The utility model is effective and convenient for the trainee to adjust the inclination and the depth of puncture, and improves the puncture comfort for the patient.

The scheme still has some weak points in the application, because human blood vessel thickness differs, and the condition of expend with heat and contract with cold can appear in addition to external factor influence, simultaneously, because during the venipuncture, receive the influence of nutrition, motion, mood, disease, the condition that the arm blood vessel depth differs also can appear, increases the difficulty of venipuncture. Therefore, the practicability and scene reality of the arm venipuncture training device need to be further improved.
