Technical Field

[0001] The utility model relates to the field of experimental instruments, and particularly relates to an experimental animal fixator. Background Art

[0002] Mouse tail vein injection is often used in drug screening and acute toxicity tests. Traditional mouse tail vein injection fixators are mostly cylindrical with an opening at one end that can be closed and the other end that can be ventilated. The main principle of use is to stuff the mouse into the cylinder during injection, close one end of the cylinder, and expose the mouse's tail through the opening at this end for tail vein injection. Although the above fixator device can achieve the expected purpose during actual use, there are still some problems that need to be improved. For example, since the mouse's head is fixed in a closed state, the mouse will struggle during binding, which will cause the tail to shake and affect injection. Moreover, the commonly used fixator restricts other operations of the mouse, such as blood pressure measurement.

[0003] The "Visual Mouse Tail Vein Injection Fixator" with the publication number CN 219557639 U has given a fixation solution for mice.

[0055] Please refer to Figures 1 to 5, this embodiment provides an experimental animal fixator, which includes a main body 1, two groups of first binding straps 2, a first fixing component 3, four groups of second binding straps 4, and a second fixing component 5. The main body 1 has a first side 11 and a second side 12, and the first side 11 and the second side 12 are arranged opposite to each other; the two groups of first binding straps 2 include at least one first binding strap 2. One end of the first binding strap 2 is connected to the main body 1 and is arranged between the first side 11 and the second side 12. The other end of the first binding strap 2 is suspended outward, and the first binding strap 2 is an elastic band; the first fixing component 3 includes a first fixing member 31 and a second fixing member 32. The first fixing member 31 is arranged at the outwardly suspended end of the first binding strap 2, and the second fixing member 32 is arranged on the main body 1 and is arranged at a first preset position. The first fixing member 31 and the second fixing member 32 are detachably connected; the four groups of second binding straps 4 include two second binding straps 4, and the two second binding straps 4 are arranged in parallel on the second side 12, and the other ends of the second binding strap group 4 are suspended outward; the second fixing component 5 includes a third fixing member 51 and a fourth fixing member 52. The number of the third fixing members 51 corresponds to the number of the second binding straps 4. The third fixing member 51 is arranged at the outwardly suspended end of the second binding strap 4, and the fourth fixing member 52 is arranged on the main body 1 and is arranged at a second preset position. The third fixing member 51 and the fourth fixing member 52 are detachably connected;

[0056] The main body 1 can be placed in a winding position. When the main body 1 is placed in the winding position, the first side 11 of the main body 1 approaches the neck of the experimental animal and winds around to wrap the torso of the experimental animal inside the main body 1. The first binding strap 2 winds around the periphery of the main body 1 and then fixes the experimental animal once through the first fixing member 31 and the second fixing member 32. The second binding strap 4 bends from the second side 12 towards the first side 11 and fixes the experimental animal twice through the third fixing member 51 and the fourth fixing member 52.

[0057] In this embodiment, the main body 1 can be a flexible sheet structure formed by weaving fabric or organic non-metallic materials. Optionally, the main body 1 formed by weaving elastic materials can also have the ability of elastic deformation to better fit the outer surface of the experimental animal. In this embodiment, the main body 1 is quadrilateral, and in other embodiments, it can also be pentagonal, hexagonal, or a special shape with an arc surface. For the convenience of description, the sides of the main body 1 are divided into a first side 11, a second side 12, a third side 13, and a fourth side 14 described later. Among them, the first side 11 and the second side 12 are arranged opposite to each other. When the main body 1 is in the winding position, the first side 11 is close to the head of the experimental animal, and the second side 12 is close to the tail of the experimental animal. That is to say, the third side 13 and the fourth side 14 are parallel to the placement direction of the trunk of the experimental animal. Then, when binding the experimental animal, the experimental animal can be placed on the main body 1 laid flat first, and then the third side 13 of the experimental animal and the main body 1 can be pinched, and it is wound along the trunk part of the experimental animal until the fourth side 14 to realize the wrapping of the experimental animal by the main body 1. Optionally, the experimental animal can be a rabbit, a laboratory rat, a laboratory mouse, etc. Figures 1 to 5 Taking the laboratory rat as an example for illustration.

