Device for suctioning phlegm in organs for pediatric clinical medicine

The invention discloses a device for suctioning phlegm in organs for pediatric clinical medicine, which comprises a first hose, one end of the first hose is rotationally connected with a second tube, the other end of the first hose is connected with a connector, the other end of the connector is communicated with a negative pressure device, a flexible shaft is arranged on the inner side of the first hose, and one end of the flexible shaft is fixedly connected with a tube body of a second tube. According to the device, the flexible shaft is driven to rotate while the first hose is slowly pulled out, so that the second tube moves in the length direction of the respiratory tract, and meanwhile, the tube opening of the second tube annularly rotates towards the inner wall of the respiratory tract all the time, and therefore all sputum on the inner wall of the respiratory tract is thoroughly cleaned without dead corners; the rotating parts are the flexible shaft in the first hose and the second tube, so that the fi
