A syringe type vacuum blood collector comprises a syringe (3) and a blood sample collection pipe (2). The syringe (3) has a seal cavity (32) and a cylindrical cavity (33) inside, and the seal cavity (32) communicates with a vascular puncture needle tube (11) and a blood collection needle tube (12), so as to be used as a blood return cavity to help a user observe the blood return. The blood sample collection pipe (2) is sleeved in the cylindrical cavity (33). By pushing the blood sample collection pipe (2) forward relative to the syringe (3), the blood collection needle tube (12) punctures a seal layer (21) formed by a rear end wall of a pipe plug of the blood sample collection pipe (2), so as to collect blood. The blood collector makes the vascular puncture needle tube (11), the blood collection needle tube (12), and the blood sample collection pipe (2) integrated into a whole and combined to form a traditional syringe structure, thereby simplifying the structure and facilitating the control operation. The operation process of the blood collector is very similar to a traditional syringe operation, and can reduce the work load and psychological burden of a medical worker and even in the case that the limbs motion range of a patient is large, misoperations are unlikely to occur, thereby improving the safety and success degree of operations. The blood collection needle further comprises a safe structure therefore, it is ensured that a regressed puncture needle tube is not pushed out to hurt a person, and that the blood collector is not used again.La présente invention concerne un dispositif de prélèvement de sang sous vide de type seringue qui comprend une seringue (3) et un tube de prélèvement de sang (2).
