Abstract
Description
Technical Field
[0001] This utility model relates to the field of animal experimental technology, specifically a Barnes maze device with an electrically powered escape prevention structure. Background Technology
[0002] The Barnes maze is a classic experimental setup based on the behavioral characteristics of rodents. Its design fully utilizes the rodents' inherent photophobia, preference for dark environments, and exploratory instincts. During the experiment, animals are placed on a bright, open circular platform. Their behavioral reinforcement mechanism manifests as actively escaping the open area and entering a dark, narrow target box below the platform. Through repeated training, the animals develop spatial memory and accurately locate the target box. Because this model effectively avoids the physical interference of swimming experiments, it is particularly suitable for studying stress-related memory mechanisms and neurobehavioral phenotypic analysis in gene knockout mice, making it a key tool in neuroscience and genetics.
[0003] Currently, the Barnes maze faces two major technical bottlenecks: First, the maze platform surfaces are mostly made of smooth, non-irritating materials, which cannot provide sufficient aversive environmental stimuli for experimental animals, resulting in insufficient escape motivation. This not only significantly prolongs the time it takes for animals to locate the target box, but also affects the validity of spatial memory data due to the excessive randomness of exploration behavior; Second, the platform generally lacks physical protective structures around its perimeter, making it easy for experimental animals to fall directly from the platform edge and escape, thus increasing the rate of invalid experiments.
[0004] Based on this, a Barnes maze device with an electrified escape prevention structure is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

Detailed Implementation
[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0024] In one embodiment, such as Figures 1-5As shown, a Barnes maze device with an electrically conductive anti-escape structure includes an experimental platform 11 and a conductive sleeve 14. A conductive pad 12 is mounted on the upper end of the experimental platform 11, and a conductive coating is sprayed onto the upper end of the conductive pad 12. Several first connecting frames are fixedly mounted on the bottom end of the experimental platform 11, each fixed to one end of a support tube 13. The support tube 13 is mounted on the upper end of a base plate. Support frames 22 are symmetrically arranged on the upper end of the base plate. A first wire 16 is connected to one end of the conductive sleeve 14, and the other end of the first wire 16 is electrically connected to one end of a second wire 18. The second wire 18 is connected to the output end of an AC voltage regulating component 20. Electrically connected, the output end of the AC voltage regulating component 20 is also electrically connected to a third wire 19, the other end of the third wire 19 is equipped with a conductive clip 21, the conductive clip 21 is clamped and connected to the conductive pad 12, the AC voltage regulating component 20 is fixed on the second connecting frame, the second connecting frame is fixed inside a support frame 22, a traction mechanism for pulling the first wire 16 is provided between the two support frames 22, and an escape prevention mechanism for preventing animals from escaping is provided on the outside of the experimental platform 11. The traction mechanism facilitates the pulling and support of the first wire 16, and the escape prevention mechanism can prevent animals from detaching from the upper end of the conductive pad 12 during use;
[0025] The traction mechanism includes a guide frame 23, which is fixedly mounted between two support frames 22. The guide frame 23 has a guide groove inside, and a sliding seat 24 is slidably mounted within the guide groove. A rotating frame 25 is rotatably mounted at the bottom end of the sliding seat 24. A clamping plate 26 is slidably mounted on the inner side of the rotating frame 25, and the clamping plate 26 is rotatably mounted on one end of a screw 27. A threaded hole is provided at the bottom end of the rotating frame 25 corresponding to the position of the screw 27. In use, when an experiment is required, the conductive sleeve 14 is installed on the tail of the experimental mouse and secured with a rope or tape. Based on the desired length of the first wire 16, the first wire 16 is pulled, and then the screw 27 is rotated. Under the action of the thread, the conductive sleeve 14 is... The clamping plate 26 slides inside the rotating frame 25, fixing the first wire 16. Then, the AC voltage regulating component 20 is activated. Since the positive and negative terminals of the AC voltage regulating component 20 are electrically connected to the second wire 18 and the third wire 19 respectively, the third wire 19 is electrically connected to the upper conductive layer of the conductive pad 12 through the conductive clamp 21, and the second wire 18 is electrically connected to the experimental mouse through the conductive sleeve 14, so that the experimental mouse acts as a conductor. When the experimental mouse moves on the upper conductive layer of the conductive pad 12, it receives an electric shock, thereby stimulating the experimental mouse to perform the experiment. It is worth noting that the AC voltage regulating component 20 uses existing components, and the internal structure and working principle of the AC voltage regulating component 20 are common knowledge and will not be described in detail here.
