Abstract

The invention provides a tail vein catheterization system, which belongs to the technical field of medical experimental equipment, and comprises an operation table, a clamping device and an angle adjustment mechanism; a groove is formed on the top of the operation table, and the clamping device is arranged in the groove, and includes a first arc-shaped claw and second arc-shaped claw; one side of the first arc-shaped claw is fixed with a hinge shaft along the axial direction, and both ends of the hinge shaft are rotatably connected to both ends of the groove through bearings; one side of the second arc-shaped claw is hinged with the hinge shaft connection, the arc surfaces of the first arc-shaped claw and the second arc-shaped claw are opposite; the opposite side of the first arc-shaped claw and the second arc-shaped claw is uniformly provided with a plurality of clamping teeth along the length direction for inserting the mouse head and mouse tail limit plate; one end of the first arc-shaped claw and the second arc-shaped claw is provided with a clamping piece for adjusting the opening and closing degree; one end of the operating table is provided with a square groove, and the angle adjustment mechanism is arranged at the bottom of the square groove, which is used for The adjustment clamping device rotates in the groove. The device realizes the fixation of the tail of the mouse, increases the accuracy of drug administration, and also conforms to the spirit of animal ethics.

Description

technical field [0001] The invention relates to the technical field of medical experimental equipment, in particular to a tail vein catheterization system. Background technique [0002] The gene sequence of mice is most similar to the gene sequence of humans, so mice will be involved in the pharmacological experiments, clinical experiments of drugs, and research on the safety, toxicity and potency of biological products, cosmetics, and industrial products. When using mice for experimental research, the product to be studied is usually administered in liquid form through the tail vein of mice. The mouse was immobilized using the immobilizer. [0003] The traditional mouse immobilizer has a simple structure, cannot adjust the volume of the immobilizer according to the size of the mouse, and cannot properly limit all the mice, which makes it impossible to successfully conduct drug administration studies on the tail vein of mice. [0004] Therefore, the present application pro...
