The venipuncture and infusion arm model is a simulation training tool often used in medical and nursing teaching, mainly to help trainees master the basic skills of venipuncture and infusion operations.

This model is made in accordance with the real proportion and appearance of a human arm. Its skin is soft and elastic, and it is equipped with simulated blood vessels inside, which can simulate the feeling of needle injection and the phenomenon of blood return, allowing trainees to have an experience close to clinical practice. During the teaching and training process, trainees can repeatedly practice operations such as venipuncture, connection and fixation of infusion pipes, and infusion of medicinal liquids, gradually improving their technical proficiency and operational standardization.

Meanwhile, this model effectively reduces the risks associated with direct practice on patients, ensuring their safety and comfort. It is not only suitable for the basic skills training of nursing staff and medical students, but also can be used as an assessment tool to evaluate the operational proficiency of trainees.

Overall, the venipuncture infusion arm model plays a significant role in enhancing clinical skills, standardizing nursing operations, and ensuring medical safety.
