[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present application in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope protected by the present application.

[0035] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present application are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0036] It should also be noted that when an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element through an intermediate element.

[0037] In addition, the descriptions involving "first", "second", etc. in the present application are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions conflicts or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present application.

[0038] Existing fixation devices generally include a circular top and an enclosing part. At least one ventilation hole is provided on the circular top. The enclosing part extends along the circumference of the circular top towards one side to form an open cylindrical shape. When fixing the head of a rat, the opening of the enclosing part is sleeved on the head of the rat. It can be seen that such an existing fixation device can only fix the head of the rat and has no effect on fixing the torso of the rat. When fixing the rat, the body of the rat may move randomly, which is not convenient for the operator to perform corresponding operations on the rat. At the same time, the rat is also likely to scratch the operator.

[0039] For this reason, the embodiments of the present application provide a rat fixation device that can fix the head and torso of the rat. The rat is not likely to move randomly, which can prevent the rat from biting or scratching the operator during the experiment, so as to facilitate the operator to perform corresponding operations.

[0040] The following will describe in detail some embodiments of the present application with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0041] As Figure 1 shown, the rat fixation device provided by the embodiments of the present application includes a neck clamping member 10, a back clamping member 20, and a connecting rod 30.

[0042] Among them, the neck clamping member 10 includes a control member 101 and a grasping member 102. The control member 101 is connected to the grasping member 102. The control member 101 is used to control the grasping member 102 to open or close so as to grasp the neck of a rat. The back clamping member 20 is used to fix the back of the rat. The connecting rod 30 is connected to the neck clamping member 10 and the back clamping member 20.

[0043] It should be noted that the neck clamping member 10 can fix the neck of the rat through the grasping member 102. In addition, when it is necessary to grasp the rat, the grasping member 102 can be controlled by the control member 101 to grasp the rat. For example, when the rat is placed in a cage, the grasping member 102 can be opened through the control member 101, the grasping member 102 is placed on the neck of the rat, and then the grasping member 102 is closed to grasp the rat and fix the neck of the rat. In this way, the time for grasping and immobilizing can be saved.

[0044] It should be noted that the back clamping member 20 can fix the entire back of the rat. For example, it can be surrounded around the circumference of the back of the rat to fix the back of the rat. Of course, the back clamping member 20 can also only fix a part of the back of the rat. For example, it can fix the fur on the back of the rat. As long as the back clamping member 20 can keep the torso of the rat stable, there is no limitation.

[0045] It should be noted that after the rat fixing device of the present application immobilizes the rat, the operator can perform corresponding operations according to needs. For example, perform intravenous blood collection on the rat. When the operator performs the corresponding operation, the rat can be placed downward for the corresponding operation, or the connecting rod 30 can be held by hand and the rat can be turned over to perform the corresponding operation on the rat. There is no limitation.

[0046] In the rat fixing device of the embodiment of the present application, when the operator needs to immobilize the rat, the grasping member 102 can be controlled by the control member 101 to open so as to grasp the rat and fix the neck of the rat. Then, the back of the rat is fixed by the back clamping member 20, and further the rat is immobilized. Both the head and the torso of the rat can be immobilized, and the rat is not likely to move around, which can prevent the operator from being bitten or scratched during the experiment, so as to facilitate the operator to perform corresponding operations. And, during the process of fixing the rat by this rat fixing device, there is no need to use anesthesia and other immobilization measures, which reduces the operation difficulty and improves the convenience and speed of the experiment.

[0047] Such as Figure 1As shown, in the embodiment of the present application, the neck clamping member 10 includes a first clamping member 11 and a second clamping member 12. The first clamping member 11 includes a first hand-held portion 111 and a first jaw 112 connected to each other. The second clamping member 12 includes a second hand-held portion 121 and a second jaw 122 connected to each other. The first clamping member 11 and the second clamping member 12 are rotatably connected. The first hand-held portion 111 and the second hand-held portion 121 can drive the first jaw 112 and the second jaw 122 to approach or separate from each other by approaching or separating from each other. The first hand-held portion 111 and the second hand-held portion 121 are configured to form a control member 101, and the first jaw 112 and the second jaw 122 are configured to form a grasping member 102. When an operator needs to fix a rat, the operator can hold the first hand-held portion 111 and the second hand-held portion 121, so that the first hand-held portion 111 and the second hand-held portion 121 approach or separate from each other. With the relative rotation of the first clamping member 11 and the second clamping member 12, the first jaw 112 and the second jaw 122 can be driven to approach or separate from each other, so as to realize the opening or closing of the grasping member 102. For example, when the first jaw 112 and the second jaw 122 are separated from each other, the grasping member 102 can be opened to facilitate placing the grasping member 102 on the neck of the rat. Then, the first jaw 112 and the second jaw 122 are driven to approach each other, and the grasping member 102 is closed to grasp the rat and simultaneously fix the neck of the rat. In this embodiment, by using the first hand-held portion 111 and the second hand-held portion 121 to control the first jaw 112 and the second jaw 122, it is convenient for the operator to control the grasping member 102, and the operation is simple and safe, and it is not easy to cause the rat to be injured or die. At the same time, when grasping and fixing the rat, since the first hand-held portion 111 and the second hand-held portion 121 are far away from the grasping member 102, it is not easy for the rat to bite the operator either.

