Description

Technical Field

[0001] The utility model relates to a spliced ​​sleep deprivation mouse cage and belongs to the technical field of animal experimental equipment. Background Art

[0002] Sleep deprivation is a commonly used experimental method to study the effects of sleep on organisms. This method limits or deprives animals of their sleep time to observe the effects of sleep on their behavior, physiology, and cognitive function.

[0003] In experiments, researchers use specific devices or methods to deprive animals of sleep. For example, they can force animals to stay awake by placing them on a rotating platform or installing a horizontally moving lever in their cage. Researchers can also use other methods, such as Curling Prevention by Water (CPW), electrical stimulation, noise, or drug intervention, to deprive animals of sleep.

[0004] Traditional sleep deprivation cages have the following shortcomings:

[0005] 1. Poor sleep deprivation: Traditional mechanical interference cages may cause mice to ignore mechanical interference and fall asleep when they are extremely sleepy. Ordinary water-blocking cages can prevent mice from curling up. If multiple mice are kept in one cage at the same time, the mice may cuddle with each other and fall asleep, which will not effectively deprive the mice of sleep.

[0006] 2. Difficulty in distinguishing wires: Sleep deprivation experiments often require monitoring the sleep status of mice by connecting them with wires in order to measure EEG and EMG. Traditional mechanical interference with mouse cages may cause wire entanglement, making it difficult to distinguish and separate them.

[0007] Existing water-blocking curl-up sleep deprivation cages have the following disadvantages:

[0008] 1. Difficulty in controlling the water level: Ordinary water prevents the bottom of the curled squirrel cage from being sealed. It is difficult to accurately control the water level when injecting water. It is impossible to maintain consistent water level conditions in each squirrel cage and scientifically control the variables.

[0009] 2. Inconvenience in cleaning the cage: The cage of the existing cage device is fixed on a fixed plate, so that when the excrement of rats and mice inside the cage needs to be cleaned, additional tools are needed for auxiliary operation, and the rats and mice need to be taken out, which makes the cleaning operation inconvenient.

[0010] Therefore, there is an urgent need in the art for a device that can solve the shortcomings of existing sleep deprivation mouse cages, such as poor sleep deprivation and difficulty in distinguishing wires, as well as the difficulty in controlling the water level and inconvenience in cleaning the existing water-blocking curled sleep deprivation cages, so as to provide a more scientific, hygienic and convenient mouse breeding device for sleep deprivation-related experiments.

In this embodiment, the biological entrance 14 is preferably a circular notch provided in the middle of the square cage body 1 for placing mice and accommodating wires. Taking the square cage body 1 with a length × width × height of 100 mm × 100 mm × 120 mm as an example, the square notch 15 is preferably a notch with a length × width × height of 25 mm × 25 mm × 50 mm. When one side of any four square cage bodies 1 with square notches 15 is spliced ​​together, a placement groove 2 connecting the inner cavities of the four square cage bodies 1 is formed, and the diameter of the circular notch is preferably 60 mm.

[0038] Furthermore, the square cage body 1 includes a cage body 11, and a square notch 15 is opened on the cage body 11, that is, when four cage bodies 11 are assembled, any four square cage bodies 1 can be assembled to form a placement slot 2 to achieve the purpose of communication.

[0039] Reference Figure 1-Figure 33, and the food box 4 is provided with a slot 31. In this embodiment, the slot 31 is set to fit four cage bodies 11. A plurality of square cage bodies 1 can be spliced ​​and inserted into the slot 31, and a flow gap 5 is formed between the bottom wall of the square cage body 1 and the bottom wall of the tray 3. A water inlet 32 ​​is formed on the side wall of the tray 3. When conducting an experiment, the experimenter pours clean water into the tray 3 through the water inlet 32.
