Special device for fixing mouse during ultrasonic examination

Abstract

A special device for fixing a mouse during ultrasonic examination comprises a bottom plate, a left stand column, a left cross shaft, a left rotating gear, a right stand column, a right cross shaft, a right rotating gear, a supporting plate, a left rack, a right rack and a pull rod, wherein a left bottom plate insertion hole, a right bottom plate insertion hole, an upper left bottom plate through hole and an upper right bottom plate through hole are formed in the bottom plate; a first front foot positioning clamp is arranged beside a first front foot positioning through hole in the lower part of the left rotating gear; a second front foot positioning clamp is arranged beside a second front foot positioning through hole in the lower part of the left rotating gear; a first rear foot positioning clamp is arranged beside a first rear foot positioning through hole in the lower part of the right rotating gear; a second rear foot positioning clamp is arranged beside a second rear foot positioning through hole in the lower part of the right rotating gear. Accordingly, a mouse body cannot swing at will and can be rotated by 360 degrees, different positions of the mouse body can be examined, and the examination time is shorter.

Description

technical field [0001] The invention relates to a device specially used for ultrasonic examination and fixation of mouse body. Background technique [0002] In the field of life science research, basic research is an indispensable link. In basic research, mice are one of the most common experimental animals. With the continuous advancement of overall scientific research, the research on mice is not limited to biochemical detection, and some inspection methods applied to human routine medical treatment are also Among them, ultrasonography is one of them. In the process of ultrasound examination, there is a relatively obvious feature, that is, different postures such as the heart, liver, kidney and other animals that need to be examined are taken in different positions such as lateral position, supine position, and prone position. [0003] At present, when ultrasonic examination of rat organs is performed, the rat is under anesthesia, and the limbs are usually fixed on a boa...

AI Technical Summary

Problems solved by technology

However, these two positions can barely meet the ultrasonic examination of organs such as the liver or kidney. Once the anatomical structure and position of the rat's organs vary, it will be troublesome to change other positions and effectively fix them; When examining organs, the left side lying position is often required, and obviously these two positions are also inappropriate; in addition, when multiple organs need to be examined, it is necessary to change positions frequently

When the above situation exists, the previous method of fixing the mouse obviously cannot fully meet the needs of the scientific research work. It is often necessary to fix the limbs on one side of the mouse, and an experimenter is responsible for holding the limbs on the other side of the mouse in the air. This is not easy to fix and inspect, and changing different positions significantly prolongs the time of ultrasonic examination, and at the same time increases the risk of biting the operator due to insufficient anesthesia dose or uneven pulling force in the experiment.
