[0002] In the field of biomedical engineering, sleep research is an important branch that involves measuring sleep patterns, neural electrical activity, and physiological indicators in animal models such as mice or rats. This research helps us understand the impact of sleep on brain function and physical health, as well as the mechanisms of sleep disorders such as insomnia, sleep apnea syndrome, epilepsy, and depression.

[0003] For example, patent CN219019915U provides a sleep deprivation device for laboratory mice, including a base, an experimental chamber, and a gearbox; the experimental chamber is disposed on the upper surface of the base; the base is a hollow shell, and a first geared motor with its output shaft facing upward is disposed inside the base; the housing of the first geared motor is fixedly connected to the base, and the output shaft of the first geared motor is connected to a connecting shaft via a coupling. The connecting shaft passes upward through the top wall of the base and the bottom wall of the experimental chamber in sequence, and then extends into the interior of the experimental chamber. The upper end of the connecting shaft is fixedly connected to the gearbox. At the bottom of the gearbox, multiple horizontal disturbance rods are radially and evenly distributed inside. Each disturbance rod passes through the side wall of the gearbox, and one end of the disturbance rod inside the gearbox is connected to a driven bevel gear. The gearbox also contains a second geared motor with a horizontal output shaft. The housing of the second geared motor is fixedly connected to the gearbox body. A driving bevel gear is connected to the output shaft of the second geared motor. The driving bevel gear meshes with each driven bevel gear simultaneously, which enables the disturbance rods to not only revolve around the central axis but also rotate on their own axis, completely preventing the experimental mice from sleeping inside the experimental chamber.

[0004] However, the above technical solutions have the following problems: using only a single method to achieve sleep deprivation does not result in ideal sleep deprivation effects. Utility Model Content

[0030] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0031] like Figure 1-2 As shown, an embodiment of this utility model provides a sleep deprivation experimental device, which includes: a support base 1, a drive assembly 2, a housing 3, and a rotating rod 4. The drive assembly 2 is fixed on the support base 1, and the rotating rod 4 is disposed inside the housing 3. The housing 3 and the rotating rod 4 are connected to the movable end of the drive assembly 2. The drive assembly 2 can drive the housing 3 and the rotating rod 4 to rotate independently and synchronously relative to the support base 1.

[0032] In this invention, the movable end of the drive assembly 2 is connected to the housing 3 and the rotating rod 4, and has three states: 1. driving the rotating rod 4 to rotate alone; 2. driving the housing 3 to rotate alone; 3. driving the rotating rod 4 and the housing 3 to rotate simultaneously. In use, different driving methods can be selected according to specific circumstances. In addition, when driving the rotating rod 4 and the housing 3 to rotate simultaneously, the animal in the housing 3 is subjected to sleep deprivation through striking and centrifugal rotation, thereby improving the effect of sleep deprivation.

[0033] Specifically, the support base 1 includes a support frame 11, the top of which forms a mounting groove for fixing the drive component 2, and the drive component 2 is fixed in the mounting groove.

[0034] Furthermore, the top of the support frame 11 is movably abutted against the box 3. The purpose of this design is that the box 3 is often relatively large in size because it needs to hold experimental animals. When the drive assembly 2 drives the box 3 to rotate, the box 3 may sway relative to the support frame 11. The support frame 11 provides movable support for the box 3, so that the box 3 can rotate stably relative to the support frame 11.

[0035] Furthermore, a number of steel balls 12 are embedded in the top of the support frame 11. The steel balls 12 abut against the box body 3. The steel balls 12 provide support for the box body 3 on the one hand, and assist the box body 3 in rotating on the other hand.

[0036] Specifically, the drive assembly 2 includes a first drive member 21 and a second drive member 22. The first drive member 21 is fixed to the top of the support frame 11 and connected to the housing 3, and is used to drive the housing 3 to rotate relative to the support base 1. The second drive member 22 is fixed to the top of the support frame 11 and fixed to the rotating rod 4, and is used to drive the rotating rod 4 to rotate relative to the support base 1.

[0037] Furthermore, the first driving component 21 includes a first driving motor 211 and a first gear 212. The first driving motor 211 is fixed to the top of the support frame 11, and the first gear 212 is fixed to the output end of the first driving motor 211. The first gear 212 meshes with the housing 3, thereby driving the housing 3 to rotate relative to the support frame 11.

[0038] Furthermore, the second driving component 22 includes a second driving motor 221 and a driving rod 222. The second driving motor 221 is fixed to the top of the support frame 11. One end of the driving rod 222 is fixed to the output end of the second driving motor 221, and the other end of the driving rod 222 extends into the housing 3 and is fixed to the rotating rod 4. The output end of the second driving motor 221 rotates, thereby driving the rotating rod 4 to rotate through the driving rod 222.

[0039] Furthermore, the housing 3 includes a main body 31 and a toothed ring 32. The toothed ring 32 is fixed to the bottom of the main body 31 and meshes with the first driving member 21. The first driving member 21 drives the main body 31 to rotate by driving the toothed ring 32 to rotate.

[0040] Furthermore, the main body 31 includes a chassis 311, a side wall cylinder 312, and a top cover 313. The toothed ring 32 is fixed to the bottom of the chassis 311, the side wall cylinder 312 is detachably fixed to the chassis 311, and the top cover 313 is placed on the side wall cylinder 312. The chassis 311, the side wall cylinder 312, and the top cover 313 together form an animal holding space.

[0041] Furthermore, the chassis 311 has a groove 311a that matches the side wall cylinder 312. The bottom of the side wall cylinder 312 is engaged in the groove 311a to achieve a detachable connection between the side wall cylinder 312 and the chassis 311. The purpose of this design is to facilitate the cleaning of the animal holding space. When cleaning is required, the side wall cylinder 312 can be separated from the chassis 311 to collect and clean the residue on the chassis 311.

[0042] Furthermore, the sidewall tube 312 is made of transparent material, which makes it easier for the experimenter to observe the state of the animal inside.

[0043] Furthermore, the sleep deprivation experimental device of this utility model also includes a ring display module 5, which is fixed on the chassis 311 and arranged around the side wall cylinder 312. The inner ring surface of the ring display module 5 is used to display pictures or images for the animals in the animal holding space to view, thereby further depriving them of sleep.

[0044] The beneficial effects of this utility model are:

The drive assembly is fixed on the support base, and the rotating rod is disposed inside the housing. The housing and the rotating rod are connected to the movable end of the drive assembly. The drive assembly can drive the housing and / or the rotating rod to rotate relative to the support base. The movable end of the drive assembly is connected to the housing and the rotating rod, and has three states: 1. Driving the rotating rod to rotate alone; 2. Driving the housing to rotate alone; 3. Driving both the rotating rod and the housing to rotate simultaneously. In use, different driving methods can be selected according to specific circumstances. In addition, when driving the rotating rod and the housing to rotate simultaneously, the animal inside the housing is subjected to sleep deprivation through impact and centrifugal force, thereby improving the sleep deprivation effect.
