Description

Technical Field

[0001] This invention belongs to the technical field of vertigo animal model construction device, and is particularly for the construction device for constructing multiple identical vertigo rat or mouse models simultaneously in small animals such as rats or mice. Specifically, it is a three-axis rotation multi-animal model construction device. Background Technology

[0002] Understanding the mechanism of vertigo is key to finding effective treatments and defining treatment requirements. To study the mechanism of vertigo and ensure the development of effective treatments or requirements, animal experiments are generally conducted by constructing animal models that exhibit vertigo sensations to obtain scientifically valid experimental data.

[0003] Currently, constructing animal models of dizziness requires obtaining consistent dizziness models from multiple batches, and only with a sufficient number of models can effective research results be obtained. In order to improve research efficiency, it is necessary to construct consistent dizziness animal models in batches.

[0004] The existing technology CN1911178A-Rat Motion-Induced Dizziness Rotation and Nystagmus Signal Acquisition and Processing System discloses a cradle-type biaxial rotation vertigo-providing structure. The biaxial approach cannot completely simulate the real vertigo construction process. In addition, the main purpose of the existing technology is to observe the anti-vertigo effect after the animal model is given medication. Therefore, it does not solve the problem of how to construct a uniform and sufficient vertigo animal model that is basically consistent with the real environment in batches.

[0005] Therefore, there is a need for a device for constructing vertigo animal models that can quickly, efficiently, and in large quantities produce consistent vertigo animal models. This invention provides a three-axis rotational multi-animal model construction device. Summary of the Invention

[0006] The existing technology CN118318750A - an air-floating vertigo animal model construction device - although it can simulate various complex vertigo construction states, because it is an air-floating solution, it is easily affected by the external environment during the model construction process, resulting in slightly weaker consistency of the constructed models, or requiring additional observation to select vertigo animal models with consistency. In addition, its internal space is limited, the number of model construction animals is also small, and the model construction animals are arranged in a linear array. When the sphere rotates, the position of the model construction animals relative to the rotation center is inconsistent. As a result, even if multiple model construction animal cavities are set inside, it is not possible to quickly and effectively construct vertigo animal models with consistency.

[0007] This invention utilizes a base with three nested rotating structures. The first rotating structure rotates along a plane perpendicular to the base. A second rotating structure rotates within the first, and a third rotating frame rotates within the second. The axes of rotation of the second and third rotating structures are always perpendicular to those of the first and third rotating frames. A model animal housing plate is positioned on the third rotating structure, its center aligned with the center of the third rotating structure. Model animal housing structures are also positioned on the third rotating structure, with each structure's position relative to the center and axis of the third rotating structure being consistent. This three-frame, three-axis approach ensures maximum rotational range for creating dizziness. Furthermore, because the housing structures are positioned consistently relative to the center and axis, multiple identical dizziness animal models can be created in a single batch.

[0008] The specific technical solution is as follows: a three-axis rotating multi-animal model construction device, which includes first to third rotating structures, first to third rotating motors, and a base.

[0009] The base is equipped with the first rotating motor.

[0010] The first rotating structure includes an outermost rotating frame that is driven to rotate by a first rotating motor, with the rotating shaft being the first rotating shaft; a second rotating motor is installed on the first rotating structure.

[0011] The second rotating structure includes a middle rotating frame that is driven to rotate by a second rotating motor. It rotates within the frame of the first rotating structure, with the rotating shaft being the second rotating shaft. A third rotating motor is installed on the second rotating structure.

[0012] The third rotating structure includes the innermost rotating structure, which is driven to rotate by the third rotating motor. It rotates within the frame of the second rotating structure, and the rotation axis is the third rotating axis. The third rotating structure is equipped with a model animal setting platform, and the setting platform is equipped with a housing structure for the model animal.

[0013] During the rotation, the second rotation axis is always perpendicular to the first rotation axis, and the second rotation axis is always perpendicular to the third rotation axis; the same position of the animal containment structure in each model is consistent with the relative position of the center of the third rotation structure and the third rotation axis, and the center of the third rotation structure is on the third rotation axis.

