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...

Embodiment

[0032] tail vein catheterization system, such as Figure 1-4 As shown, it includes an operating table 1, a clamping device and an angle adjustment mechanism; a groove 2 is provided on the top of the operating table 1, and the clamping device is arranged in the groove 2;

[0033] The clamping device includes a first arc-shaped claw 3 and a second arc-shaped claw 4, such as image 3 One side of the first arc-shaped claw 3 is fixedly provided with a hinge shaft 22 along the axial direction, and both ends of the hinge shaft 22 are rotatably connected to both ends of the groove 2 through bearings; one side of the second arc-shaped claw 4 is connected to the hinge shaft 22. Hinged connection, the arc surfaces of the first arc-shaped claw 3 and the second arc-shaped claw 4 are opposite; the opposite side of the first arc-shaped claw 3 and the second arc-shaped claw 4 is uniformly provided with a plurality of clamping teeth 5 along the length direction; A rat head limiting net 7 and ...
