During the advancing process of the outer steel pipe of the phlebotomist, when necessary, the inner steel pipe can be pushed into the inner steel pipe to inject anesthetics. When the flare of the outer steel pipe reaches the predetermined position, the vein needs to be cut off at this position, and then the vein is drawn out. This device has a large trauma. It is not very convenient to use, and this kind of phlebotomy is made of impermeable steel material, the lumen is not easy to clean, and the production cost is also high
