Description

Technical Field

[0001] The utility model relates to the technical field of mouse tail vein injection auxiliary equipment, in particular to a multi-body-size and multi-angle tail vein injection auxiliary device for mice. Background Art

[0002] When the experimenter performs a tail vein injection on the mouse, the mouse body needs to be fixed before the tail vein injection is performed. The fixed part of the existing mouse tail vein injection auxiliary device is mostly an integrated cylinder [patent number CN202320661123.4]. During the experiment, because the inner diameter of the cylinder that accommodates the mouse remains unchanged and the body sizes of the mice vary greatly, large mice will find it difficult to enter the auxiliary device, and small mice will move around in the cylinder and be difficult to fix. The existing mouse tail vein injection auxiliary fixing device can only fix the tail vein at a specific angle [patent number CN202222324968.2], and the direction is single and cannot adjust the angle according to the habits of different operators. For this reason, a multi-angle tail vein injection auxiliary device for mice of different body sizes is specially proposed. Utility Model Content
