Technical Field

The invention belongs to the technical field of medical experimental instruments, and particularly relates to a restraint bag for a murine animal experiment.

Background

The murine animal has high gene similarity with human, and is widely applied to research, teaching and the like in the fields of biology, medicine and veterinary medicine. As the murine animals are easy to feed, have high reproduction rate and low cost, high hereditary purity, metabolic type and physiological and pathological conditions close to those of human beings and the like, the murine animals are used for experiments, have high efficiency and small individual difference, and are convenient for parallel observation of experimental results, so the murine animals become the most important experimental animals. In biomedical research, it is necessary to select suitable subjects among healthy murine animals, of which rats and mice are the most commonly used experimental animals, according to the purpose of the research and the physiological characteristics of the experimental animals; however, in the experimental studies of immunology and otology, guinea pigs are often selected as the experimental animals.

In the experimental study, the experimental operation performed in the awake state of the mouse was mainly performed on the head, abdomen, four limbs and tail of the mouse. The important acupoints are distributed on head, abdomen and limbs, and are also the common points for basic research of animal experiment. In the experimental process, the binding mode and the fixing effect on the mouse determine the success or failure of the experiment and the accuracy of the scientific research result. Therefore, effective constraint on the mouse is the premise of smooth implementation of animal experiments, the effective constraint mode can ensure the smooth implementation of the experiments, avoid the stress response caused by over stimulation on the mouse to influence the accuracy of the experimental results, and can also ensure the safety of researchers in the experiments. For example, when a rat or a mouse is subjected to experimental operation, the animal can avoid or bite the rat or escape from the experimental table due to instinct, so that the experimental operation cannot be smoothly performed, higher requirements are provided for a mouse binding mode and a mouse fixing effect, and a binding device capable of fully exposing acupuncture points and ensuring experimental implementation is required. In the prior art, the restraint device for the experiment of the murine animals is limited to the head of the mouse at most of the parts for experimental research, has poor restraint and fixing effects and is inconvenient to operate the abdomen and the four limbs of the mouse. Therefore, the restraint bag with more comprehensive functions is developed, experimental research is carried out on more parts of the mouse, and the restraint bag has important significance for promoting research progress in the aspects of medical treatment, heredity, biological products and the like.
