[0002] Sheep quarantine is an important measure to ensure the health of sheep and prevent and control the spread of diseases. The process of sheep quarantine usually includes declaration and quarantine, acceptance, pre-slaughter inspection, synchronous quarantine and other links. During the quarantine process, quarantine personnel will carefully observe and inspect the health status, mental state, respiratory state, movement status, excrement characteristics, etc. of the sheep. At the same time, the meat products of sheep must also meet the relevant standards and requirements, such as no peculiar smell, no deterioration, no fishy smell, and the appearance color should be white, etc.;

[0003] Sheep blood sampling for quarantine belongs to biopsy, which requires drawing blood from the sheep's vein for testing. The maximum amount of blood drawn is 5% of the animal's total blood volume. Existing sheep blood sampling generally uses a syringe. After the blood is drawn, most of the piston rod of the syringe is exposed to the outside, which is easily pushed inward by external force, and the sampled blood is ejected from the needle, resulting in a waste of sampled blood. Therefore, the utility model proposes a sampling device for sheep quarantine to solve the above problem. Utility Model Content

[0019] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0020] according to Figure 1-5 As shown, this embodiment proposes a sampling device for sheep quarantine, including a syringe 1, a top cover 2, a bottom cover 3 and a needle 4. The top end of the syringe 1 is provided with a top cover 2, the bottom end of the syringe 1 is provided with a bottom cover 3, the bottom end of the bottom cover 3 is fixedly connected to the needle 4, and a piston 5 is provided inside the syringe 1. The top of the piston 5 is connected to a push-pull rod 7 through a snap-fit ​​mechanism. When the sampling device is in use, the top cover 2 is first removed from the top end of the syringe 1, so that the top end of the push-pull rod 7 leaks out from the top end of the syringe 1, and a protective cover is provided on the outside of the needle 4. After the protective cover is removed, the needle 4 is inserted into the sheep vein, and the piston 5 is pulled upward by the push-pull rod 7 to extract blood, then the push-pull rod 7 is removed, and the bottom cover 3 together with the needle 4 are also removed from the bottom of the syringe 1, and finally the top cover 2 is installed to the bottom end of the syringe 1 to completely seal the blood inside the syringe 1.

[0021] The engaging mechanism includes a socket 6, a plug 9, a slot 10 and a block 11. The top of the piston 5 is provided with a socket 6, the bottom end of the push-pull rod 7 is fixedly connected with a plug 9, the outer side of the plug 9 is fixedly connected with a block 11, the inside of the socket 6 is provided with a slot 10, the outer side of the plug 9 is closely connected with the inner side of the socket 6, the outer side of the slot 10 is set as an "L"-shaped structure, the diameter of the block 11 is equal to the width of the slot 10, when the push-pull rod 7 needs to be removed from the top of the piston 5, the plug 9 is first driven by the push-pull rod 7 Rotate inside the socket 6 so that the block 11 rotates to the bend of the slot 10, and then pull the push-pull rod 7 upward to completely move the block 11 out of the slot 10. At this time, the push-pull rod 7 has been separated from the socket 6 at the top of the piston 5, so as to remove the push-pull rod 7 from the top of the piston 5. When it is necessary to connect the push-pull rod 7 to the piston 5, insert the plug 9 at the bottom of the push-pull rod 7 into the socket 6, and drive the plug 9 to rotate through the push-pull rod 7, so that the block 11 is engaged in the depth of the slot 10. At this time, the push-pull rod 7 is connected to the piston 5.

[0022] The outer side of the piston 5 is fitted and connected with the inner side of the syringe 1. The shape of the piston 5 is set to an "I"-shaped structure. The size of the through hole at the top of the syringe 1 is smaller than the diameter of the piston 5. The piston 5 is pulled upward by the push-pull rod 7 to discharge the air in the syringe 1 and reduce the air pressure, so that the air pressure inside the sheep is greater than the air pressure inside the syringe 1. The pressure difference is used to drive the sheep's blood to automatically flow into the inside of the syringe 1.

[0023] The top and bottom ends of the syringe 1 are respectively fixedly connected with a No. 1 threaded tube 8 and a No. 2 threaded tube 15; the top end of the No. 1 threaded tube 8 is threadedly connected to the inner side of the top cover 2, and the bottom end of the No. 2 threaded tube 15 is threadedly connected to the inner side of the bottom cover 3; the top cover 2 is threadedly matched with the No. 1 threaded tube 8 at the top end of the syringe 1, and the bottom cover 3 is threadedly matched with the No. 2 threaded tube 15 at the bottom end of the syringe 1; the top cover 2 or the bottom cover 3 is rotated to remove or install the top cover 2 or the bottom cover 3 from the No. 1 threaded tube 8 or the No. 2 threaded tube 15.

[0024] The interior of the No. 2 threaded tube 15 is fixedly connected to a valve cover 12, and a plurality of through holes 13 are annularly distributed inside the valve cover 12. A valve plate 14 is fixedly connected inside the through hole 13. When the air pressure inside the syringe 1 is lower than the air pressure inside the sheep, the blood will flush open the valve plate 14 at the through hole 13, and the blood will flow into the interior of the syringe 1 through the through hole 13. When the needle 4 is pulled out from the sheep, the interior of the syringe 1 tends to balance, and the valve plate 14 returns to the inside of the through hole 13 and re-seals it, thereby preventing blood from leaking from the bottom of the syringe 1.

[0025] The push-pull rod 7 includes two plastic plates and an end cover. The two plastic plates are perpendicular to each other, and the top end of the plastic plate is fixedly connected to the end cover.

[0026] The sampling device for sheep quarantine is configured by first removing the top cover 2 from the top of the syringe 1 so that the top of the push-pull rod 7 leaks out from the top of the syringe 1. A protective sleeve is provided on the outside of the needle 4. After the protective sleeve is removed, the needle 4 is inserted into the sheep vein, and the piston 5 is pulled upward by the push-pull rod 7 to extract blood. Then, the plug 9 is driven by the push-pull rod 7 to rotate inside the socket 6, so that the block 11 rotates to the bend of the slot 10, and then the push-pull rod 7 is pulled upward to completely move the block 11 out of the slot 10. At this time, the push-pull rod 7 has been separated from the socket 6 at the top of the piston 5, so that the push-pull rod 7 is removed from the top of the piston 5, and the bottom cover 3 together with the needle 4 are removed from the bottom of the syringe 1. Finally, the top cover 2 is installed to the bottom end of the syringe 1 to completely seal the blood inside the syringe 1.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
