The arm venipuncture training model is a simulation teaching aid used for basic nursing and clinical skills teaching, and it has significant teaching and practical training value.

Firstly, this model is designed based on the real arm proportions, with a realistic skin texture and vein distribution. It can clearly touch the "blood vessels", helping trainees master the skill of finding veins.

Secondly, the model can undergo repeated puncture training. After the needle enters the blood vessel, it can simulate the phenomenon of blood return, allowing learners to experience a feel similar to real operation in a safe environment.

Thirdly, it supports various venous operation training, such as infusion, blood drawing and indwelling needle puncture, etc., meeting the teaching needs of different levels. Meanwhile, the material of this model is durable and can withstand multiple punctures without being easily damaged, making it convenient for long-term use.

By using this model, trainees can repeatedly practice under risk-free conditions, correct incorrect movements, and gradually build operational confidence. Overall, the arm venipuncture training model not only enhances the practical skills of nursing and medical students, but also effectively ensures the safety and comfort of clinical patients.
