Problems solved by technology

[0003] Most of the existing mouse fixing devices are made of metal materials. Although the mice can be firmly fixed, because the temperature of the metal material itself is lower than room temperature, it will stimulate the mice when using it to fix the mice, which is not conducive to the experiment. , and the cost of metal materials is relatively high, and it is not easy to manufacture
The existing mouse fixation device also has a plastic material fixer, but the mouse needs to be fixed under anesthesia, which has the disadvantages that the mouse is not firmly fixed in an awake state, and it is not easy to disassemble and clean
In addition, the existing fixator does not have a special head fixing structure, which is not conducive to the electrical stimulation experiment of the mouse brain

Abstract

The invention relates to an experimental animal fixing device, in particular to a fixing device for mouse brain electrophotoluminescence in the waking state. The fixing device comprises a fixing cover, a fixing belt and a fixing mechanism. The fixing mechanism comprises a fixing panel, a fixing piece, a rotatable rod and fixing hook nails. The fixing piece is arranged on the fixing panel. The rotatable rod is fixed to the fixing panel through the fixing piece. The hook nails are arranged on the two side faces of the fixing panel. An arc fixing opening is formed in the middle of the rotatable rod. The fixing cover is arranged on the fixing panel. The fixing belt is bound on the fixing hook nails to fix the fixing panel and the fixing cover. The mouse fixing device is simple in structure, convenient to assemble, easy to operate, low in cost, convenient to manufacture and capable of effectively fixing a mouse when the mouse is kept in the waking state; the fixing cover, the fixing mechanism, the fixing belt and the base are detachable and easy to clean and disinfect.

Description

technical field [0001] The invention relates to an animal fixing device for experiments, in particular to a fixing device for electrical stimulation of the mouse brain in an awake state. Background technique [0002] Mice are commonly used experimental animals in medical research. The research on electrical stimulation of mouse brain has certain research on many neurological disorders such as stroke, movement disorder, Parkinson's disease, Alzheimer's disease, depression, schizophrenia, etc. value. When conducting brain electrical stimulation experiments on mice, it is often necessary for the mice to operate in an awake state, and to stimulate with direct current, alternating current, and random polarity current to change the excitability of the cerebral cortex. However, due to the small size of the experimental mice, flexible movements, and difficulty in fixing when awake, the electrodes are easy to loosen or slip off, resulting in changes in multiple parameters such as el...
