Device for ultrasonic inspection of fixed mouse body

Abstract

The invention discloses a device for ultrasonic inspection of a fixed mouse body. The device comprises a base plate, a left column, a left horizontal shaft, a left rotary gear, a right column, a right horizontal shaft, a right rotary gear, a supporting plate, a left rack, a right rack and a pull rod, wherein a base plate left insert hole, a base plate right insert hole, a left through hole in the base plate and a right through hole in the base plate are formed in the base plate; a first front foot locating clamp is arranged at the side of a first front foot locating through hole under the left rotary gear; a second front foot locating clamp is arranged at the side of a second front foot locating through hole under the left rotary gear; a first rear foot locating clamp is arranged at the side of a first rear foot locating through hole under the right rotary gear; a second rear foot locating clamp is arranged at the side of a second rear foot locating through hole under the right rotary gear. In this way, the mouse body cannot move randomly, but can be rotated for 360 degrees, and then the mouse body can be inspected at different positions, so the inspection time is shorter.

Description

technical field [0001] The invention relates to a device for performing ultrasonic examination and fixing a 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 board in t...

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.
