Description

Technical Field

[0001] This utility model belongs to the technical field of live pig experimental equipment, specifically relating to a support experimental frame for live pig experiments. Background Technology

[0002] With the development of science and technology, mice, rats, dogs, pigs and other laboratory animals have been widely used in many aspects of biomedical research, such as skin burns, tumors, immunity, cardiovascular diseases, malformations, human tissue donation, genetic diseases, nutritional metabolic diseases, and new drug metabolism research.

[0003] Currently, the restraint of canine and pig laboratory animals used in simulation experiments is generally achieved by rope binding, but there is no better method of restraint. Sometimes, tight binding can affect the breathing and normal physiological limits of canine and pig laboratory animals, while loose binding can cause them to escape midway. During the experiment, the inability to securely fix the limbs of the laboratory animals, as well as their turning over and twisting of their necks, can also affect the experimental process and results. Moreover, the failure to promptly dispose of the feces of the laboratory animals will cause pollution of the experimental environment. Such problems seriously affect the progress of scientific research.

[0004] To address this, Chinese invention patent CN109223240A discloses a restraint device for canine and pig laboratory animals, comprising two upright supports fixed to the front end of a movable base plate and two movable upright supports at the rear end in an adjustment groove. The upright supports have several adjustment holes for mounting movable hooks to hold animal stretchers with forelimb and hindlimb fixation holes. The animal stretchers have fixed drainage holes for ventilation and position adjustment, and an animal excretion port at the rear. The two front upright supports are also equipped with neck clamping components to hold the necks of canine and pig laboratory animals and keep their upper bodies fixed. The movable base plate can change its width by altering the relative positions of its right and left base plates to accommodate canine and pig laboratory animals of different body shapes and sizes. The movable base plate has movable wheels with foot brakes for easy movement and locking.

[0005] This approach has solved the problem of animal fixation to some extent, but it still has at least the following problems: for example, the equipment operation process is cumbersome, there is a lot of preparation work, and the device needs to be adapted to each new animal.

[0006] Therefore, there is an urgent need for a more convenient fixation device that can be directly applied to laboratory animals of different sizes. Utility Model Content

[0007] The purpose of this invention is to provide a support frame for live pig experiments, so as to partially alleviate or solve the above-mentioned problems and improve the efficiency of the experiment.

[0008] To solve the aforementioned technical problems, the present invention specifically adopts the following technical solution:

[0009] A support frame for live pig experiments includes a mounting column, a support plate, and a fixing plate. The support plate has first mounting holes on its four sides, and the fixing plate has second mounting holes on its four sides corresponding to the first mounting holes. The fixing plate has multiple sets of fixing holes of different sizes, and first fences are rotatably installed on the two side walls along the length of the fixing plate.

[0010] When the first fence is in the locked state, the first fence and the fixing plate together form a fixed space;

[0011] It also includes a lifting mechanism for driving the support plate or the fixed plate to rise and fall;

[0012] When the mounting column passes through the first mounting hole and the second mounting hole in sequence, the fixing plate is located above the support plate. At least one of the support plate and the fixing plate can be raised and lowered on the mounting column, so that the live pig on the fixing plate can switch between a suspended and non-suspended state.

[0013] As an improvement, a buffer plate is also provided at the first end of the fixed plate, and a second fence is rotatably provided on the two side walls of the buffer plate along its length; when the second fence is in the locked state, the second fence and the buffer plate together form a buffer channel.

[0014] As an improvement, the bottom of the buffer plate is provided with at least one support column.

[0015] As an improvement, the support plate is fixedly connected to the mounting column, and the fixing plate is movably mounted on the mounting column.

[0016] As an improvement, the fixing plate is fixedly connected to the mounting column, and the support plate is movably mounted on the mounting column.

[0017] As an improvement, the support plate and the fixing plate are respectively movably mounted on the mounting column, and the lifting mechanism includes a first sub-lifting mechanism for driving the support plate to rise and fall on the mounting column, and a second sub-lifting mechanism for driving the fixing plate to rise and fall on the mounting column.

[0018] As an improvement, the lifting mechanism is located at the bottom of the support plate, with the first end of the lifting mechanism resting on the ground and the second end resting on the bottom of the support plate.

[0019] As an improvement, a clamp for fixing the head of the live pig is movably provided at the first end of the fixing plate.

[0020] As an improvement, a flexible protective sleeve is provided on the fixing hole.