[0058] Furthermore, there is a first binding strap 2 between the first side 11 and the second side 12 of the main body 1. The first binding strap 2 can be detachably connected to the main body 1, or the first binding strap 2 can also be directly connected to the main body 1. The specific direct connection method is: one end of the first binding strap 2 is connected to the main body 1, and the other end of the first binding strap 2 extends outward. When the main body 1 is in the winding position, the first binding strap 2 can be grasped by hand to further wind around the periphery of the main body 1 to achieve the primary fixation of the experimental animal. For the convenience of the user's single-handed operation, a first fixing member 31 is also provided at the end of the first binding strap 2 that extends outwardly and is suspended. The second fixing member 32 is provided on the main body 1, specifically at a first preset position. Here, the first preset position can be the position where the user needs to further fix during binding. For example, if the laboratory rat needs to be further fixed in the abdominal area, the first preset position corresponds to the position of the abdominal area of the laboratory rat on the main body 1. The first fixing member 31 and the second fixing member 32 are detachably connected, and the first fixing member 31 and the second fixing member 32 can be configured as a mother-and-son buckle, a magic tape, a button and a buttonhole, etc.

[0059] Please refer to Figure 2 and Figure 3 In some embodiments, the number of the fourth fixing members 52 is two, symmetrically arranged at the second preset position of the main body 1, and one fourth fixing member 52 is detachably connected to one third fixing member 51.

[0060] This embodiment further includes a second binding strap 4, which is arranged on the second side 12. The second side 12 is close to the tail of the experimental animal. The number of the second binding straps 4 is two, which are respectively arranged on the second side 12. Preferably, the second binding straps 4 are symmetrically arranged on the second side 12 with the central axis of the body 1 as the reference. The outwardly suspended end of the second binding strap 4 is further provided with a third fixing member 51, and a fourth fixing member 52 is also arranged on the body 1. The fourth fixing member 52 is detachably connected to the third fixing member 51. It can be understood that the number of the fourth fixing members 52 here can be one, and the fourth fixing member 52 is connected to the two third fixing members 51 at the same time; the number of the fourth fixing members 52 can also be two, and one fourth fixing member 52 is connected to one third fixing member 51. It can be understood that the second preset position is the middle part of the body 1, and its specific position can be determined according to the size of the body 1. When connecting, the binding method of the second binding strap 4 can also be adjusted according to actual needs, such as Figure 4 and Figure 5 shows that the second binding strap 4 is in a cross-fixed form. This method can better fix the tail of the experimental animal. Especially when performing intravenous injection on rats, the binding method of the second binding strap 4 can fix the two lower limbs of the rat in the body 1, and only the tail extends out between the two second binding straps 4 and is exposed outside, which is convenient for the user to operate. At the same time, in this state, the experimental rat is in a stable mood and the tail will not move randomly, reducing the operation difficulty of the user's injection.

[0061] In this embodiment, the body 1 can be placed in the winding position. When the body 1 is placed in the winding position, the first side 11 of the body 1 is close to the neck of the experimental animal and winds around to wrap the torso of the experimental animal in the body 1. The first binding strap 2 winds around the periphery of the body 1 and then fixes the experimental animal once through the first fixing member 31 and the second fixing member 32. The second binding strap 4 bends from the second side 12 towards the first side 11 and fixes the experimental animal twice through the third fixing member 51 and the fourth fixing member 52. The tail of the experimental animal protrudes from the second side 12 and between the two second binding straps 4 to the outside. Since the head of the experimental animal protrudes from the first side 11, and the body 1 is made of a soft material, the first binding strap 2 is an elastic band wrapped around the outside of the body 1, and the second binding strap 4 is also fixed on the outside of the body 1. Therefore, the experimental animal will not be squeezed during the binding process. In this way, the experimental animal is in a calm state and the tail will not shake, so intravenous injection operations can be performed. Moreover, since the head and neck of the experimental animal are outside the first side 11, the experimental animal can also perform blood measurement, etc. Since the entire device is made of flexible materials, the user can quickly bind and fix the experimental animal without involving the screwing operation of hard parts such as screws, improving the use convenience and thus the binding efficiency.

[0062] Please refer toFigures 1 to 5 , in some embodiments, it further includes a third binding strap 6 and a third fixing assembly 7. The third binding strap 6 is disposed on the first side 11, and the third binding strap 6 can drive the first side 11 to contract; the third fixing assembly 7 includes a fifth fixing member 71 and a sixth fixing member 72. The fifth fixing member 71 and the sixth fixing member 72 are respectively disposed at two ends of the first side 11, and the fifth fixing member 71 and the sixth fixing member 72 are detachably connected.

