Which is better to inject with a blunt needle or a sharp needle?

In fact, this problem, in the evolution of thousands of years, there are only a few large blood vessels in the human face, which are less dangerous. Even if a small amount of foreign bodies is injected into most blood vessels, there is no big problem. A lot of people debate whether it is better to use a blunt needle or a sharp needle. Both have advantages. The blunt needle has a low probability of puncturing the blood vessel and is evenly spread: the sharp needle is flexible and precise.

However, in order to pursue safety, most people choose blunt needles, but they must remember that blunt needles will puncture blood vessels, and they cannot grasp the anatomical level. more dangerous. However, in the context of emphasizing blunt needles, everyone forgets that it is fatal to be familiar with the anatomy of the face and the distribution of blood vessels. As long as the anatomical structure is mastered, both blunt and sharp needles are safe.

Therefore, whether a blunt needle or a sharp needle is used, it must be based on a regular hospital and a professional doctor to better solve the problem.