[0021] As an improvement, a pressure sensor is provided on the first surface of the support plate, and the pressure sensor is electrically connected to the lifting mechanism.

[0022] The principle and beneficial technical effects of this utility model are as follows:

[0023] This application provides an automated live pig support experimental frame. First, when the live pig stands on the fixed plate and its four feet fall into the fixed holes on the fixed plate that match the size of the pig's body, the fixed plate or the support plate is raised or lowered, or both are raised or lowered at the same time, so that the distance between the fixed plate and the support plate increases, thereby causing the pig's feet to suspend in the air and lose their footing, thus preventing the pig from struggling and shaking during the experiment.

[0024] Furthermore, before the live pig enters the device, the fixing holes are sealed, and fences are installed on both sides of the fixing plate and the buffer plate. This creates a safe environment for the pig, allowing it to enter the experimental rack on its own. Once the pig enters the experimental rack, the fences can be lowered to expose the pig's body, facilitating ultrasound or CT scans and other operations, thus enabling more experimental projects.

[0025] In addition, while providing stable clamping for live pigs, this device also ensures the pigs' comfort (the fixing holes are located at the base of the pig's four legs, so that the pig's lower abdomen is in close contact with the upper surface of the fixing plate, and the fixing plate can provide large-area support for the live pig and distribute the force evenly), thus facilitating long-term (30 minutes and above) experiments on multiple parts of the live pig without anesthesia.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0037] In this document, suffixes such as "module," "component," or "unit" used to denote elements are used solely for the purpose of illustrative purposes and have no specific meaning in themselves. Therefore, "module," "component," or "unit" can be used interchangeably. In this document, terms such as "upper," "lower," "inner," "outer," "front," "rear," "one end," and "the other end," indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are used only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0038] In this document, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; it can also refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. In this document, "multiple" means two or more, that is, it includes two, three, four, five, etc.

[0039] The implementation examples are basically as follows Figures 1-8 As shown:

[0040] See Figures 1-5 This utility model provides a support experimental frame for live pig experiments, including a mounting column 1, a support plate 2 and a fixing plate 3. The support plate 2 is provided with first mounting holes on its four sides, and the fixing plate 3 is provided with second mounting holes corresponding to the first mounting holes on its four sides. The fixing plate 3 is provided with multiple sets of fixing holes 301 of different sizes. The two side walls along the length of the fixing plate 3 are respectively provided with first fences 4.

[0041] When the first fence 4 is in the locked state, the first fence 4 and the fixing plate 3 together form a fixed space; when the first fence 4 is in the unlocked state, the first fence 4 is located below the fixing plate 3, exposing the fixing plate 3, or the first fence 4 can be removed from the fixing plate, thereby exposing the body part of the live pig.

[0042] It also includes a lifting mechanism 5 for driving the support plate 2 or the fixed plate 3 to rise and fall;

[0043] When the mounting post 1 passes through the first mounting hole and the second mounting hole in sequence, the fixing plate 3 is located above the support plate 2, and at least one of the support plate 2 and the fixing plate 3 can be raised and lowered on the mounting post 1.

[0044] The first end of the fixed plate 3 is also provided with a buffer plate 6, and the two side walls of the buffer plate 6 in the length direction are respectively rotatably provided with second fences 7; when the second fences 7 are in the locked state, the second fences 7 and the buffer plate 6 together form a buffer channel; when the second fences 7 are in the unlocked state, the second fences 7 are located below the buffer plate 6 and expose the buffer plate 6, or the second fences 7 can be removed from the buffer plate.

[0045] In some embodiments, the fixing holes 301 are densely arranged so that pig feces can fall onto the support plate 2 through the fixing holes 301, preventing feces from accumulating on the fixing plate 3 and interfering with the experiment. At the same time, it also ensures that the pig's limbs can easily fall into the fixing holes 301 while walking on the fixing plate 3, thus improving the efficiency of the experiment.

[0046] In some embodiments, the first fence 4 and the second fence 7 may be rotatably connected to the fixing plate 3 via hinges, and the connecting part is provided with a latch. When the first fence 4 or the second fence 7 is rotated to a specified angle, it is fixed by the latch.

[0047] In some embodiments, the bottom of the buffer plate 6 is provided with at least one support column 8.

[0048] In some specific embodiments, there are a total of four support columns 8, which are evenly distributed at the four corners of the buffer plate 6.

