A syringe type vacuum blood collector with a protective needle tip comprises a vascular puncture needle tube (11), a blood collection needle tube (12), a blood sample collection pipe (2), and a syringe (3). A tail end of the vascular puncture needle tube (11) is eccentrically inserted on a puncture needle seat (13) in a manner of closing an outer circumferential surface of the syringe (3). The syringe has a seal cavity (32) and a cylindrical cavity (33) inside. The vascular puncture needle tube (11) communicates with the seal cavity (32), a front end of the blood collection needle tube (12) is fixedly arranged onto a wall of the seal cavity and communicates with the seal cavity (32), and a rear end of the blood collection needle tube (12) and most of the syringe extend backwards and are inserted in a pipe plug of the blood sample collection pipe (2). A tube plug of the vascular puncture needle tube (11), the seal cavity (32), a pipe core of the blood collection needle tube (12), and a pipe cavity of the blood sample collection pipe (2) whose seal cavity is punctured form a blood channel. A sliding groove (36) with a tail end where a back barrier is arranged extends in an axial direction on the side wall of the syringe (3), and a push handle (132) of a puncture needle seat protrudes from the sliding groove (36) and is exposed outside the syringe (3). The puncture needle tube (11), the puncture needle seat (13), the blood collection needle tube (12), and the collection pipe (2) form a sliding member sliding back relative to the syringe (3). With the regression of the sliding member, the puncture needle tube (11) is retracted into an inner cavity of the syringe (3), thereby ensuring that a person is not hurt.La présente invention concerne un dispositif de collecte de sang sous vide de type seringue avec embout protecteur pour aiguille qui comprend une canule daiguille de ponction vasculaire (11), une canule daiguille de collecte de sang (12), un tube de collecte déchan
