  • Publication number: 20150024363
    Abstract: A wearable device for simulating wounds and injuries received during a trauma event includes a raiment and vest for covering the torso of a person. The raiment has an outer surface with a color and a texture comparable to human skin. Mounted on the outer surface is at least one wound simulator formed with an orifice that is in fluid communication with a fluid reservoir. Thus, the person can selectively expel a blood-like fluid from the reservoir, and through the wound simulator orifice, to simulate a trauma event. The vest includes an artificial rib cage and prosthetic internal organs juxtaposed with at least one wound simulator to simulate internal effects of a trauma event.