[0063] Please refer to Figure 1 , Figure 4 and Figure 5 , in some embodiments, the third binding strap 6 is an elastic band, and the third fixing assembly 7 is a snap fastener or a magic tape.

[0064] This embodiment further includes a third binding strap 6, and the third binding strap 6 is disposed at the first side 11. Specifically, the third binding strap 6 can be disposed at the first side 11 by sewing. For example, when the third binding strap 6 is an elastic band, it can be directly sewn to the first side 11 to drive the first side 11 to automatically contract. When the body 1 is in the winding position, the third binding strap 6 can drive the first side 11 to generate elastic deformation to adapt to the neck sizes of experimental animals with different volumes. The third fixing assembly 7 is used to keep the third binding strap 6 and the first side 11 always in close contact with the necks of experimental animals. Here, the third fixing assembly 7 can be a snap fastener or a magic tape, and this embodiment does not limit this.

[0065] In some other embodiments, as Figure 2 and Figure 3 shown, the third binding strap 6 can be a rope without elastic deformation. A channel for the rope to pass through is processed at the first side 11. The third binding strap 6 can be pulled at the first side 11 to make the first side 11 contract. When the body 1 is in the winding position, grasp both ends of the third binding strap 6 and pull to make the first side 11 generate wrinkles under the action of inertia and adapt to the neck size of the experimental animal, and then tie a knot at both ends of the third binding strap 6 to keep the first side 11 in this contracted size. It can be understood that in this state, both ends of the third binding strap 6 can be used as the fifth fixing member 71 and the sixth fixing member 72 in the third fixing assembly 7 respectively.

[0066] Please refer to Figures 2 to 5, in some embodiments, the number of the first binding straps 2 is two, and the two first binding straps 2 are oppositely arranged on the body 1; the number of the first fixing members 31 is two, and each first fixing member 31 is arranged at the outwards suspended end of a first binding strap 2 and on the side of the first binding strap 2 facing the body 1; the number of the second fixing members 32 is two, one second fixing member 32 is arranged at the first preset position of the body 1, and one second fixing member 32 is arranged at the outwards suspended end of one of the first binding straps 2 and on the side of the first binding strap 2 away from the body 1.

[0067] In this embodiment, the number of the first binding straps 2 is two, and the specific setting method is as Figure 2 shown. Since the first binding straps 2 will overlap at the first preset position after binding, the number of the second fixing members 32 in this embodiment is two. One of the second fixing members 32 is arranged at the end of the first binding strap 2 extending outwards. When in use, first fix the first binding strap 2 with the second fixing member 32 on the body 1, and then fix the first binding strap 2 without the second fixing member 32 on the current second fixing member 32 to complete the binding operation.

[0068] Please refer to Figure 1 and Figure 2 , in some embodiments, the body 1 has a relatively arranged third side 13 and a fourth side 14. The first side 11, the third side 13, the second side 12 and the fourth side 14 sequentially enclose the outer edge of the body 1. The fixator further includes a fourth fixing component 8. The fourth fixing component 8 includes a seventh fixing member 81 and an eighth fixing member 82. The seventh fixing member 81 is arranged on the third side 13, and the eighth fixing member 82 is arranged on the fourth side 14. The eighth fixing member 82 is detachably connected to the seventh fixing member 81.

[0069] In this embodiment, the fourth fixing component 8 is as Figure 1 shown. The seventh fixing member 81 and the eighth fixing member 82 are arranged in a long strip shape. This way can enable the body 1 to be directly fixed through the third side 13 and the fourth side 14 after being wound.

[0070] Optionally, multiple seventh fixing members 81 and multiple eighth fixing members 82 can be set to realize the fixing of the body 1 under the winding of experimental animals with different body types.

[0071] Please refer to Figure 1 and Figure 2, in some embodiments, the length of the second side 12 is greater than the length of the first side 11. In this way, the main body 1 has a trapezoidal structure with a smaller upper part and a larger lower part. The first side 11 is arranged close to the neck of the experimental animal, so the length of the first side 11 can be slightly greater than the neck circumference of the experimental animal. The second side 12 is close to the tail of the experimental animal. Considering the abdominal size of the experimental animal, the second side 12 can be slightly greater than the abdominal circumference size of the experimental animal to improve the adaptability between the main body 1 and the body shape of the experimental animal.

[0072] In some embodiments, the first fixing component 3 and / or the second fixing component 5 and / or the fourth fixing component 8 is / are Velcro.

