The central venous puncture and intubation model is a medical teaching device used to train the operation of central venous catheterization. It is made in the proportion of a real person's neck and chest, accurately reproducing the anatomical positions and surface marks of commonly used puncture sites such as the internal jugular vein and subclavian vein. The model usually adopts highly realistic skin materials and internal puncture vascular pipelines, and has the function of drawing back simulated blood, enabling trainees to obtain feedback close to clinical reality during operation.

Functional features

The anatomical structure is precise, about the size of a real person, and has obvious surface landmarks, including: the supraclavicular notch, the sternocleidomastoid muscle, the clavicle, and the right rib.

2. Realistic vascular structures, mainly including: internal jugular vein and subclavian vein, etc.

3. Deep vein intubation: subclavian vein puncture, internal jugular vein puncture and elbow crease vein puncture.

4. Intubation practice of the Swan-Ganz catheter can be performed.

5. The skin and veins can be replaced, and there will be a distinct sense of emptiness when inserting the needle.

Through this model, learners can repeatedly practice steps such as needle insertion, guide wire placement, dilation and catheter fixation, and become familiar with aseptic operation procedures as well as the correct needle insertion Angle and depth. Its advantages lie in  safe operation and repeatable training , avoiding the risk of directly practicing on patients, while helping trainees build their sense of touch and spatial positioning ability.

This model is widely applied in intensive care medicine, anesthesiology, surgery and nursing training, and is suitable for the skill improvement of doctors, nurses and medical students. It is an important training platform for effectively connecting theoretical knowledge with clinical practice.