[0014] The above setup, through the coordinated rotation of three rotating structures and three corresponding rotating motors, can simulate various special motion states of vertigo model construction. The idea of ​​setting up three rotating motors allows for individual control over whether the motor rotates, and the rotation speed of each motor makes the construction of the rotating model more controllable. When constructing vertigo models for different batches, it is only necessary to ensure the consistency of the program settings. Since the rotation is controlled by the motors and is less affected by the environment, the consistency of the constructed models can be guaranteed. Furthermore, for vertigo models within the same batch, the relative positions of the central axis of the animal housing structure with respect to the center of the third rotating structure and the third rotation axis are consistent. This ensures that multiple models within the same batch have consistent animal models and will not exhibit model deviations due to different positions.

[0015] Furthermore, the third rotating structure is a hollow mounting platform, which includes a third rotating frame and a mounting plate with the same shape and size on the outer side of the third rotating frame. The frame wall of the first rotating structure is thicker than that of the second rotating structure, and the frame wall of the second rotating structure is thicker than that of the third rotating frame. This design minimizes the overall mass of the device while maintaining the strength of each frame. Additionally, the frame and mounting plate design ensures proper motor mounting and reduces the platform's weight due to its hollow structure.

[0016] Furthermore, the first to third rotating frames are set as rectangular or circular rotating frames. When a rectangular rotating frame is used, a square rotating frame is rotated to ensure the smallest possible rotating frame size for the same dimensions.

[0017] Furthermore, the setup plate has a setup surface with four receiving structures. These receiving structures are arranged along the diagonal direction of the setup surface, with two structures along each diagonal. The positions of the receiving structures corresponding to the animal's head in the model are oriented away from the center of the setup surface. This arrangement ensures that all four receiving structures are placed on the setup plate with minimal setup plate size.

[0018] Furthermore, the containment structure includes a containment tube for containing the model animal and a combination part that combines with the setting plate. The bottom of the combination part is a combination surface that effectively fits with the setting plate. Four sets of combination holes are provided on the setting plate along the diagonal direction. An extension rod that combines with the combination holes extends from the combination surface of the combination part. A fixing structure is also provided to simultaneously fix the four containment structures, which is used to stably fix the containment structures on the setting plate.

[0019] Furthermore, the fixing structure includes a fixing plate and a capped locking screw. The fixing plate has a threaded hole one at its center, and the setting plate has a threaded hole two at its center. After the receiving structure is set up, the fixing plate is positioned in front of the receiving structure, and the locking screw is rotated into threaded holes one and two. This rotation ensures the fixing plate makes tight contact with the receiving structure, locking it onto the setting plate. Because of the combination of the insert rod and the combination holes, along with the fixing plate, threaded holes one and two, and the capped locking screw, when the setting plate of the third rotating frame is facing the operator, the operating structure can be inserted into the combination hole simply by placing it perpendicular to the setting plate. Then, the fixing plate is placed in front of the receiving structure in the same direction, and finally, rotation locks all four receiving structures onto the setting plate without any positional change during rotation.

[0020] Furthermore, a setting plate is set on the third rotating frame, and the four accommodating structures are set within the construction space of the third rotating frame and the setting plate. This arrangement ensures that the overall thickness of the constructed third rotating frame and accommodating structures is small, reducing the size requirements for the second rotating structure, and consequently reducing the size requirements for the first rotating structure. Alternatively, a setting plate is set on each side of the third rotating frame, with four accommodating structures on each plate. The two setting plates are mirrored with a plane of symmetry parallel to the plane of the third rotating frame as the mirror plane, and the third rotation axis is also on the aforementioned plane of symmetry. This arrangement ensures that the relative positions of each accommodating slot with respect to the center of the third rotating structure and the third rotation axis are consistent, thus ensuring that eight consistent and effective model animals can be constructed at once, minimizing the time required to obtain a sufficient number of dizzy model animals.

[0021] Technical effect

[0022] By coordinating the three-layer rotating structure with the corresponding three rotating motors and ensuring the relative position of the central axis of each animal housing structure relative to the center of the third rotating structure and the third axis of rotation, it is possible to mass-produce consistent dizziness animal models. Furthermore, because the rotation is controlled by three rotating motors, the rotation mode can be set through the program, ensuring that the construction method of each batch of dizziness animal models is uniform and unaffected by external interference. Ultimately, this achieves the effect of quickly obtaining consistent dizziness animal models by using the same construction program multiple times.

