The purpose of the central venous puncture and intubation model is to provide a safe, intuitive and repeatable training platform for medical learners and clinical personnel. Central venous puncture and intubation is a common and high-risk operation in clinical practice, mainly used for intravenous infusion, hemodynamic monitoring and drug treatment. If the initial training is directly conducted on patients, it is easy to cause injuries and complications. Therefore, the application of the model is particularly important.

Through this model, trainees can master the basic principles and operational steps of venipuncture in a risk-free environment, including the recognition of body surface markers, the selection and Angle control of the puncture needle, the correct insertion of guide wires and catheters, as well as the fixation and care after puncture. Models are usually designed with realistic anatomical structures, such as the internal jugular vein, subclavian vein and other puncture channels, enabling trainees to become familiar with the characteristics of different puncture sites in practice.
