Description

Technical Field

[0001] The utility model relates to the fields of toxicology and pharmacodynamics detection and research, in particular to a fixing device for experimental mammals, specifically used for fixing rabbits. Background Art

[0002] Animal experiments are currently a commonly used method to verify drug effects. Rabbits are a commonly used experimental animal. For animal experiments using rabbits, it is often necessary to turn the rabbits' body position so that they are in a supine position during the experiment to facilitate vaginal and bladder administration, flushing, and other operations. However, rabbits are strong and easily frightened. Even slight stimulation can cause them to struggle violently. Therefore, when performing vaginal or bladder catheterization on rabbits for drug administration, not only does it require multiple people to operate, but it is also easy to injure the vaginal or bladder mucosa, affecting the test results.

[0003] The vaginal opening of a domestic rabbit is located below the anus and close to it. If the rabbit is not turned over and placed in a supine position, not only will intubation be difficult, but it will also be easily contaminated by feces. At the same time, turning the rabbit over manually will cause violent struggles and may be easily injured by sharp rabbit claws. On the other hand, due to the rabbit's strong struggling force, the operator often needs to grasp and fix it with force, which may easily cause the rabbit to sprain. Utility Model Content