[0049] In some embodiments, the support plate 2 is fixedly connected to the mounting column 1, and the fixing plate 3 is movably disposed on the mounting column 1.

[0050] In other embodiments, see Figures 1-5 The fixing plate 3 is fixedly connected to the mounting column 1, and the support plate 2 is movably disposed on the mounting column 1.

[0051] In some other embodiments, see Figures 6-8 The support plate 2 and the fixing plate 3 are respectively movably mounted on the mounting column 1. The lifting mechanism 5 includes a first sub-lifting mechanism 501 for driving the support plate 2 to rise and fall on the mounting column 1, and a second sub-lifting mechanism 502 for driving the fixing plate 3 to rise and fall on the mounting column 1. By lifting the fixing plate, the height of the live pig can be adjusted to accommodate ultrasound equipment, CT scanning equipment, etc., of different heights, and also to accommodate operators of different heights.

[0052] For ease of installation, the lifting mechanism 5 (or the first sub-lifting mechanism) used to lift the support plate 2 can be a lifting platform, while the lifting mechanism 5 (or the second sub-lifting mechanism) used to lift the fixed plate 3 can be a lifting rod set around the fixed plate 3. Of course, it can also be other lifting structures that can lift the fixed plate 3 and the support plate 2.

[0053] In some embodiments, the lifting mechanism 5 is disposed at the bottom of the support plate 2, with the first end of the lifting mechanism 5 resting on the ground and the second end of the lifting mechanism 5 resting on the bottom of the support plate 2, such as a lifting platform.

[0054] In some embodiments, a clamp for fixing the head of the live pig is movably provided at the first end of the fixing plate 3. After the limbs of the live pig are fixed in the fixing holes 301, the position and angle of the clamp can be adjusted so that it fits around the pig's neck, which can further improve the fixing effect on the pig.

[0055] In some embodiments, a flexible protective sleeve is provided on the fixing hole 301. The protective sleeve can effectively protect the pig's legs and prevent the pig's legs from being worn by the rigid fixing plate 3 during the struggle.

[0056] In some embodiments, a pressure sensor is provided on the first surface of the support plate 2, and the pressure sensor is electrically connected to the lifting mechanism 5. When the pig's foot enters the fixing hole 301, the pressure sensor transmits a signal to the lifting mechanism 5, and the lifting mechanism 5 automatically raises and lowers to suspend the pig, making the process faster and more efficient.

[0057] In some embodiments, the fixing plate, support plate, buffer plate, first fence, and second fence are all made of rigid materials, such as stainless steel plates, to ensure that the experimental frame has high strength.

[0058] In practical use, first, restore the support frame to its initial position. At this time, the support plate is tightly attached to the bottom of the fixed plate. The first and second fences are folded upwards. The first fence and the fixed plate enclose a fixed space with a closed bottom and sides and an open top and front and back. The second fence and the buffer plate enclose a buffer channel similar to the fixed space. The first end of the fixed space and the second end of the buffer channel are seamlessly connected to form an integral channel. Then, the live pig enters the buffer channel and the fixed space sequentially from the second end of the buffer channel. After the live pig enters the fixed space, its limbs fall into the corresponding fixed holes. The lifting mechanism drives the fixed plate or support plate to rise or fall, or simultaneously drives the fixed plate and support plate to rise or fall, thereby separating the fixed plate and support plate, so that the pig's legs are suspended in the air (see [reference]). Figure 5 Then, the first fence on both sides was lowered to expose the pig's body for the experiment.

[0059] The support frame with the above structure allows live pigs to adapt to the environment through a buffer channel, preventing them from being startled and ensuring that they can move forward independently into the fixed space. Once the pig's limbs fall into the fixing holes, they can be firmly fixed in place. At the same time, the suspended design, combined with the clamps at the neck of the fixing column, can effectively prevent the pig from struggling and shaking during the experiment. In addition, the fixing holes are located at the base of the pig's four legs, which can not only securely fix the pig, but also greatly improve the pig's comfort (at this time, the pig's lower abdomen is close to the upper surface of the fixing plate, and the fixing plate can provide large-area support for the pig with even force). This makes it convenient to conduct long-term (30 minutes and above) experiments on multiple parts of the pig without anesthesia.

[0060] In summary, this application provides a relatively automated support experimental frame capable of stably holding pigs.
