For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. This embodiment is written in a progressive manner.

[0018] like Figures 1 to 8 As shown, a blood sampling device for animal husbandry and epidemic prevention of the present invention comprises a fence 1, a mobile unit 2, a support plate 3 and a transmitter structure 4, wherein the fence 1 is used to enclose animals to prevent them from moving around at will, the mobile unit 2 is installed on the fence 1 and is used to provide power for the movement of the support plate 3, the transmitter structure 4 is installed on the support plate 3, and a counterweight column 5 is provided at the output end of the transmitter structure 4, and a needle 6 for piercing into the body of the animal is provided on the counterweight column 5; The mobile unit 2 is provided with a vacuum blood collection tube 8 , which is connected to the needle 6 via a hose 7 , and the hose 7 is provided with an extrusion structure for extruding and sealing the vacuum blood collection tube 8 .

[0019] In detail, due to the vacuum inside the vacuum blood collection tube 8, when the vacuum blood collection tube 8 is directly connected to the needle 6 through the hose 7, outside air will enter the vacuum blood collection tube 8, making the vacuum blood collection tube 8 no longer have the vacuum blood suction effect. Therefore, it is necessary to use an extrusion structure to squeeze the hose 7 and close it to prevent air from entering the vacuum blood collection tube 8.

[0020] The fence 1 is used to confine animals to prevent them from moving around at will. The mobile unit 2 is installed on the fence 1 and is used to adjust the position of the support plate 3, so that the position of the transmitter structure 4, the counterweight column 5 and the needle 6 on the support plate 3 can be adjusted, thereby facilitating blood drawing tests on different body parts of the animal. The transmitter structure 4 is fixed on the support plate 3 and is used to launch the counterweight column 5 and the needle 6. The counterweight column 5 is used to increase the weight of the needle 6 so that the needle 6 has a certain mass, which can facilitate the needle 6 to smoothly penetrate into the animal's body due to inertia. The hose 7 can connect the needle 6 and the vacuum blood collection tube 8.

[0021] When in use, the fence 1 is opened and the animal is driven into the fence 1, the support plate 3 and the structure thereon are moved to the specified position by the moving unit 2, the launcher structure 4 launches the counterweight column 5 and the needle 6 until the animal stretches, the needle 6 penetrates into the animal's body, the squeezing tube stops squeezing the hose 7, and the vacuum blood collection tube 8 uses its internal vacuum suction to suck the blood in the animal's body into the vacuum blood collection tube 8 through the hose 7 and the needle 6, thereby realizing an automatic blood sampling working mode.

[0022] It should be pointed out that after completing a blood drawing, the needle 6, hose 7 and vacuum blood collection tube 8 need to be replaced to avoid bacterial infection, and the vacuum blood collection tube 8 can also adopt a blood suction structure such as a syringe, a negative pressure tube, etc. When the blood drawing work is completed, the worker removes the counterweight column 5 and the needle 6 from the animal by pulling the hose 7, and takes away the vacuum blood collection tube 8 for testing.

[0023] Fixing the animal by the fence 1 can effectively reduce the stress response of the animal due to tension and fear during the blood drawing process, and the use of automatic blood sampling can reduce direct contact between humans and animals, reducing the risk of staff being attacked; the mobile unit 2 can help to quickly adjust the position of the needle for blood drawing, making the blood drawing process more efficient and quick, and convenient for blood drawing operations at multiple locations of the animal; in summary, this automated blood sampling device can significantly improve the safety and efficiency of the blood drawing process, while also improving the quality of the sample and reducing dependence on manpower.

[0024] Furthermore, a rubber pad 9 is provided on the counterweight column 5; The launcher structure 4 includes a launching cylinder 10 fixed on the supporting plate 3. The interior of the launching cylinder 10 is hollow. An insertion hole 11 and two sliding holes 12 are provided at the end of the launching cylinder 10. The insertion hole 11 and the two sliding holes 12 are communicated with the interior of the launching cylinder 10. The counterweight column 5 is inserted into the insertion hole 11. A slide plate 13 is slidably arranged in the launching cylinder 10. A top column 14 used in conjunction with the two sliding holes 12 is arranged on the slide plate 13. The slide plate 13 is connected to the launching cylinder 10 by a spring 15.

[0025] In detail, when the needle 6 penetrates into the animal's body, the rubber pad 9 contacts the animal's epidermis, thereby using the rubber pad 9 to limit the penetration depth. The insertion hole 11 and the sliding hole 12 are both located at one end of the launching cylinder 10, and the counterweight column 5 is inserted into the insertion hole 11. When launching the counterweight column 5 and the needle 6, the slide plate 13 is pushed to move in the launching cylinder 10 and compress the spring 15. The air in the space on the left and right sides of the slide plate 13 can flow through the gap between the slide plate 13 and the inner wall of the launching cylinder 10, releasing the slide plate 13. The spring 15 can push the slide plate 13 and the top column 14 to move quickly. The ends of the two top columns 14 respectively pass through the two sliding holes 12 and hit the rubber pad 9, thereby using the two top columns 14 to provide impact force to the rubber pad 9, so that the rubber pad 9 drives the counterweight column 5 and the needle 6 to move quickly toward the animal, thereby providing power for the launching of the counterweight column 5 and the needle 6.

