Experiment box for animal toxicology experiment and using method thereof

technical field

The invention relates to the technical field of animal toxicology experiments, in particular to an experimental box for animal toxicology experiments.

Background technique

Animal toxicology experiment is an experimental method to clarify the toxicity and potential harm of a certain chemical by observing the toxic reaction of animals after giving specific substances. The safety of chemical products plays an important role in evaluating the toxicological safety of the use of chemical substances by humans, and providing a theoretical basis for formulating preventive measures and hygienic standards. Common experimental animals include rats and mice. Because of the simplicity of feeding, there are many The primary choice for biomedical experiments is usually bred in a breeding cage, which is convenient for observation after the experiment. During the experiment, the rats or mice are first taken out of the breeding cage and placed on the experimental operation platform for experimental operations. During the experiment, it is necessary to give Rats are fed or injected with specific drugs, and the rats will show resistance when they are frightened. In order to ensure the smooth progress of the drug injection, it is necessary to use a fixture or manpower to fix the animal first, and then inject the drug. The manual fixation method requires the cooperation of at least two people Completing the operations of fixation and drug injection of rats and mice consumes a lot of human resources.

Especially for the experimental rats, the immobilization device fixes the limbs of the experimental rats through straps, but only binding the limbs of the experimental rats, the body of the experimental rats will still show resistance movements, resulting in a relatively low fixation effect. Poor, it affects the progress of the experiment, and the experiment needs to be injected several times, and the experimental rats need to be put back into the breeding cage after each injection, so the experimental rats need to be transferred frequently, because the function of the breeding cage is relatively single , It is also necessary to equip a special experimental operation platform when conducting experiments, which increases the cost of the experiment and is not conducive to the progress of the experiment, and the effect of fixing the limbs is poor, which affects the progress of the experiment and brings inconvenience to the experimenters.
