The central venous puncture and intubation model is mainly used for teaching, training and assessment of medical staff in the related skills of central venous catheterization (CVC), and it is an important tool for clinical practice. Its functions are reflected in the following aspects:

Firstly, it helps learners become familiar with the anatomical locations of the central veins, such as the surface markers of the internal jugular vein, subclavian vein and femoral vein regions, which facilitates their mastery of the puncture direction and positioning techniques.

Secondly, the model can simulate the resistance changes of the skin and blood vessel walls, allowing trainees to gain a nearly realistic tactile experience throughout the entire process, including needle insertion, blood return judgment, guide wire placement, and the insertion of expanders and catheters.

Secondly, through repeated practice, learners can correct incorrect movements in a risk-free environment, enhance the standardization of operations, and reduce clinical complications such as accidental arterial puncture, pneumothorax or infection.

Finally, this model is applicable to teaching in colleges and universities, standardized training for resident physicians, nursing skills assessment, and emergency operation drills within hospitals, improving the overall safety and success rate of central venous catheterization operations.
