Abstract: Apparatus to artificially simulate arteries of a limb for training medical personnel to puncture arteries and veins. The device comprises a hollow arm shaped member constructed of a resilient material having two grooves formed on the exterior thereof in the area of the elbow and wrist simulating the brachial artery and radial artery area. A resilient artery is formed of tubing which is positioned through the hollow bore of the arm and through the grooves in the elbow and wrist area. A latex skin is positioned over the arm to cover the tubing and grooves to simulate the skin. The tubing is attached to a liquid container above the arm to simulate blood and cause a arterial or venous pressure for a lifelike back flow of liquid into the syringe.
