The main purpose of the venous intervention training model is to help learners master the basic principles and standard procedures of venous intervention operations. It is an important teaching tool in clinical nursing, interventional medicine and anesthesia training. This model is designed based on the structure of the human venous system, accurately reproducing the direction and distribution of peripheral and central veins. It can be used for a series of operation training such as puncture, guide wire insertion, catheter placement, fixation and catheter flushing. Through model practice, trainees can become familiar with the key steps of establishing interventional pathways, master aseptic techniques and the correct puncture angles, and improve the accuracy and safety of clinical operations.

Models are usually made of highly realistic materials, featuring a blood return system and a realistic touch feel. They can simulate the skin elasticity and vascular response during puncture, making the learning experience closer to clinical practice. Some models are also equipped with image guidance functions for ultrasonic positioning and guidance practice. Through repeated training, learners can continuously improve their technical proficiency and emergency response capabilities in a safe and controllable environment. Overall, the venous intervention training model is of great significance in cultivating professional skills, improving the quality of care and ensuring patient safety.