[0048] In other embodiments, the control member 101 can control the opening or closing of the grasping member 102 by electric control. For example, the control member 101 can control the operation of the motor connected to the grasping member 102 through a set button, and then drive the grasping member 102 to open or close. Among them, the grasping member 102 can refer to the structure of the grasping member 102 in the above manual control mode. In this embodiment, the neck clamping member 10 adopts an electric control method, which can be convenient to operate and avoid the death of the rat caused by improper manual operation.

[0049] As Figure 1As shown, in the embodiment of the present application, the first holding part 111 and the first jaw 112 are on the same side, and the second holding part 121 and the second jaw 122 are on the same side. When it is necessary to separate the first jaw 112 and the second jaw 122, that is, when it is necessary to open the grasping member 102 to grasp the rat, the operator needs to press and hold the first holding part 111 and the second holding part 121, so that the first holding part 111 and the second holding part 121 approach each other, and further the first jaw 112 and the second jaw 122 move away. Further, in this embodiment, when there is no external force, the first jaw 112 and the second jaw 122 are close to each other, that is, the grasping member 102 is in a closed state, which means that only when it is necessary to grasp the rat, the operator needs to press and hold the first holding part 111 and the second holding part 121. After grasping, the first holding part 111 and the second holding part 121 can be released, so that the grasping member 102 stably fixes the neck of the rat, thus facilitating the operation of the operator.

[0050] Of course, in other embodiments, the first clamping member 11 and the second clamping member 12 may also be cross - arranged, that is, the first holding part 111 and the second jaw 122 are on the same side, and the second holding part 121 and the first jaw 112 are on the same side. When it is necessary to separate the first jaw 112 and the second jaw 122, that is, when it is necessary to open the grasping member 102 to grasp the rat, the operator needs to spread apart the first holding part 111 and the second holding part 121, so that the first jaw 112 and the second jaw 122 move away. When it is necessary to fix the neck of the rat, the first holding part 111 and the second holding part 121 need to be pressed and held to keep the first jaw 112 and the second jaw 122 close. Further, in this embodiment, when there is no external force, the first jaw 112 and the second jaw 122 are away from each other, that is, the grasping member 102 is in an open state, which means that only when it is necessary to fix the neck of the rat, the operator needs to press and hold the first holding part 111 and the second holding part 121.

[0051] As Figure 1 shown, in the embodiment of the present application, the first jaw 112 and the second jaw 122 enclose a clamping hole 10a, and the clamping hole 10a is used for clamping the neck of the rat. By clamping the neck of the rat through the clamping hole 10a, the neck of the rat can be clamped stably and safely, and it can be avoided that the first jaw 112 and the second jaw 122 are too close to clamp the rat, or even cause the death of the rat. Of course, in other embodiments, the neck of the rat can also be clamped only by the contact between the first jaw 112, the second jaw 122 and the neck of the rat, which will not be elaborated here.

[0052] Exemplarily, the first jaw 112 is arranged to extend in an arc shape, and the second jaw 122 is arranged to extend in an arc shape. When the gripper 102 is closed, the ends of the first jaw 112 and the second jaw 122 abut against each other, and the first jaw 112 and the second jaw 122 enclose a clamping hole 10a in a circular shape to stably fix the neck of the rat.

[0053] As Figure 1 shown, in the embodiment of the present application, a first elastic pad (not shown in the figure) is provided on the inner wall of the first jaw 112 facing the second jaw 122, and a second elastic pad (not shown in the figure) is provided on the inner wall of the second jaw 122 facing the first jaw 112. When the gripper 102 grabs and holds the neck of the rat, the provided first elastic pad and second elastic pad can play a role in increasing friction and adapting to the neck of the rat to ensure a firm grip on the neck of the rat. At the same time, the first elastic pad and the second elastic pad can also provide a certain degree of protection to the rat, preventing the harder parts of the first jaw 112 and the second jaw 122 from directly contacting the rat to reduce harm to the rat.

