Miniature adjustable directional irradiation device for animal experiment

Abstract

The invention relates to an irradiation experiment device, in particular to a miniature adjustable directional irradiation device for an animal experiment, which is small in volume, can control the dosage, and can completely and directionally irradiate. The miniature adjustable directional irradiation device comprises a bracket (1), a shielding body and an irradiating assembly; the shielding body comprises a shielding barrel (2) and a shielding rotary cage (3); the irradiating assembly comprises a plurality of irradiation sources (4), a directional box (5) and an irradiation barrel (6); the shielding barrel (2) is fixed on the bracket (1); the shielding rotary cage (3) capable of rotating is arranged inside the shielding barrel (2); the directional box (5) is embedded on the inner wall of the shielding barrel (2) and made of an irradiation shielding material; the irradiation sources (4) are uniformly filled in the directional box (5); collimators (7) which are respectively in a through hole shape are respectively arranged corresponding to the irradiation sources (4); the irradiation barrel (6) is sleeved inside the shielding rotary cage (3); and a transmission gap (301) is arranged at one side of the irradiation barrel (6), corresponding to the collimators (7), and a transmission opening (302) is arranged at the other opposite side of the irradiation barrel (6).

Description

Technical field [0001] The invention relates to an irradiation experiment device, in particular to a small adjustable directional irradiation device for animal experiments. Background technique [0002] Animal experimentation refers to scientific research using animals in a laboratory in order to obtain new knowledge about biology, medicine, etc. or to solve specific problems. The ultimate goal of the development of experimental animal science is to use the research on the life phenomenon of animals, and then apply it to humans, explore the mysteries of human life, control human diseases and aging, and extend human life. With the rapid development of medical biological sciences, it is recognized that pollution problems have not only become major social problems for food, population, and the elderly, but also involve the survival of animals living on the earth, such as industrial pollution, food pollution, and drug toxicity And so on, all directly affect human health.

Problems solved by technology

However, there are two kinds of existing irradiation devices: one is a gamma ray irradiation device, and the other is an electron accelerator irradiation device (divided into an X-ray irradiation device and an electron beam irradiation device, mainly an electron beam irradiation device). device); but its related devices and equipment that can meet the adjustment operation and orientation requirements are huge in size. For general animal experiments, not only is it inconvenient to use, but also the cost is too high. Moreover, the directional irradiation cannot be realized in the existing experimental technology, and the full-irradiation experiment is used, which cannot complete some animal experiments with high requirements, and also meets the requirements of medical animal experiments.
