Experimental rat holder

Abstract

The invention discloses an experimental rat holder which is a suspension or traveling support type experimental rat holder, comprising a base, a plug bush, a suspension rack, a traveling support, a rat holding rack, a drum type rat holding box, an operating desk and a tail pressing rack, characterized in that: the plug bush is fixed at the front part of the base, the suspension rack or the traveling support is inserted into the plug bush, the suspension rack or the traveling support fixes the rat holding rack or the drum type rat holding box, the operating desk is fixed at the back part of the base, the tail pressing rack is arranged on the operating desk, lugs are fixed to the operating desk, two lugs are flexibly connected with one end of the tail pressing rack through a small axis pin, a rubber pad is fixed at the tail pressing part of the tail pressing rack, an adjusting screw and a gravity nut are assembled on the tail pressing rack, and a tempering heater is fixed to the operating desk provided with a moving platform. The experimental rat holder provided by the invention can enable the rattail vein to dilate and keep in a horizontal straight line, thus facilitating needle insertion and injection, reducing the difficulty in rattail intravenous injection, and enabling animal experiments to be performed smoothly.

Description

technical field [0001] The present invention relates to a kind of experimental animal nude mouse, small white mouse, rat, black mouse etc. that is used in the research of medicine, food etc. to inject medicine into the tail vein or take blood from the artery to take necessary control of the experimental mouse to make it A kind of experimental mouse fixer that keeps a certain part in a static state and is convenient for experimenters to operate. Background technique [0002] At present, most experimenters use a cylindrical mouse box holder or press the tail of the mouse with the edge of the box, and then inject drugs into the tail vein of the mouse. However, the mouse fixed in the cylindrical mouse box often struggles and produces a reaction force on the tail to move, which is not convenient for tail vein injection, and there is no operating plane for the tail, so the operation is very inconvenient, and the intravenous injection is often stopped and the operation is repeated;...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to overcome the inconvenient operation of rat tail vein injection in the existing experimental mouse fixer, and often make the intravenous injection stop and repeat the operation, and often damage the rat tail vein. The present invention provides a kind of experimental mouse fixer, It can keep the rat tail vein in a straight line, reduce the difficulty of intravenous injection, facilitate operation and use, reduce the damage to the rat tail vein, make the animal experiment go smoothly, and make the experimental results more scientific
