Description

Technical Field

[0001] This utility model relates to the field of animal experimental technology, and in particular to a rat restraint for animal experiments. Background Technology

[0002] Animal experiments refer to scientific research conducted in a laboratory using animals to gain new knowledge or solve specific problems in fields such as biology and medicine. Some animal experiments involve rats, requiring the rats to be restrained during the experiment.

[0003] Existing restraint devices typically only restrain the rat's torso. Since rats are too aggressive and difficult to restrain, there is not only a risk of being bitten during the experiment, but it also affects the operation of the animal experiment. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in the prior art, only the rat's torso is fixed, leaving the head on the outside, which poses a risk of bite to the experimenter. Therefore, this invention proposes a rat restraint device for animal experiments.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A rat restraint for animal experiments includes a restraint body with two through ends and multiple sets of clamping plates. One end of each set of clamping plates is rotatably connected to one end of the restraint body. A fastening element is provided on the outer wall of each clamping plate. When the fastening element is activated, the other ends of the multiple sets of clamping plates retract or expand. A head cover is provided at one end of the restraint body, and the other ends of the multiple sets of clamping plates are located inside the head cover.

[0007] To facilitate the setting of the clamping plates, preferably, the main body of the fixture has a cylindrical structure of rotation, and multiple sets of clamping plates are evenly distributed around one end of the main body of the fixture.

[0008] To facilitate experiments on the rat's trunk, a notch is further provided on the outer wall of the other end of the fixation body, and the notch extends along the axial direction of the fixation body.

[0009] In order to limit the rope, preferably, a threading plate with through holes is fixedly provided on the outer wall of the card plate, and the fastening member passes through the through holes on the threading plate in sequence.

[0010] Furthermore, the fastening element includes a rope, one end of which passes through the through holes in the threading plate in sequence, and when the rope is tightened, the other ends of the multiple sets of clamping plates converge with each other.

[0011] Furthermore, the two free ends of the rope are fixedly connected, and the rope is provided with a pig snout buckle for adjusting the tightness.

[0012] Preferably, the end of the card plate away from the main body of the fixture is fixedly provided with a clamping end, the clamping end has an arc-shaped structure, and the card plate is made of stainless steel.

[0013] Preferably, one end of the card plate is rotatably connected to one end of the retainer body via a hinge.

[0014] Preferably, two sets of symmetrically distributed elastic rope loops are fixedly provided on the outer wall of the head cover, and two sets of fixing blocks are fixedly provided on the outer wall of one end of the main body of the fixator. The fixing blocks are symmetrically distributed, and the two sets of fixing blocks are provided with slots. The ends of the elastic rope loops away from the head cover are respectively fitted onto the corresponding slots.

[0015] Furthermore, the headgear is a tubular structure with both ends open, and the headgear is made of transparent plastic.

[0016] Compared with the prior art, this utility model provides a rat restraint for animal experiments, which has the following beneficial effects:

[0017] 1. This rat restraint for animal experiments has multiple sets of clamping plates installed at one end of the restraint body. By tightening the rope, the clamping ends of the plates can be closed to fix the rat's head, preventing the rat from biting the experimenter due to stress. Moreover, putting a head cover over the rat's head can further shield the rat's head and improve the protective effect.

[0018] 2. This rat restraint device for animal experiments uses a threaded plate fixed to the outer wall of the clamping plate. The rope is passed through the through hole in the threaded plate. On the one hand, when the rope is tightened, multiple clamping plates can be closed as synchronously as possible, improving the fixation effect on the rat's head. On the other hand, it can prevent the rope from slipping off the clamping plate and becoming unusable. Moreover, the tightness of the rope is adjusted by using a pig nose buckle, which can achieve quick fixation or loosening, improving the effectiveness of use.

[0019] The parts of this device not described herein are the same as or can be implemented using existing technology. This utility model has multiple sets of clamping plates rotatably installed at one end of the main body of the fixation device. By tightening the rope, the clamping ends of the clamping plates can be retracted to fix the rat's head, preventing the rat from biting the experimental personnel due to stress. Moreover, by putting the head cover over the rat's head, the rat's head can be further shielded, improving the protective effect. Attached Figure Description

[0027] Example:

[0028] Reference Figures 1-4A rat restraint for animal experiments includes a restraint body 1 extending through both ends. The restraint body 1 can have a rectangular or circular cross-section. Here, we design the restraint body 1 as a cylindrical structure of revolution, and multiple sets of clamping plates 2. Each set of clamping plates 2 has one end rotatably connected to one end of the restraint body 1. The clamping plates 2 are evenly distributed circumferentially on one end of the restraint body 1. There are two to ten sets of clamping plates 2; here, eight sets are preferred. A fastening element is provided on the outer wall of the clamping plates 2. When the fastening element is activated, the other ends of the multiple sets of clamping plates 2 either close or expand. That is, by binding or loosening the fastening element, the rat can be restrained. To fix or relax the rat's head, the other ends of the multiple sets of clamps 2 are brought closer together, preventing the rat from biting the experimenter due to stress. At this time, the rat's torso is located inside the main body 1 of the restraint device. The rat's abdomen or back can be tested through the notch 101 on the main body 1. A head cover 4 is provided at one end of the main body 1. The other ends of the multiple sets of clamps 2 are located inside the head cover 4. When the other ends of the clamps 2 are closed to fix the rat's head, both the other ends of the clamps 2 and the rat's head are located inside the head cover 4, which can further shield the rat's head, prevent it from biting the experimenter, and improve the protective effect.

