A vacuum blood collector used outside a human body for clinical care, and in particular, a vacuum blood collector with an indwelling catheter. The vacuum blood collector with the indwelling catheter is characterized in that a syringe (43) is rigidly connected to a vascular access needle tube (31), a blood collection needle tube (51), and a blood sample collection pipe (2), so that the vascular access needle tube (31), the blood collection needle tube (51), and the blood sample collection pipe (2) are not only integrated into a whole but also are combined to form a traditional syringe structure. The advantages are as follows: the structure is simplified, the control operation is convenient, and the operation process is very similar to a traditional syringe operation, and the work load and psychological burden of a medical worker are reduced to the greatest extent; and even in the case that the limbs motion range is large when the medical worker meets with unconscious, restless, uncooperative patients and infant patients, misoperations are unlikely to occur, thereby improving the safety and success degree of operations. A puncture needle is replaced by the indwelling catheter, thereby preventing the phenomenon that a vessel is harmed by the puncture needle, and reducing the occurrence of phlebitis and metal allergy reaction. |