[0054] Exemplarily, the first elastic pad and the second elastic pad are integrally provided and extend from the end of the first jaw 112 around the hole wall of the clamping hole 10a to the end of the second jaw 122.

[0055] Exemplarily, both the first elastic pad and the second elastic pad are rubber pads to ensure harmless contact with the rat.

[0056] As Figure 1 shown, in the embodiment of the present application, the neck clamping member 10 further includes a first rotating shaft (not shown in the figure). The first clamping member 11 is provided with a first rotating portion 113, and the second clamping member 12 is provided with a second rotating portion 123. The first rotating shaft passes through the first rotating portion 113 and the second rotating portion 123. The first clamping member 11 and the second clamping member 12 can rotate around the first rotating shaft to realize the rotational connection between the first clamping member 11 and the second clamping member 12. When assembling the neck clamping member 10, it is only necessary to connect the first clamping member 11 and the second clamping member 12 to the first rotating shaft respectively, and the assembly is convenient and fast. Of course, in other embodiments, the first clamping member 11 and the second clamping member 12 can also be directly rotationally connected. For example, the first rotating portion 113 and the second rotating portion 123 are hinged.

[0057] Exemplarily, the first rotating portion 113 includes two first rotating pieces arranged at intervals, and the first rotating shaft passes through the two first rotating pieces so that the first clamping member 11 can stably rotate around the first rotating shaft. The second rotating portion 123 includes two second rotating pieces arranged at intervals, and the first rotating shaft passes through the two second rotating pieces so that the second clamping member 12 can stably rotate around the first rotating shaft.

[0058] As Figure 1As shown, in the embodiment of the present application, a part of the structure of the connecting rod 30 forms a first rotating shaft. Taking a part of the connecting rod 30 as the first rotating shaft can save additional structural connections and costs. At the same time, when the neck clamping member 10 grabs and fixes, the connecting rod 30 remains stable and does not affect other structures. Of course, in other embodiments, the first rotating shaft and the connecting rod 30 are different structures. For example, the connecting rod 30 can be directly connected to the neck clamping member 10, for example, connecting to the first rotating part 113 or the second rotating part 123.

[0059] As Figure 1 As shown, in the embodiment of the present application, the neck clamping member 10 further includes a first torsion spring 13. The first torsion spring 13 is sleeved on the first rotating shaft, and one torsion bar of the first torsion spring 13 is connected to the first clamping member 11, and the other torsion bar is connected to the second clamping member 12, so that without external force, the first jaw 112 and the second jaw 122 are close to each other. In this way, after the gripper 102 clamps the neck of the rat, the operator can remove the hand from the first hand-held part 111 and the second hand-held part 121, so as to keep the first jaw 112 and the second jaw 122 fixed to the neck of the rat, facilitating other operations of the operator. For example, in the structure where the foregoing first hand-held part 111 and the first jaw 112 are on the same side, and the second hand-held part 121 and the second jaw 122 are on the same side, the operator only needs to press and hold the first hand-held part 111 and the second hand-held part 121 only when it is necessary to grab the rat. After grabbing, the first hand-held part 111 and the second hand-held part 121 can be released so that the gripper 102 stably fixes the neck of the rat, thus facilitating the operation of the operator.

[0060] Exemplarily, the first torsion spring 13 is located between the two foregoing first rotating pieces and between the two foregoing second rotating pieces to keep the first torsion spring 13 stable.

