Description

technical field [0001] The invention relates to the field of medical experiment equipment, in particular to a continuously adjustable tail vein injection auxiliary fixation device for mice. Background technique [0002] Tail vein injection of mice (including white mice, C57BL / 6 black mice, etc.) is a common and necessary operation in the field of basic biomedical research. However, because the tail veins of mice are extremely thin, and some species of mice are extremely active and resist violently during the injection process, the experimental operation of mouse tail vein injection is quite difficult and the success rate is low. In the absence of auxiliary equipment, the experimenter must complete the learning curve practice of 100-200 injections to achieve a success rate of more than 80-90%. Contents of the invention [0003] The present invention aims to provide an auxiliary mouse immobilization device that can adapt to mice of different sizes and is convenient for medi...
