What is the use of venous blood needles?

Posted by Admin | 07 Jan
There are three main methods of using venous blood collection needles:



1. Needle stop at sight of blood return
2. After seeing the blood return, enter a little needle stop
3. Flexible control according to individual venous conditions (the thick, straight, superficial, and flexible blood vessels will stop the needle after a small amount of blood is returned; for small blood vessels or deep blood vessels that are difficult to grasp, the needle will be stopped when the blood is returned)
