Description

Technical Field

[0001] This utility model relates to the field of experimental equipment technology, specifically to a novel sleep deprivation device for rats and mice. Background Technology

[0002] The mouse and rat sleep deprivation device is an instrument that gently restricts sleep in animals without requiring training. Once the parameters are set, sleep deprivation experiments can be conducted on mice and rats without human intervention, making it suitable for sleep research, jet lag research, and intermittent sleep model simulation.

[0003] Existing sleep deprivation devices for mice and rats mostly use interfering rods that move left and right or rotate to force movement and thus disrupt sleep. However, regardless of how the height of the interfering rod is adjusted, the rat's tail will inevitably get caught. If a program is set to automatically stop rotating when the interfering rod is obstructed, the model is prone to failure, resulting in a waste of experimental animals, human and financial resources. If an automatic stop program is not set, the animals (especially those in the later stages of sleep deprivation with weaker reaction times) will be unable to escape after being caught by the interfering rod, which can cause severe compression of the tail and hind limbs, leading to ischemia, disability, or even death. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a novel sleep deprivation device for rats and mice, which can prevent the tail, hind limbs and other body parts of rats and mice from being pinched.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows.

[0006] A novel sleep deprivation device for rats and mice includes a base with a transparent cylinder on it. The transparent cylinder includes cylindrical walls that are open at both ends, and a partition is horizontally arranged at the bottom end of the cylindrical walls. A motor is installed inside the base, with the motor's rotation shaft vertically upward and passing through the transparent cylinder. On the top two sides of the motor's rotation shaft, there are interference rods arranged in a straight line and located at the bottom of the transparent cylinder, which rotate under the drive of the motor to disturb the sleep of rats and mice. Anti-pinch pads are placed on the interference rods to prevent them from pinching the rats and mice. The edges of the anti-pinch pads are detachably connected to the partition by bolts.

[0007] Preferably, the anti-pinch pad is a medical-grade silicone pad, and the edge of the anti-pinch pad is evenly provided with several rings of urination holes; the partition is evenly provided with several leakage outlets.

[0008] Preferably, the bottom end of the cylinder wall is provided with a plurality of support legs along the circumferential direction for supporting the cylinder wall.

[0009] Preferably, the base is provided with a top opening and a collection trough for collecting urine, and the bottom of the collection trough is a conical protrusion structure that is high in the center and gradually decreases towards the edge; the transparent cylinder is supported on the collection trough by support legs.

[0010] Preferably, the base, the collecting groove, the partition and the anti-pinch pad are each provided with a through hole in the center for the motor rotating shaft to pass through.

[0011] Preferably, the edge of the anti-pinch pad is evenly provided with a plurality of mounting lugs for bolts to pass through; the edge of the partition plate is provided with threaded holes for connection with bolts at positions corresponding to the mounting lugs.

[0012] Preferably, the outer wall of the cylinder is provided with a water bottle and a feeding trough; the outlet of the water bottle is connected to a water pipe that is inclined downward and inserted into the transparent cylinder, and the inner wall of the cylinder is provided with a water container located between the partition and the bottom end of the water pipe and having an open top for holding water; the outlet of the feeding trough is connected to a food feeding pipe that is inclined downward and inserted into the transparent cylinder, and the inner wall of the cylinder is provided with a food container located between the partition and the bottom end of the food feeding pipe and having an open top for holding food.

[0013] The technological advancements achieved by this utility model are as follows, due to the adoption of the above technical solutions.

[0014] This invention provides flexible protection for mice and rats by using an anti-pinch pad, completely avoiding the risk of direct injury or death from hard interference rods. The bolted connection structure ensures reliable fixation between the anti-pinch pad and the partition, effectively preventing displacement, accumulation, or wrinkling during rod rotation and ensuring the stability of the anti-pinch effect.

Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0018] A novel sleep deprivation device for rats and mice, combined with Figures 1 to 2 As shown, the device includes a base 1, on which a transparent cylinder 4 is mounted. A motor 2 is installed inside the base 1. The rotating shaft of the motor 2 is vertically upward and passes through the transparent cylinder 4. On the top two sides of the rotating shaft of the motor 2, there are interference rods 3 arranged in a straight line. The interference rods 3 are located at the bottom inside the transparent cylinder 4. The interference rods 3 rotate under the drive of the motor 2, thereby interfering with the sleep of mice and rats and achieving the purpose of sleep deprivation.

