The invention discloses an intelligent training method and system for central venipuncture. The method comprises the steps of case selection, simulation of article preparation, pre-operation preparation simulation, simulated disinfection, simulation of local anesthesia, simulation of puncture catheterization, simulation of fixation and simulation of postoperative treatment. When simulation of puncture catheterization is carried out, the puncture position of the simulated puncture is detected, the puncture angle of a simulated puncture needle is detected, the puncture depth of the simulated puncture is detected, whether the puncture process is correct or not is judged, a guide wire or simulated guide wire placement depth is detected, the guide wire or simulated guide wire placement speed isdetected, the catheter or simulated catheter placement depth is detected, whether the guide wire and catheter placement process is correct or not is judged according to the detection result, and feedback is recorded; according to the intelligent training method and system for central venipuncture, an operator is guided to carry out simulated central venipuncture operation through prompt and timely feedback, the operation process is detected, timely given, judged and judged, the result is timely fed back to the operator, and the operator is guided to carry out operation.
