A puncture training device for intravenous anesthesia

Abstract

The utility model relates to medical instrument technical field especially is a puncture training device for intravenous anesthesia, the utility model discloses a high simulation arm model, blood vessel simulation mechanism and puncture simulation mechanism, the inside surface of simulation subcutaneous soft tissue cover is opened along its length direction and is passed through the passage that can supply blood vessel simulation mechanism to pass, blood vessel simulation mechanism includes the simulation blood vessel section below skin puncture piece in the passage, a pair of respectively detachable type is established in the both sides of simulation blood vessel section and is communicated with simulation blood vessel section's communication pipe, is established in one of communication pipe and is used to inject simulation blood in the liquid inlet of communication pipe and is established between two communication pipes and is used to realize the blood pump of simulation blood circulation between simulation blood vessel section and communication pipe, the device solves the problem that simulation blood vessel cannot be replaced after using the prior art device.
