Features:
1. The model lies in supine position, head tilting toward left. Soft material makes real skin touch
2. Clear anatomical landmarks, including clavicle, sternocleidomastoid, suprasternal fossa, umbilicus, groin, inguinal ligament
3. Pulse of carotid and femoral artery are electronically simulated
4. Jugular puncturing, subclavian vein puncturing, external jugular puncturing, femoral vein puncturing could be practiced. An absence of resistance would come when puncturing successfully and simulated blood can be extracted
5. Cardiac floating catheter operation
