The PICC intervention training model is a simulation teaching aid specially designed for venipuncture and catheter placement training. Its main function is to provide a safe and repeatable operating environment, helping medical students and clinical nurses master the standardized operation procedures of PICC (peripherally inserted central catheter).

This model usually includes a simulation structure of the upper limb venous system, which can truly simulate the course, elasticity and touch of blood vessels, allowing learners to experience puncture resistance and reflux phenomena during operation. By using the model, learners can practice the entire process from vein localization, disinfection, puncture, guide wire introduction, to catheter placement, fixation and rinsing, cultivating hand-eye coordination and operational accuracy.

The model also allows for repeated practice, reducing the risk of operating on real patients and enhancing the efficiency and safety of training. Meanwhile, it holds significant value in nursing teaching, skills assessment and continuing education, and is conducive to enhancing the quality of clinical nursing and patient safety. In conclusion, the PICC intervention training model not only strengthens the integration of theory and practice, but also provides a reliable simulation platform for intravenous catheter operations.
