1. Simulation model in inclining clinostatism with soft texture, true feeling and realistic appearance.
2. Accurate anatomical positions: such as sternum, xiphoid process, ribs, and intercostal space and so on, which can be obviously felt.
3. Puncture training in pericardial area and inferior to the junction of xiphoid process and the 7th costicartilage is available, and when the puncture needle enters pericardial cavity, there will be liquid with negative pressure.
