Arm venipuncture model - multifunctional intravenous infusion arm model

 This multi-functional intravenous infusion arm model (arm venipuncture model) simulates the distribution of the main venous vascular system of the human arm, which can be used to simulate venipuncture and injection without leakage. The deltoid muscle can also simulate intramuscular injection practice. During puncture injection practice, there will be obvious frustration after injection. If the puncture is correct, there will be significant blood return. The same puncture site of veins and skin can withstand hundreds of repeated puncture exercises without leakage. It is suitable for the training of arm venipuncture injection in medical colleges, hospitals, nursing and recuperation institutions.
