Description

Built-in animal sleep deprivation device

Technical Field

The invention belongs to the field of animal experimental instruments, and particularly relates to a built-in animal sleep deprivation device.

Background

The insomnia is a big problem which troubles modern people, the chronic insomnia is troubled by 6 to 10 percent in comparison with adults according to epidemiological research, and the sleep time is shortened, so that the occurrence of metabolic diseases such as obesity, diabetes and the like is promoted. The use of sleep deprivation animal models is essential in the study of insomnia. The device for establishing the sleep deprivation animal model reported at present mainly comprises 4 types of devices, namely a rotating wheel or a rotating drum type driving device, a horizontal platform type device, a runway type device and a deprivation rod type device. Wherein the mode of depriving the rod-type can be better reaches sleep and deprives, and is less to experimental animals' damage itself simultaneously. However, the existing devices are generally driven by a motor from the outside to extend into a deprivation box, or a deprivation rod in a cage needs a special equipment support. Extending into the cage from the outside requires bottom notching, causing bedding leakage and failure to place bedding causing discomfort to the animal. Need use special cage utensil then will change the animal feeding environment, the cost obviously improves, has simultaneously can't place the bedding and padding or change the difficulty, and the cage utensil is cleared up inconveniently, and the device is heavy, a great deal of defects such as area is big.

Disclosure of Invention

In view of the above problems, the present invention provides a built-in animal sleep deprivation device, which aims to solve the technical problems of high cost, heavy weight, difficult cleaning, large floor space and the like of the existing animal sleep deprivation device.

The invention adopts the following technical scheme:

device is deprived in built-in animal sleep includes the slip bench, slip bench below is equipped with the slider of trompil, be equipped with the lead screw between the slip bench both ends and pass the slider, the slider below is fixed with the connecting rod, the connecting rod bottom end is fixed with the sleep and deprives the pole, the motor is installed to slip bench left end, slip bench top is equipped with the fixed plate that is used for fixed cage utensil and slip bench.

Further, the outer end of the motor is connected with a wire, and the tail end of the wire is connected with an aviation connector.

Further, the connecting rod comprises an upper frame and a lower frame, and the upper frame and the lower frame are connected in a sliding mode and fixed through bolts.

Furthermore, a screw hole is formed in the upper end of the lower frame, a penetrating guide groove is formed in the upper frame along the length direction, and the bolt penetrates through the screw hole and the guide groove and then is locked and fixed.

Furthermore, the sleep deprivation rod is H-shaped, the middle part of the sleep deprivation rod is provided with an open slot, and a protruding part formed by bending the tail end of the lower frame inwards is embedded into the open slot and is fixed with the H-shaped sleep deprivation rod.

Furthermore, a sliding groove is formed in the bottom surface of the sliding table frame, a convex block is arranged at the upper end of the sliding block, and the convex block is embedded into the sliding groove.

Furthermore, a round hole is formed in the top of the sliding table frame, a through hole is formed in the fixed plate, and a screw is screwed into the through hole and the corresponding round hole, so that the sliding table frame is fixed with the cage.

The invention has the beneficial effects that: the invention provides a built-in animal sleep deprivation device which can be directly built in an original large mouse cage without special cages or bottom grooving and other transformation on the original cage, so that padding leakage caused by grooving is avoided, experimental animals are directly raised in original experimental conditions, and animal stress reaction caused by environmental change is reduced to the maximum extent; the device is connected with the cage cover part and can be taken down along with the cover at the same time, so that the cage is convenient to clean; sleep deprivation is carried out by adopting a sleep deprivation rod, and the deprivation process is mild by regulating the speed and controlling the reciprocating time, so that the damage to experimental animals is reduced; the height of the sleep deprivation rod is adjusted through the liftable connecting rod, and the defect that padding cannot be placed in a traditional sleep deprivation device is overcome.

Drawings

FIG. 1 is a block diagram of a built-in animal sleep deprivation device according to an embodiment of the present invention.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

In order to explain the technical means of the present invention, the following description will be given by way of specific examples.

Fig. 1 shows the structure of a built-in animal sleep deprivation device provided in the embodiment of the present invention, and only the parts related to the embodiment of the present invention are shown for convenience of explanation.

As shown in fig. 1, the device is deprived in built-in animal sleep that this embodiment provided includes smooth rack 1, smooth rack 1 below is equipped with the slider 2 of trompil, be equipped with the lead screw 3 between smooth rack 1 both ends and

pass slider

2, 2 belows of slider are fixed with the connecting rod, the connecting rod bottom is fixed with sleep and deprives pole 6, motor 7 is installed to 1 left end of smooth rack, smooth rack 1 top is equipped with fixed plate 8 that is used for fixed cage utensil and smooth rack.

The outer end of the motor 7 is connected with a lead 9, the tail end of the lead 9 is connected with an aviation connector 10, the aviation connector is connected with a program control device to carry out power supply and work control, and the motor at the side end of the sliding table frame is controlled to operate through programming.

As an optimal structure, the connecting rod comprises an upper frame 4 and a lower frame 5, the upper end of the lower frame 5 is provided with a screw hole 12, the upper frame 4 is provided with a through guide groove 11 along the length direction, and after the connecting rod is adjusted to a proper position according to the height of padding, the bolt penetrates through the screw hole and the guide groove and then is locked and fixed.

This embodiment does not restrict the concrete structure of sleep deprivation pole, as a concrete structure example, sleep deprivation pole 6 is the H type, has increased the area of sweeping in the sleep deprivation pole motion process, can cover the inside ground of whole cage utensil, sleep deprivation pole mid portion is equipped with the open slot, 5 tail end of undercarriage inwards buckle the bulge embedding that forms in the open slot and fixed with H type sleep deprivation pole.

The bottom surface of the sliding table frame 1 is provided with a sliding groove, the upper end of the sliding block 2 is provided with a convex block, and the convex block is embedded into the sliding groove, so that the sliding block can move left and right stably along the screw rod and can be prevented from rotating in the moving process.
