An indwelling needle with a syringe type vacuum blood collector comprises a catheter assembly and a needle tube assembly. The catheter assembly comprises a catheter (81), a catheter seat (82), an isolation plug (83), an extension pipe (84), a connection seat (85), and a blocking piece. The needle tube assembly is a vacuum blood collector, and comprises a vascular puncture needle tube (11), a blood collection needle tube (12), a blood sample collection pipe (2), and a syringe (3). The vascular puncture needle tube (11) penetrates the isolation plug (83), passes through an inner cavity of the catheter seat (82), and goes through the catheter (81), and a needle tip is exposed out of a pointed end of the catheter. The syringe (3) has a seal cavity (32) and a cylindrical cavity (33) inside, and the seal cavity (32) communicates with the vascular puncture needle tube (11) and the 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. By means of the indwelling needle with the syringe type vacuum blood collector, blood is collected by directly puncturing the needle tube, potential security risks of thrombus and blood return pollution are avoided in addition, the blood collection and the catheter retaining can be done simultaneously only by puncturing a patient once, thereby facilitating the transfusion therapy, reducing pain of the patient, and reducing work load of a medical worker.La présente invention concerne une aiguille à demeure avec un dispositif de prélèvement de sang sous vide de type seringue, qui comprend un ensemble cathéter et un ensemble canule daiguille.
