Description
Technical Field
The invention relates to the technical field of rat fixing instruments, in particular to a positioning device for positioning the tail of a rat.
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, and pulling the tail by the left hand during injection to ensure that the tail is tightly attached to the middle finger. And there is a fixed apparatus suitable for rat tail intravenous route experiment among the prior art, it restricts the rat afterbody through fixed rat trunk and rocks, however the device can not be fixed the rat trunk completely in the rat tail intravenous route experiment for the rat afterbody still can be swung according to the wrench movement of rat trunk, lead to experimenter to find rat tail vein position before the re-injection accurately, and in the injection process, twist to lead to the rat afterbody to swing thereupon because of the rat buttock, lead to vein blood vessel to break because the rat afterbody swings after making the experimenter prick the vein again. And do not have the device of fixed rat tail among the prior art for the rat tail can only be held between fingers through experimenter's finger, and the tiny messenger of rat tail causes the experimenter to drop from vein at the intravenous route in-process needle point easily, and the experimenter has to look for the vein again and injects, and the rat tail leaves the wound easily.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides a positioning device for positioning the tail of a rat, and aims to solve the problem that the tail of the rat in the prior art cannot be stably fixed, so that the tail intravenous injection experiment of the rat fails.
In order to achieve the purpose, the invention provides a positioning device for positioning the tail of a rat, which comprises a fixing plate for placing the body of the rat, wherein one end of the fixing plate is connected with a positioning block, a positioning groove for fixing the tail of the rat is formed in the end face of the positioning block, the positioning groove is formed in the length direction of the positioning block, one end of the positioning groove extends to the edge of the end face of the positioning block and is provided with an inlet for the tail of the rat to penetrate into the positioning groove, a limiting part for limiting the root swing of the tail of the rat is arranged on the fixing plate, a positioning part for clamping the tail of the rat so that the tail of the rat cannot swing is arranged in the positioning groove, a binding part for limiting the body of the rat to swing is further.
The technical scheme is adopted, and the method has the advantages that: an experimenter puts a rat on a fixing plate horizontally, plugs the head of the rat into a fixing cover, fixes the body of the rat on the fixing plate through a binding piece so that the rat can be preliminarily fixed on the fixing plate, then places the tail of the rat on a positioning groove through an inlet, at the moment, preliminarily fixes the tail of the rat on the positioning groove, clamps the tail of the rat through the positioning piece so that the tail of the rat cannot swing on the positioning groove, at the moment, the tail of the rat cannot swing, then fixes the root of the tail of the rat through a limiting piece, the root of the tail of the rat is connected with the hip of the rat, the limiting piece further limits the swing of the tail of the rat, the swing of the tail of the rat can influence the twisting of the root of the tail of the rat, the root of the tail of the rat is limited through the limiting piece, so that the acting force caused by the twisting of the root of the tail of the rat is reduced to the, when the tail of the rat is completely fixed, the experimenter can start intravenous injection; the tail of the rat cannot be affected by acting force caused by twisting of the body of the rat or twisting of the hip of the rat due to the arrangement of the technology, the tail of the rat cannot swing in the injection process, the rat cannot even vibrate along with the body of the rat, the success rate of intravenous injection is further increased, the intravenous injection of experimenters can be ensured to be successful at one time, the injection efficiency of intravenous injection experiments is further accelerated, the breakage of vein vessels of the tail of the rat is avoided, meanwhile, the phenomenon that a large number of wounds appear on the surface of the rat due to intravenous injection of the tail of the rat is avoided, the device is suitable for being used by new hands of experiments, the new hands of experiments can be successful for the first time, and the proficiency of intravenous injection is master; the setting of fixed cover ensures that the rat head can not lead to the rat head to rock because of neural reaction when injecting, and the setting of binding piece is tentatively fixed the rat afterbody, and further assurance rat tail can not receive the influence.
