Abstract

The invention provides a fixing device for an external exposure radiation experiment of the buccal mucosa of mesocricetus auratus. The fixing device comprises a clamping table, a clamping ring, a lower rack A, an upper rack A, a rack shaft, an upper rack B, an elastic component, an upper hand ring, an upper plate, a lower hand ring, a lower plate, an axle hole, a lower rack B and a gap, wherein the elastic component runs through the upper and lower plates to achieve an effect of supporting the upper and lower plates; and one end of the upper plate is protruded downward to form a serrated edgeand is placed on the clamping table. The fixing device can completely implement seizing and fixing on buccal mucosa tissues after the buccal mucosa of mesocricetus auratus is turned outward, and the serrated edge is safe and steady. The device is convenient and efficient in operation by utilizing the principle of a spacing clip; damage on a target tissue can be reduced by utilizing the elasticityof the spring and the material advantages of the clamping table; and the whole fixing device is smart and light in design, and can be transferred and irradiated together with an experimental object, so that irradiation damage of an operator can be prevented. The fixing device fills the blank of experimental equipment in the field.

Description

technical field

[0001] The invention belongs to the field of auxiliary equipment for animal experiments, and relates to a fixing device for a golden hamster oral buccal mucosa external exposure radiation experiment, which is suitable for the fixing technology of the golden hamster oral mucosa external exposure radiation experiment. Background technique

[0002] Golden hamster (hereinafter referred to as hamster), scientific name Mesocricetus auratus, English name Golden hamster. Hamsters have cheek pouches in their mouths that other rodents do not have. They can hide food on both sides of their gills and spit it out in a safe place for preservation. Therefore, hamsters have the largest proportion of oral mucosa area in other mice. Golden hamster is an important member of experimental animals, and ranks fourth among rodents after mice, rats and guinea pigs in terms of usage volume and usage range. Hamsters are susceptible to tumor-inducing viruses. Tumor tissues are easily ...
