Embodiment Construction

[0037] Embodiments of the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solutions of the present invention more clearly, and therefore are only examples, rather than limiting the protection scope of the present invention.

[0038] see Figure 1 to Figure 4 , the present invention provides a subcutaneous injection fixing device for experimental mice, comprising a fixing seat 10, a limb fixing mechanism 20 and a trunk fixing mechanism 30, the mouse is placed on the fixing seat 10, its limbs are fixed by the limb fixing mechanism 20, and the trunk is fixed The mechanism 30 fixes the body, thereby preventing the mouse from scratching the experimenter or struggling to affect the experimental effect during the injection.

[0039] Specifically, such as figure 1 and figure 2 As shown, the limb fixing mechanism 20 includes four fixing rubb...

Abstract

The invention discloses a laboratory mouse subcutaneous injection fixing device. The laboratory mouse subcutaneous injection fixing device comprises: a fixing base internally provided with a cavity; a four-limb fixing mechanism which comprises four fixing rubber bands, wherein the fixing rubber bands are arranged on the fixing base and correspond to the positions of the four limbs of the mouse; and a trunk fixing mechanism which comprises a fixing sleeve, wherein a through hole communicated with the cavity is formed in the fixing base, a baffle which is in sliding connection with the cavity and can open and close the through hole is arranged at the top of the cavity, one end of the fixing sleeve is hinged to the surface of the fixing base, the other end of the fixing sleeve can be inserted into the through hole, a plurality of elastic limiting plates are arranged on the inner side face, away from the hinged end, of the fixing sleeve in the axial direction, and the limiting plates are arranged in the direction of the hinged end. By using the fixing device for the subcutaneous injection of the laboratory mouse, the limbs and the trunk of the mouse can be fixed, so that the mouse can be prevented from scratching an experimenter and struggling the body to influence the experiment effect during a subcutaneous injection experiment.

Description

technical field [0001] The invention specifically relates to a subcutaneous injection fixing device for experimental mice. Background technique [0002] Experimental mice refer to white fur rats or mice that are widely used as experimental animals in the teaching and research of physiology, medicine, pharmacy and other disciplines. In medical research, different experimental purposes can be achieved by subcutaneous injection of mice. It has important medical value and scientific research significance. [0003] For subcutaneous injection of mice, the neck or lateral thigh of the mouse is generally selected, and the skin of the mouse is pinched for injection. In the prior art, in order to ensure the safety of the experimenter, the limbs of the mouse are usually fixed by a fixing device, so as to prevent the mouse from scratching the experimenter. However, because the subcutaneous injection needs to be uniform and slow, during the continuous injection process, if the body of ...
