[0002] A blood collection needle is an instrument used to collect blood samples during medical examinations. Blood collection needles are divided into three categories: split blood collection needles, pen-type blood collection needles and arterial blood collection needles. The pen-type blood collection needle has a through needle tube with sharp cutting edges at both ends. The middle and lower sections of the needle tube are fixed on the needle holder. The front end is called a venous puncture needle, and the rear end is called a blood collecting needle.
