure suction range of the newborn does not exceed 80mmHg, after 2-3 seconds of sputum suction, the sputum suction tube 25 is slowly pulled back while sucking, repeated operation can be carried out when the sputum is thick, and then the isolation valve 14 is closed. In the whole sputum suction operation process, the trachea does not need to be separated from the breathing machine, so that the trachea can not be separated.

In one embodiment, a sealing assembly 20 is also included, which is disposed at the suction tube connection port 12. The seal assembly 20 includes a rotating ring 21, an annular stop 22 and a sealing ring 23. The rotating ring 21 is arranged outside the sputum suction pipe connecting port 12 and is rotatably connected with the side plates 15 on both sides of the connecting pipe 10 through a bearing 24, specifically, the outer ring of the bearing 24 is fixedly connected with the side plates 15, the inner ring of the bearing 24 is rotatably connected with the rotating ring 21, and the inner wall of the rotating ring 21 is provided with an internal thread 211.

The first end of the sputum-aspirating tube 25 passes through the rotating ring 21 and then extends into the connecting tube 10 from the sputum-aspirating tube connecting port 12, and the outer peripheral surface of the first end of the sputum-aspirating tube 25 is provided with an external thread 251 which can be matched with the internal thread 211. The annular blocking portion 22 is fixedly installed at a first end of the sputum aspirator tube 25 for preventing the sputum aspirator tube 25 from being separated from the connection tube 10. The sealing ring 23 is fixedly arranged on the inner wall of the sputum suction pipe connecting port 12 and can be contacted with the annular blocking part 22. The connecting pipe 10 is further provided with a water inlet 16 extending outwards, the water inlet 16 is positioned between the isolating valve 14 and the sputum suction pipe connecting port 12 and is communicated with the inside of the connecting pipe 10, and the water inlet 16 is provided with a cap 17.

In order to prevent the sputum from being blocked due to bacterial fixed planting and sputum scabbing, the inside of the sputum suction pipe 25 needs to be washed after the sputum suction operation is finished every time. The specific steps of the washing are as follows: first, the medical staff disconnects the second end of the sputum aspirator tube 25 from the negative pressure device and puts it into the sink. Then one hand of the medical staff pulls the sputum suction tube 25 outwards, when the external thread 251 of the sputum suction tube 25 contacts the rotating ring 21, the other hand rotates the rotating ring 21, and the sputum suction tube 25 is gradually pulled outwards under the action of thread matching until extrusion is formed between the annular blocking part 22 and the sealing ring 23; due to the threaded fit between the sputum aspirator tube 25 and the rotating ring 21, the pressing between the annular blocking portion 22 and the sealing ring 23 can improve the sealing effect between the sputum aspirator tube connecting port 12 and the sputum aspirator tube 25. Then the cover cap 17 is opened, water is injected into the water inlet 16 of the needle tube or other water injection equipment box, under the action of the sealing assembly 20, the injected water enters from the first end of the sputum suction tube 25, passes through the sputum suction tube 25 and then flows into the water tank from the second end, and the flushing is completed. The cleaning steps are simple and convenient to operate.

In one embodiment, the annular stopper 22 is formed with an inclined annular guide surface 221 on its outer circumferential surface. When the annular stopper 22 contacts the seal ring 23, the annular guide surface 221 causes the seal ring 23 to tend to approach the inner wall of the suction tube connection port 12. When the sputum suction tube 25 is pulled outwards, the annular blocking part 22 is gradually close to the sealing ring 23, and the sealing ring 23 is gradually close to the inner wall of the sputum suction tube connecting port 12 under the action of the annular guide surface 221, so that the sealing performance between the sputum suction tube connecting port 12 and the sputum suction tube 25 is further improved.

In one embodiment, a handle 26 is mounted on the rotating ring 21, and the handle 26 can facilitate the medical staff to control the rotation of the rotating ring 21.

In one embodiment, the outer peripheral surfaces of the tracheal connection port 11 and the respiratory tube connection port 13 are each provided with an inwardly extending annular groove 18, and each annular groove 18 is provided with a rubber ring 30. Under the normal operating condition, rubber ring 30 is in the state of being expanded to can further improve the leakproofness between trachea connector 11 and the trachea, between respiratory tube connector 13 and the respiratory tube.
