An experimental rodent fixation device

Abstract

The invention relates to the technical field of experimental equipment, and discloses a rodent fixing device for experiments, which includes a base plate, a cylinder and a box are fixedly installed on the top of the base plate, the cylinder communicates with the inside of the box, and the cylinder One end of the body is fixedly installed with a cover, and both sides of the cylinder are slidably connected with a slide bar, and the end of the slide bar extending to the outside of the cylinder is fixedly connected with a pressure plate, and the slide bar extends to the inside of the cylinder A connecting plate is fixedly connected to one end of the two connecting plates, a clamping seat is fixedly connected to the opposite sides of the two connecting plates, a supporting spring is fixedly connected to the opposite side of the two pressing plates, and the other side of the supporting spring One end is fixedly connected with the outer wall of the cylinder. The invention can grasp and fix the mice in the awake state, can effectively prevent the problem that the mice will bite the experimenters, improves the safety of the experimenters when using, and has simple structure and convenient operation.

Description

technical field [0001] The invention relates to the technical field of experimental instruments, in particular to an experimental rat fixing device. Background technique [0002] Rats are one of the most commonly used animals in medical experiments and are widely used in research experiments in advanced nervous system, endocrine, digestion, surgery, nutrition, etc. The easily irritated rat bites the hand, and it is difficult to prevent even wearing protective gloves, which increases the difficulty of the experiment, affects the accuracy of the experiment, and prolongs the experiment time. In order to solve this problem, some people wrap it with cloth thickly during the experiment, and some put it into a glass container with a rubber stopper at the bottom and a ventilation hole at the top, which cannot fundamentally solve the problem.

Problems solved by technology

[0002] Rats are one of the most commonly used animals in medical experiments. They are widely used in research experiments on the advanced nervous system, endocrine, digestion, surgery, nutrition, etc. Rats that are easily irritated bite their hands, and it is difficult to prevent even wearing protective gloves, which increases the difficulty of the experiment, affects the accuracy of the experiment, and prolongs the experiment time

In order to solve this problem, some of them wrapped it thickly with cloth during the experiment, and some put it into a glass container with a rubber stopper at the bottom and a vent hole at the top, which could not solve the problem fundamentally.

[0003] The existing patent CN99218133.X discloses a medical laboratory rat fixer to solve the above problems, but the device has many operating steps and is inconvenient to use, and when the rat is awake, there are disturbances, biting and struggling It is not easy to fix, and it is generally difficult to operate when injecting drugs directly into the tail of rats or taking blood samples. It is difficult to effectively guarantee the safety of experimenters. Even if the existing rat fixation device is used, it is inconvenient to use. 1. The structure is complicated. When using it, it is necessary to fix the limbs of the rat in turn, and it is easy to be scratched or bitten during the fixation process. At present, no ideal device for fixing the rat in the awake state has been found.
