1. Simulates an adult’s trauma arm
2. With simulative blood powder, vividly simulates multiple forearm traumatic bleeding, e.g. Gunshot, sharp injury, blast injury, etc. 3. Simualte radial artery pulse
4. Available practice of hemostasis by tourniquet pressure dressing, different pressure leads to different hemostasis effects, and the bleeding speed and the distal artery pulse rate will have corresponding dynamics changes.

5. Pressure changes are displayed in real time during the whole hemostasis process.
