Description

Technical Field

[0001] This utility model relates to the field of experimental equipment technology, and in particular to an animal behavior training device based on an air-floating ball before magnetic resonance imaging. Background Technology

[0002] In the field of magnetic resonance imaging (MRI) research, conducting experiments with awake animals has extremely important scientific value. When animals are awake, their neural activity can be more accurately reflected, which lays the foundation for subsequent behavioral research. Because the noise generated during MRI can cause strong auditory stimulation to animals, triggering intense reactions, such intense reactions may lead to increased heart rate, elevated blood pressure, increased anxiety, and even affect the normal pattern of neural activity. Untrained animals may also exhibit violent movements due to noise during MRI scans, which can affect image quality and the success or failure of the experiment. Therefore, acclimatizing animals to the noise during MRI scans before performing MRI is an important step.

[0003] Existing pre-training devices for magnetic resonance imaging typically use fixed platform devices. Fixed platform devices lack freedom of movement during training, which restricts the animal's movement and is detrimental to training. Utility Model Content

[0004] To address the lack of freedom of movement in existing training devices, this invention proposes a pre-magnetic resonance imaging (MRI) animal behavior training device based on an air-floating ball.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model proposes a pre-MRI animal behavior training device based on an air-floating ball, comprising a support mechanism and a float mechanism, wherein:

[0007] The support mechanism includes a support platform with an air-float ball base slot. The float mechanism includes an air-float ball base disposed in the air-float ball base slot. The air-float ball base has a semi-circular groove with an air-float hole at the bottom. An air-float ball is loaded in the semi-circular groove. The bottom of the air-float ball base has multiple air inlets communicating with the air-float hole. An external blower supplies air to the air-float hole through the air inlets and drives the air-float ball to suspend, thus achieving multi-degree-of-freedom training.

[0008] Furthermore, it also includes a head column fixing mechanism, which includes a head column fixing frame disposed on the front side of the air float base slot, the head column fixing frame being fixedly connected to the support platform, the head column fixing frame being provided with a head column slot, and the head column being fixed in the head column slot.

[0009] Furthermore, it also includes a monitoring mechanism, which includes functional frames disposed on the left and right sides of the air-float ball. The functional frames are fixedly connected to the support platform. A camera clip is disposed on the top of one of the functional frames, and a mini camera is embedded in the camera clip. Both of the functional frames are provided with silicone tube grooves for fixing silicone tubes on their sides.

[0010] Furthermore, it also includes a training box, which includes an outer shell, with a top cover and a side cover respectively provided on the top and side of the outer shell, and the top cover and the side cover are rotatably connected to the outer shell.

The multiple screens are arranged in sequence to form a whole and surround the outside of the air-float ball by 180 degrees.

[0017] The beneficial effects of this utility model are:

[0018] (1) The animal behavior training device based on air-floating ball proposed in this utility model uses an external blower to ventilate the air-floating hole through the air inlet pipe and drive the air-floating ball to suspend. The limbs of the small animal can move freely on the air-floating ball without restriction, and the training effect is better.

[0019] (2) The animal behavior training device based on air-floating ball proposed in this utility model improves the degree of freedom of movement by using the air-floating mechanism, while simulating the real natural environment with three screens and speakers.
