The arm venipuncture model is a teaching tool commonly used in nursing and medical skills training. It is mainly used to simulate the structure of the upper limb venous system in the human body, helping trainees master basic operation skills such as venipuncture, infusion, and blood collection proficiently. This model is usually composed of simulated skin, venous pipelines and a system that can inject simulated blood, which can truly reproduce the touch of veins and the phenomenon of blood return, making the training closer to clinical reality.

Through repeated practice, trainees can master key skills such as the selection of puncture sites, the control of needle angles, the fixation of needles and the prevention of leakage, become familiar with aseptic operation norms, and improve the accuracy and safety of operations. The model can also be used for teaching assessment and skills evaluation, helping teachers conduct standardized training.

The application of the arm venipuncture model not only enhances students' practical skills and self-confidence, but also reduces the risks brought by practicing on real patients, providing a safe, scientific and effective training platform for clinical nursing and emergency operations.
