Description

Technical Field

[0001] The utility model relates to the technical field of animal experiment fixing appliances, in particular to an experimental mouse clamping and fixing device. Background Art

[0002] Experimental mice refer to small rodents used in scientific research and experiments. Common experimental mice include mice and rats. They are usually used in research in fields such as medicine, biology, and psychology. Because they have a short reproductive cycle, are easy to breed, their genomes have been deeply understood, and their physiological and behavioral characteristics are somewhat similar to those of humans, they have become important model animals in scientific research. In pathological research, mostly white mice are used for in-vivo experimental research. White mice are convenient for obtaining samples and have strong vitality. Using them in research can reduce the research cost.

[0003] However, when current laboratories use experimental mice for related experiments, due to improper fixation of the mouse's head during grasping or the experiment process, there are often situations where the mouse turns back and bites the experimenter's hand. Taking "abdominal surgery after intraperitoneal injection anesthesia" as an example, the traditional method is often to pinch the skin at the back of the mouse's neck with the left hand so that the mouse cannot turn back, and then the right hand completes the operation of injecting anesthetic into the abdominal cavity. But at this time, the operator's attention is often on the right hand holding the syringe. Coupled with the fact that the left hand muscles are prone to fatigue after a long operation time, the fixation of the mouse's head is not good, resulting in the experimenter being bitten by the mouse. In addition, even if there is no mistake during injection, when the mouse's head and limbs are fixed on the operating table next, for similar reasons, it is also easy to cause the operator to be bitten by the mouse. On the other hand, the repeated pinching and fixing of the mouse during the experiment can easily cause harm to the experimental animal, affecting the experimental results and efficiency.
