The significance of the arm venipuncture training model lies in providing a safe, standardized and repeatable operation training platform for nursing and clinical teaching. The model highly simulates the anatomical structure and vein course of the human arm, and can truly simulate blood return, resistance and puncture feel, helping learners accurately master the needle insertion Angle, depth and fixation method. Through repeated practice, the success rate of venipuncture can be effectively improved, and the pain and injury caused to patients due to unskilled operation can be reduced.

This model can also be used to standardize aseptic operation procedures, maintain intravenous access and train for complication identification, enhancing trainees' risk awareness and emergency response capabilities. The arm venipuncture training model is of great significance in reducing the risks of clinical teaching, improving the level of nursing skills and ensuring patient safety. It is an important tool in nursing teaching and skills assessment.
