Abstract

The invention provides a caudal vein catheterization system, and belongs to the technical field of medical experiment equipment. The caudal vein catheterization system comprises an operation table, aclamping device and an angle adjusting mechanism; a groove is formed in the top of the operation table, and the clamping device is arranged in the groove and comprises a first arc-shaped claw and a second arc-shaped claw; a hinge shaft is fixedly arranged on one side of the first arc-shaped claw in the axial direction, and two ends of the hinge shaft are respectively and rotationally connected with two ends of the groove through bearings; one side of the second arc-shaped claw is hinged to the hinge shaft, and the arc surfaces of the first arc-shaped claw and the second arc-shaped claw are opposite to each other; a plurality of clamping teeth are evenly arranged on the opposite sides of the first arc-shaped claw and the second arc-shaped claw in the length direction and are used for inserting a mouse head limiting plate and a mouse tail limiting plate; one end of each of the first arc-shaped claw and the second arc-shaped claw is provided with a clamping piece for adjusting the openingdegree; and a square groove is formed in one end of the operation table, and the angle adjusting mechanism is arranged at the bottom of the square groove and is used for adjusting the clamping deviceto rotate in the groove. According to the caudal vein catheterization system, the tail of a mouse is fixed, dosing accuracy is improved, and meanwhile, the caudal vein catheterization system conformsto the animal ethics spirit.

Description

technical field [0001] The invention relates to the technical field of medical experiment equipment, in particular to a tail vein catheterization system. Background technique [0002] The genetic sequence of mice is the closest to that of humans, so mice will be involved in the pharmacological experiments of drugs, clinical experiments, and research on the safety, toxicity, and potency of biological products, cosmetics, and industrial products. When using mice for experimental research, usually the product to be studied is administered through the tail vein of the mouse in the form of liquid. The mouse was immobilized using a holder. [0003] The traditional mouse holder has a simple structure, and the volume of the holder cannot be adjusted according to the size of the mouse, and it is impossible to better limit all the mice, which leads to the inability to successfully carry out drug administration research on the tail vein of the mice. [0004] Therefore, the present ap...
