Description

Technical Field

[0001] This invention relates to the field of rat gait technology, and in particular to an automatic rat posture control device for rat gait research. Background Technology

[0002] Rat gait research is an important research field with wide applications in neuroscience, pharmacology, genetics, and physiology. It assesses and understands gait patterns, motor function, coordination, balance, and nervous system function by collecting and analyzing biomechanical data of rats during walking.

[0003] For example, Chinese patent CN220344403U discloses a rat gait footprint collection device, including a base with uprights fixed on both sides. An elastic PET board is adhered to the inner side of the uprights, and an elastic baffle assembly is provided on the PET board. The bottom of the base has a groove filled with absorbent sponge, and water-writing paper is placed on top of the sponge. The baffle assembly includes a fixed plate and an arc-shaped plate. The fixed plate is fixed to the PET board, and the arc-shaped plate is elastically connected to the fixed plate by a spring. This device uses a unidirectional baffle assembly, so the rat can only walk in one direction during the walking process, and the footprints will not be confused due to backward movement. The water content of the sponge is relatively uniform, so that a relatively uniform and accurate footprint watermark can be left no matter where the rat walks. The water-writing paper used to collect gait footprint watermarks in this device can be reused after heating because the watermarks disappear, saving paper and benefiting the environment.

[0004] However, during the above-mentioned use, the movement trajectory of the experimental mice is uncertain, and the mice may turn back during the movement. In addition, the mice themselves have a certain climbing ability, and the movement trajectory of the mice is irregular. A straight line alone cannot well explain the gait of the mice, thus making the experiment somewhat simplistic and affecting the subsequent overall data analysis.

[0005] Therefore, this application provides an automatic rat posture control device for rat gait research to meet the needs. Summary of the Invention

[0006] The technical problem to be solved by this invention is to provide an automatic rat posture control device for rat gait research, which solves the problems of uncertain movement trajectory of experimental rats, the possibility of rats walking backwards during movement, the fact that experimental rats have a certain climbing ability, and the irregular movement trajectory of experimental rats. A straight line alone cannot well explain the gait of experimental rats, thus making the experiment somewhat singular and affecting the subsequent overall data analysis.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0008] An automatic control device for rat posture research in rat gait includes an experimental box with a ramp fixedly connected to its inner cavity and an observation window on its outer surface; and an auxiliary automatic component for changing the movement trajectory of the experimental rat, the auxiliary automatic component being connected to the ramp.

[0009] Optionally, the auxiliary automatic component includes a bent plate fixedly connected to the top of the observation window, a weakening part is provided in the middle of the bent plate, a support bracket is attached to the bottom of the weakening part, and a support plate is attached to the end of the bent plate.

[0010] Optionally, a curved ramp is fixedly connected to the top of the ramp, and a weakening section 2 is provided in the middle of the curved ramp.

[0011] Optionally, both ends of the bent plate are bent upwards, the inner cavity of the bent plate is hollow, and the weakening part is opened in the middle of the bent plate, and there are two of them.

[0012] Optionally, the bottom of the support bracket is fixedly connected to the inner cavity of the experimental chamber, and the top of the support bracket is attached to the bottom of the bent plate.

[0013] Optionally, the surface of the support plate is provided with a plurality of slots, the bottom of the support plate is fixedly connected to the inner cavity of the experimental chamber, and the top of the support plate is attached to the end of the bent plate.

[0014] Optionally, one end of the curved plank is fixedly connected to the top of the slope, and the other end is an open end that bends upward. The weakening part two is located in the middle of the curved plank.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects:

[0016] In the above scheme, the auxiliary automatic component can ensure that after the experimental mouse enters, it can choose whether to move in a straight line according to the experimental requirements. When the experimental mouse moves, if the experimental mouse moves to the corresponding position, it indicates that the next movement will be a straight line or an irregular movement, which improves the overall flexibility of the device. At the same time, the experimental mouse will not leave the experimental site no matter how it moves, which can effectively observe the overall activity state of the experimental mouse, improve the analysis effect of subsequent data, and make the experimental results more diverse.

[0017] By setting up a bending board, the experimental mouse is wrapped by both sides of the bending board, forming a straight line. This allows for testing of the mouse's straight line data, improving the stability and validity of the data, and thus ensuring the authenticity and diversity of subsequent data.

[0027] The automatic rat posture control device for rat gait research provided by the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0028] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0029] Generally, terms can be understood at least partly from their use in context. For example, depending at least partly on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in a singular sense, or a combination of features, structures, or characteristics in a plural sense. Additionally, the term "based on" can be understood not necessarily to convey an exclusive set of factors, but rather, alternatively, depending at least partly on the context, to allow for the presence of other factors that are not necessarily explicitly described.

[0030] It is understood that the meanings of “on”, “above”, and “above” in this utility model should be interpreted in the broadest manner, such that “on” not only means “directly on” something, but also includes the meaning of being “on” something with an intervening feature or layer, and that “above” or “above” not only means “on” something, but also includes the meaning of being “on” something without an intervening feature or layer.

