Embodiment Construction

[0023] In the process of research on the biological effects of radiation, cobalt-60 or other radiation sources are often used to irradiate mice with different doses, but the accuracy of the radiation dose directly affects the reliability of the experimental results. The present invention divides the concentric circle chassis into 12-16 mouse compartments with partitions, and the narrow space formed by the mouse compartment and the top cover can accommodate the mice, so that the mice cannot move freely in it, and the raised card can ensure the concentric circle There is a certain gap between the chassis and the top cover, and the size of the gap can be adjusted by adjusting its height, so that mice of different sizes can be fixed and the mice can breathe unobstructed. The invention can irradiate 12-16 mice at one time, and because the chassis is designed as concentric circles, it can realize uniform irradiation on mice, improve the efficiency of irradiation on mice, and ensure t...

Abstract

The invention discloses a mouse irradiation disc fixing device. The mouse irradiation disc fixing device comprises a base disc (1) and a top cover (4) arranged on the base disc, the base disc (1) is of a concentric circle structure formed by a round outer edge and a round inner edge, a plurality of partition boards (9) are arranged between the round outer edge and the round inner edge to divide the base disc (1) into mouse cells of the same size, the round outer edge of the base disc (1) is evenly provided with a plurality of raised clamps (11) with adjustable height, the top cover (4) is provided with an elliptical mouse passing hole (8), the position of the top cover, which is adjacent to the mouse passing hole (8), is provided with a push-pull type baffle (6) which plays a sealing role. Due to the fact that the height of the raised clamps can be adjusted to enable the mouse cells to have gaps, the mouse irradiation disc fixing device can guarantee that mice can breathe normally during experiments, and improves the accuracy of irradiation dose; can meet the requirement of simultaneously irradiating one group or a plurality of groups of animals to improve experiment efficiency and to reduce experiment costs. Besides, main body components of the mouse irradiation disc fixing device are easy to disassemble, so that cleaning is facilitated.

Description

technical field [0001] The invention relates to a mouse irradiation fixation device used in experiments, in particular to a disk fixation device used in the experiment process of mouse cobalt-60 radiation or other radiation sources. Background technique [0002] In the course of research on the biological effects of radiation, it is often necessary to conduct mouse irradiation experiments. When carrying out mouse irradiation experiments, it is usually necessary to put mice of the same group or the same irradiation dose into a relatively small container and then receive irradiation. [0003] However, because the container is generally relatively large, the mice can move freely in it and cannot be completely fixed, and when irradiated, the absorbed dose of the mouse is inversely proportional to the square of the distance, so the distance between the mouse and the radiation source plays a role here. Very large effect, if the mice cannot be relatively fixed, it cannot guarantee...
