Fixing device for mouse caudal vein injection, suitable for different specifications and convenient to adjust

Abstract

The invention relates to a fixing device for mouse caudal vein injection, suitable for different specifications and convenient to adjust. The fixing device comprises a bearing plate, a top cover, a movable limiting plate and a pressing plate, wherein the top of the bearing plate is covered with the top cover, the right end of the top cover is hinged to the right end of the bearing plate, and a plurality of limiting protrusions are fixedly arranged on the left side of the bearing plate; and a limiting clamping groove cooperating with the corresponding limiting protrusion is fixedly formed in the left side of the top cover, and the left end of the bearing plate and the left end of the top cover are connected in a clamping manner through the limiting protrusion and the limiting clamping groove which cooperate with each other. The fixing device for mouse caudal vein injection, suitable for different specifications and convenient to adjust can be adjusted and fixed according to the body type of a mouse, operation is easy, fixing is firm, the mouse cannot move in the injection process, caudal vein injection is facilitated, the mouse is prevented from biting workers, injection operation is conveniently completed, and a mouse is prevented from being stabbed.

Description

technical field [0001] The invention relates to the technical field of animal medical experimental equipment, in particular to a mouse tail vein injection fixing device suitable for different specifications and easy to adjust. Background technique [0002] Tail vein injection of mice is commonly used in drug screening and acute toxicity tests. The traditional method is that the experimenter grabs the mouse by hand and injects it. The injection process is very time-consuming and labor-intensive. Because the mouse is a living animal, and the mouse is small in size, agile, uncontrollable, and sometimes may even bite the experimenter. personnel. Most of the existing traditional mouse tail vein injection fixators are cylindrical with an opening at one end and can be closed, and the other end can be ventilated. When injecting, the mice are stuffed into the cylinder, and one end of the cylinder is closed. The end has an opening to expose the tail of the mouse for tail vein inject...

AI Technical Summary

Problems solved by technology

[0003] Yet existing mouse tail vein injection fixator also has the following disadvantages: a. It is troublesome to use, first open the engaging parts, unscrew the nut, take off the movable part, pull the mouse into the fixing chamber upside down, and then install it. Go up the movable part, tighten the nut, and then close the engaging parts. The operation is cumbersome and time-consuming; b. Difficult to clean, the mouse defecates in the holder, and the inside of the holder is difficult to clean, and it is easy to get dirty and smelly; c. It cannot be adjusted according to the size of the mouse Adjust the size of the fixer, often there is insufficient fixation or too tight fixation, which may easily cause the injection operation to be unable to be completed or the mice to be stabbed
