Description

Technical Field

[0001] The utility model relates to the field of sampling devices, in particular to a sampling device for gene detection. Background Art

[0002] Emu is a species of the genus Emu in the family Emuidae. It has high economic value. For example, its fat can be used to produce cosmetics, its leather can be used to make wallets, handbags, shoes and clothes, its feathers can be used as decorations, its beaks and claws can be carved into jewelry, and its eggshells can be used as egg carving artworks. They are also an important medium for spreading seeds and have ecological value. When studying emus, in addition to blood component analysis, genetic testing of emus is also required, so sampling devices are used. Since emus are birds, their feathers carry little DNA, which is not conducive to genetic testing. Therefore, for emus, blood is often used for genetic testing, so the sampling device required is usually a blood sampling device.

[0003] When the blood sampling device is in use, the puncture needle is inserted into the disinfected vein, and the pipe at the end of the puncture needle is connected to the vacuum tube through a joint. Under the action of negative pressure, the blood in the vein is drawn into the blood sampling tube, thereby achieving sampling. However, in the existing blood sampling device, when operating the puncture needle, the operating part is only provided with an operating handle, which is extremely inconvenient to operate and inconvenient to change hands. In addition, when placing the blood sampling tube, it must be placed on a test tube rack. When there is no test tube rack, the blood sampling tube can only be placed horizontally on the table, which is prone to rolling and falling, and the stability of use is poor. Utility Model Content

[0021] When using the sampling device to collect blood from an emu, ensure that the emu is in a quiet state, collect blood from the jugular vein or femoral vein of the emu, disinfect the blood collection site, and then insert the needle 7 into the vein at the blood collection site through the operating component 6. During this process, the first operating panel 602 on the connecting tube 601 can be used for operation, or the second operating panel 603 can be pinched for operation, making the operation convenient and quick. After the needle 7 is inserted into the vein, the connector 3 is connected to the end 2 on the sampling tube 1, and the vacuum negative pressure in the sampling tube 1 performs the blood drawing operation. The blood in the emu's venous blood vessels enters the sampling tube 1 from the blood drawing tube 5, thus realizing the sampling work. In this process, the stabilizing structure 4 can be used to ensure the stable holding of the sampling tube 1. When the sampling is completed, the needle 7 is pulled out, and the puncture site is disinfected to stop bleeding. Then the staff can perform genetic testing on the blood. Before the test, the stabilizing structure 4 can be used to stably place the sampling tube 1. The sampling tube 1 does not need to be placed on a test tube rack to ensure the vertical and stable placement of the sampling tube 1, which ensures the stability of the sampling tube 1 and prevents the sampling tube 1 from rolling to the ground and being damaged.

[0022] Through the above implementation scheme, the stabilizing structure 4 includes a connecting sleeve 401, a limiting plate 402 and a supporting plate 405. The connecting sleeve 401 is fixedly connected to the limiting plate 402, and the connecting sleeve 401 is installed at the lower end of the sampling tube 1. The supporting plate 405 is sleeved between the two limiting plates 402 on the connecting sleeve 401. The stabilizing structure 4 also includes a screw hole 403, a snap-on protrusion 404, a groove 406 and a snap-on groove 407. The screw hole 403 is provided on the connecting sleeve 401, and the connecting sleeve 401 is fixed to the lower end of the sampling tube 1 through the screw hole 403 and the external thread 8. The two limiting plates 402 are fixed to the ends of the connecting sleeve 401. The snap-on protrusion 404 is arranged in a ring array on the limiting plate 402, the groove 406 is provided on the supporting plate 405, the snap-on groove 407 is provided on the supporting plate 405, and the snap-on groove 407 is provided on the supporting plate 405. The connecting grooves 407 are distributed in a circular array on the support plate 405, and the stabilizing structure 4 is installed at the lower end of the sampling tube 1 through the external thread 8. The stabilizing structure 4 is used to support and stabilize the sampling tube 1. In the absence of a test tube rack for placement, the sampling tube 1 can also be stably placed on the desktop to ensure the placement stability of the sampling tube 1. The stabilizing structure 4 is threadedly connected to the sampling tube 1 and can be quickly disassembled and reused. A groove 406 and a clamping groove 407 are provided on the support plate 405. When the support plate 405 is connected to the limiting plate 402 at the upper end of the connecting sleeve 401, the stabilizing structure 4 can be used to stably hold the sampling tube 1. When the support plate 405 is connected to the limiting plate 402 at the lower end of the connecting sleeve 401, the stabilizing structure 4 is used as a supporting component, and has high flexibility and adaptability.

[0023] When connecting the stabilizing structure 4, the connecting sleeve 401 is installed to the external thread 8 at the lower end of the sampling tube 1 through the screw hole 403, and then it starts to be used. During use, when holding the sampling tube 1, the support plate 405 contacts the limit plate 402 at the upper end of the connecting sleeve 401. At this time, the clamping protrusion 404 of the limit plate 402 at the upper end of the connecting sleeve 401 is inserted into the clamping groove 407 on the upper surface of the support plate 405. The staff can hold the sampling tube 1 firmly through the support plate 405, and when the sampling tube 1 needs to be placed, The support plate 405 can be moved to the limit plate 402 at the lower end of the connecting sleeve 401. The limit plate 402 is located in the groove 406. At the same time, the corresponding snap-in protrusion 404 is connected to the snap-in groove 407 in the groove 406. Then the sampling tube 1 is placed. At this time, the support plate 405 in the stabilizing structure 4 contacts the placement surface, providing stability for the sampling tube 1 and ensuring the stability of the sampling tube 1. When the sampling tube 1 needs to be processed after use, the stabilizing structure 4 can be disassembled and stored for reuse.