[0026] Furthermore, a metal plate 17 is disposed on the slide plate 13 , and an electromagnetic generator 16 is disposed in the launching cylinder 10 .

[0027] In detail, when it is necessary to launch the counterweight column 5 and the needle 6, the electromagnetic generator 16 is energized, the electromagnetic generator 16 generates suction on the metal disk 17, the metal disk 17 pulls the slide plate 13 to move and compresses the spring 15. When the slide plate 13 moves to the specified position, the electromagnetic generator 16 is powered off, the spring 15 pushes the slide plate 13 to move quickly and uses the top column 14 to impact and release the counterweight column 5 and the needle 6.

[0028] Furthermore, a first arc-shaped magnet 18 and a second arc-shaped magnet 19 are provided between the rubber pad 9 and the launching cylinder 10 . The first arc-shaped magnet 18 is fixed on the launching cylinder 10 , and the second arc-shaped magnet 19 is fixed on the rubber pad 9 .

[0029] In detail, by setting the first arc magnet 18 and the second arc magnet 19, the counterweight column 5 and the needle 6 can be fixed on the launching cylinder 10 in a natural state. When the top column 14 hits the rubber pad 9, it overcomes the mutual attraction between the first arc magnet 18 and the second arc magnet 19 and enables the counterweight column 5 and the needle 6 to move quickly.

[0030] Furthermore, the squeezing structure includes a rubber clamping groove 20 for fixing the vacuum blood collection tube 8 and two squeezing plates 21 for clamping the hose 7, wherein a cylinder 22 is arranged on one of the squeezing plates 21 and the position of the other squeezing plate 21 is fixed.

[0031] In detail, the vacuum blood collection tube 8 is inserted into the rubber card slot 20, and the cylinder 22 can squeeze the hose 7 onto another squeezing plate 21 through one squeezing plate 21, thereby deforming and sealing the hose 7, so that the vacuum blood collection tube 8 and the needle 6 are isolated from each other.

[0032] Furthermore, the mobile unit 2 includes a stand 23 and two sliders 24 vertically slidably mounted on the stand 23, a support shaft 25 is provided between the two sliders 24, the support plate 3 is fixed on the support shaft 25, the rubber slot 20, the cylinder 22 and an extrusion plate 21 are all fixed on the stand 23, and another extrusion plate 21 is mounted on the cylinder 22; A plurality of arc-shaped slots 26 are provided on the side wall of the stand 23, and circular holes are provided on the two sliders 24. A clamping column 27 is rotatably inserted in the two circular holes. The cross-sectional shape of the clamping column 27 is semicircular. Limiting plates 28 are provided at both ends of the clamping column 27. The two limiting plates 28 are located on the outer sides of the two sliders 24, and the limiting plates 28 are attached to the side walls of the sliders 24. A first limiting block 29 is rolled on one limiting plate 28, and a second limiting block 30 is contacted with the first limiting block 29. The second limiting block 30 is fixed on the slider 24, and the second limiting block 30 is connected to the limiting plate 28 by a spring piece 31.

[0033] In detail, the spring piece 31 provides elastic force for the limit plate 28 and the clamping column 27, and the second limit block 30 and the first limit block 29 limit the rotation angle of the limit plate 28. In the natural state, the clamping column 27 rotates in the circular hole and is located on the side close to the stand 23. At this time, the clamping column 27 is clamped into an arc-shaped clamping groove 26, thereby using the clamping column 27 to lock the position of the slider 24 on the stand 23. When it is necessary to adjust the height position of the support plate 3, the limit plate 28 and the clamping column 27 are rotated to make the clamping column 27 deviate from the arc-shaped clamping groove 26. At this time, the first limit block 29 is separated from the second limit block 30, and the spring piece 31 is elastically deformed, and the slider 24 can slide freely on the stand 23. When the slider 24 slides to the specified position, the limit plate 28 is released, and the spring piece 31 pushes the clamping column 27 to rotate and re-clamp into the corresponding arc-shaped clamping groove 26, thereby realizing the adjustment of the position of the support plate 3 and the locking of the support plate 3.

[0034] Furthermore, the support shaft 25 is rotatably connected to the slider 24, and an adjustment disk 32 is provided on the support shaft 25. The adjustment disk 32 has an arc-shaped opening 33, and bolts are inserted into the arc-shaped opening 33. The bolts are fixed to the slider 24, and the position of the adjustment disk 32 is locked by the bolts and nuts.

[0035] In detail, when the pitch angle of the support plate 3 needs to be adjusted, the bolts can be loosened and the adjustment disk 32 can be rotated to rotate the support shaft 25 and the support plate 3. The adjustment disk 32 can be locked on the slider 24 using bolts and nuts to lock the position of the support plate 3.

[0036] Furthermore, the mobile unit 2 also includes a guide rail 34 laterally arranged on the fence 1, a moving seat 35 is slidably arranged on the guide rail 34, the stand 23 is fixed on the moving seat 35, a motor 36 is arranged on the fence 1, and a screw 37 is arranged at the output end of the motor 36, and the screw 37 passes through the moving seat 35 and is threadedly connected to each other.

[0037] In detail, the motor 36 can push the moving seat 35 to slide horizontally on the guide rail 34 through the screw 37, and the moving seat 35 drives the stand 23 to move horizontally, thereby adjusting the position of the support plate 3 in the horizontal direction.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention.
