Description

Technical Field

[0001] This utility model relates to the field of medical experiments, specifically to a device for fixing experimental animals. Background Technology

[0002] Animal experiments refer to scientific research conducted in a laboratory using animals to obtain new knowledge or solve specific problems in fields such as biology and medicine. One of the most important aspects of animal experiments is how to restrain the animals. Depending on the experiment being conducted, the method of restraint varies. Sometimes the animals need to be positioned with their backs facing up, and sometimes with their bellies facing up. The key is to restrain the animals in a way that allows for experiments to be conducted from multiple angles.

[0003] Existing animal restraint devices, such as the one disclosed in patent number CN208823040U, utilize a base and a suspended operating table, allowing researchers to simultaneously perform head and back experiments and simple abdominal injections on animals. Simultaneously, by incorporating support rods, a seat, and rotating clamps, the operating table can be vertically flipped, turning the animal's abdomen upwards for more complex abdominal dissection experiments. While this device allows for both head and back and abdominal experiments after animal restraint, its complex structure can make animal rotation difficult. Therefore, developing a restraint device that allows for quick and convenient animal rotation while simultaneously restraining the animal, enabling the next experiment to proceed as soon as possible, is a problem that needs to be solved. Summary of the Invention

[0004] In order to solve the problems existing in the prior art, the present invention provides an experimental animal restraint device, which aims to solve the problem that the existing animal restraint devices cannot quickly and conveniently turn the animal over while restraining it.

[0005] An experimental animal restraint device includes a box and an operating panel. One end of the operating panel is hinged to the box via a pin, and the other end of the operating panel is detachably connected to the box. The operating panel has a through groove, within which a telescopic frame is slidably connected. Preferably, the box is made of transparent material, and its edge has a groove. The edge of the operating panel matches the groove to support the operating panel. The operating panel is first detachably connected to one end of the box. Then, the experimental animal is fixed to the operating panel with its back facing upwards. After experiments on the back or limbs of the experimental animal are completed, the operating panel is flipped over and detachably connected to the other end of the box. The experimental animal is then placed inside the box and supported by the bottom of the box. The telescopic frame is then opened to expose the abdomen of the experimental animal, allowing for experiments to be performed on the abdomen.

[0006] Preferably, one end of the telescopic frame is fixedly connected to one end of the through groove, and the through groove is provided with sliding grooves on both sides. The sliding grooves are slidably connected to the two sides of the telescopic frame, making it easier to move the telescopic frame.

[0007] Preferably, the telescopic frame is a scissor-type telescopic frame, which occupies less space when folded and can fully expose the animal's abdomen.

[0008] Preferably, the telescopic frame is slidably connected to the slide groove via a support rod, and the two ends of the telescopic frame are slidably connected to the two ends of the support rod via hinged sliders. The middle of the telescopic frame is hinged to the middle of the support rod, making the telescopic frame more stable when it is extended.

[0009] Preferably, the bottom of the box is provided with multiple adjustment plates, one end of which passes through the box and a handle is provided at the end of the adjustment plate that passes through the box. The adjustment plates can be pulled out of the box or put into the box according to the size of the experimental animal, thereby adjusting the size of the space inside the box. This ensures that the animal can be stably supported inside the box after the operation plate is flipped, which is convenient for the next step of the experiment.

[0010] Preferably, the operating plate is provided with a fixing component, the operating plate and the fixing component are detachably connected, the surface of the operating plate is a hook and loop fastener, and the fixing component is a hook and loop fastener, so that when the animal is placed on the operating plate, the hook and loop fastener can be directly attached to fix the animal.

[0011] Preferably, the fixing components include a head fixing component, a tail fixing component, and limb fixing components. The head fixing component is located at one end of the through groove, the tail fixing component is located at the other end of the through groove, and the limb fixing components are located on both sides of the through groove. The separate fixing makes the experimental animal more secure.

[0012] Preferably, the end of the operating panel away from the pin is provided with an opening, which makes it convenient to hold the opening by hand to flip the operating panel.