[0023] Setting the receiving structure along the diagonal direction of the setting surface can minimize the area of ​​the setting plate and thus reduce the overall size of the device while ensuring the consistency of the positions of multiple receiving structures.

[0024] By setting a combination surface on the receiving structure and setting an extension rod on the combination surface, and setting a corresponding combination hole on the setting plate, the receiving structure can be set up through a quick plug-in operation. By setting a fixing structure to fix four receiving structures at the same time, the receiving structure can be quickly and effectively fixed.

[0025] By using a fixed plate and a capped locking screw, and by setting a threaded hole one in the center of the fixed plate and a threaded hole two in the center of the fixed plate, the entire housing structure can be set up by simply setting it in the direction perpendicular to the fixed plate. Finally, by rotating the capped locking screw, the setting and fixing of all housing structures can be completed quickly. The whole operation is simple and convenient.

[0026] By setting two setting plates on the third rotating frame, and using mirrored setting plates, it is possible to construct eight dizzy animal models in one go, which greatly shortens the time required to construct a sufficient number of model animals. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0046] refer to Figure 1-5 A three-axis rotating multi-animal model construction device, wherein the rat or mouse involved in the device is a rat or mouse; the three-axis rotating multi-animal model construction device provides a centrifugal force of 4 times gravity to ensure the construction of a vertigo model. It includes first to third rotating structures 41, first to third rotating motors 42, and a base 1. The front side of the first rotating structure 21 to the third rotating structure 41 is square.

[0047] The base 1 is equipped with a first rotary motor 22. The weight of the base 1 can withstand the rotational force above, and it can be equipped with a solid metal structure or a hollow liquid-filled structure to achieve counterweight.

[0048] The first rotating structure 21 includes an outermost first rotating frame, which is a square frame; it is driven to rotate by a first rotating motor 22, and the rotation axis is a first rotating shaft; a second rotating motor 32 is installed on the first rotating structure 21; in order to minimize the overall mass while ensuring the strength of the first rotating structure 21, the rotating frame is fixed on a U-shaped frame 24 combined with the first rotating motor 22. A conductive slip ring 23 is installed inside the U-shaped frame 24 to solve the problem of preventing the wires of the second rotating motor 32 from getting tangled. The conductive slip ring 23 rotates with the first rotating motor 22, separating the wires of the second motor from the rotational action of the first motor. The first rotating motor 22 is combined with the bottom frame of the corresponding rotating frame of the first rotating structure 21 to drive the first rotating structure 21 to rotate. The second rotating motor 32 is located in the middle of one of the left or right frames of the corresponding rotating frame of the first rotating structure 21.

[0049] The second rotating structure 31 includes a second rotating frame in the middle layer, which is driven to rotate by a second rotating motor 32. It rotates within the frame of the first rotating structure 21, with the rotation axis being a second rotating shaft. A third rotating motor 42 is mounted on the second rotating structure 31. The second rotating shaft is parallel to the corresponding edge of the bottom frame of the first rotating frame. A conductive slip ring 23, rotating with the second rotating motor 32, is also mounted on the side frame opposite to the second rotating motor 32 to prevent the wires of the third rotating motor 42 from tangling. This conductive slip ring 23 also extends and is fixed to a mounting plate on the corresponding side frame of the second rotating structure 31, and the mounting plate is assembled to the second rotating structure 31 by screws. The second rotating motor 32 also extends from the side frame of the first rotating structure 21 to the mounting plate, and the mounting plate is also assembled to the second rotating structure 31 by screws.

[0050] The third rotating structure 41 includes an innermost rotating structure, which is driven to rotate by a third rotating motor 42. It rotates within the frame of the second rotating structure 31, with the rotation axis being the third axis. The third rotating structure 41 has a rat or mouse placement platform, with the center of the third rotating structure 41 aligned. Four rat or mouse housing structures are set on the placement platform. The third rotating motor 42 is located on the bottom frame of the second rotating structure 31, and a rotating connection structure connecting the second rotating structure 31 and the third rotating structure 41 is set on the upper frame.

