Abstract
Description
Technical Field
[0001] This utility model relates to the field of animal experimental box technology, and in particular to an animal experimental box system. Background Technology
[0002] The open field test (OFT) is a commonly used method in animal behavior testing. For example, it can detect spontaneous activity and movements in mice after drug administration, and is a method for evaluating the behavior, motor agility, and stress levels of experimental animals under the influence of drugs. The OFT has a wide range of applications, spanning small animal behavioral research and extending to neurological and pharmacological research. Taking antipsychotic drugs as an example, OFT is generally used to detect drug efficacy and side effects. Currently, OFT is often used as a control to reflect various spontaneous behaviors in experimental animals. Because of its simple operation and abundant data, a single experiment can quantitatively evaluate an animal's spontaneous activity, behavior, and anxiety or depression, making it widely used in drug research and development.
[0003] Open-box experiments (OFT) typically use specialized animal testing chambers, such as standard mouse cages, containing one or more mice. During pharmacological studies, mice are fed or injected with appropriate drugs, and their specific behaviors and postures are observed. Statistical results are compiled over a certain period to understand the drug's effects on the animals, pharmacokinetic behavior, and side effects, providing a relatively accurate and objective assessment of drug efficacy. Systems with automated analysis capabilities are now available on the market. These systems utilize high-definition cameras to record and identify various animal behaviors in real time, generating corresponding reports, reducing manual workload, and improving the accuracy of observations. However, existing animal testing chamber systems have at least the following drawbacks:
[0004] The experiment requires observing the animal's behavior from all sides. Therefore, the observation box should avoid obstructing the observation of the animal's surroundings as much as possible. Existing animal observation boxes need further optimization.
[0005] The effective shooting position for animal experiments is at the same level as the animal observation box. If the installation distance is too close, the image will be blurry, while if the camera is too far away from the animal observation box, it will be outside the range of the experimental box. Therefore, how to arrange the camera to effectively image the animal experimental box needs further optimization. Utility Model Content
[0006] The technical problem to be solved by this utility model is to provide an animal experimental box system that makes the animal experimental box structure reasonable, facilitates the observation of animal behavior and obtains effective and clear images.
