1. Simulate patient in horizontal and semi-supine positions with soft texture, true feeling and realistic appearance.
2. Correct anatomical location: such as clavicle, armpit and intercostal space of all the ribs and so on, which can be obviously felt and is easy for puncture location.
3. Liver abscess puncture: find the pressure points around the liver, and there’s an obvious ”pop” feeling for successful puncture, and the simulative liver pus can be extracted.
