Description

Technical Field

[0002] Pigs are a key animal species in my country's livestock industry, and their meat, leather, and other products are valuable agricultural products. However, pigs are susceptible to various diseases during their breeding process, resulting in significant economic losses for breeding companies. Therefore, to ensure the healthy development of the pig industry, the prevention and diagnosis of pig diseases are particularly important.

[0003] Blood sampling and testing is a routine task for large-scale pig farms. Blood tests are used to assess the health and growth of pigs. Blood sampling is not only performed on growing and finishing pigs, but also on piglets to facilitate timely detection of illness and prevent the spread of viruses by sick pigs. Piglets also require blood sampling before weaning to assess their growth and determine whether to wean them. This blood collection typically involves sampling from the anterior vena cava, which requires the pig to be restrained during blood collection. This method ensures stable and accurate blood collection. Currently, restraints for lighter and smaller piglets include U-shaped iron hooks and spring-loaded bed-style restraints. However, piglets can still move their limbs while on the U-shaped hooks, which interferes with blood collection from the anterior vena cava. Spring-loaded bed restraints, on the other hand, fail to properly expose the piglet's anterior vena cava, preventing blood collection. Utility Model Content

[0028] The following is combined with Figures 1 to 3 The technical solution of the utility model is further illustrated through specific implementation methods.

[0029] An experimental piglet restrainer, characterized by comprising a restraining plate 1, a bracket 2, a plurality of elastic adjustment members 31 and a plurality of elastic bands 32;

[0030] The top of the restraint board 1 is recessed downward to form a U-shaped receiving groove 11. The bracket 2 is provided at the bottom of the restraint board 1. The bracket 2 is used to support the restraint board 1. The receiving groove 11 is used to place piglets.

[0031] The outer wall of one side of the restraining plate 1 is provided with a plurality of elastic bands 32 and a plurality of elastic adjustment parts 31 at intervals along the length direction of the accommodating groove 11, and the elastic bands 32 correspond to the elastic adjustment parts 31 one by one; the fixed end of the elastic band 32 is provided with the elastic adjustment part 31, and the free end of the elastic band 32 is used to be wound around the restraining plate 1, and the free end of the elastic band 32 is successively passed through the bottom of the restraining plate 1 and the notch of the accommodating groove 11 and is provided on the elastic adjustment part 31, and a restraining ring 3 is formed between the winding of the elastic band 32 and the accommodating groove 11, and the elastic adjustment part 31 is used to lock the free end of the elastic band 32 and to adjust the size of the restraining ring 3.

[0032] The bracket 2 is arranged at the bottom of the restraint board 1 and is used to support the restraint board 1; the restraint board 1 is provided with a U-shaped receiving groove 11, in which the piglet can lie on its back and be stably placed; the outer wall of the restraint board 1 is provided with an elastic band 32 and an elastic adjustment part 31. After the piglet is placed on its back in the receiving groove 11, the free end of the elastic band 32 is moved from the bottom of the restraint board 1 to the groove opening of the closed receiving groove 11 and passed through the elastic adjustment part 31 to form a restraint ring 3, which restrains and fixes the piglet lying on its back in the receiving groove 11; several one-to-one corresponding elastic bands 32 and elastic adjustment parts 31 form several restraint rings 3 along the length direction of the receiving groove 11 to restrain and restrict different parts of the piglet, such as the head, forelimbs or hindlimbs. The unique elasticity of the elastic band 32 allows it to closely conform to the piglet's body contours, providing a more stable and uniform securing force. This design reduces discomfort during the restraint process and avoids the risk of blood collection failure or piglet escape due to insecure fixation. Because the elastic band 32 has a certain degree of elasticity, it can accommodate piglets of varying shapes and sizes. Whether it's a small newborn piglet or a slightly larger weaned piglet, the elastic band 32 can be adjusted to ensure stable fixation by adjusting the tension adjuster 31.

[0033] Specifically, when using the restrainer of the present invention, a worker places a supine piglet in the receiving groove 11 of the restraint board 1. The worker then sequentially wraps the free end of the elastic band 32 around the restraint board 1 until it passes through the elastic adjustment member 31, forming a restraint loop 3 to restrain the piglet. One restraint loop 3 is wrapped around the piglet's forelimbs, while the others are wrapped around other areas, such as the abdomen and hindlimbs. This exposes the piglet's forelimb veins, allowing blood sampling from the anterior vena cava.

[0034] By arranging an elastic band 32 and an elastic adjustment part 31 on the same side of the restraining board 1 to lock and adjust the elastic band, the operation of tying up the piglets can be simplified, and no multiple people are required to operate (one person restrains the piglets and the other ties the restraint band), which reduces the difficulty of operation and adjustment and the labor intensity of the operator; improves the stability of blood collection and also improves the accuracy of blood collection.

[0035] Furthermore, a mounting bracket 4 is provided on the outer side wall of the retaining plate 1, and the mounting bracket 4 is extended along the length direction of the retaining plate 1, and the mounting bracket 4 is provided with a plurality of through holes along the length direction, the elastic band 32 is passed through the through holes of the mounting bracket 4, and the fixed end of the elastic band 32 is restricted by the elastic adjustment member 31 and cannot pass through the mounting bracket 4, and a plurality of the elastic bands 32 are arranged in sequence along the extension direction of the mounting bracket 4.

