Description

Technical Field

[0001] This utility model relates to the field of animal experimental device technology, and in particular to an animal sleep deprivation device. Background Technology

[0002] Sleep deprivation in animal experiments is an important method for studying sleep function. By depriving animals of sleep time, changes in their physiological, behavioral, and cognitive functions can be observed, thereby revealing the key role of sleep in maintaining life activities.

[0003] Currently, there are several types of commonly used physical sleep deprivation devices: platform water bath method, gentle stimulation method, and rotator deprivation method. However, these existing technologies all have significant drawbacks. The platform water bath method keeps animals in a water environment for a long time, causing strong stress responses in experimental animals and seriously interfering with the objectivity of experimental results. The gentle stimulation method is highly dependent on manual operation and has problems such as low efficiency and difficulty in standardizing stimulation intensity and frequency. The rotator deprivation method carries the risk of animal limbs being accidentally pinched or caught in the rotating parts. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an animal sleep deprivation device that can effectively deprive animals of sleep, avoid external stress, reduce artificial dependence, and minimize the risk of physical injury to animals.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: an animal sleep deprivation device, including a box and a cage, wherein the cage is fixed to the upper end of the box, characterized in that a sleep disturbance device and a driving device are installed inside the box, the sleep disturbance device includes a moving component, and bristles are fixed on the moving component. When the moving component moves, the bristles sweep across the inside of the cage and disturb the animal inside the cage. The driving device is used to drive the moving component to move.

[0006] Furthermore, the moving component includes a first mounting shaft, a second mounting shaft, and a belt. The two ends of the belt are respectively engaged with the first mounting shaft and the second mounting shaft via pulleys. The first mounting shaft and the second mounting shaft are rotatably mounted inside the housing. A first gear is fixed on the first mounting shaft. The driving device drives the first gear to rotate. The bristles are fixed on the outer surface of the belt.

[0007] Furthermore, the bristles are made of silicone or nylon.

[0008] Furthermore, the driving device includes a drive motor and a second gear, the second gear being fixed on the output shaft of the drive motor, and the second gear driving the first gear to rotate via a synchronous belt.

[0009] Furthermore, the cage is provided with a partition that divides the cage into multiple independent small cages. Each small cage has a lid hinged to its upper end. The lid has a limiting groove. Each small cage has a limiting protrusion integrally provided on its upper edge at the non-hinged part. The limiting groove and the limiting protrusion correspond to each other, so that the lid will not be lower than the upper edge of the small cage when closed.

[0010] Furthermore, the partition is a railing with intervals.

[0011] Furthermore, a switch, a speed adjustment knob, and a frequency adjustment knob are fixed on the outer surface of the housing. The switch, speed adjustment knob, and frequency adjustment knob are electrically connected to the drive motor. The switch is used to turn the drive motor on or off, the speed adjustment knob is used to change the rotation speed of the drive motor, and the frequency adjustment knob is used to change the operating frequency of the drive motor.

[0012] Furthermore, a drawer is slidably connected inside the box, and the drawer is located directly below the sleep disturbance device. The drawer is used to collect trash on the sleep disturbance device.

[0013] Compared with existing technologies, the advantages of this invention are that it uses movable flexible bristles for physical stimulation, which eliminates the physiological stress on animals caused by water and avoids the risk of animal limbs being pinched in the rotarod deprivation method, thus improving physical safety, animal welfare and experimental reliability; in addition, the sleep disturbance device is driven by a motor to achieve automated operation, reducing the reliance on manual operation and ensuring the standardization of stimulation intensity and frequency and the repeatability of the experiment.

[0015] Figure 2 This is an exploded view of the present invention. Detailed Implementation

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0017] like Figure 1-2As shown, an animal sleep deprivation device includes a housing 1 and a cage 2. The cage 2 is fixed to the upper end of the housing 1. A sleep disturbance device and a driving device are installed inside the housing 1. The driving device includes a drive motor 41 and a second gear 42. The second gear 42 is fixed on the output shaft of the drive motor 41. The second gear 42 drives the sleep disturbance device to operate via a synchronous belt 43. The sleep disturbance device includes a moving component, which includes a first mounting shaft 31, a second mounting shaft 32, and a belt 33. The two ends of the belt 33 are respectively connected to the first mounting shaft 31, the second mounting shaft 32, and the belt 33 via pulleys (not shown in the figure). A first mounting shaft 31 and a second mounting shaft 32 mesh with each other, and both are rotatably mounted inside the housing 1. A first gear 34 is fixed on the first mounting shaft 31, and the second gear 42 drives the first gear 34 to rotate via a synchronous belt 43. The drive device drives the sleep disturbance device to operate automatically, reducing reliance on manual operation and ensuring the standardization of stimulation intensity and frequency and the repeatability of the experiment. Brush bristles 35 are fixed to the outer surface of the belt 33. The bristles 35 are made of soft materials such as silicone or nylon. The bristles 35 will not cause physical harm to the experimental animals, such as pinching injuries. As the bristles 35 move with the belt 33, they sweep across the inside of the cage 2, disturbing the animals inside and achieving sleep deprivation. A drawer 5 is slidably connected inside the housing 1, located directly below the sleep disturbance device. The drawer 5 collects debris such as animal feces and shed hair from the bristles 35 and belt 33, making cleaning the entire device easier. A partition 21 divides the cage 2 into multiple independent small cages 22. Each small cage 22 has a lid 23 hinged to its upper end. The lid 23 has a limiting groove 231. The upper edge of the small cage 22 at the non-hinged part has an integral limiting protrusion 221. The limiting groove 231 corresponds to the limiting protrusion 221, so that the lid 23 will not be lower than the upper edge of the small cage 22 when closed. The partition 21 is a series of bars that are spaced apart. In a single experiment, it can accommodate multiple animals while ensuring that the individuals are in an independent and partially contactable natural state. This can meet the requirements for controlling variables during the experiment without affecting the normal socialization and movement of the experimental animals.

[0018] A switch 11, a speed adjustment knob 12, and a frequency adjustment knob 13 are fixed on the outer surface of the housing 1. The switch 11, the speed adjustment knob 12, and the frequency adjustment knob 13 are electrically connected to the drive motor 41. The switch 11 is used to turn the drive motor 41 on or off, the speed adjustment knob 12 is used to change the rotation speed of the drive motor 41, and the frequency adjustment knob 13 is used to change the operating frequency of the drive motor 41.

[0019] In this embodiment, the control of the drive motor 41 is achieved using existing control circuits.
