Snsek-MS-100 Tail Vein Injection Visualizer

Brand: Penncentury SNSEK

Model: Snsek-MS-100

Intravenous injection into the mouse tail is a challenging task that requires skill, practice, and patience. During experiments, multiple failed attempts can lead to frustration. It is widely agreed that there are no shortcuts to mastering tail vein injection. The key to success lies in repeated practice, honing the technique, and gaining confidence. However, even with confidence, it is still difficult to achieve complete certainty. The challenges mainly arise from three factors: 1) the firmness of the animal's restraint, 2) the fullness of the tail veins, and 3) the direction of the needle when entering the vein.

The Tail Vein Injection Imaging Device we developed solves this problem: First, using a mouse tube, the mouse can be loaded quickly, firmly secured, and the mouse is in a comfortable position without jumping forward, ensuring stability during injection; second, using light to illuminate the mouse's tail to make the blood vessels in the tail visible, so that the needle tip can be inserted in a targeted manner under visible conditions, rather than blindly relying solely on the feel of the hand. You can tell whether the needle has entered the blood vessel by swinging the needle to see if the blood vessel moves with it. You no longer have to pursue the feeling of the needle missing when entering the blood vessel (in fact, this kind of feel is generally difficult to experience in a short period of time).
