[0002] Biotechnology refers to the science and technology that uses "living organisms (including animals, plants and microorganisms)" to produce useful substances or improve products, improve the characteristics of organisms, reduce costs and innovate species. When biotech pharmaceutical products are produced, sampling and detection are required to improve the quality of pharmaceutical products. However, most of the existing sampling devices for biotech detection are that testers use rubber pipettes to suck detection samples. Since biotech requires the detection of various samples, multiple groups of rubber pipettes are prone to be mixed, which affects the detection results. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments; based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0016] As shown in Figure 1 , Figure 2 and Figure 3As shown in the figure, a sampling device for biotech detection proposed by the present utility model includes a sampling tube 1, a rubber head 2, a vacuum self - suction structure 3, and a straw structure 4. The rubber head 2 is slidably disposed within the sampling tube 1. The vacuum self - suction structure 3 is disposed on the sampling tube 1, and the straw structure 4 is disposed on the sampling tube 1. The vacuum self - suction structure 3 includes a vacuum tube 5, a sealing sleeve 6, a partition plate 7, a rubber gasket 8, a sealing film 9, a fixing plate 10, a pressing head 11, a needle 12, a spring 13, an air - suction hole 14, and an exhaust hole 15. The vacuum tube 5 is thread - sealed on the sampling tube 1. The sealing sleeve 6 is wrapped around the gap between the sampling tube 1 and the vacuum tube 5. The partition plate 7 is fixedly disposed within the vacuum tube 5. The rubber gasket 8 is sealed on the partition plate 7. The sealing film 9 is sealed on the partition plate 7. The fixing plate 10 is fixedly disposed on the vacuum tube 5. The pressing head 11 is sealed on the vacuum tube 5. The needle 12 is fixedly disposed on the pressing head 11. One end of the spring 13 is fixedly disposed on the needle 12 and the other end is fixedly disposed on the fixing plate 10. The air - suction hole 14 penetrates through the needle 12. The exhaust hole 15 penetrates through the needle 12 and is connected to the air - suction hole 14.

[0017] As Figure 1 , Figure 2 and Figure 3 shown in the figure, the straw structure 4 includes a plug 16, a first straw 17, and a second straw 18. The plug 16 is inserted and removed from the sampling tube 1. The first straw 17 is fixedly disposed on the plug 16. The second straw 18 is slidably disposed within the first straw 17.

[0018] As Figure 1 , Figure 2 and Figure 3 shown in the figure, the sampling tube 1 is disposed between the plug 16 and the vacuum tube 5. The spring 13 is disposed between the pressing head 11 and the fixing plate 10.

[0019] As Figure 1 , Figure 2 and Figure 3 shown in the figure, the needle 12 is perpendicular to the partition plate 7. The rubber gasket 8 is perpendicular to the sealing film 9.

[0020] As Figure 1 shown in the figure, the inside of the vacuum tube 5 is set to be a one - time vacuum.

[0021] As Figure 1 and Figure 3 shown in the figure, the front end of the first straw 17 has a smaller diameter and the rear end has a larger diameter. The front end of the second straw 18 has a smaller diameter and the rear end has a larger diameter. The rear end of the second straw 18 can be limited and fixed at the front end of the first straw 17.

[0022] During specific use, when a user uses this device, first install the plug 16 onto the sampling tube 1, then pull out the second pipette 18 from the first pipette 17 so that the second pipette 18 can be inserted into the sample. Then hold the vacuum tube 5 and pull out the spring 13 from the vacuum tube 5. Press the pressing head 11. At this time, the pressing head 11 presses the spring 13 downward, thereby pushing the needle 12 downward. At this time, the needle 12 pierces the rubber pad 8 and the sealing film 9. At this time, the air intake hole 14 on the needle 12 is inserted into the sampling tube 1. At this time, the air in the sampling tube 1 passes through the air intake hole 14 and is discharged into the vacuum tube 5 through the exhaust hole 15. At this time, the pressure in the sampling tube 1 becomes smaller. At this time, the rubber head 2 slides upward in the sampling tube 1 under the action of the pressure. At this time, the sample liquid is sucked into the sampling tube 1 through the second pipette 18 and the first pipette 17, thus completing automatic sampling. Since the vacuum in the vacuum tube 5 is for single use, it avoids repeated use and mixing, and the problem of inaccurate detection results. The above is the entire usage process of the sampling device for biotech detection.