[0013] The beneficial effects of this invention include:

[0014] When conducting experiments on the animal's back, the animal is fixed to the operating board. If the abdomen needs to be operated on after the back is completed, the operating board is flipped over using a pin, and the telescopic frame on the operating board is moved to expose the animal's abdomen, allowing for operation on the abdomen. The whole process is simple and quick, requiring no complicated operations, thus improving experimental efficiency. Furthermore, the size of the box can be adjusted according to the animal's size, ensuring that the animal is stably supported even after being flipped over, facilitating the operator to carry out the next step of the experiment.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0021] Example 1

[0022] like Figure 1 As shown, an experimental animal restraint device in this embodiment includes a box 4 and an operating plate 1. One end of the operating plate 1 is hinged to the box 4 via a pin 2, and the other end of the operating plate 1 is detachably connected to the box 4. The operating plate 1 has a through groove, and a telescopic frame 3 is slidably connected in the through groove. The box 4 is made of transparent material, and the edge of the box 4 has a groove 41. The edge of the operating plate 1 matches the groove 41 to support the operating plate 1. The operating plate 1 is first detachably connected to one end of the box 4. Then, the experimental animal is fixed to the operating plate 1 with its back facing upward. After the experiment on the back or limbs of the experimental animal is completed, the operating plate 1 is flipped over and detachably connected to the other end of the box 4. At this time, the experimental animal is placed inside the box 4 and supported by the bottom of the box 4. Then, the telescopic frame 3 is opened to expose the abdomen of the experimental animal, and the corresponding experiment can be performed on the abdomen.

[0023] One end of the telescopic frame 3 is fixedly connected to one end of the through groove. The through groove is provided with sliding grooves on both sides, and the sliding grooves are slidably connected to the two sides of the telescopic frame 3, making it easier to move the telescopic frame 3.

[0024] The telescopic frame 3 is a cross-scissor type telescopic frame 3, which occupies less space when folded and can fully expose the animal's abdomen.

[0025] The telescopic frame 3 is slidably connected to the slide groove via the support rod 6. The two ends of the telescopic frame 3 are slidably connected to the two ends of the support rod 6 via hinged sliders 61. The telescopic frame 3 is hinged to the middle of the support rod 6, making the telescopic frame 3 more stable when it is extended.

[0026] The bottom of the box 4 is provided with multiple adjustment plates 5. One end of each adjustment plate 5 passes through the box 4, and the end of each adjustment plate 5 passing through the box 4 is provided with a handle 51. The adjustment plates 5 can be pulled out of the box 4 or put into the box 4 according to the size of the experimental animal, thereby adjusting the size of the space inside the box 4. This allows the animal to be stably supported inside the box 4 after the operation plate 1 is flipped, which is convenient for the next step of the experiment.

[0027] The operating panel 1 is provided with a fixing component 11. The operating panel 1 and the fixing component 11 are detachably connected. The surface of the operating panel 1 is a hook and loop fastener, and the fixing component 11 is a hook and loop fastener. When an animal is placed on the operating panel 1, the hook and loop fastener can be directly attached to fix the animal in place.

[0028] The fixation component 11 includes a head fixation component, a tail fixation component, and limb fixation components. The head fixation component is located at one end of the through groove, the tail fixation component is located at the other end of the through groove, and the limb fixation components are located on both sides of the through groove. The separate fixation makes the experimental animal more secure.

[0029] The operating plate 1 has an opening 12 at the end away from the pin 2, which makes it convenient to hold the opening 12 by hand to flip the operating plate 1.

[0030] Specific implementation process: First, place the experimental animal back-up on the operating board 1, and then use Velcro to attach the animal's limbs and head to the operating board 1 for fixation. Next, the operator performs the corresponding experimental operations on the animal. After this stage of operation, the animal needs to be turned over. At this time, hold the opening 12 of the operating board 1 with your hand and use the pin 2 to turn the operating board 1 over. Then, the operating board 1 fits into the groove 41 at the other end of the box 4 to fix the operating board 1. At this time, observe through the transparent box 4 whether the experimental animal inside the box 4 is in contact with the adjustment plate 5, that is, whether it is stably supported. If the distance between the experimental animal and the adjustment plate 5 is too large, add another adjustment plate 5 to the box 4. If the experimental animal is squeezed at this time, hold the handle 51 of the adjustment plate 5 and pull out an adjustment plate 5 from the box 4 until the experimental animal is in a suitable position. Then, move the telescopic frame 3 of the operating board 1 to retract it to one side, exposing the experimental animal's abdomen, and then perform the corresponding experimental operations on the experimental animal's abdomen.

[0031] Example 2

[0032] like Figure 1As shown, the difference between this embodiment and embodiment 1 is that the operation panel 1 is provided with multiple sets of holes, and the fixing component 11 is a cable tie. After passing the cable tie through the holes, the limbs and head of the experimental animal are tied and fixed.

[0033] The embodiments described above merely illustrate specific implementation methods of this application, and while the descriptions are detailed and specific, they should not be construed as limiting the scope of protection of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the technical solution of this application, and these modifications and improvements all fall within the scope of protection of this application.