[0061] As Figure 1As shown, in the embodiment of the present application, the back clamping member 20 includes a third clamping member 21 and a fourth clamping member 22. The third clamping member 21 includes a third hand-held portion 211 and a third clamping jaw 212 which are connected to each other. The fourth clamping member 22 includes a fourth hand-held portion 221 and a fourth clamping jaw 222 which are connected to each other. The third clamping member 21 and the fourth clamping member 22 are rotatably connected. The third hand-held portion 211 and the fourth hand-held portion 221 can drive the third clamping jaw 212 and the fourth clamping jaw 222 to approach or separate from each other by approaching or separating from each other. After the operator fixes the neck of the rat through the neck clamping member 10, the operator can hold the third hand-held portion 211 and the fourth hand-held portion 221, so that the third hand-held portion 211 and the fourth hand-held portion 221 approach or separate from each other. As the third clamping member 21 and the fourth clamping member 22 rotate relative to each other, the third clamping jaw 212 and the fourth clamping jaw 222 can be driven to approach or separate from each other, so as to fix the back of the rat by the third clamping member 21 and the fourth clamping member 22. For example, when the third clamping jaw 212 and the fourth clamping jaw 222 separate from each other, they can be placed on the back of the rat. Then, the third clamping jaw 212 and the fourth clamping jaw 222 are driven to approach each other to clamp the fur on the back of the rat, thereby fixing the back of the rat to realize the fixation of the torso of the rat. In this embodiment, the third clamping jaw 212 and the fourth clamping jaw 222 are controlled by the third hand-held portion 211 and the fourth hand-held portion 221, which is convenient for the operator to operate. At the same time, when fixing the torso of the rat, since the third hand-held portion 211 and the fourth hand-held portion 221 are far away from the clamping position, it is not easy for the rat to scratch the operator.

[0062] Of course, in other embodiments, the back clamping member 20 may also be provided with an adhesive tape, which is adhered to the back of the rat to fix the back of the rat.

[0063] As Figure 1 shown, in the embodiment of the present application, the third hand-held portion 211 and the third clamping jaw 212 are on the same side, and the fourth hand-held portion 221 and the fourth clamping jaw 222 are on the same side. When it is necessary to separate the third clamping jaw 212 and the fourth clamping jaw 222, the operator needs to press and hold the third hand-held portion 211 and the fourth hand-held portion 221, so that the third hand-held portion 211 and the fourth hand-held portion 221 approach each other, and then the third clamping jaw 212 and the fourth clamping jaw 222 separate. Further, in this embodiment, when there is no external force, the third clamping jaw 212 and the fourth clamping jaw 222 are close to each other, that is, in a clamping state, so as to maintain a stable clamping state of the back clamping member 20 and facilitate the operation of the operator.

[0064] Exemplarily, the third clamping member 21 and the fourth clamping member 22 are clamping pieces. When the third clamping jaw 212 and the fourth clamping jaw 222 approach each other, one end of the two clamping pieces abuts, and the other end is away from each other. In this way, the fur on the back of the rat can be clamped by the abutment of the ends of the two clamping pieces, realizing stable fixation of the back of the rat.

[0065] As Figure 1 shown, in the embodiment of the present application, the inner wall of the third clamping jaw 212 facing the fourth clamping jaw 222 is provided with a third elastic pad (not shown in the figure), and the inner wall of the fourth clamping jaw 222 facing the third clamping jaw 212 is provided with a fourth elastic pad 2221. The provided third elastic pad and the fourth elastic pad 2221 can play a role in increasing friction to ensure firm clamping of the back of the rat. At the same time, the third elastic pad and the fourth elastic pad 2221 can also provide certain protection to the rat, preventing the harder parts of the third clamping jaw 212 and the fourth clamping jaw 222 from directly contacting the rat to reduce harm to the rat.

[0066] Exemplarily, both the third elastic pad and the fourth elastic pad 2221 are rubber pads to ensure harmless contact with the rat.

[0067] As Figure 1 shown, in the embodiment of the present application, the back clamping member 20 further includes a second rotating shaft (not shown in the figure). The third clamping member 21 is provided with a third rotating portion 213, and the fourth clamping member 22 is provided with a fourth rotating portion 223. The second rotating shaft passes through the third rotating portion 213 and the fourth rotating portion 223. The third clamping member 21 and the fourth clamping member 22 can rotate around the second rotating shaft to realize the rotational connection of the third clamping member 21 and the fourth clamping member 22. When assembling the back clamping member 20, only the third clamping member 21 and the fourth clamping member 22 need to be respectively connected to the second rotating shaft, and the assembly is convenient and fast. Of course, in other embodiments, the third clamping member 21 and the fourth clamping member 22 can also be directly rotationally connected. For example, the third rotating portion 213 and the fourth rotating portion 223 are hingedly connected.

[0068] Exemplarily, the third rotating portion 213 includes two third rotating pieces arranged at intervals, and the second rotating shaft passes through the two third rotating pieces so that the third clamping member 21 can stably rotate around the second rotating shaft. The fourth rotating portion 223 includes two fourth rotating pieces arranged at intervals, and the second rotating shaft passes through the two fourth rotating pieces so that the fourth clamping member 22 can stably rotate around the second rotating shaft.

