Multifunctional small animal operating table

Abstract

The invention discloses a multifunctional small animal operating platform, which is a box type rodent holder or a roller type rodent holder. It includes a base and a chassis, a rotating fixed plate located above the base, four claw binding devices located on the rotating fixed plate and a limb fixing cableway located below the claw binding device, a tail fixing device connected to one end of the base, and is arranged on the base and the chassis. The internal pitch angle adjustment mechanism, as well as the rotation angle adjustment mechanism and auxiliary support rotation mechanism that control the rotation angle of the rotating fixed plate. The experimental platform can realize the simple and reliable fixation of experimental mice by only one researcher, and is suitable for mice of various body sizes, and realizes the pitching and rotation adjustment of experimental animals at a fixed angle to meet various experimental positions need. The tail of the rat can be stably fixed, and the blood enrichment and regulation of the tail vein can be realized with one hand, and the four tail veins of the rat can be arbitrarily selected and exchanged.

Description

technical field [0001] The invention belongs to the technical field of animal experiment research equipment, and relates to a multi-functional small animal operating table which is simple and reliable in operation and can meet various research requirements. Background technique [0002] In the current mouse experiments, the researchers first need to fix the mice. At present, the status of the methods and devices for fixing the mice are as follows: [0003] 1. There are two ways to immobilize mice: one is to use a cylindrical container to squeeze and fix the mouse by narrowing the space in the container; the other is to bind the limbs of the mouse with ropes and fix them The rope is tied to the preset point, or connected to the slider through the rope, so that it can slide on the circular cylinder for fixing. However, the above method is relatively complicated to operate, and in most cases, two experimenters are required to cooperate at the same time to complete the immobili...

Problems solved by technology

However, the above method is more complicated to operate, and in most cases, two experimenters are required to cooperate at the same time to complete the immobilization of mice, which not only wastes manpower, but also the immobilization effect is not ideal

[0004] 2. In the method of injecting and taking blood from the tail vein of experimental animals, it is difficult to achieve stable fixation of the tail of experimental animals by using the existing fixation methods, let alone select the tail blood vessels when the trunk of the animal is fixed.

In the current practice, researchers often twist the tail to find the appropriate blood vessel while the animal's trunk is fixed, which is likely to cause tail injury, bruising or necrosis; in addition, due to the need for one hand to hold the Tail, resulting in the restriction of the needle insertion angle of the other hand. Because the tail vein is small, the blood vessel wall is thin and close to the skin, it often punctures the blood vessel and even poses a threat to the health of the operator.

The construction of animal models consumes time, energy and financial resources. If the animal model is damaged due to the mismatch of experimental auxiliary equipment, it will undoubtedly be a huge loss for scientific research.

[0005] 3. Most of the current experimental animal consoles are in the flat-plate fixed mode, that is, the mice are fixed horizontally on the console, and the body position of the mice cannot be adjusted

However, during this operation, it is often difficult to take blood, waste of blood drops, pollution, and animal wounding incidents due to the poor fixed position of the mouse and the unstable fixation.
