Technical Field

[0001] The invention relates to the technical field of blood sampling devices for animal husbandry and veterinary pigs, and in particular to a blood sampling device for animal husbandry and veterinary pigs with a draw hook fixing function. Background Art

[0002] In the process of animal husbandry, blood testing and inspection are essential in the pig farm breeding process, such as sampling blood from the immunized breeding pigs and nursery pigs to test the antibody level in the blood and evaluate the vaccine immunity effect; blood testing of the pigs to exclude those with positive antibodies to specific pathogens and establish disease purification pigs; timely blood testing can detect sick pigs as early as possible and treat them in time to avoid infection, etc. There are many ways to draw blood from farmed pigs. After comparison, it is found that the anterior vena cava blood drawing technology is a technical means that takes less time and is more convenient to operate. At this time, a special blood drawing device is needed.

[0003] The blood sampling devices for pigs used by animal husbandry and veterinary medicine on the market are not convenient for fixing the limbs of pigs according to their body size before blood sampling. They have great limitations and can only be used for sick pigs, healthy pigs or large and small pigs. They have average stability. When the pigs resist too much during blood sampling, the device may easily fall over. The pigs are less comfortable when fixed and may easily resist significantly due to the low comfort level of the binding. In view of the above situation, technical innovation is carried out on the basis of the existing blood sampling devices for animal husbandry and veterinary medicine. For this reason, we propose a blood sampling device for pigs used by animal husbandry and veterinary medicine with a hook fixing function that can prevent the device from falling over due to the pigs' excessive resistance during blood sampling. Before blood sampling, the device can be quickly adjusted to a suitable angle for fixing the pigs' limbs. The device has better flexibility and can fix the pigs' limbs according to their body size. The device is not limited to sick pigs, healthy pigs or large and small pigs. The device can improve the comfort level of the pigs when they are fixed and avoid the pigs' significant resistance due to the low comfort level of the binding.

[0026] Furthermore, the cover plate 3 forms a detachable structure with the base 1 through the limiting groove 2, and the base 1 is welded to the lying plate 14. With such a configuration, when the device is in use, the weight of the base 1 is increased by the counterweight block, so that the stability of the base 1 is stronger, and the phenomenon that the device is tipped over due to excessive resistance of the pig during the blood collection process can be prevented, which is conducive to improving the stability of the device and making the device more convenient when in use;

[0027] Furthermore, the outer cylinder 5 forms a rotating structure with the base 1 through the bearing 4, and the outer cylinder 5 and the clamping rod 6 are in a clamping connection. With such a setting, the angle of the device can be adjusted through a simple setting, making the device more flexible.

[0028] Furthermore, the clamping rod 6 and the inner tube 7 are arranged perpendicular to each other, and the clamping rod 6 and the clamping slot 8 are connected by clamping. Such an arrangement is conducive to the user to adjust the structure of the device, making the device more practical.

[0029] Furthermore, the card slots 8 are evenly spaced on the outer wall of the inner tube 7, and the inner tube 7 and the outer tube 5 form an elastic structure through the first spring 9. With this arrangement, before the blood collection operation on the pig, the device can be quickly adjusted to an angle suitable for fixing the pig's limbs. The height and angle of the device fixing structure can be adjusted through simple settings, making the device more flexible and improving the practicality of the device.

[0030] Furthermore, the movable hook 11 forms a rotating structure with the first telescopic belt 10 through the rotating shaft 12, and the cross-sectional shape of the movable hook 11 is set in a "C" shape. With such a setting, the limbs of the pig can be fixed according to the size of the pig through the stretching of the first telescopic belt 10, and the use is not limited to sick pigs, healthy pigs or large and small pigs, so that the application range of the device is wider, and the limbs of the pig can be fixed more effectively, so that the pig cannot resist significantly during the blood collection process, which is conducive to the subsequent treatment of the veterinarian;

[0031] Furthermore, the second telescopic belt 18 forms a sliding structure with the slider 17 and the slide groove 16, and two second telescopic belts 18 are symmetrically arranged about the central axis of the lying board 14. Such an arrangement can facilitate the user to initially fix the pig. The pig can be fixed above the lying board 14 through simple operation. The pig is in a supine position and has less resistance. In addition, such a moving cross-type fixation of the pig has a better fixation effect. At the same time, it can be adjusted according to the body shape of the pig, which can improve the comfort of the pig when being fixed and avoid the pig from having a large resistance due to the low comfort of the binding.

[0032] Working principle: When using the animal husbandry and veterinary blood sampling device with a hook fixing function for pigs, first, in the preparation stage of the device, the clamping rod 6 is first taken out from the clamping groove 8 on the outer wall of the inner tube 7 and the outer tube 5, so that the inner tube 7 bounces upward through the action of the first spring 9, and then after bouncing to a suitable position, the clamping rod 6 is used to fix the clamping groove 8 on the outer wall of the inner tube 7 and the outer tube 5 again, so that the inner tube 7 is adjusted to a height suitable for the body shape of the pig to be blooded, and then the outer tube 5 is rotated through the action of the bearing 4, so that the device can be quickly adjusted to a suitable angle for fixing the pig's limbs. Before the pig is blooded, the height and angle of the device fixing structure can be adjusted through simple settings. When the device is in use, a suitable counterweight block is selected according to the weight of the pig and placed in the placement groove inside the cover plate 3, and then the cover plate 3 is clamped and fixed to the bottom of the base 1 through the limit groove 2. When the device is in use, the weight of the base 1 is increased by the counterweight block, so that the stability of the base 1 is stronger, which can prevent the device from tipping over due to excessive resistance of the pig during the blood collection process;

[0033] After the user places the pig with its back facing downward on the lying board 14, the user pulls the second telescopic belts 18 on both sides according to the pig's body shape. The second telescopic belts 18 slide inside the slide groove 16 through the slider 17 under the action of the pulling force. After sliding until the two sides of the second telescopic belts 18 are located on both sides of the pig's body, the second telescopic belts 18 are passed through the inside of the fixing block 19, and then the second telescopic belts 18 are passed through the fixing blocks 19 on the opposite sides respectively, and then the second telescopic belts 18 are fastened and fixed to the outer wall of the fixing block 19. The pig is in a supine position, and the pig's resistance is less limited. In addition, the cross-moving fixing effect of the pig is better, and it can be adjusted according to the pig's body shape. After the pig's body is fixed, the movable retractor 11 is stretched to the position of the pig's limbs. , clamp the movable hooks 11 on both sides to the middle position of one end, the other end of the movable hook 11 is opened by the action of the rotating shaft 12, and the second spring 13 inside is contracted, and the pig's limbs are inserted into the movable hook 11, and one end of the movable hook 11 is released, and the movable hook 11 immediately rebounds by the action of the second spring 13, thereby clamping and fixing the pig's limbs. The first telescopic belt 10 can be stretched to fix the pig's limbs according to the size of the pig, and is not limited to sick pigs, healthy pigs or large and small pigs, so that the device has a wider range of applications, and can more effectively fix the pig's limbs, so that the pig cannot resist significantly during the blood collection process, which is beneficial for veterinarians to carry out subsequent treatment.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
