The arterial puncture arm model is a highly realistic teaching aid specially designed for clinical nursing and medical student skills training, and it plays an important teaching role.

Firstly, this model highly restores the anatomical structure of the arm and the distribution of arteries, enabling trainees to directly understand the puncture site, the Angle of needle insertion and the direction of blood vessels, and helping them master the key points of operation.

Secondly, the model can simulate arterial pulsation and blood return phenomena, allowing trainees to practice puncture techniques in a safe environment, experience the feel and feedback of real operation, and thereby improve the accuracy of operation.

Thirdly, it supports repeated training multiple times, which is convenient for correcting incorrect operations, cultivating trainees' proficiency and confidence, and at the same time avoiding the risks that may arise from directly practicing on patients.

In addition, the arterial puncture arm model can also be used for assessment and skills evaluation, helping teachers objectively evaluate the mastery of trainees. Overall, this model has played a significant role in improving clinical arterial puncture techniques, ensuring patient safety and the quality of medical education.