[0036] The mounting frame 4 serves as a support structure for the elastic band 32. Its extension along the length direction of the restraint board 1 provides a more stable installation foundation for the elastic band 32. The position and number of the elastic bands 32 can be adjusted as needed. By increasing or decreasing the number of elastic bands 32, or adjusting their positions on the mounting frame 4, it can adapt to piglets of different shapes and sizes, ensuring that each piglet can be stably and comfortably fixed. In addition, installing the elastic band 32 on the mounting frame 4 makes the replacement, maintenance or adjustment of the elastic band 32 easier and faster. The operator does not need to perform complex operations directly on the restraint board 1. The relevant operations of the elastic band 32 can be easily completed through the mounting frame 4, thereby improving work efficiency and reducing maintenance costs.

[0037] Furthermore, a plurality of the penetration holes are interconnected to form a long strip penetration area, and the fixed end of the elastic band 32 can slide along the length direction of the long strip penetration area.

[0038] The fixed end of the elastic band 32 is inserted into the long strip of the mounting frame 4, allowing the elastic band 32 and the tension adjustment member 31 to be adjusted on the mounting frame 4. The operator can flexibly adjust the position and tightness of the elastic band according to the different body shapes and sizes of piglets and specific blood collection requirements. This design allows the restraint to better adapt to different situations and improves its adaptability and flexibility.

[0039] Furthermore, a Velcro 33 is provided at the free end of the elastic band 32, and the Velcro is used to adhere to the elastic band 32;

[0040] The tension adjusting member 31 is an adjusting buckle.

[0041] The combination of the adjustment buckle and the Velcro 32 makes the fixing and releasing process of the elastic band 32 very convenient. Figure 3 As shown, the operator simply passes the belt body around the top of the restraint board 1 in the direction from A to B, then crosses from one side of the slot opening of the receiving slot 11 to the other side in the direction from B to C, passes it through the adjustment buckle in the direction D, and then affixes the Velcro 32 to the belt body to complete the fixation. Similarly, when it is necessary to release the piglet, simply tear off the Velcro 32. This design greatly improves work efficiency and reduces the operator's labor intensity.

[0042] Furthermore, the number of the elastic adjusting members 31 and the number of the elastic bands 32 are three respectively.

[0043] The three corresponding elastic adjustment members 31 and the elastic band 32 can be wound to form three restraint rings 3, which respectively restrict and fix the position of the piglet's forelimbs, hind limbs and abdomen. The three restraint rings 3 can effectively fix the piglet and the operation is efficient.

[0044] Furthermore, there are several brackets 2, and the brackets 2 are detachably connected to the retaining plate 1.

[0045] The detachable bracket 2 allows the operator to flexibly select and combine the number and position of the brackets according to the specific use environment and needs. For example, in situations where a larger support area or higher stability is required, the number of brackets can be increased; in situations where space is limited, the number of brackets can be reduced to adapt to the environment. Similarly, by assembling brackets 2 of different heights at the bottom of the restraining plate 1, the restrainer can be made of different heights for easy application. This flexibility increases the scope of application and practicality of the restrainer.

[0046] Furthermore, the bottom of the retaining plate 1 is provided with a plurality of vertical threaded holes 12, the bracket 2 is provided with the threaded holes 12, and the bracket 2 and the retaining plate 1 are installed by screws passing through the threaded holes 12 in sequence.

[0047] The use of screws and threaded holes ensures a more stable and reliable connection between the retaining plate 1 and the bracket 2. Since both the retaining plate 1 and the bracket 2 utilize uniform threaded holes and screws, this facilitates standardized production and assembly of the retainer. This not only reduces production costs and complexity, but also improves product interchangeability and maintainability.

[0048] Furthermore, a buffer pad is provided in the receiving groove 11 .

[0049] The skin of piglets is relatively delicate and easily damaged by friction and squeezing. The introduction of the cushioning pad can significantly reduce the pressure and discomfort caused by direct contact between the piglet's body and the restraint board 1. The cushioning pad acts as a protective barrier to prevent the restraint board or other hard parts from directly contacting the piglet's skin, thereby avoiding problems such as skin wear, redness, swelling, and even damage.

[0050] The cushioning pad is usually made of easy-to-clean materials, such as removable cloth or washable rubber. This allows the operator to easily clean and disinfect the restrainer after use to ensure the hygiene standard for the next use.

[0051] Furthermore, the retaining plate 1 and the bracket 2 are plastic plates.

[0052] Plastic is relatively light, which reduces the overall weight of the restraint and makes it easier for operators to carry and move. This feature is particularly important when the restraint needs to be moved or adjusted frequently. In addition, plastic generally has good corrosion resistance and can withstand erosion by a variety of chemicals. In a pig farming environment, the restraint board may come into contact with various detergents, disinfectants, or pig excrement. Plastic can effectively prevent corrosion and extend the service life of the restraint. Furthermore, the plastic surface is smooth and not easy to adhere to dirt and bacteria, making it easier to clean and disinfect. This is important for maintaining the hygiene of the pig farming environment and preventing the spread of disease. Operators can use conventional detergents and disinfectants to clean and disinfect the restraint board to ensure that its hygiene conditions meet standards. Finally, the cost of plastic is relatively low, which reduces the manufacturing cost of the restraint, thereby improving its cost-effectiveness.

[0053] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will be able to devise other specific implementations of the present invention without inventive effort, and such implementations will fall within the scope of protection of the present invention.
