The full-function central venous puncture and injection trunk model is a highly realistic clinical nursing and medical skills training device, mainly used by medical students and nursing staff to repeatedly practice and master key techniques such as central venous puncture, catheter insertion and intravenous infusion in a risk-free environment.

This model is usually designed in proportion to the adult trunk, with a surface made of soft skin material, providing a realistic touch. The anatomical landmarks of the collarbone, neck and subclavian vein can be clearly felt, helping trainees accurately locate. The internal vascular system is reasonably designed, enabling puncture of the internal jugular vein, subclavian vein and femoral vein, and it also has the function of blood return.

Make the operation more clinically authentic. During the usage, trainees can not only train the puncture Angle, depth and technique, but also complete the entire process including guide wire insertion, dilation and catheter fixation. This model features strong durability, the ability to be punctured and operated multiple times, effectively enhancing trainees' practical skills and clinical thinking.

Through repeated practice, the error rate in actual operation can be reduced, the quality of nursing and patient safety can be improved, and it is an indispensable important teaching tool in clinical training and assessment in medical colleges and hospitals.
