Rat single-cage fixing device for electromagnetic exposure experiments

Abstract

The invention discloses a rat single-cage fixing device for electromagnetic exposure experiments. The fixing device comprises a rat cage rack, two door control baffles and an adjusting baffle, wherein a cuboid cavity is defined in the rat cage rack, the two ends, in the length direction, of the cavity are open, and the rat cage rack is provided with an installation through hole communicated with the cavity; the two door control baffles can be movably connected with the two ends of the rat cage rack so as to open and close the two open ends of the cavity, and the door control baffles and the rat cage rack are provided with multiple vent holes making the cavity and the outside communicated; the adjusting baffle can be inserted in the installation through hole in a pluggable mode, and the cavity can be divided into two secondary cavities in the length direction of the cavity when the adjusting baffle is located in the installation through hole. The rat single-cage fixing device can not be limited by small radiation sources and narrow uniform fields, the radiation dosage precision can be improved to 25.45%, and animals can be conveniently put into the device. The device is successfully used in the biological effect research that high-frequency short-wave radiation causes rat brain injuries.

Description

technical field [0001] The invention relates to the technical field of experimental equipment, in particular to a rat single-cage fixation device for electromagnetic exposure experiments. Background technique [0002] With the development of science and technology, high-frequency electromagnetic equipment such as short-wave or microwave is widely used in information, communication, industry and military fields, and human beings are more and more exposed to the electromagnetic radiation environment. Studies have shown that short-term or repeated exposure to electromagnetic fields can cause neurological, reproductive and immune dysfunction, especially harmful to learning and memory functions, which has attracted widespread attention from scholars at home and abroad. [0003] In some related technologies, the strength of the electromagnetic radiation field selected for experimental research, exposure time, test subjects and radiation simulation sources are different, and the nu...

AI Technical Summary

Problems solved by technology

[0003] In some related technologies, the intensity of the electromagnetic radiation field, exposure time, test subjects and radiation simulation sources selected for experimental research are different, and the number of units that can conduct electromagnetic radiation research is limited, resulting in the lack of consistent conclusions in the research results

The rat fixtures used in electromagnetic exposure experiments in the prior art are mostly designed to meet the needs of large-scale radiation simulation sources, and their size is large, which cannot guarantee the effectiveness of animal experiments under the conditions of miniaturization of radiation simulation sources and narrow range of uniform radiation fields. and the existing rat fixing devices all adopt the upper opening type, and the upper baffle is pushed and pulled left and right when sealing, and problems such as pinching the rat tail often occur
