1. Simulate patient in horizontal position with soft texture, true feeling and realistic appearance.
2. Correct anatomical landmarks: suprasternal notch, episternal superior border, anterior superior spine and other landmarks can all be distinctly felt, which is easy for puncture location.
3. Available puncture training in anterior superior spine and episternum, and there will be a ”pop” feeling when piercing simulative marrow cavity is done and bone marrow can be extracted.