[0073] In some embodiments, the second fixing member 32 and the fourth fixing member 52 are integrally formed with the main body 1, and the outer surface of the main body 1 has fluff. Optionally, the sixth fixing member 72 and the eighth fixing member 82 can also be integrally formed with the main body 1. In this way, the first fixing component 3, the second fixing component 5, the third fixing component 7, and the fourth fixing component 8 are all Velcro structures. The Velcro has a rough hook-like hair structure and a fluff structure. The second fixing member 32, the fourth fixing member 52, the sixth fixing member 72, and the eighth fixing member 82 are integrally formed with the main body 1, that is, the surface of the main body 1 is made into a fluff structure. Taking the first fixing component 3 as an example, when the first fixing member 31 is a rough hook-like hair structure, it can be directly attached to the outer surface of the main body 1 to complete the fixing of the first binding band 2. This way can include all areas of the main body 1 in the fixing area of the first binding band 2, making the attachment operation of the first binding band 2 more flexible. The fixing methods of the second binding band 4, the third binding band 6, and the third side 13 and the fourth side 14 of the main body 1 are the same as those of the first binding band 2.

[0074] In some embodiments, the main body 1 is a grid structure. The grid structure can maintain the fixed state of the experimental animal without completely covering the trunk part of the experimental animal. When the user also needs to perform other injection operations on the experimental animal, this design can make the whole operation more convenient, without disassembling and assembling the main body 1 to adjust the posture or binding area of the experimental animal, improving the operation efficiency.

[0075] In the above technical solution, the fixator includes a body 1, two groups of first binding straps 2, a first fixing component 3, four groups of second binding straps 4, and a second fixing component 5. The body 1 has a first side 11 and a second side 12, and the first side 11 and the second side 12 are arranged opposite to each other; the two groups of first binding straps 2 include at least one first binding strap 2. One end of the first binding strap 2 is connected to the body 1 and is arranged between the first side 11 and the second side 12. The other end of the first binding strap 2 is suspended outward, and the first binding strap 2 is an elastic band; the first fixing component 3 includes a first fixing member 31 and a second fixing member 32. The first fixing member 31 is arranged at the outwardly suspended end of the first binding strap 2, and the second fixing member 32 is arranged on the body 1 and is arranged at a first preset position. The first fixing member 31 and the second fixing member 32 are detachably connected; the four groups of second binding straps 4 include two second binding straps 4, and the two second binding straps 4 are arranged in parallel on the second side 12. The other ends of the four groups of second binding straps 4 are suspended outward; the second fixing component 5 includes a third fixing member 51 and a fourth fixing member 52. The number of the third fixing members 51 corresponds to the number of the second binding straps 4. The third fixing member 51 is arranged at the outwardly suspended end of the second binding strap 4, and the fourth fixing member 52 is arranged on the body 1 and is arranged at a second preset position. The third fixing member 51 and the fourth fixing member 52 are detachably connected; in this technical solution, the body 1 can be placed in a winding position. When the body 1 is placed in the winding position, the first side 11 of the body 1 is close to the neck of the experimental animal and winds around to wrap the torso of the experimental animal inside the body 1. The first binding strap 2 winds around the periphery of the body 1 and then fixes the experimental animal once through the first fixing member 31 and the second fixing member 32. The second binding strap 4 bends from the second side 12 towards the first side 11 and fixes the experimental animal twice through the third fixing member 51 and the fourth fixing member 52. The tail of the experimental animal protrudes from outside between the second side 12 and the two second binding straps 4. Since the head of the experimental animal protrudes from the first side 11, and the body 1 is made of a soft material, the first binding strap 2 is an elastic band and is wrapped outside the body 1, and the second binding strap 4 is also fixed outside the body 1. Therefore, the experimental animal will not be squeezed during the binding process. In this way, the experimental animal is in a calm state and the tail will not shake, and intravenous injection operations can be carried out. Moreover, since the head and neck of the experimental animal are outside the first side 11, blood measurement and the like can also be carried out on the experimental animal. Since the entire device is made of flexible materials, the user can quickly bind and fix the experimental animal without involving the screwing operation of hard parts such as screws, improving the use convenience and further improving the binding efficiency.

[0076] Finally, it should be noted that although the above embodiments have been described in the text and drawings of the specification of the present utility model, the patent protection scope of the present utility model cannot be limited thereby. Any technical solution resulting from equivalent structural or equivalent process substitution or modification made based on the substantial concept of the present utility model and using the content recorded in the text and drawings of the specification of the present utility model, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, etc., are all included within the patent protection scope of the present utility model.
