Description

Technical Field

[0001] The utility model relates to the technical field of mouse fixation, in particular to an adjustable mouse fixer for experiments. Background Art

[0002] Mice are commonly used experimental animals. When conducting drug tests, injections are required, generally including subcutaneous administration, intradermal administration, intramuscular injection, tail vein injection, etc. Mice in a struggling state are not convenient for injection, so they need to be fixed. Therefore, some technical solutions for fixing mice have also appeared in the prior art. For example, a fixing device for improving the safety and efficiency of mouse injection is recorded in announcement No. CN220275765U, which includes a barrel and a buckle cover, the buckle cover is buckled on the top of the barrel, and the side of the barrel is provided with an injection fixing port, and the injection fixing port is a semi-closed opening, so that the tail of the mouse can be extended after the mouse is placed in the barrel;

[0003] When the above device is used, the injection site of the mouse can be easily raised and fixed on the outer wall of the cylinder under the premise of effectively preventing the mouse from biting. After the mouse is fixed, it can be stably fixed with one hand, reducing accidental injuries to the experimenter and the mouse during the injection operation due to poor fixation. The device is also suitable for other tailed animals. However, when the tail is fixed, the mouse stays in the outside world and adapts to the external environment. When the cylinder is made of transparent material, the mouse will struggle when the experimenter touches it, and it is not convenient to put it into the device. When it is made of opaque material, the inside of the cylinder is relatively dark. The dark environment will provide the mouse with a sense of security, which is convenient for the mouse to actively drill into the device, but it will block the experimenter's line of sight, making it inconvenient to observe the fixed state of the mouse.
