For intravenous injection, the common solution is to use special light to visualize the vein. Under this light, the venous blood will appear black and stand out. This solution is clinically applied. It is more common and is less used in animal experiments on mice, but there are still some shortcomings, such as only for mice (17-40g), and the equipment is cumbersome, and often lack of attention to the angle and position of the needle, because the veins of mice Generally very thin and thin, if you do not pay attention to the angle of needle insertion, even if you see the blood vessel, there is a high probability of piercing the blood vessel;

There are many ways to collect blood from rats, such as cardiac puncture, which has a high fatality rate, and decapitation of rats, which can only be collected once, and cannot be used for long-term dynamic detection of blood indicators. Complicated, and tail vein blood collection and tail-done blood collection are relatively simple, but there are many difficulties.