[0069] As Figure 1As shown, in the embodiment of the present application, a part of the structure of the connecting rod 30 forms a second rotating shaft. Taking a part of the connecting rod 30 as the second rotating shaft can save additional structural connections and costs. At the same time, when the back clamping member 20 fixes the back of the rat, the connecting rod 30 remains stable and does not affect other structures. Of course, in other embodiments, the second rotating shaft and the connecting rod 30 are different structures. For example, the connecting rod 30 can be directly connected to the back clamping member 20, for example, connected to the third rotating part 213 or the fourth rotating part 223.

[0070] As Figure 1 As shown, in the embodiment of the present application, the back clamping member 20 further includes a second torsion spring 23. The second torsion spring 23 is sleeved on the second rotating shaft, and one torsion bar of the second torsion spring 23 is connected to the third clamping member 21, and the other torsion bar is connected to the fourth clamping member 22, so that in the absence of external force, the third clamping claw 212 and the fourth clamping claw 222 approach each other. In this way, after the back clamping member 20 clamps the back of the rat, the operator can remove the hand from the third hand-held part 211 and the fourth hand-held part 221, so as to keep the third clamping claw 212 and the fourth clamping claw 222 fixed to the back of the rat, facilitating other operations by the operator.

[0071] Exemplarily, the second torsion spring 23 is located between the two aforementioned third rotating pieces and between the two aforementioned fourth rotating pieces to maintain the stability of the second torsion spring 23.

[0072] As Figure 1 As shown, in the embodiment of the present application, the connecting rod 30 is a telescopic connecting rod 30. The connecting rod 30 can be telescoped along the direction from the neck clamping member 10 to the back clamping member 20 as needed. In this way, the distance between the neck clamping member 10 and the back clamping member 20 can be adjusted, so that the rat fixing device can adapt to rats of different body sizes and hold rats of different body sizes, thereby facilitating the operator to perform corresponding operations on the rats.

[0073] Exemplarily, the connecting rod 30 at least includes two rod bodies sleeved with each other, one of which can extend into the other rod body or extend out of the other rod body. One rod body is connected to the neck clamping member 10, and the other rod body is connected to the back clamping member 20. In this way, by contracting or extending the two rod bodies, the distance between the neck clamping member 10 and the back clamping member 20 can be adjusted, so as to adapt to rats of different body sizes.

[0074] As Figure 1As shown, in the embodiment of the present application, the rat fixing device further includes a hanging rod 40, and the hanging rod 40 is arranged between the neck clamping member 10 and the back clamping member 20. The operator can pick up the hanging rod 40, and thus pick up the rat fixing device. After the rat fixing device fixes the rat, the rat can be lifted by the hanging rod 40 to facilitate the operator to perform corresponding operations. Since the hanging rod 40 is located between the neck clamping member 10 and the back clamping member 20, when picking up the hanging rod 40, the balance of the rat fixing device can be maintained to facilitate the operator to perform corresponding operations.

[0075] In the embodiment of the present application, the hanging rod 40 is rotatably connected to the connecting rod 30. When the operator picks up the hanging rod 40 to lift the rat, the rat can be kept facing down to avoid the rat biting or scratching the operator.

[0076] Exemplarily, the hanging rod 40 is provided with a rotating hole, and the connecting rod 30 passes through the rotating hole to realize the rotational connection between the hanging rod 40 and the connecting rod 30.

[0077] As Figure 1 shown, in the embodiment of the present application, the rat fixing device further includes a head cover 50. The head cover 50 is connected to the neck clamping member 10 or the connecting rod 30 and is located on the side of the neck clamping member 10 away from the back clamping member 20. The head cover 50 is provided with a positioning hole 50a, and the positioning hole 50a is arranged opposite to the grasping member 102. After the neck clamping member 10 fixes the rat's neck and the back clamping member 20 fixes the rat's back, the rat's head can be placed in the head cover 50 to further fix the rat's head and avoid the rat biting the operator.

[0078] Exemplarily, the positioning hole 50a is opposite to the aforementioned clamping hole 10a, and in the direction away from the neck clamping member 10, the aperture of the positioning hole 50a increases. That is to say, the head cover 50 extends in the direction away from the neck clamping member 10 and is arranged in a flared shape. In this way, the head cover 50 can cover the rat's head and improve the safety of the operator's operation.

[0079] The above are only the preferred embodiments of the present application, and do not limit the patent scope of the present application. Any equivalent structural transformation made under the application concept of the present application by using the content of the specification and drawings of the present application, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present application.