[0051] During the rotation, the second rotation axis is always perpendicular to the first rotation axis, and the second rotation axis is always perpendicular to the third rotation axis. The same position of each rat or mouse containment structure is consistent with the relative position of the center of the third rotation structure 41 and the third rotation axis. The center of the third rotation structure 41 is on the third rotation axis. That is, the distance from the same position of different containment structures to the center of the third rotation structure 41 is the same, and the distance from the same position of different containment structures to the third rotation axis is the same.

[0052] The third rotating structure 41 is a hollow mounting platform, which includes a third rotating frame and a mounting plate 43 with the same shape on the outer side of the third rotating frame. The frame wall of the first rotating structure 21 is thicker than the frame wall of the second rotating structure 31, and the frame wall of the second rotating structure 31 is thicker than the frame wall of the third rotating frame. This design can minimize the weight of the entire device while maintaining the strength of each frame. In addition, the mounting platform, with its frame and mounting plate 43, can accommodate the motor and reduce the weight of the mounting platform due to its hollow design. Setting the rotating frame as a hollow wiring rotating frame ensures that the wiring is concealed.

[0053] The maximum power of the first rotary motor 22 is greater than that of the second rotary motor 32. The maximum power of the second rotary motor 32 is greater than that of the third rotary motor 42. Since each motor has a different mass to bear, by gradually reducing the power of each motor, the smaller motors can be rotated in sequence, thereby reducing the weight of the equipment and avoiding the difficulty of setting up due to the excessive size of the equipment.

[0054] In this embodiment, the first to third rotating frames are set as square frames. When rotating a rectangular frame, rotating a square frame ensures the smallest possible rotating frame size for the same dimensions. However, it should not be ruled out that the first to third rotating frames may be set as rectangular or circular frames for other considerations.

[0055] refer to Figure 6-9 and Figure 12 The setting plate 43 is a square plate with one setting surface. Four receiving structures are set on the setting surface, with two structures arranged along each diagonal. The positions of the receiving structures corresponding to the rat or mouse head are oriented away from the center of the setting surface. This arrangement ensures that all four receiving structures are placed on the setting plate 43 with the smallest possible size.

[0056] refer to Figure 7 , Figure 9 and Figure 11 The specific housing structure includes a housing tube portion 51 for accommodating rats or mice and a mounting portion 52 that assembles with a setting plate 43. The bottom of the mounting portion 52 is a mounting surface 521 that effectively fits against the setting plate 43. Four sets of mounting holes 431 are provided on the setting plate 43 along a diagonal direction. Extension rods 522 extend from the mounting surface 521 of the mounting portion 52 and assemble with the mounting holes 431. A fixing structure is provided to stably fix the housing structure to the setting plate 43. Two extension rods 522 extend from each mounting surface 521, corresponding to two extension rods in each set of mounting holes 431. The extension rods 522 and the mounting holes 431 are interference-fitted. An elastic layer is provided on the outer side of the extension rods 522. This ensures that the assembled housing structure is stable within the mounting holes, allowing for simple insertion of the housing structure during installation.

[0057] refer to Figure 11The container portion 51 is implemented as follows: The container portion 51 includes an outer cylinder portion 511 with one end closed and the other open. The outer cylinder portion 511 has a longitudinal through-hole 5111 extending to the closed section. An adjustment portion 512, which enters from the open end and adjusts its position according to the size of the rat or mouse, is provided inside the outer cylinder portion 511. The adjustment portion 512 includes an inner cylinder portion 5121 and an adjustment locking structure. The inner cylinder portion 5121 also has one end closed and the other open, with the open end of the inner cylinder portion 5121 opposite to the closed end of the outer cylinder portion 511. The adjustment locking structure includes a threaded rod 5122 extending from the through-hole 5111 and connected to the inner cylinder portion 5121. A locking nut 5123 is provided on the outside of the threaded rod 5122. When adjusted to a suitable position, the position of the adjustment portion 512 is locked by rotating the locking nut 5123. This forms an adjustable container for holding rats or mice. More specifically, the closed end of the outer cylinder portion 511 corresponds to the tail of a rat or mouse, and the adjustment portion 512 accommodates the head of a rat or mouse. When the accommodating structure is provided, the open end of the accommodating cylinder portion 51 is located in a direction away from the center of the setting surface.

