A mouse tail vein injection aid device

Abstract

This utility model relates to the field of mouse tail vein injection technology, and discloses an auxiliary device for mouse tail vein injection, including a restraint cylinder. Two locking tabs are fixedly connected to the lower end of the restraint cylinder on both sides. A base is provided at the lower end of the restraint cylinder, and a placement pad is fixedly connected to the upper end of the base. Locking grooves are formed on both sides of the upper end of the placement pad. The outer surfaces of the two locking tabs respectively engage with the interiors of the two locking grooves. Suction cups are fixedly connected to the lower circumference of the base, and a positioning mechanism is provided at the lower end of the base. This utility model allows the device to be firmly fixed to the experimental table during injection operations, effectively preventing displacement due to mouse movement, making the device more stable during use, and further improving the ease of use.