[0031] Furthermore, spatially related terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for convenience to describe the relationship of one element or feature to one or more other elements or features, as illustrated in the accompanying drawings. Spatially related terms are intended to cover different orientations in the use or operation of the device other than those depicted in the accompanying drawings. The device may be oriented in other ways, and the spatially related descriptive terms used herein can be interpreted similarly.

[0032] like Figures 1 to 5As shown, an embodiment of the present invention provides an automatic rat posture control device for rat gait research, including an experimental box 1, an inclined ramp 2 fixedly connected to the inner cavity of the experimental box 1, and an observation window 3 on the outer surface of the experimental box 1; and an auxiliary automatic component, which is used to change the movement trajectory of the experimental rat. The auxiliary automatic component is connected to the inclined ramp 2. Through the auxiliary automatic component, it can be ensured that after the experimental rat enters, it can choose whether to move in a straight line according to the experimental requirements. When the experimental rat moves, if the experimental rat moves to the corresponding position, it indicates that the next movement will be a straight line or an irregular movement, which improves the overall flexibility of the device. At the same time, no matter how the experimental rat moves, it will not leave the experimental site, which can effectively observe the overall activity state of the experimental rat, improve the analysis effect of subsequent data, and make the experimental results more diverse.

[0033] like Figures 2 to 5 As shown, the auxiliary automatic component includes a bent plate 4 fixedly connected to the top of the observation window 3. A weakening section 5 is provided in the middle of the bent plate 4. A support bracket 6 is attached to the bottom of the weakening section 5. A support plate 7 is attached to the end of the bent plate 4. A curved ramp 8 is fixedly connected to the top of the ramp 2. A second weakening section 9 is provided in the middle of the curved ramp 8. The two ends of the bent plate 4 are made of plastic, while the middle part is made of flexible material. The inner cavity of the middle part of the bent plate 4 is hollowed out. The first weakening section 5 is located on the bent plate 4. Two support brackets are located in the middle. The support bracket 6 is made of plastic and its bottom is fixedly connected to the inner cavity of the experimental box 1. The top of the support bracket 6 is attached to the bottom of the weakening part 5. The middle of the support bracket 6 is hollow. The surface of the support plate 7 has slots. The bottom of the support plate 7 is fixedly connected to the inner cavity of the experimental box 1. The top of the support plate 7 is attached to the end of the bending plate 4. The bending springboard 8 is made of flexible material. One end is fixedly connected to the top of the ramp 2, and the other end is open. The weakening part 9 is located in the middle of the bending springboard 8.

[0034] In the above structure, after the experimental mouse is released from the top of the ramp 2, it is driven into the interior of the bending plate 4. After entering, if the experimental mouse does not move from the weakened part 5, the two sides of the bending plate 4 will not bend towards the middle due to gravity. At this time, the experimental mouse moves irregularly, which is used to record irregular data. During the continued crawling of the experimental mouse, if the experimental mouse steps on the weakened part 5, the weakened part 5 will collapse downwards due to the flexible material. At this time, the two ends of the bending plate 4 will bend towards the middle due to the gravity in the middle. During the downward movement of the weakened part 5, it will be supported by the support 6. At the same time, the bending board 8 will prevent the experimental mouse from turning back after entering the interior of the bending plate 4. This effect prevents the experimental mouse from returning to the initial position during crawling, which would reduce the validity of the data. After the above steps are completed, the experimental mouse is wrapped by the two sides of the bending plate 4, forming a straight line. This allows for testing of the experimental mouse's straight line data, improving the stability and validity of the data, thereby ensuring the authenticity and diversity of subsequent data.

[0035] Finally, the mouse crawls to the edge of the inner cavity of experimental chamber 1, and can be removed through the gate.

[0036] The working principle of the technical solution provided by this utility model is as follows:

[0037] After releasing the experimental mouse from the top of ramp 2, it is guided into the interior of the bending plate 4. Once inside, if the mouse does not move from the weakened section 5, the sides of the bending plate 4 will not bend inwards due to gravity. At this point, the mouse's movement is irregular, and this is for recording irregular data. As the mouse continues to crawl, if it steps on the weakened section 5, this section will collapse downwards due to the flexible material. At this point, both ends of the bending plate 4 will bend inwards due to gravity in the middle. During the downward movement of the mouse, it will be supported by the support 6. At the same time, the curved board 8 will prevent the mouse from turning back after it enters the curved board 4. This effect prevents the mouse from returning to the initial position during crawling, thus reducing the validity of the data. After the above steps are completed, the mouse is wrapped by both sides of the curved board 4, forming a straight line. This allows for testing of the mouse's straight line data, improving the stability and validity of the data, thereby ensuring the authenticity and diversity of subsequent data. Finally, the mouse crawls to the edge of the inner cavity of the experimental box 1 and can be taken out through the gate.

[0038] This invention encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this invention. To provide the public with a thorough understanding of this invention, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand the invention even without these details. Furthermore, to avoid unnecessary misunderstanding of the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0039] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