[0019] The transparent cylinder 4 includes a cylinder wall 41, which forms a cylinder with openings at both ends. A partition 43 is horizontally arranged at the bottom end of the cylinder wall 41. Several support legs 42 are arranged circumferentially at the bottom end of the cylinder wall 41 to support the cylinder wall 41, thereby supporting the entire transparent cylinder 4.

[0020] An anti-pinch pad 5 is mounted on the interference rod 3. The edge of the anti-pinch pad 5 is detachably connected to the partition plate 43 via bolts 44. The portion of the anti-pinch pad 5 that is in close contact with the interference rod 3 is lifted by the interference rod 3, while the remaining portion of the anti-pinch pad 5 is supported by the partition plate 43. When the interference rod 3 rotates, the anti-pinch pad 5 protects the mice and rats, preventing the interference rod 3 from pinching them, thus avoiding injury or death. Specifically, the anti-pinch pad 5 is a medical-grade silicone pad with several mounting tabs evenly distributed along its edge. These mounting tabs are used to pass through the bolts 44. Threaded holes are provided on the edge of the partition plate 43 at positions corresponding to the mounting tabs. These threaded holes are used to connect with the bolts 44, thereby enabling the installation, fixation, and detachment of the anti-pinch pad 5.

[0021] The edge of the anti-pinch pad 5 is evenly provided with several rings of urination holes 51; the partition 43 is evenly provided with several leakage outlets 431. The urination holes 51 and leakage outlets 431 are used to drain urine, thereby preventing urine accumulation and contamination of mice and rats; at the same time, the feces excreted by mice and rats will be drawn towards the edge of the anti-pinch pad 5 by the raised part of the anti-pinch pad 5 and the disturbance of the interference rod 3, thus facilitating manual cleaning of the feces. The base 1 is provided with a collection trough 10 with an open top, and the transparent cylinder 4 is supported on the collection trough 10 by the support legs 42. The collection trough 10 is used to collect urine, and the bottom of the collection trough 10 is a raised structure with a high center and gradually decreasing towards the edge, thereby preventing urine from remaining at the rotating shaft of the motor 2 and facilitating cleaning.

[0022] The base 1, the collection tank 10, the partition 43 and the anti-pinch pad 5 are respectively provided with through holes in their centers. The through holes are used to pass through the rotating shaft of the motor 2. At the same time, the rotating shaft of the motor 2 is rotated and sealed to the base 1, the collection tank 10 and the partition 43 respectively.

[0023] The outer wall of the cylinder 41 is provided with a water bottle 6 and a feeding trough 8. The water outlet of the water bottle 6 is connected to a water pipe 61, which is inserted into the transparent cylinder 4 at an angle downwards. The inner wall of the cylinder 41 is provided with a water container 7, which is located between the partition 43 and the bottom end of the water pipe 61 and has an open top. The water container 7 is used to hold water, so as to facilitate drinking for mice and rats. The feeding trough 8 is connected to a feeding tube 81, which is inserted into the transparent cylinder 4 at an angle downwards. The inner wall of the cylinder 41 is provided with a feeding trough 9, which is located between the partition 43 and the bottom end of the feeding tube 81 and has an open top. The feeding trough 9 is used to hold food, so as to facilitate feeding for mice and rats.

[0024] The working principle of this utility model is as follows: During the experiment, rats and mice were placed inside a transparent cylinder 4 and then on an anti-pinch pad 5. Motor 2 was activated, driving the interference rod 3 to rotate slowly and continuously, forcing the rats and mice to remain active and unable to fall asleep, thus achieving sleep deprivation. Simultaneously, the rats and mice's bodies were in direct contact with the anti-pinch pad 5, preventing direct collisions with the hard interference rod 3 and thus avoiding pinching injuries.

[0025] During the experiment: Urine treatment: Urine excreted by rats and mice drips down through the urination holes 51 at the edge of the anti-pinch pad 5, and then through the urine leakage outlets 431 on the partition 43, finally dripping into the collection tank 10 at the bottom, preventing excessive urine from accumulating in the experimental area and contaminating the rats and mice. The conical bottom of the collection tank 10 directs the urine to the edge, facilitating centralized collection and treatment.

[0026] Fecal disposal: The feces excreted by rats and mice fall onto the surface of the soft anti-pinch pad 5. As the anti-pinch pad 5 is fixed and the central area rises and moves slightly with the interference rod 3, the feces will gradually roll and gather towards the edge of the anti-pinch pad 5, making it easy for manual cleaning of the feces.

[0027] Feeding process: During the experiment, water and food can be added to the water tank 7 and food tank 9 through the external water bottle 6 and feeding trough 8 respectively to ensure the supply of food for the animals.