[0026] The sliding seat 24 is provided with several balls on both sides and at the bottom. The inner side of the guide groove is provided with a limiting groove corresponding to the position of the balls. In use, it is convenient to reduce friction when the sliding seat 24 slides inside the guide frame 23, so that the sliding seat 24 can be displaced according to the movement of the experimental mouse.
[0027] The escape prevention mechanism includes an escape prevention cage 28. Several third connecting frames are fixedly mounted at the bottom of the escape prevention cage 28. The other end of each third connecting frame is fixedly connected to a sliding block 32. The sliding block 32 is slidably disposed inside the support tube 13. Fixed grooves are provided on the outer side of the support tube 13 at positions corresponding to the third connecting frames. A threaded hole is provided in the middle of the sliding block 32. The sliding block 32 is fitted onto a threaded rod 33. The threaded rod 33 is rotatably disposed inside the support tube 13. The threaded rod 33 is fixedly mounted at the output end of a motor 34. The motor 34 is fixedly mounted at the upper end of the support tube 13. The motor 34 is electrically connected to a control component 35, which is fixedly mounted on a second connecting frame. During use, in experiments, the user controls the motor 34 to start via the control component 35. The output end of the motor 34 drives the threaded rod 33 to rotate. Under the action of the thread, the sliding block 32 moves the escape prevention cage 28, thus protecting the upper end of the conductive pad 12.
[0028] The escape-proof cage 28 has several second conductive blocks 31 arranged in an array at its upper end. Each second conductive block 31 is electrically connected to a fourth wire 30 on one side, and each fourth wire 30 is electrically connected to a first conductive block 29 on the other side. The first conductive blocks 29 are all fixedly attached to the upper end of the conductive pad 12. In use, the conductive layer at the upper end of the conductive pad 12 connects the escape-proof cage 28 to the output terminal of the AC voltage regulating component 20 through the first conductive blocks 29, the fourth wire 30, and the second conductive blocks 31. When the experimental mouse is in close contact with the escape-proof cage 28, the experimental mouse is shocked, thereby preventing the experimental mouse from always being close to the escape-proof cage 28.
[0029] The conductive sleeve 14 is fixedly provided with a fixing frame 15. The fixing frame 15 has several mounting holes on its inner side. In use, a rope can be passed through the mounting holes on the inner side of the fixing frame 15 to fix the conductive sleeve 14 to the tail of the experimental mouse.
[0030] The conductive sleeve 14 is fixedly provided with a protective spring 17 at its end. The protective spring 17 is sleeved on the first wire 16. When in use, it prevents the experimental mouse from biting the first wire 16 and causing the first wire 16 to break.
[0031] The above embodiment discloses a Barnes maze device with an electrically conductive anti-escape structure. When an experiment is required, a conductive sleeve 14 is installed on the tail of a laboratory mouse and secured with ropes or tape. Based on the desired length of the first conductor 16, the first conductor 16 is pulled, and then the screw 27 is rotated. Under the action of the thread, the clamping plate 26 slides inside the rotating frame 25, thus securing the first conductor 16. Then, the AC voltage regulator 20 is activated. Since the positive and negative terminals of the AC voltage regulator 20 are electrically connected to the second conductor 18 and the third conductor 19 respectively, the third conductor 19 is connected via a conductive clamp. 21 is electrically connected to the upper conductive layer of the conductive pad 12, and the second wire 18 is electrically connected to the experimental mouse through the conductive sleeve 14, so that the experimental mouse acts as a conductor. When the experimental mouse moves on the upper conductive layer of the conductive pad 12, it is shocked and stimulated to conduct the experiment. At the same time, the user controls the motor 34 to start through the control component 35. The output end of the motor 34 drives the threaded rod 33 to rotate. Under the action of the thread, the sliding block 32 drives the anti-escape cage 28 to move, so that the anti-escape cage 28 protects the upper part of the conductive pad 12. At the same time, when the experimental mouse is in close contact with the anti-escape cage 28, the experimental mouse is shocked, thus preventing the experimental mouse from always being close to the anti-escape cage 28.
[0032] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
