An artery stabilizer device, which is held in place by a technician over a targeted artery using just one or two fingertips of the technician's hand, is provided for stabilizing the artery while the user inserts the needle of a syringe into the artery. A pair of stabilizer fingers, which protrude from the bottom surface of a finger-hold platform, hold the artery in place while the needle is inserted into the artery distal the tips of the stabilizer fingers. In one embodiment, a gauze pad is attached beneath the finger-hold platform, allowing the user to quickly apply a dressing over the wound created by the needle puncture. Another embodiment provides a needle guide between extended stabilizer fingers for stabilizing the needle during the arterial puncture. Each embodiment creates an augmented pulse at the targeted needle insertion site, making it easier for the technician to palpate the pulse there. Arterial line insertions can also be facilitated using this invention.