[0058] refer to Figure 7 , Figure 9 and Figure 10 The specific implementation of the fixing structure is as follows: The fixing structure includes a fixing plate 61 and a capped locking screw 62; the fixing plate 61 has a threaded hole 63 at its center, and the setting plate 43 has a threaded hole 432 at its center. After the receiving structure is set, the fixing plate 61 is placed in front of the receiving structure, and the locking screw is rotated into the threaded hole 63 and the threaded hole 43. By rotating, the fixing plate 61 is brought into close contact with the receiving structure, locking the receiving structure onto the setting plate 43. Because of the combination of the extension rod and the combination hole 431, plus the cooperation of the fixing plate 61, the threaded hole 63, the threaded hole 432, and the capped locking screw 62, when the setting plate 43 of the third rotating frame is facing the operator, the operating structure can be inserted into the combination hole 431 by simply placing it perpendicular to the setting plate 43. Then, the fixing plate 61 is placed in front of the receiving structure in this direction, and finally, the four receiving structures can be locked onto the setting plate 43 by rotation, without any positional change during the rotation process. The capped locking screw 62 has a rotating handle 621 on its cap, which facilitates the rotation of the capped locking screw 62.

[0059] refer to Figure 6 and Figure 8To ensure better fixation of the fixing plate 61, it is also a square plate. After this setting, each side of the fixing plate 61 is perpendicular to the diagonals of the two setting plates 43, and the diagonals of the fixing plate 61 are less than or equal to the side lengths of the setting plates 43. This arrangement ensures that the edges of the fixing plate 61 effectively press against the receiving structure, guaranteeing the stability of the fixation after installation.

[0060] refer to Figure 6 , Figure 8 and Figure 10 The fixing plate 61 is provided with four rectangular notches 64 for adjusting the extension of the locking structure. The width of the four rectangular notches 64 is equal to the maximum width of the locking nut 5123. The four rectangular notches 64 extend to the area corresponding to the locking position that allows small mice to lock. This design not only ensures the fixing effect of the fixing plate 61, but also avoids affecting the strength of the fixing plate 61 due to the setting of the rectangular notches 64.

[0061] refer to Figure 9 and Figure 10 Four sets of protruding plates 65 are provided below the fixed plate 61. Each set of protruding plates 65 includes two parallel plates. Each set of parallel plates is perpendicular to the fixed plate 61. When in use, the two parallel plates of each set are outside the outer cylinder part 511 of the receiving structure, and the distance between the two parallel plates is equal to the outer diameter of the outer cylinder part 511. This arrangement can further avoid construction errors caused by shaking during rotation.

[0062] One or two setting plates 43 can be installed on the third rotating frame as needed, see reference. Figure 1 and Figure 6-7 The implementation method when setting a setting plate 43 is as follows: a setting plate 43 is set on the third rotating frame, and the accommodating structure part is set in the construction space of the third rotating frame and the setting plate 43. This setting can ensure that the thickness of the overall constructed third rotating frame and accommodating structure is small, which can reduce the size requirements of the second rotating structure 31, and thus reduce the size requirements of the first rotating structure 21.

[0063] Or, refer to Figure 3-5 and Figure 8-9 The implementation method of setting two setting plates 43 is as follows: one setting plate 43 is set on each side of the third rotating frame, and four receiving structures are set on each setting plate 43. The two setting plates 43 are mirrored with the plane of symmetry parallel to the plane where the third rotating frame is located as the mirror plane. The third rotating axis is also on the aforementioned plane of symmetry. This setting can ensure that the relative positions of each receiving slot with respect to the center of the third rotating structure 41 and the third rotating axis are consistent. This can ensure that eight consistent and effective model animals can be constructed at one time, thus minimizing the time required to obtain a sufficient number of dizzy model animals.

[0064] The above description is merely a specific embodiment of this application. Under the teachings of this application, those skilled in the art can make other improvements or modifications based on the above embodiments. Those skilled in the art should understand that the above specific description is only to better explain the purpose of this application, and the scope of protection of this application should be determined by the scope of the claims.
