Laboratory rat fixing device

Abstract

The invention relates to a laboratory rat fixing device, so as to solve the problem of lack of a safe, effective, fast and convenient fixing mode in the existing laboratory rat injection process. Thelaboratory rat fixing device includes a laboratory table, on which various rotating ring groups are vertically arranged in the axial direction. The rotating ring group is formed by sequentially nesting and rotatably connecting at least two eccentric rings with different sizes. The upper end faces of the at least two eccentric rings are respectively flush with the upper end face of the laboratory table. The eccentric ring at the innermost layer of the rotating ring group is provided with a rotary table which is coaxially and rotatably connected with the inner annular surface of the eccentric ring. The rotary table is provided with two slot holes vertically penetrating the rotary table. The device of the invention also includes multiple cable ties in one-to-one correspondence with the rotating ring groups and multiple counterweight blocks which are arranged below the rotating ring groups and are in one-to-one correspondence with the cable ties. Two ends of the cable tie respectively penetrate through the two slot holes from top to bottom and are arranged below the rotating ring group and connected with the counterweight block. Brake discs which are arranged below the rotating ring groups and are in one-to-one correspondence with the rotating ring groups are arranged on the laboratory table. The brake discs are driven through a driving mechanism to move vertically on the laboratory table.

Description

technical field [0001] The invention relates to a fixing device for experimental mice, in particular to a fixing device for experimental mice. Background technique [0002] Experimental mice are the main subjects of in vivo experimental research. Before clinical observation, the experimental drugs need to be injected into the experimental mice. However, the experimental mice are small and usually use tail puncture injections, so it is necessary to The injection can only be effectively carried out after the limbs and tail are fixed; at present, in the process of this type of injection, manual capture or binding is mostly used, and the experimental rat is a rodent, which can easily cause the staff to be bitten. Moreover, Whether it is catching or binding, it is difficult to grasp the strength of grasping and binding, and it is easy to cause damage to the limbs of experimental mice. Contents of the invention [0003] In view of the above situation, in order to make up for th...
