The peripheral puncture and central venous puncture intubation model serves to help learners systematically master the standardized operation procedures of venous puncture and central venous catheterization. It is a key teaching device in clinical nursing and medical skills training. This model is designed based on the real structure of the human venous system, clearly marking the locations of peripheral veins (such as the back of the hand and forearm) and central veins (such as the internal jugular vein, subclavian vein, and femoral vein), and can simulate puncture and catheter insertion operations at different sites. Through training, trainees can become familiar with the selection of puncture positions, the Angle of needle insertion, the operation steps of guidewires and catheters, and improve the accuracy and safety of establishing intravenous access.

Models are usually made of highly realistic skin and vascular materials, equipped with a liquid injection system and blood return function, which can truly reproduce the touch and visual feedback during puncture, allowing learners to gain an experience close to clinical practice. Some models are also equipped with ultrasonic positioning functions, facilitating operation practice under image guidance. Through repeated training, medical staff can enhance their technical proficiency and emergency response capabilities in a risk-free environment. Overall, this model is an important practical platform for the teaching and assessment of clinical venous access establishment.
