Laboratory rat tail vein injection fixator

Abstract

The invention discloses a laboratory rat tail vein injection fixator, which comprises a base and a fixing barrel, wherein the fixing barrel can be slidably inserted into the base for fixation, the ground of the base is provided with a double-sided adhesive silica gel layer, and the fixing barrel is composed of a bottom plate, an arc-shaped upper cover and a bolt; the upper cover can completely cover the bottom plate, the upper cover is in shaft connection with one side of the bottom plate, so that the upper cover can be opened upwardly relative to a shaft, and the other side of the upper coverlimits the opening of the upper cover by means of the removable bolt; and a circular hole is formed in the tail part of the fixing barrel, and is used for allowing the tail of a laboratory rat to extend out for facilitating injection. The laboratory rat tail vein injection fixator has the advantages that: the laboratory rat tail vein injection fixator can be applied to operating platforms of anymedium, is not affected by the height of the operating platform, and is high in adsorption strength of silica gel; and unlike the placement way in which other rat fixators allow rats to get into the barrel, the laboratory rat tail vein injection fixator is opened by means of the turnover cover, the rat is placed into the barrel and the cover can be covered after the rat grabs the fence at the bottom part, and is convenient to grab the rat after the injection is completed.

Description

technical field [0001] The invention relates to the technical field of equipment for supporting or restraining animals, in particular to a tail vein injection fixator for mice. Background technique [0002] Mice are commonly used experimental animals in medical research, and are also commonly used in experiments in medical physiology, pharmacology, pathology, pathophysiology and other disciplines. Mice tail vein injection is an effective method for pharmacology, toxicology, genetics, tumors, immunology and other fields. Injection methods commonly used in the fields of other biological experiments and medical experiments; [0003] Injecting drugs from the tail vein is one of the important administration routes for mice. The tail veins of mice are located on both sides of the tail, one on the left and one on the left. It is very thin and less than 1mm. When injecting, it is necessary to fully expose the tail vein of the mouse and certain injection skills. However, during the ...

Problems solved by technology

[0003] Injecting drugs from the tail vein is one of the important administration routes for mice. The tail veins of mice are located on both sides of the tail, one on the left and one on the left. It is very thin and less than 1mm. When injecting, it is necessary to fully expose the tail vein of the mouse and certain injection skills. However, during the operation, the needle of the syringe is often slipped out or pierced through the tail vein due to the struggle of the mouse. Once it causes subcutaneous bleeding or leakage Edema is more difficult to inject successfully

[0004] The current existing fixer cannot be fixed to the desktop, causing the fixer to roll over or move when the mouse is struggling, resulting in failure of tail vein injection;

[0005] Use a transparent plastic fixer, which is not strong and easy to break, and the fully transparent shell is easy to cause stress in the mouse, and the mouse cannot fix the body inside, and it is easy to curl up or turn over when the tail is pulled The body causes the tail to flip and affect the injection;

[0006] The immobilizer, which presses the neck and waist of the mouse by elastic beading, causes great irritation and discomfort to the animal during the operation, and is likely to cause intense struggle, time-consuming and labor-intensive, and the operator is likely to be bitten
