The sliding frame 302 is slidably mounted on one side of the fixed frame 304, so that the sliding frame 302 can slide vertically up and down along the fixed frame 304. The sliding frame 302 and the fixed frame 304 are fixedly connected. A tension spring 303 is fixedly connected between the racks 304, and a tension effect can be generated by the tension spring 303, which can provide a force for the sliding rack 302 to move upward. A bracket 301 is fixedly connected to one side of the sliding rack 302, and a docking port 105 is fixedly installed at the bottom of the sampling tube 1. A reagent bottle 2 is fixed between the docking port 105 and the bracket 301. A limiting groove is provided on the bracket 301, which can limit the bottom of the reagent bottle 2. By placing the reagent bottle 2 in the bracket 301, the bracket is driven The bracket 301 moves downward, so that the bottle mouth of the reagent bottle 2 can correspond to the docking port 105 above. The tension of the tension spring 303 can drive the bracket 301 to move upward, so that the bottle mouth of the reagent bottle 2 can be inserted into the docking port 105, so that the sampling cylinder 1 can be connected with the reagent bottle 2, which can facilitate the installation and removal of the reagent bottle 2. The piston rod 101 is slidably installed inside the sampling cylinder 1, and one end of the piston rod 101 extends out of the sampling cylinder 1. One side of the sampling cylinder 1 is connected to the hose 103. A suction head 104 is provided, and a handle 102 is fixedly installed at the bottom of the sampling tube 1. By using the handle 102, the device can be conveniently held. By placing the suction head 104 into the patient's mouth and pulling the piston rod 101, sputum can be conveniently sucked into the sampling tube 1 through the suction head 104, so that the sputum can be directly introduced into the reagent bottle 2 for collection. By taking out the reagent bottle 2, the sputum can be conveniently and directly tested, without the trouble of extracting the sputum twice, which effectively improves the work efficiency.

[0022] A limiting tube 4 is fixedly installed on the top of the sampling tube 1, and a movable groove 402 is opened on the inner wall of the limiting tube 4. A limiting ring 403 is movably installed inside the movable groove 402 through a reset spring 404. A bottle plug 6 is fixed between the limiting rings 403. By putting the bottle plug 6 into the limiting tube 4, the limiting ring 403 can be pushed to extend out of the inner wall of the limiting tube 4 through the elastic action of the reset spring 404. The limiting ring 403 can be used to support the bottle plug 6. The bottle plug 6 is connected with the reagent bottle 2, so that the bottle plug 6 and the reagent bottle 2 can be used together. The bottle plug 6 can be inserted into the bottle mouth of the reagent bottle 2, which can facilitate the sealing of the reagent bottle 2.

[0023] A sealing cover 401 is movably installed on the top of the limiting tube 4, and a pressing assembly 5 is arranged on the top of the sealing cover 401. The pressing assembly 5 includes a first pressing rod 501, a second pressing rod 502, a thrust spring 503 and a suction cup 504. The first pressing rod 501 runs through the sealing cover 401, so that the first pressing rod 501 can slide up and down on the sealing cover 401. A suction cup 504 is fixedly installed on the bottom of the first pressing rod 501. The second pressing rod 502 is rotatably installed on the top of the first pressing rod 501 through a rotating shaft. The outer sides of the first pressing rod 501 and the second pressing rod 502 are sleeved with a thrust spring 503. By pressing the second pressing rod 502, the first pressing rod 501 can be driven to move downward, so that the suction cup 504 can be brought into contact with the bottle stopper 6. By continuing to press, the limiting ring 403 can be exerted. The inner side of the limiting ring 403 is provided with an inclined slope, and when the bottle stopper 6 presses the limiting ring 403, the limiting ring 403 can be squeezed to both sides, so that the limiting ring 403 can move in the movable groove 402, so that the limiting ring 403 releases the limiting effect on the bottle stopper 6, so that the bottle stopper 6 can continue to move downward, and the bottle stopper 6 can be adsorbed by the suction cup 504, so as to prevent the bottle stopper 6 from falling off, and by continuing to press the second pressing rod 502, the bottle stopper 6 can be driven to contact the bottle mouth of the reagent bottle 2, and the bottle stopper 6 can be inserted into the bottle mouth of the reagent bottle 2, without taking out the reagent bottle 2, so as to facilitate the contactless sealing operation of the reagent bottle 2, and reduce the risk of bacterial infection, and through the action of the thrust spring 503, the second pressing rod 502 can be pushed to move upward for resetting, so as to facilitate the next pressing operation;

[0024] The pressing assembly 5 also includes an exhaust channel 505 and a docking channel 506. The second pressing rod 502 is provided with a docking channel 506, and the first pressing rod 501 is provided with an exhaust channel 505. The exhaust channel 505 is connected with the docking channel 506, and the docking channel 506 is connected with the suction cup 504. When the second pressing rod 502 is pressed, the exhaust channel 505 and the docking channel 506 are separated by rotating the second pressing rod 502, so that the docking channel 506 can be staggered. Sealing, when pressed, the air in the suction cup 504 can be squeezed out, so that the suction cup 504 can adsorb the bottle stopper 6. After the bottle stopper 6 and the reagent bottle 2 are sealed, the second pressing rod 502 is rotated in the opposite direction to make the exhaust channel 505 and the docking channel 506 correspondingly connected, so that the air can re-enter the suction cup 504, causing the suction cup 504 to lose its adsorption effect, and the suction cup 504 can be easily separated from the bottle stopper 6, so that the second pressing rod 502 can be smoothly reset.

[0025] The working principle of the sampling device for tuberculosis inspection based on the embodiment is as follows: by inserting the bottom of the reagent bottle 2 into the bracket 301, the pulling force of the tension spring 303 can be used to drive the sliding frame 302 to slide upward along the fixed frame 304, and the reagent bottle 2 can be driven to move upward by the bracket 301, so that the bottle mouth of the reagent bottle 2 is inserted into the docking port 105, and the sampling tube 1 is connected with the reagent bottle 2, and the sealing cover 401 is opened, and the bottle stopper 6 is placed in the limiting tube 4, and the bottle stopper 6 is supported by the limiting ring 403, and the sealing cover 401 is closed to seal the limiting tube 4, and the suction head 104 is placed in the patient's oral cavity, and by pulling the piston rod 101, sputum can be sucked into the sampling tube 1 through the suction head 104, so that the sputum can be directly introduced into the reagent bottle 2 for storage, and the exhaust channel 505 and the docking channel 506 are separated by rotating the second pressing rod 502, and the second pressing rod 502 is pressed. The pressing rod 502 moves downward, so that the suction cup 504 fits on the bottle stopper 6, which can squeeze out the air in the suction cup 504, so that the suction cup 504 can adsorb the bottle stopper 6. By continuing to press, the limiting ring 403 is squeezed and moves into the movable groove 402, which can contact the limit of the bottle stopper 6, so that the bottle stopper 6 can continue to be moved downward. By continuing to press, the bottle stopper 6 is inserted into the bottle mouth of the reagent bottle 2 for sealing. By flipping the second pressing rod 502 in the opposite direction, the exhaust channel 505 is made to correspond to the docking channel 506, so that air can enter the suction cup 504, so that the suction cup 504 releases the adsorption effect on the bottle stopper 6. The thrust spring 503 can push the second pressing rod 502 to move upward for reset. By pulling the bracket 301 downward, the reagent bottle 2 can be extracted, so that the medical staff can directly test the sputum in the reagent bottle 2, thereby improving work efficiency.
