[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] Example 1

[0027] refer to Figures 1 to 3 A novel pig restraint, comprising:

[0028] Mounting bracket 4;

[0029] The head and back pressing arc plate 3 is located on the upper part of the fixing frame 4 and is fixedly connected to the fixing frame 4.

[0030] In practice, the size of the head and back pressing arc plate 3 fully considers the length and width ratio of the head and back of pigs of different weights, so that when the pig lies supine, the back force is on the arc plate, and the back and head are fully fixed inside the arc plate.

[0031] Two front restraint posts 1 are arranged symmetrically and fixed to both sides of the first end of the fixing frame 4 to fix the pig's forelimbs.

[0032] Two rear restraint posts 2 are symmetrically arranged and movably installed on both sides of the second end of the fixing frame 4 to fix the pig's hind limbs.

[0033] In practice, the limbs can be firmly fixed when the pig is lying on its back to prevent shaking and make the pig more comfortable.

[0034] This utility model is applicable to general animal husbandry, grassroots veterinary medicine, schools, scientific research, clinical practice, and laboratories, and can be widely promoted and used.

[0035] Preferably, it is made of stainless steel.

[0036] Made of stainless steel, the surface is smooth and without sharp corners, preventing injury to laboratory animals and personnel during handling. Stainless steel is easy to clean, wash, and disinfect, making it suitable for animal housing, school and research laboratory facilities, and high-level biosafety laboratories. It allows for thorough disinfection and cleaning after experiments, enabling reuse.

[0037] This novel pig restraint device is more convenient, practical, and unique, with excellent biosafety to meet the needs of various experiments, making it more practical.

[0038] In this embodiment, the first end of the front restraint post 1 is fixedly connected to the fixing frame 4, and the second end extends outward to the upper side of the fixing frame 4. Multiple first fixing rods 6 are provided at intervals at the second end of the front restraint post 1.

[0039] In this embodiment, the first end of the rear restraint post 2 is movably mounted on the fixing frame 4, and the second end extends outward at an angle to the upper side of the fixing frame 4. The second end of the rear restraint post 2 is provided with multiple second fixing rods 7 at intervals.

[0040] In practice, the head and back are fixed by pressing down the arc plate 3 on the head and back, and the limbs are fixed by two front restraint posts 1 and two rear restraint posts 2. The positions of the first fixing rod 6 and the second fixing rod 7 can be selected according to the size of the animal to fix the rope, making the animal more secure and reliable, with good stability and safety.

[0041] In this embodiment, a moving mechanism is also included. The moving mechanism is mounted on the fixed frame 4 and is used to move the rear restraint post 2 closer to or away from the front restraint post 1.

[0042] In this embodiment, the moving mechanism includes:

[0043] The lead screw 10 has both ends rotatably mounted on the fixed frame 4;

[0044] The slide plate 12 is movably mounted on the lead screw 10. Both ends of the slide plate 12 are fixedly connected to two rear retaining posts 2 respectively. Nuts that cooperate with the lead screw 10 are provided on the slide plate 12.

[0045] Multiple slide rods 8 are symmetrically arranged on both sides of the lead screw 10. Both ends of the slide rods 8 are fixedly connected to the fixing frame 4. Multiple sliders 9 that cooperate with the slide rods 8 are provided on the rear retaining column 2.

[0046] Preferably, the slide bar 8 includes four bars, with two slide bars 8 on each side arranged side by side.

[0047] Handwheel 11 is located on the outside of the fixed frame 4 and is fixedly connected to one end of the lead screw 10.

[0048] In practice, turning the handwheel 11 causes the lead screw 10 to rotate, which in turn causes the slide plate 12 to move back and forth along the lead screw 10, and the slider 9 to slide along the slide bar 8, thereby causing the rear retaining post 2 to move closer to or further away from the front retaining post 1.

[0049] In this embodiment, the first end of the head and back pressing arc plate 3 extends at least partially to the outside of the fixing frame 4 and has an arc-shaped tip, while the second end is provided with a sealing plate.

[0050] In this embodiment, a movable part 5 is provided at the bottom end of the fixing frame 4.

[0051] Preferably, the movable part 5 is a caster wheel with a brake.

[0052] This utility model is small in size and moderate in weight. It has casters for easy movement and brakes for stability and sturdiness. The moving mechanism can move the rear restraint post 2 closer to or away from the front restraint post 1. It is suitable for fixing pigs of different body lengths and can be used for convenient movement and rotation, making it easy for experimental personnel to operate quickly.

[0053] How to use:

[0054] Step 1: The operator lifts the pig onto its back and places it in the area where the head and back are fixed and the limbs are secured. The pig is lying on its back with its legs and limbs in a supine position and is unable to kick or thrash.

[0055] Step 2: Depending on the pig's weight and size, rotate the adjustment handwheel 11 to adjust the distance between the rear restraint post and the front restraint post, so that the front restraint post is positioned about 15cm in front of the pig's forelimbs and the rear restraint post is positioned about 15cm behind the pig's hindlimbs. Select the corresponding fixing rod on the restraint post according to the length of the pig's limbs, and fix the position with ropes. Use hemp rope or cloth strips to fix the pig's limbs, pull the limbs as tight as possible, so that the pig's hindquarters are completely in contact with the head and back, and press them onto the arc plate 3.

[0056] Step 3: Quickly secure the pig with restraint ropes to prevent it from jumping out of the trough if its limbs are not fully tightened, eliminate the forward and backward arching forces, prevent disturbances during the experiment, and ensure it is firmly secured so as not to affect the experimental process or cause injury to the experimenters.

[0057] Step 4: Different types of experiments can be conducted based on the experimental design.

[0058] In practice, depending on the experimental purpose, it can be further selected for use in high-level biosafety laboratories. Its small size makes it convenient for experimental operations such as temperature measurement, blood collection, injection, collection of eye swabs, nasal swabs, anal swabs, anesthesia, dissection, and collection of pathogens.

[0059] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model are included within the protection scope of this utility model.
