Abstract: A simulation manikin (1) for central venous cannulation comprises a first tube (3) for simulating a vein, a simulated clavicle (4), a first member (2) to which the tube (3) and simulated clavicle (4) are removeably affixed to in a position which is anatomically correct with respect to each other and a second member (11) having a surface which simulates the contours of half a neck to the clavicle. The manikin (1) is useful for teaching students identification of key anatomic landmarks, navigation of needle under ultrasound, recognition of correct blood vessels, and avoiding and managing potential complications.
