[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1: The top of the collection tank 1 is integrally formed with an external thread seat 101. The inner wall of the sealing cover 4 is provided with an internal thread groove 401. An installation groove 11 is fixed on one side of the top of the sealing cover 4. A lead screw 9 is installed inside the installation groove 11 through a bearing. A threaded slider 10 is fitted on the outside of the lead screw 9 through threaded engagement. One end of the threaded slider 10 slides out of the installation groove 11. A sliding plate 6 is welded to one side of the threaded slider 10. A connecting rod 12 is welded to the bottom of the sliding plate 6. A sampling tube 3 is fixed to the bottom of the connecting rod 12. A leak-proof component 2 is installed on one side of the sampling tube 3. The sampling tube 3 is slidably installed inside. There is a piston rod 13, and a piston plate 14 is fixed to the bottom end of the piston rod 13. The top end of the piston rod 13 slides through the interior of the slide plate 6. A pull rod 5 is fixed to the top of the piston rod 13. The leak-proof component 2 includes a rotating rod 201 and a limiting block 204. The limiting block 204 is fixed to one side of the sampling tube 3. The outer side of the rotating rod 201 is rotatably installed inside the limiting block 204. A baffle 203 is fixed to the bottom of the rotating rod 201, and the baffle 203 works in conjunction with the sealing groove 301. A knob 202 is fixed to the top of the rotating rod 201. A sealing groove 301 is opened on one side of the sampling tube 3, and the bottom of the sampling tube 3 is open.

[0021] Specifically, such as Figure 1 , Figure 2 and Figure 4As shown, when a patient needs to vomit, the collection container 1 can be used to collect the patient's vomit. Then, the sealing cap 4 is placed on top of the collection container 1, and the inner threaded groove 401 and the outer threaded seat 101 are sealed together by rotating the sealing cap 4, allowing the sampling tube 3 to be inserted into the collection container 1. The vomit is then transferred to the testing mechanism for sampling and testing. During sampling, pulling the lever 5 upwards causes the piston plate 14 to move upwards inside the sampling tube 3, thereby extracting samples of the vomit collected in the collection container 1. After a certain amount of vomit has been sampled, it needs to be injected into the testing container. During the transfer process, to prevent the vomit inside the sampling tube 3 from dripping from the bottom of the sampling tube 3, Rotating the knob 202 causes the rotating rod 201 to rotate, which in turn causes the baffle 203 to rotate synchronously. By rotating the baffle 203, it is inserted into the sealing groove 301, thereby sealing the bottom of the sampling tube 3 and preventing the vomit inside the sampling tube 3 from dripping down. Then, the sliding plate 6 is controlled to move upward, causing the sampling tube 3 to slide out of the collection tank 1. The baffle 203 is then rotated out of the sealing groove 301, and the vomit sucked out of the sampling tube 3 is injected into the testing container. This sampling device can ensure that the vomit sampled will not leak during subsequent transfer, avoiding contamination of medical staff's limbs and the medical environment, thereby improving the accuracy of the test results.

[0022] Example 2: A limiting groove 403 is provided on the top of the sealing cover 4, and a rubber scraper 402 is installed inside the limiting groove 403. The sampling tube 3 and the leak-proof component 2 are slidably installed between the limiting groove 403. A rocker arm 7 is rotatably installed on the top of the mounting groove 11, and the output end of the rocker arm 7 extends into the interior of the mounting groove 11 and is fixedly connected to the top of the lead screw 9. A support slide rod 8 is welded to one side of the top of the sealing cover 4, and the interior of one end of the slide plate 6 is slidably sleeved on the outside of the support slide rod 8.

[0023] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, rotating the rocker arm 7 can drive the lead screw 9 to rotate. When the lead screw 9 rotates, it will cause the threaded slider 10 sleeved on the outside of the lead screw 9 to slide up and down along the installation direction of the lead screw 9. Since one end of the threaded slider 10 extends out of the mounting groove 11 and is fixedly connected to one end of the slide plate 6, and the inside of one end of the slide plate 6 is slidably sleeved on the outside of the support slide rod 8, when the threaded slider 10 moves, it will drive the slide plate 6 to slide along the installation direction of the support slide rod 8, thereby driving the sampling tube 3 to move up and down and insert the sampling tube 3 into the slide plate 8. When the sampling tube 3 is pulled out of the collection tank 1, the rubber scraper 402 will stick to the outer wall of the sampling tube 3 and the leak-proof component 2, thus scraping off the vomit on the outer wall of the leak-proof component 2 and the sampling tube 3, ensuring that the vomit on the outer wall of the leak-proof component 2 and the sampling tube 3 is not present, and further avoiding contamination of the medical staff's limbs and the medical environment.

[0024] Working principle: When a patient needs to vomit, the collection container 1 can be used to collect the patient's vomit. Then, the sealing cap 4 is placed on top of the collection container 1. By rotating the sealing cap 4, the inner thread groove 401 and the outer thread seat 101 are sealed together, allowing the sampling tube 3 to be inserted into the collection container 1. During sampling, pulling the lever 5 upwards moves the piston plate 14 upwards inside the sampling tube 3, thereby extracting the vomit collected inside the collection container 1. To prevent the vomit inside the sampling tube 3 from leaking out... The vomit drips from the bottom. Rotating the knob 202 causes the rotating rod 201 to rotate, which in turn causes the baffle 203 to rotate synchronously. By rotating the baffle 203, the baffle 203 is inserted into the sealing groove 301, thereby sealing the bottom of the sampling tube 3 and preventing the vomit inside the sampling tube 3 from dripping down. Then, the sliding plate 6 is controlled to move upward, causing the sampling tube 3 to slide out from the inside of the collection tank 1. Then, the baffle 203 is rotated out from the sealing groove 301, and the vomit sucked in the sampling tube 3 is injected into the testing container.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
