Description

Fixing frame for guinea pigs Technical Field The utility model belongs to the field of experimental animal equipment, and particularly relates to a guinea pig fixing frame. Background In scientific research and teaching experiments, particularly in research and development of medical instruments and biological medicines, a great deal of basic research and experiments are necessary, and the research and experiments are difficult to perform in-vivo experiments of human beings due to strict limits of laws and ethics, and can only be performed through in-vivo experiments of experimental animals, and since the gene sequences of guinea pigs are very similar to those of human beings, the pharmaceutical experiments mostly adopt the guinea pigs as experimental animals. Intravenous injection, blood sampling, skin irritation and the like are common experimental means for guinea pigs, and the guinea pigs are required to be stably fixed at first in any experiment so as to ensure the smooth progress of the experiment. However, the guinea pig is very good in nature, the claw of the guinea pig is particularly sharp and difficult to control, the experimental operator is extremely easy to scratch, the experimental difficulty is greatly increased, the experimental efficiency is reduced, and when the experiment is carried out after the fixing, different parts of the guinea pig need to be operated, but the fixed guinea pig cannot move, the experimenter needs to place the guinea pig at different heights according to the operation requirement, or the experiment position is converted for operation, so that the experiment is more complicated.
