The invention discloses a fixing device for rat tail intravenous injection. The fixing device comprises a containing plate, a distance measuring plate protrudes out of the side wall of one end of thecontaining plate, two fixing assemblies are arranged on the distance measuring plate in a sliding mode, each fixing assembly comprises a sliding plate and two vertical plates, the sliding plates are arranged on the distance measuring plate in a sliding mode, the two vertical plates are vertically arranged on the two sides of the sliding plate and attached to the two side walls of the sliding plate, a rolling groove is formed in the end surface of the sliding plate, a first pin roller is arranged on the rolling groove in a rolling mode, the first pin roller is perpendicular to the vertical plates, sliding holes are formed in the vertical plates, a second pin roller is arranged on the sliding plate, sliding blocks protrude out of the two ends of the second pin roller respectively, the sliding blocks slide in the sliding holes in the length direction of the sliding holes so that the second pin roller can move up and down above the first pin roller, a sliding piece and a driving piece arearranged on the sliding plate, and a binding piece is arranged on the containing plate. The fixing device solves the problem that in the prior art, the tail of a rat is not stably fixed, so that an experimenter cannot accurately perform intravenous injection on the tail of the rat.
Description
technical field [0001] The invention relates to the technical field of rat fixing devices, in particular to a fixing device for tail vein injection of rats. Background technique [0002] In animal experiments in the prior art, rat tail vein injection is undoubtedly a common experimental method, and usually the first few steps are particularly important in rat tail vein injection. The first step is to fix the rat first. Straighten the tail and taut it. When performing tail vein injection, a special fixing device can be used for fixing, such as a tail vein injection stand or a thick mineral water bottle; in the second step, the operator wipes the tail with an alcohol cotton ball to dilate the blood vessels; in the third step, use Fix the tail of the rat with the middle finger and ring finger of the left hand. When injecting, pull the tail with the left hand so that the tail is close to the middle finger. The place where the middle finger is raised is the needle insertion site...
