Description

Technical Field

[0001] This utility model relates to the field of blood collection positioning technology, and in particular to a livestock blood collection positioning device. Background Technology

[0002] The main purpose of livestock blood collection is to detect animal diseases and antibodies, and to provide a guarantee for the high-quality development of animal husbandry. By collecting blood samples from livestock and conducting laboratory tests, livestock blood collection can comprehensively assess and verify the status and effectiveness of centralized immunization against major animal diseases, and promptly summarize and identify shortcomings and deficiencies in disease prevention work.

[0003] Currently, when collecting blood from livestock, positioning devices are usually used to fix the animal's head in place to prevent the needle from shifting due to shaking during the blood collection process.

[0004] The prior art, disclosed in CN219048456U, describes a blood collection positioning device for livestock and veterinary medicine, which includes a blood collection base frame and a fixed side plate fixedly mounted on the blood collection base frame. A head perforation is provided in the middle of the fixed side plate, and a head support is fixedly mounted at the bottom of the head perforation. Adjustment grooves are provided on both sides of the head perforation.

[0005] Because of its fixed height, and the fixed shape and size of the head support and the fixed groove, which cannot be changed, it can only fix livestock of a specific height and that conform to the head support and the fixed groove. For other livestock that are taller or shorter or do not conform to the head support and the fixed groove, it is difficult to perform positioning and fixing operations, resulting in poor versatility of the blood collection positioning device. Therefore, an improvement is proposed. Utility Model Content

[0025] like Figures 1 to 3As shown, a livestock blood collection positioning device includes two base plates 1. A base 5 is fixedly connected to the top of both base plates 1. A manual bidirectional moving assembly is mounted on the base 5. Two movable ends of the manual bidirectional moving assembly are rotatably connected to a double-link assembly. A movable seat 8 is fixedly connected to the top of the double-link assembly. The manual bidirectional moving assembly includes a first handwheel 2. The first handwheel 2 is designed to facilitate manual operation of the manual bidirectional moving assembly. The first handwheel 2 is located on one side of the outer surface of the base 5. A bidirectional screw 3 is fixedly connected to one side of the outer surface of the first handwheel 2, and the bidirectional screw 3 penetrates the outer surface of the base 5. The wall extends into the interior and is rotatably connected thereto. Two slide blocks 15 are symmetrically threaded on the outer surface of the bidirectional screw 3, and the slide blocks 15 are slidably connected to the inner walls on both sides of the base 5. A guide rail can be set on the inner wall of the base 5. The guide rail and the slide block 15 cooperate to slide and ensure the stability of the movement of the slide block 15. The double linkage assembly includes two linkage bodies 14, and the linkage bodies 14 are rotatably connected to the adjacent slide blocks 15. The top of the two linkage bodies 14 are rotatably connected to a support block 13, and the support block 13 is fixedly connected to the movable seat 8. The setting of the support block 13 is conducive to the rotatable connection between the linkage body 14 and the movable seat 8.

[0026] A housing 7 is fixedly mounted on the top of the movable seat 8. A restraint strap 10 is provided on the top of the housing 7 for secure fastening, providing strong adaptability. Both ends of the restraint strap 10 extend through the top of the housing 7 into the interior. A winding wheel 16 is fixedly connected to both ends of the restraint strap 10, and the winding wheel 16 is rotatably mounted on one inner wall of the housing 7. A manual self-locking drive assembly is installed between the two winding wheels 16 and the housing 7. The manual self-locking drive assembly includes two worm gears 18, and the worm gears 18 are fixedly connected to the adjacent winding wheel 16. One side of the outer surface of each worm gear 18 is meshed with a worm 17. The helical direction of the two worms 17 can be selected according to the actual situation. However, it is required that after the two worms 17 drive the two worm gears 18 to rotate, the two winding wheels 16 can simultaneously wind up or release the two ends of the binding belt 10. The two worms 17 are fixedly connected to each other and rotatably connected to the housing 7. One end of each worm 17 extends through the inner wall of the housing 7 to the outside and is fixedly connected to a second handwheel 11. The second handwheel 11 is provided to facilitate manual driving of the two worms 17 to rotate.

[0027] A blood vessel observation component is fixedly installed on one side of the outer surface of the housing 7. The blood vessel observation component includes a cold light source blood vessel observation instrument 6, and the cold light source blood vessel observation instrument 6 is fixedly installed on one side of the outer surface of the housing 7.

[0028] A rubber pad 9 is fixedly installed on the top of the shell 7, and the rubber pad 9 is sleeved on the outer surface of the restraint strap 10. The setting of the rubber pad 9 can prevent livestock from making hard contact with the shell 7.

[0029] Working principle: During blood collection, counterweights can be added to the two base plates 1 as needed. Then, the height of the housing 7 can be adjusted as required. Turning the first handwheel 2 rotates the double-acting screw 3, which in turn moves the two sliding blocks 15 closer together. This, in turn, moves the bottoms of the two connecting rod bodies 14 closer together. The connecting rod bodies 14, in conjunction with the support block 13, raise the height of the movable seat 8, thus raising the height of the housing 7 until the desired height is reached. Then, the animal's head is passed through the restraint strap 10, and the second handwheel is manually activated. When wheel 11 rotates, the second handwheel 11 drives the two worm gears 17 to rotate. The two worm gears 17 drive the worm wheels 18 connected to them to rotate. The worm wheels 18 drive the winding wheels 16 connected to them to rotate. The two winding wheels 16 work together to wind up both ends of the restraint strap 10 until the head of the livestock is fixed to the rubber pad 9 on the top of the shell 7 through the restraint strap 10. Then, the position of the cold light source 4 is adjusted so that it faces the neck of the livestock to be blooded. At this time, the veterinarian can directly observe the direction of the blood vessels in the neck of the livestock and then perform the blood collection operation.