[0029] In use, multiple sets of clamping plates 2 are rotated at one end of the main body 1 of the fixture. By tightening the rope 3, the clamping ends of the clamping plates 2 can be closed to fix the rat's head and prevent the rat from biting the experimenter due to stress. Moreover, putting the head cover 4 on the rat's head can further cover the rat's head and improve the protective effect. By fixing the threading plate 202 on the outer wall of the clamping plate 2, the rope 3 is passed through the through hole on the threading plate 202. On the one hand, when the rope 3 is tightened, the multiple sets of clamping plates 2 can be closed as synchronously as possible to improve the fixation effect on the rat's head. On the other hand, it can prevent the rope 3 from slipping off the clamping plate 2 and causing it to become unusable. In addition, the tightness of the rope 3 is adjusted by using the pig nose buckle 301, which can achieve quick fixation or loosening and improve the use effect.

[0030] Reference Figure 1 , Figure 3 and Figure 4A notch 101 is provided on the outer wall of the other end of the fixation body 1, and the notch 101 extends along the axial direction of the fixation body 1. The notch 101 does not penetrate the fixation body 1. The inner diameter of the fixation body 1 and the head cover 4 is in the range of five to seven centimeters. Here, we prefer that the inner diameter of the fixation body 1 is seven centimeters and the inner diameter of the head cover 4 is five centimeters. The length of the fixation body 1 is in the range of fifteen to twenty centimeters, preferably fifteen centimeters. The length of the notch 101 is two to five centimeters shorter than the length of the fixation body 1. In use, by providing the notch 101 on the fixation body 1, it is convenient to conduct experiments on the rat's torso. When it is necessary to conduct experiments on the rat's abdomen, the rat's abdomen can be placed inside the notch 101. Similarly, when it is necessary to conduct experiments on the rat's back, the rat's back needs to be placed inside the notch 101.

[0031] Reference Figure 4 A threading plate 202 with through holes is fixedly installed on the outer wall of the card plate 2. The fastening members are passed through the through holes on the threading plate 202 in sequence. In use, by fixing the threading plate 202 on the outer wall of the card plate 2, it is not only convenient to limit the fastening members, but also to improve the gathering effect of the card plate 2.

[0032] Reference Figure 4 The fastening device can be a cable tie or elastic band, but here we prefer a rope 3. One end of the rope 3 is passed through the through hole on the threading plate 202. When the rope 3 is tightened, the other ends of the multiple sets of clamping plates 2 are pulled together. That is, by tightening the two free ends of the rope 3, the other ends of the clamping plates 2 can be pulled together to fix the rat's neck. When fixing, tie a slipknot at the appropriate position on the two free ends. While ensuring reliable fixation of the rat's head, it should be kept able to breathe smoothly to improve the user experience.

[0033] Reference Figure 4 The two free ends of the rope 3 are fixedly connected, and a pig nose buckle 301 for adjusting the tightness is provided on the rope 3. In use, by setting the pig nose buckle 301 on the rope 3, not only can the tightness of the rope 3 be quickly adjusted, but the tightness of the rope 3 can also be adjusted as precisely as possible to improve the fixing effect.

[0034] Reference Figure 3 and Figure 4 A clamping end is fixedly provided on the end of the clamping plate 2 away from the main body 1 of the fixator. The clamping end has an arc-shaped structure, and the material of the clamping plate 2 is stainless steel. When in use, by fixing the clamping end with an arc-shaped structure on the clamping plate 2, not only can the fixation effect on the rat's neck be improved, but also the discomfort of the rat's neck can be reduced, thus improving the use effect.

[0035] Reference Figure 4One end of the clamping plate 2 is rotatably connected to one end of the fixture body 1 via a hinge 201. This design is simple in structure and easy to manufacture. Here, we prefer the hinge 201 to be an automatic spring-loaded hinge 201, which is existing technology. Simply put, the automatic spring-loaded hinge 201 has a torsion spring inside. Under the elastic force of the torsion spring, the clamping plate 2 can automatically unfold. That is, when the clamping plate 2 is no longer restrained by the rope 3, it can automatically unfold outward, which facilitates the fixation of the rat. Especially when pulling the rat by the tail into the fixture body 1, multiple clamping plates 2 are in the unfolded state, which can reduce interference when traction is applied to the rat. After the rat's torso is pulled into the fixture body 1, the rope 3 is tightened to close the clamping plate 2, thus fixing the rat's neck. After the experiment is completed, the rope 3 is loosened, and the clamping plate 2 unfolds automatically. At this time, the rat's tail can be pushed out of the fixture body 1.

[0036] Reference Figures 1-3 Two sets of symmetrically distributed elastic rope loops 401 are fixedly installed on the outer wall of the head cover 4. Two sets of fixing blocks 5 are fixedly installed on the outer wall of one end of the main body 1 of the fixator. The fixing blocks 5 are symmetrically distributed and have slots 501 on the two sets of fixing blocks 5. The ends of the elastic rope loops 401 away from the head cover 4 are respectively fitted into the corresponding slots 501. In use, by fixing the elastic rope loops 401 on the head cover 4 and fixing the fixing blocks 5 on the outer wall of the main body 1 of the fixator, and opening slots 501 on the fixing blocks 5, after the clamping plate 2 is fixed to the rat's neck, the head cover 4 is put on the rat's head, and then the elastic rope loops 401 are put into the slots 501. This can prevent the head cover 4 from falling off and can also cover the rat's head, improving the protective effect.

[0037] Reference Figures 1-3 Here, we designed the head cover 4 as a tubular structure with both ends open, and the head cover 4 is made of transparent plastic. When using it, by choosing transparent plastic as the material of the head cover 4, it is convenient to observe the rat's head, thereby making it easier to react and improving the effect of use.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
