Fixing device capable of positioning rodent for electromagnetic radiation exposure

Abstract

The invention discloses a fixing device capable of positioning a rodent for electromagnetic radiation exposure. The fixing device comprises a positioning bottom plate and a fixing cabin, wherein rulers in the X direction and the Y direction are arranged on the positioning bottom plate; the fixing cabin is respectively and adjustably arranged on the positioning bottom plate in the X direction and the Y direction; the fixing cabin comprises a cabin body, a fixed baffle plate, a movable baffle plate and a fixing element; the fixed baffle plate is arranged at one end of the cabin body; the movable baffle plate is slidably arranged on the cabin body in the axial direction; a placing cavity with the adjustable axial length is defined among the cabin body, the fixed baffle plate and the movable baffle plate; a tail hole through which the tail of the rodent passes is formed in the movable baffle plate; and when the positioning element is connected between the movable baffle plate and the cabin body, the axial length of the placing cavity is fixed. The fixing device provided by the embodiment of the invention has the advantages that the concrete space position of the rodent in an electromagnetic radiation field can be precisely determined; and the small deviation between the electromagnetic radiation dosage received by the rodent in experiments and the expected dosage is ensured.

Description

technical field [0001] The invention relates to the technical field of electromagnetic radiation, in particular to a fixation device for positioning rodents used for electromagnetic radiation exposure. Background technique [0002] With the continuous development of information technology, the impact of electromagnetic radiation on health has attracted widespread attention. Studying the biological effects of electromagnetic radiation and its mechanism can lay the foundation for the prevention and treatment of electromagnetic radiation damage and targeted radiation protection. The establishment of rodent injury models induced by electromagnetic radiation is an important basis for the study of the biological effects of electromagnetic radiation. [0003] The existing rodent fixtures used in electromagnetic exposure experiments have no spatial positioning function, and usually use a cage with a cuboid cavity with a movable baffle to fix rodents, and adjust Baffles control the...

AI Technical Summary

Problems solved by technology

[0004] 1) The existing electromagnetic exposure rodent fixation device cannot determine the specific spatial position of the rodent in the electromagnetic radiation field, which causes great difficulties for accurate radiation dose estimation

[0005] 2) The cuboid-shaped cage used in the existing electromagnetic exposure rodent fixation device cannot fully fit the body shape of the rodent, resulting in the experimental animal still having room to move in the cage, which eventually leads to the electromagnetic radiation dose of the experimental animal being lower than the expected dose. Variation between doses

[0006] 3) The adjustable range of the plug-in baffle used in the existing electromagnetic exposure rodent fixation device is too small, and the applicable experimental animal size is very limited
