Adjustable fixator for mouse tail-vein injection

Abstract

The invention relates to the field of animal medical experiment instruments, in particular to an adjustable fixator for mouse tail-vein injection, comprising a base, a tail-holding slider, a cold light, a fixing barrel, an adjusting cover, a connection device and a retainer; the base is provided with a rectangular groove; the tail-holding slider is arranged in the rectangular groove; the cold light is mounted on the tail-holding slider; the fixing barrel is mounted on the upper surface of the base; the adjusting cover is mounted in the front of the fixing barrel through the connection device;the retainer is mounted at the rear end of the fixing barrel. The adjustable fixator for mouse tail-vein injection allows a mouse to be precisely fixed, allows its size to be adjusted according to thebody size of the mouse, and allows the mouse state to be observed to ensure injection precision.

Description

technical field [0001] The invention relates to the field of animal medical experiment equipment, in particular to an adjustable mouse tail vein injection fixator. Background technique [0002] In the scientific research fields of physiology, biochemistry, pharmacology, medicine, etc., mice are usually used as research objects. During the research process, tail vein injection of mice is often required. Because the tail veins of mice are thinner, it is more difficult to inject tail veins in medical experiments. The traditional method is that the experimenter grabs the mouse by hand and injects it. The existing device cannot adjust the size of the fixer according to the size of the mouse, and there are often situations where the fixation is insufficient or too tight. If it is not fixed or the fixation is not good, the tail of the mouse will swing during the injection process, the injection operation cannot be completed or the mouse will be stabbed, and even the experimenter w...

AI Technical Summary

Problems solved by technology

The traditional method is that the experimenter grabs the mouse by hand and injects it. The existing device cannot adjust the size of the fixer according to the size of the mouse, and there are often situations where the fixation is insufficient or too tight

If it is not fixed or the fixation is not good, causing the tail of the mouse to swing during the injection process, the injection operation cannot be completed or the mouse will be stabbed, and even the experimenter will be bitten by the mouse.

The existing device also has the disadvantage of not being able to observe the state of the mouse in real time, and the mouse may die due to improper observation during the injection process

The traditional injection method is difficult for colored mice (black or brown-black) to identify the position of the tail vein blood vessel, the injection is difficult, affects the injection efficiency, and cannot accurately observe whether the needle enters the blood vessel, and the injection accuracy is low
