The structure of a pen-type blood collection needle is a through needle tube with sharp cutting edges at both ends. The middle and lower part of the needle tube is fixed on the needle holder. The front end is called a vein puncture needle, and the back end is called a blood collection needle. Clinically, blood collection is usually used together with needle holders and disposable vessel collection. When using, the blood collection needle is rotated and fixed at the front end of the external tube of the needle holder, and venipuncture is carried out. After a successful operation, the vacuum collection vessel is inserted into the posterior cavity of the needle holder, so that the cutting edge of the posterior end of the blood collection needle passes through the blood blocking sleeve and punctures into the vacuum tube rubber plug, and the blood is pumped into the blood collection tube under the action of negative pressure. This repetition can realize the collection of multi-tube blood specimens.
