Description
Technical Field
The invention relates to the technical field of rat fixing instruments, in particular to a fixing device for rat tail intravenous injection.
Background
In the animal experiments in the prior art, tail intravenous injection of rats is undoubtedly a common experimental means, and in the tail intravenous injection of rats, the first steps are particularly important, wherein the rats are fixed firstly, and the tails are straightened and tightened. When tail vein injection is carried out, special fixing devices can be used for fixing, such as a tail vein injection frame or a thick mineral water bottle; secondly, an operator wipes the tail with an alcohol cotton ball to expand the blood vessel; and thirdly, fixing the tail of the rat by using the middle finger and the ring finger of the left hand, pulling the tail by the left hand during injection to ensure that the tail is tightly attached to the middle finger, wherein the high part of the middle finger pad is the needle insertion part, and the needle insertion part is generally selected to be 2/3 away from the tail tip, so that the skin is thinner, the blood vessel is clear, and the needle insertion is easy. When the needle is inserted, the needle head is parallel to the table surface, the needle point is slightly downward, once the needle enters, the needle head needs to be slightly lifted upwards to enter, the needle head enters along the blood vessel, and the needle head can be observed to advance by naked eyes. If the needle head advances in the blood vessel, the needle can be obviously felt to be unobstructed and has no resistance. The above-mentioned be experimental method, but among the prior art, can be less with the fixed apparatus of rat, generally fix rat trunk, then operating personnel fixes rat afterbody through middle finger and ring finger of left hand, however the rat still can wrench movement in the experiment its trunk, lead to the afterbody also can wrench movement along with trunk wrench movement, make experimenter's syringe needle can not insert the mouse afterbody, and the mouse afterbody is thinner, it is easy to make mouse afterbody appear the wound when the syringe needle is inserted by mistake, make the mouse afterbody impaired, and the mouse afterbody receives acupuncture stimulation to produce neural reaction easily and lead to the tail to rock, make experimenter can not continue intravenous route, further increase experimenter's experimental duration.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides a fixing device for rat tail intravenous injection, which aims to solve the problem that experimenters cannot accurately carry out intravenous injection on the tail of a rat due to unstable fixation of the tail of the rat in the prior art.
In order to achieve the above purpose, the invention provides a fixing device for tail intravenous injection of a rat, which comprises a containing plate for containing the body of the rat, wherein a distance measuring plate protrudes from the side wall of one end of the containing plate, two fixing components for fixing the tail of the rat are arranged on the distance measuring plate in a sliding manner, each fixing component comprises a sliding plate and two vertical plates which are parallel to each other, the sliding plate is arranged on the distance measuring plate in a sliding manner, the two vertical plates are vertically arranged on the two sides of the sliding plate and are attached to the two side walls of the sliding plate, a rolling groove is formed in the end face of the sliding plate, a first roller is arranged on the rolling groove in a rolling manner, the first roller and the vertical plates are arranged perpendicular to each other, a sliding hole is formed in each vertical plate, a second roller is arranged on the sliding plate corresponding to the first roller, sliding blocks protrude from the two ends of the second roller and are inserted into the sliding holes respectively, and the sliding blocks slide in the sliding holes along the length direction of the The sliding plate is provided with a sliding piece for driving the sliding block to slide in the sliding hole and a driving piece for driving the second roller to press the first roller, and the accommodating plate is provided with a binding piece for fixing the body of the rat.
